loading t:dataTable in JSF asynchronously using jQuery - jsf

<t:panelTab label="Detailed View" styleClass="tabFont" rendered="true" id="DetailedView">

var myAmt=document.getElementById(myidVar).value;
var id = 'myForm\\:targetView';
$j.ajax({
async:"false",
cache:"false",

error:function(){
alert('Error Occurred.Please try later');
},
success:function(output){
alert('SUCCESS');
$j('#'+id).load("/pagesmyProj/Home/dingDongHome.jsf");
alert('after reloading grid');
}
});
}
when i execute the code alert message SUCCESS is getting printed and all the server side variables are getting updated.(I came to know this by sysouts). But nothing is really getting changed in the webpage. The alert message "after relaoding grid" is also getting printed. But the grid is not getting reloaded. The server side changes are not getting reflected in the browser.

For start you should add \\ to your id
instead of var id = 'myForm:targetView';
write var id = 'myForm\\:targetView'; otherwise jquery selector by id wont work (you need to escape the :)

You are referencing
$j('#'+id)...
just remove the "j", ex. $('#'+id)...

After a long struggle,I got the error.The url given to the jquery load function is not proper and it should be changed.

POST FORM in node and receive data response back to same webpage

I have a webpage that takes form details, POSTS the data and should then show the results. I'm using express for my routing.
This all works fine by resending the data with the HTML template after the POST but I think there must be a better way by hiding the "results" HTML section then just showing it once the data is known from the form. I've shown a cutdown version of my pages below.
On first load, the page says "your result is undefined", which I would expect but is ugly.
I could remove the "result" section and create a 2nd HTML page to resend from the POST route with it in which would work but I think there must be a better way.
I want to hide the result section on 1st page load then make it appear on the button submit with the result data. I can get the section hide/unhide but I can't get the data results back to display them. On button submit the form results just appear in the weburl www.mywebsite.com/?data almost like a GET request
I have tried using FormData and npm 'form-data' in a POST but can't get it working following these examples https://javascript.info/formdata and https://www.npmjs.com/package/form-data.
My structure in Node is
Router.js file
return res.send(htmlFormTemplate({}));
});
router.post('/css',
[],
async (req, res) => {
let {data} = req.body;
///
result= do some calculation on {data}
///
return res.send(htmlFormTemplate({result}));
});
The htmlFormTemplate is a js file
module.exports = ({result}) => {
return `
<!DOCTYPE html>
<html>
<head>
</head>
<body>
<form class="box" method ="POST">
<inputname="data" />
<button>Submit</button>
</form>
<script>
///tried form processing here
</script>
<section id="Results">
<ul><li>Your result is ${result}</li></ul>
</section>
</body>
</html>
`;
};
I'm self-taught and new so hope this makes sense and thanks for any help/ideas
You can check if the result variable is null before it gets to the section div:
${ result === null ? '' :
`<section id="Results">
<ul><li>Your result is ${result}</li></ul>
</section>`}
Like this, it wont show the result div if result if null.
There is a very simple to solve this problem,
just use some templating engine for ex EJS, its very easy to use and will help you better,
and your result is undefined because your using a promise and it might have happened that the response might have not come and you loaded the page. Just use await
return await res.send(htmlFormTemplate({result}));

Primefaces 5.1 calendar lose focus in the text field after select a date

We are using primefaces 5.1 in the project, in a p:calender after I select a date in the pop up calendar window, the text field will lose focus. The issue caused by this is you can not use tab to focus on next field in the form, it will go to the first element in the form instead. Even the primefaces showcase has this issue:
http://www.primefaces.org/showcase/ui/input/calendar.xhtml
Any suggestion on how to solve it ?
After some search and local testing while waiting for the answer. I comes out a way to fix this.
It is actually a JQuery UI bug (or may be not as it been there since the first version and still got no official fix!). We need to override the jQueryUI datepicker used by primefaces. Make sure to put the import for that custom script in the last facet so it will be pick up as a resource in the last order.
<f:facet name="last">
<h:outputScript name="default/js/customDatePicker.js" />
</f:facet>
Inside the JavaScript code I do the following to merge the _selectDate into datepicker(the change is in the last else) which will over ride the orginal _selectDate without changing the others. It will do the trick for me on Chrome and IE11.
$(document).ready(function () {
$.extend(jQuery.datepicker, {
_selectDate: function (id, dateStr) {
var onSelect,
target = $(id),
inst = this._getInst(target[0]);
dateStr = (dateStr != null ? dateStr : this._formatDate(inst));
if (inst.input) {
inst.input.val(dateStr);
}
this._updateAlternate(inst);
onSelect = this._get(inst, "onSelect");
if (onSelect) {
onSelect.apply((inst.input ? inst.input[0] : null), [dateStr, inst]); // trigger custom callback
} else if (inst.input) {
inst.input.trigger("change"); // fire the change event
}
if (inst.inline) {
this._updateDatepicker(inst);
} else {
this._hideDatepicker();
inst.input.focus();
}
}
});
});

p:remoteCommand returns <eval> twice in ajax response

I try to render a new page in a new window (or tab) with the link I get from a selected page object in an autoComplete component.
After trying multiple options the only chance in my opinion is to use javascript to catch the submit, trigger a remote command, that gives me a javascript call with the link attribute from the page object.
JSF-Snipplet (with reduced attributes in autoComplete)
<h:form id="autoCompleteForm">
<p:autoComplete id="autoComplete" widgetVar="autoCompleteWidget" value="#{pageBean.selectedPage}" />
<p:remoteCommand action="#{pageBean.showPage}" name="showPage" />
</h:form>
some JS:
// form submit
('#autoCompleteForm').on('submit', function(e) {
e.preventDefault();
showPage();
});
// open link
var openLink = function(pageLink) {
window.open(pageLink, '_blank');
};
Bean part for action
public void showPage() {
RequestContext context = RequestContext.getCurrentInstance();
context.execute("openLink('" + selectedPage.getLink() + ".xhtml')");
}
Everything works nice together, but the response contains the eval tag twice.
<partial-response>
<changes>
<update id="javax.faces.ViewState"><![CDATA[2851816213645347690:-2276123702509360418]]></update>
<eval><![CDATA[openLink('target.xhtml');]]></eval>
<eval><![CDATA[openLink('target.xhtml');]]></eval>
</changes>
</partial-response>
I tried different approaches with redirects or returning view names, but that all leads to no satisfying solutions (e.g. URL not changing or no new window).
Problem solved:
I had defined PrimePartialViewContextFactoryin my faces-config before:
<factory>
<partial-view-context-factory>org.primefaces.context.PrimePartialViewContextFactory</partial-view-context-factory>
</factory>
By removing it the application acts like expected.
This also solves a problem (JSON.parse: unexpected non-whitespace character after JSON data) with pagination and sorting in DataTables.

SharePoint: commonModalDialogClose does not close cross-domain dialog

I have a page hosted in 'virtualcasa1' domain opening a modal dialog:
var options = {
title: "Repro",
width: 400,
height: 600,
url: http://domain2:999/sites/blank/_layouts/XDomainTest/XDomainTestTarget.aspx //[1]
//url: http://virtualcasa1/sites/blank/_layouts/XDomainTest/XDomainTestTarget.aspx [2]
};
SP.UI.ModalDialog.showModalDialog(options);
And I have this code to close it:
alert(document.domain);
SP.UI.ModalDialog.commonModalDialogClose(SP.UI.DialogResult.cancel, 'Cancelled clicked');
If both are in the same domain (case [2] above), the dialog closes well, no issues.
But - if target page hosted in the dialog (case [1] above), dialog does NOT close :-(
document.domain above shows the correct domain where page exists.
I suspect I'm facing a cross-domain issue here (duh), but how to fix it? Or am I wrong and issue is not XDomain-related?
Thanks much!
HTML5's postMessage is your answer.
https://developer.mozilla.org/en-US/docs/Web/API/Window.postMessage
Your parent window that initiates the dialog must have the following javascript:
function listener(event) {
//alert(event.data);
if (event.data == 'Cancel') {
SP.UI.ModalDialog.commonModalDialogClose(SP.UI.DialogResult.cancel, 'Cancel clicked');
}
else {
SP.UI.ModalDialog.commonModalDialogClose(SP.UI.DialogResult.OK, event.data);
}
}
if (window.addEventListener) {
addEventListener("message", listener, false)
} else {
attachEvent("onmessage", listener)
}
Javascript for OK and Cancel buttons in your popup:
<input type="button" value="OK" onclick="parent.postMessage('Message to be displayed by the parent', '*');" class="ms-ButtonHeightWidth" />
<input type="button" value="Cancel" onclick="parent.postMessage('Cancel', '*');" class="ms-ButtonHeightWidth" />
Ajay's answer from the 1st of August 2014 is good, but it needs a bit more explanation. The reason for the failure to close the dialog is simple. Cross site scripting security features of modern browsers disallow a few things, one of which is the use of window.frameElement from within the framed window. This is a read-only property on the window object and it becomes set to null (or with IE, it actually throws an exception when you try to access it). The ordinary Cancel event handlers in the modal dialog conclude with a call to window.frameElement.cancelPopup(). This will fail of course. The ordinary Save handler where the Save worked on the server side results in SharePoint sending back a single line as the replacement document, which is a scriptlet to call window.frameElement.commitPopup(). This also will not work, and it's a real pain to overcome because the page has been reloaded and there is no script available to handle anything. XSS won't give us access to the framed DOM from the calling page.
In order to make a cross domain hosted form work seamlessly, you need to add script to both the page that opens the dialog and the framed page. In the page that opens the dialog, you set the message listener as suggested by Ajay. In the framed form page, you need something like below:
(function() {
$(document).ready(function() {
var frameElement = null;
// Try/catch to overcome IE Access Denied exception on window.frameElement
try {
frameElement = window.frameElement;
} catch (Exception) {}
// Determine that the page is hosted in a dialog from a different domain
if (window.parent && !frameElement) {
// Set the correct height for #s4-workspace
var frameHeight = $(window).height();
var ribbonHeight = $('#s4-ribbonrow').height();
$('#s4-workspace').height(frameHeight - ribbonHeight);
// Finds the Save and Cancel buttons and hijacks the onclick
function applyClickHandlers(theDocument) {
$(theDocument).find('input[value="Cancel"]').removeAttr('onclick').on('click', doTheClose);
$(theDocument).find('a[id="Ribbon.ListForm.Edit.Commit.Cancel-Large"]').removeAttr('onclick').removeAttr('href').on('click', doTheClose);
$(theDocument).find('input[value="Save"]').removeAttr('onclick').on('click', doTheCommit);
$(theDocument).find('a[id="Ribbon.ListForm.Edit.Commit.Publish-Large"]').removeAttr('onclick').removeAttr('href').on('click', doTheCommit);
}
// Function to perform onclick for Cancel
function doTheClose(evt) {
evt.preventDefault();
parent.postMessage('Cancel', '*');
}
// Function to perform onclick for Save
function doTheCommit(evt) {
evt.preventDefault();
if (!PreSaveItem()) return false;
var targetName = $('input[value="Save"]').attr('name');
var oldOnSubmit = WebForm_OnSubmit;
WebForm_OnSubmit = function() {
var retVal = oldOnSubmit.call(this);
if (retVal) {
var theForm = $('#aspnetForm');
// not sure whether following line is needed,
// but doesn't hurt
$('#__EVENTTARGET').val(targetName);
var formData = new FormData(theForm[0]);
$.ajax(
{
url: theForm.attr('action'),
data: formData,
cache: false,
contentType: false,
processData: false,
method: 'POST',
type: 'POST', // For jQuery < 1.9
success: function(data, status, transport) {
console.log(arguments);
// hijack the response if it's just script to
// commit the popup (which will break)
if (data.startsWith('<script') &&
data.indexOf('.commitPopup()') > -1)
{
parent.postMessage('OK', '*');
return;
}
// popup not being committed, so actually
// submit the form and replace the page.
theForm.submit();
}
}).fail(function() {
console.log('Ajax post failed.');
console.log(arguments);
});
}
return false;
}
WebForm_DoPostBackWithOptions(
new WebForm_PostBackOptions(targetName,
"",
true,
"",
"",
false,
true)
);
WebForm_OnSubmit = oldOnSubmit;
}
applyClickHandlers(document);
}
});
})();
This solution makes use of the jQuery library, which our organization uses extensively. It is our preferred framework (chosen by me). I'm sure someone very clever could rewrite this without that dependency, but this is a good starting point. I hope someone finds it useful, as it represents a good two days work. Some things to note:
SharePoint does a postback on all sorts of events on the page, including putting the page into edit mode. Because of this, it makes more sense to trap the specific button clicks, both on the form and in the ribbon, rather than wholesale redefinition of, for example, the global WebForm_OnSubmit function. We briefly override that on a Save click and then set it back.
On any Save click event, we defeat the normal posting of the form and replace that with an identical POST request using AJAX. This allows us to discard the returned scriptlet when the form was successfully posted. When the form submission was not successful, perhaps because of blank required values, we just post the form properly to allow the page to be updated. This is fine, since the form will not have been processed. An earlier version of this solution took the resulting HTML document and replaced all of the page contents, but Internet Explorer doesn't like this.
The FormData api allows us to post the form as multipart-mime. This api has at least basic support in all modern browsers, and there are workarounds for older ones.
Another thing that seems to fail in the cross domain hosted dialog is the scrolling of the content window. For whatever reason, the height is not set correctly on the div with id s4-workspace, so we also set that in the solution.
EDIT:
Almost forgot. You may also need to add this control to your framed ASPX page, which can be done with SharePoint Designer:
<WebPartPages:AllowFraming runat="server"/>
I have exactly the same issue - a dialog opening a view page for an item works fine when opened from a site collection on the same web app/domain, but the Close button fails to work when opening the same item from a site collection hosted in a separate web application. I'm assuming it is a cross-domain thing so I've altered the solution to accomodate this restriction, however, I'm not 100% happy about it as it does make the overall solution a little awkward to use from a user-perspective. I've put the issue to one side for now due to project timescales, but I'm still curious as to why. The only things I can think of is the whole cross-domain thing causing it and that maybe it is there by design to prevent XSS security holes.

Disable commandButton in JSF

This seems like it should be pretty straightforward but I'm not feeling it.
I have a JSF CommandButton that executes a long running serverside task (10-15 seconds). I've seen forms where the button context changes after it's been clicked (The label on the button changes and the button becomes disabled until the processing is complete).
I'm using ICEFaces and have the disabled property set to a boolean on the underlying page code.
The action listener bound to the button changes that boolean to disable it but alas, no changes on the JSP.
Anyone?
What you can do is to change the status of the button using Javascript:
<h:commandButton ... onclick="this.disabled=true"/>
Edit regarding the comment:
If the previous code does not submit the form, then you have to disable the button a little time after the click, not "during" the click itself. You can do that using the following code:
<h:commandButton ... onclick="setTimeout('this.disabled=true', 100);"/>
I'm not sure if the fact to use the this keyword directly in the setTimeout method will work correctly. If not, you can use another way to do that:
<h:commandButton ... onclick="disableButton(this.id);"/>
with the following Javascript function:
function disableButton(buttonId) {
setTimeout("subDisableButton(" + buttonId + ")", 100);
}
function subDisableButton(buttonId) {
var obj = document.getElementById(buttonId);
if (obj) {
obj.disabled = true;
}
}
(I'm sure this code can be enhanced, thus)
You should use an ice:commandButton instead of h:commandButton, since it has the partialSubmit property, which will perform the action as an AJAX call. This should refresh your button's state, so if the property on the server has been set to false, your button should be disabled.
do a javascript submit(); first and then disable the button
Similar to the solution from romaintaz
For a Firefox specific solution, the following works (it does not work in IE):
<h:commandButton ... onclick="disableButton(this.id);" />
Using Javascript function:
function disableButton(buttonId) {
var obj = document.getElementById(buttonId);
if (obj) {
setTimeout(function(thisObj) { thisObj.disabled=true; }, 50, obj);
}
}
do it after icefaces has updated the DOM. you can use ice.onAfterUpdate(callback):
Here with jQuery
ice.onAfterUpdate(function(){
updateButtons();
});
function updateButtons(){
if(!isButtonEnabled()){
jQuery(".myButton").attr('disabled', true);
jQuery(".myButton").removeClass("iceCmdBtn").addClass("iceCmdBtn-dis");
}else{
jQuery(".myButton").removeAttr('disabled');
jQuery(".myButton").removeClass("iceCmdBtn-dis").addClass("iceCmdBtn");
}
}
