I want to assign value to the element and auto submit after page completely load.I encounter some question.
1.How to get the element in the tab?
2.How to fire submit event when assigned value?
I want to fire as the follow code:
chrome.tabs.onUpdated.addListener(function (tabId, changeInfo, tab) {
var url = tab.url;
var config = null;
if (tab.status !== "complete") {
return;
}
else {
// assign value and fire submit event
}
});
Help!!
I wouldn't do it this way. Why not use jQuery in a content script and trigger your action on ($document).ready()? That way you'll have the document and can use jQuery selectors to get the elements that interest you. To submit, just get button using a selector and call click().

My extension has a button that injects a stylesheet with insertCSS. When they press the button again, it'll inject the again, causing a repaint. How can I best prevent this?
My current solution: keep an array in the background script with every tabId that has CSS inserted. I remove the tabId from the array when a tab is unloaded. Works fine, but it seems this could be simpler. E.g. window.insertedCSS = true, but doing this from the background script affects all tabs.
You can use a content script to check if the CSS was already injected before actually injecting it, like:
function myButtonClicked(){
chrome.tabs.executeScript({code:`
(function(){
if (window.insertCSS === true) return false; //if already inserted return false;
window.insertCSS = true; //if not, set the page's variable and return it
return true;
})();
`}, function (result) {
if (result[0]) { //if CSS was not inserted, insert it.
chrome.tabs.insertCSS({file:'myCSS.css'});
}
});
}
I have a simple xpage with 2 inputText field (username and password) and a button.
The idea is that when hitting the "return" or "enter" key , that the onclick event of the button will be activated. I guess this is normally done with an auto onfocus, but can't find a way to let this work.
I think best is to define a small function from a js library you load in each page you need this
function fireButton(e, buttonId) {
if (typeof e == "undefined" && window.event) {
e = window.event;
}
if (e.keyCode == dojo.keys.ENTER) {
dojo.byId(buttonId).click();
e.preventDefault();
}
}
Then in the onkeydown attribute you can call it:
<xp:inputText onkeydown="fireButton(event, '#{id:buttonId}')"
From the Button's "All Properties" tab, set type to submit,
I have a p:accordionPanel and inside of each tab of the panel there is some info that the user can manipulate, what i need to do is if the user close the tab show a confirm dialog (before the tab get closed) whit something like "are you sure you wanna close the tab? if you do your changes will be lost". here is what i tried
<p:ajax event="tabClose" onstart="return myFunction()"
listener" {myBean.myMethod}" process="#this" />
function myFunction() {
var answer = confirm("are you sure you wanna close the tab? if you do your changes will be lost");
if(answer){
//some logic
return true;
}else{
//some logic
return false;
}
}
The problem is that if i choose cancel on the confirm dialog the tab get close anyway. Shouldn't the tab closing be canceled by the onStart="return false"? is there a way to achieve what i'm trying to do?
Finally I solved my problem, apparently the onStart="return false" does not prevent the tab from change its statatus but the onTabChange attribute of the p:accordionPanel does, the only problem is that for some reason the onTabchange event of the accordion don't get execute when the tab is been closed just when the tab is been opened so i have to override the acordionPanel unselect function of primefaces to call the onTabChange event
PrimeFaces.widget.AccordionPanel.prototype.unselect = (function(index) {
var cached_function = PrimeFaces.widget.AccordionPanel.prototype.unselect;
return function() {
var panel = this.panels.eq(index);
if(this.cfg.onTabChange) {
var result = this.cfg.onTabChange.call(this, panel);
if(result === false)
return false;
}
var result = cached_function.apply(this, arguments);
return result;
};
})();
then i only had to placed myFunction(); on the onTabChange event of the accordiong panel (onTabChange="return myFunction()")and it works.
I need a page action popup icon to appear when a tab has a specific URL in the address bar.
I have this in my background page
chrome.tabs.query({url:"MYURL.COM"} , function(tab)
{
for(i=0;i<tab.length;i++)
{
console.log(tab[i].id);
chrome.pageAction.show(tab[i].id);
}
});
The popup shows whenever I reload the extension but as soon as user refreshes, it goes away and doesn't come back.
The reason is that the background.js page is only loaded once, so you need to add a listener to every time the page tab is updated to check whether the page action should be shown, something like this:
chrome.tabs.onUpdated.addListener(function (tabId, changeInfo, tab) {
if (tab.url.indexOf("MYURL.COM") > -1) {
chrome.pageAction.show(tabId);
}
});
There is no reason to iterate over each tab as you have done.
As Adam has already said, the tabs.onUpdated event is the way to do it.
Anyway, it [seems like I'm not the only one who experienced that the tabs.onUpdated event doesn't always fire when it should - even when waiting for complete status.
So if you're having the same issue, you might want to try my modified version that has proven reliable for me 100%.
chrome.tabs.onUpdated.addListener(function(tabId, change) {
if (change.status == "complete") {
chrome.tabs.query({active: true}, function(tabs) {
var tab = tabs[0];
// Now do stuff with tab .. Eg:
if (tab.url.indexOf("MYURL.COM") > -1) {
chrome.pageAction.show(tab.id); }
else {
chrome.pageAction.hide(tab.id); }
});
}
});
Use chrome.tabs.onUpdated to listen to new tabs and tab reloads of the domain you are interested in.
I have done a few searches for this issue and I have come up empty handed. I hope somebody can clarify things for me and point me in the right direction.
Problem: I have a page that displays a list of results after submitting a search form. When a user clicks on one of the results, the browser goes to a new page showing more information about the result. When the user then clicks the 'back' button to go pack to the results, my browser reloads the page and shows the top of the page instead of the result that was last clicked.
Goal: What I would like is this: when the user click's the back button, the browser should go back to the previous page and, instead of showing the top of the page, show the page at the previous position.
Solution: I am completely lost as how this result can be achieved. Could it have something to do with javascript, or headers sent to the browsers, maybe something to do with caching.
If this is incredibly important, I'd suggest investigating the following:
add ids to each outgoing link
use JavaScript to capture the onClick for the links
when a link is clicked, redirect the user to that link's id fragment identifier, then link out as desired
When the user hits the back button, they'll return to that specific link, e.g. http://www.example.com/#link27 instead of http://www.example.com/
You may be able to get some ideas from here:

You can use javascript and jquery to set the scroll position of the window and cookies to store the position to scroll to. In the javascript of the page with the search results you could have something like this:
var COOKIE_NAME = "scrollPosition";
$(document).ready( function() {
// Check to see if the user already has the cookie set to scroll
var scrollPosition = getCookie(COOKIE_NAME);
if (scrollPosition.length > 0) {
// Scroll to the position of the last link clicked
window.scrollTo(0, parseInt(scrollPosition, 10));
}
// Attach an overriding click event for each link that has a class named "resultLink" so the
// saveScrollPosition function can be called before the user is redirected.
$("a.resultLink").each( function() {
$(this).click( function() {
saveScrollPosition($(this));
});
});
});
// Get the offset (height from top of page) of the link element
// and save it in a cookie.
function saveScrollPosition(link) {
var linkTop = link.offset().top;
setCookie(COOKIE_NAME, linkTop, 1);
}
// Boring cookie helper function
function getCookie(name) {
if (document.cookie.length > 0) {
c_start = document.cookie.indexOf(name + "=");
if (c_start != -1) {
c_start = c_start + name.length + 1;
c_end = document.cookie.indexOf(";", c_start);
if (c_end ==- 1) c_end = document.cookie.length;
return unescape(document.cookie.substring(c_start, c_end));
}
}
return "";
}
// Another boring cookie helper function
function setCookie(name, value, expiredays) {
var exdate = new Date();
exdate.setDate(exdate.getDate() + expiredays);
document.cookie = name + "=" + escape(value) +
((expiredays==null) ? "" : ";expires=" + exdate.toGMTString());
}
This assumes your search result links have class="resultLink".
The first part of the answer is that you use anchors to land on a page somewhere other than the top. So if I have this in my html at the bottom of my page:
<a name="f"></a>
then I can have the user land there by appending the anchor to the end of he url:
http://www.bullionvalues.com/glossary.aspx#f
So, if you are talking about ASP.Net you can place the anchor in a hidden field on the page info page and then read it from the search page by using: Page.PreviousPage property.
protected void Page_Load(object sender, EventArgs e)
{
if (Page.PreviousPage != null)
{
Object o = PreviousPage.FindControl("hfAnchor");
if (o != null)
{
HiddenField hf = o as HiddenField;
Response.Redirect(Request.Url+"#"+hf.Value);
}
}
}
I fixed this issue by sending headers with php. This was my solution:
header("Expires: 0");
header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT");
header("Cache-Control: store, cache, must-revalidate");
header("Cache-Control: post-check=0, pre-check=0", FALSE);
Thanks to everybody for the help.
