Consider the following code
function populateLayout(scopeGroupId){
Liferay.Service.Portal.Layout.getLayouts(
{
groupId: scopeGroupId,
privateLayout: false
},
function(layouts){
for(var i=0;i<layouts.length;i++){
var layout = layouts[i];
alert(layout.name);
}
}
);
}
As you can see from the above Liferay's JSON service API to get all the layouts. I particularly need layout name to populate in a select box. I know that the name is stored as xml string to support different locales. I was wondering if there is javascript api to get just the name of the layout using this xml string and language id. There is a java api for doing the same as below. I need equivalent javascript API if any.
layout.getName(locale)
or
LocalizationUtil.getLocalization(String xml, String languageId)
I believe there is no such utility on Liferay's JavaScript libs.
Most of the times people need to do it in Liferay, they just parse the content in the server side and send the parsed content to the client. Frequently, the client only needs the value in the default locale; if it needs more, the developer finds a way to write it in HTML itself. See e.g. the input-localized tag where the developer writes the code to create a JS object directly in the output.
This makes sense: parsing XML is resource-costly so one would rather avoid it on client-side JavaScript. It may be even that there is a utility to do that in Liferay but I'd propose an alternative approach: just ask what you want to use in your JavaScript and write it in the HTML. For example, instead of writing the following JavaScript code
var names = Liferay.Util.Localization.nonExistentMethodToGetLocaleMap(layout.name);
for (var locale : names) {
alert(names[locale]);
}
decide in server-side which layouts to display and write the following JSP code:
Map<Locale, String> names = layout.getNameMap();
<script>
<% for (String name : names.values()) { %>
alert('<%= name %>');
<% } %>
</script>
Not much clear, I agree, but rather efficient.

I'm creating the Angular app which lets user save his html code (maybe it has style and script tag to control the view) and there is a live preview next to it. User can save the code and other users can come to see the code and the preview. I also worry about the security because of script tag and I want the script to work only with the code that user provides (Not allow to control or get the data in the parent frame). So I need some suggesting of how to do it.
I have tried the preview with iFrame by giving the value through the 'srcdoc' property, but it looks like the security is bad.
You would not need to use an iframe in that situation, you can just render an HTML string inside of a div element using the innerHtml input like so:
<div [innerHTML]="htmlString"></div>
Where htmlString is a string containing the HTML code. You will have to sanitize the content of that variable with the DomSanitizer.
constructor(private domSanitizer: DomSanitizer){}
...
ngOnInit() {
this.htmlString = this.domSanitizer.bypassSecurityTrustHtml(yourHTMLString);
}
I am trying to build out a harness for a page so that we can write tests against it. What I would like to be able to do is use a CSS selector to find the given element or elements instead of manually modifying the SearchProperties or FilterProperties.For a web test the CSS Selector seems far more intuitive then the SearchProperties do. Is there some mechanism for doing this that I am simply not seeing?
Try this...
https://github.com/rpearsondev/CodedUI.jQueryExtensions/
It adds extension methods to the BrowserWindow object...
var example1 = browser.JQuerySelect<HtmlHyperlink>('a.class1');
var example2 = browser.JQuerySelect<HtmlListItem>('li.class2');
However, I will let you know I'm having issues with it complaining about casting errors regularly.
Try browserWindow.executeJavascript if you return a control you found via css/xpath it returns the relevant uiControl object
const string javascript = "document.querySelector('{0}');";
var bw = BrowserWindow.Launch(new Uri("http://rawstack.azurewebsites.net"));
string selector = "[ng-model='filterOptions.filterText']";
var control = bw.ExecuteScript(string.Format(javascript,selector));
HtmlEdit filter= control as HtmlEdit;
filter.Text = "Alien";
As sjdirect noted, the jQuery extensions are probably the way to go if you want to use those type of selectors.
However, it seems that you may be interested in some abstraction that doesn't require directly setting search / filter properties on the UITestControl objects.
There are good abstractions that do not use the same selectors as jQuery, but provide a readable, consistent approach for finding elements in the page and interacting with them.
I would recommend also looking into Code First and CodedUI Fluent (I wrote the fluent extensions) or even CodedUI Enhanced (CUITe).
These provide query support for that looks like (from CUITe):
// Launch the web browser and navigate to the homepage
BrowserWindowUnderTest browserWindow = BrowserWindowUnderTest.Launch("https://website.com");
// Enter the first name
browserWindow.Find<HtmlEdit>(By.Id("FirstName")).Text = "John";
// Enter the last name
browserWindow.Find<HtmlPassword>(By.Id("LastName")).Text ="Doe";
// Click the Save button
browserWindow.Find<HtmlInputButton>(By.Id("Save")).Click();
I am .Net developer and am looking for example related to creation of dynamic navigation menu in umbraco 7 using .Net user control without using MVC technique and XSLT. I have searched it on google but got not much response on it, examples which i got were using either XSLT or Razor. I have not any experience in MVC and XSLT and looking for technique related to using classic ASP.Net, i.e. without using XSLT and MVC. It will a great help if any one could please provide some useful videos or links with examples which i could refer to.
Thanks

You should really look into the Razor thing. It just TOO simple not to try!
It looks like c# mixed with some HTML. If you really want to stick to .Net UserControls you might miss out on future versions.
Creating navigation in a usercontrol is very difficult because you have 2 options
you need to write out HTML yourself
create some custom model to some 3th party control
Both of these options will never return the exact html as you wanted. Razor (and xslt) on the other hand will.
If you still want try something in a .Net User control anyway, get an instance of the Umbraco Nodes you want. Let's give an example:
using System;
using System.Linq;
using Umbraco.Web;
public partial class UserControls_TestUserControl : UmbracoUserControl
{
protected void Page_Load(object sender, EventArgs e)
{
var cache = this.UmbracoContext.ContentCache;
var rootNodes = cache.GetAtRoot().First().Children;
foreach (var node in rootNodes)
{
Response.Write("<li>" + node.Name + "</li>");
}
}
}
If you want to call this code, don't forget to add a macro, and insert the macro in your template.
Just in case you would like to explore razor, here is an equivalent:
#inherits UmbracoTemplatePage
#{
var homePage = CurrentPage.AncestorOrSelf(1);
var menuItems = homePage.Children;
}
<nav>
<ul>
<li>Home</li>
#foreach (var item in menuItems)
{
<li>#item.Name</li>
}
</ul>
</nav>
This example can be used as a partial view. And can be put in your (Razor) template using: #Html.Partial("NameOfThePartial")
You have to admit, it's not too hard.
I'm writing a very simple Yesod message list that uses AJAX to add new list items without reloading the page (both in the case of other users modifying the database, or the client themselves adding an item). This means I have to encode the HTML structure of the message items in both the Halmet template (when the page loads initially) and the Julius template (for when the dynamic addition happens). They look something like this:
In homepage.hamlet:
$if not $ null messages
<ul id=#{listId}>
$forall Entity mid message <- messages
<li id=#{toPathPiece mid}>
<p>#{showMarkdown $ messageText message}
<abbr .timeago title=#{showUTCTime $ messagePosted message}>
And in homepage.julius:
function(message) {
$('##{rawJS listId}').prepend(
$('<li>')
.attr('id', message.id)
.append('<p>' + message.text + '</p>')
.append($('<abbr class=timeago />')
.attr('title', message.posted).timeago())
.slideDown('slow')
);
}
I'd love to be able to unify these two representations somehow. Am I out of luck, or could I somehow abuse widgets into both generating an HTML response, and filling in code in a JavaScript file?
Note: Of course, I understand that the templates would have to work very differently, since the AJAX call is getting its values from a JS object, not from the server. It's a long shot, but I thought I'd see if anyone's thought about this before.
I think it's something of a AJAX best-practice to pick one place to do your template rendering, either on the server or client. Yesod is (currently) oriented toward doing the rendering on the server.
This can still work with AJAX replacement of contents, though. Instead of getting a JSON response from the POST, you should get a text/html response that contains the result of rendering the template on the server with the values that would have been returned via JSON and then replacing the innerHTML of the DOM node that's being updated.
If you want to support both JSON and HTML responses (to support 3rd party applications via API or something) you would have to make the format of the response be a function of the request; either appending ".json" or ".html" to the URL or including a HTTP header that lists the specific document type required by the client.
It would be nice if Yesod provided a 'jwhamlet' template or something that would render the HTML via javascript in order to support client rendering, but I'm not aware of one. That's not to say there isn't one I'm not aware of, though, so keep an eye open for other answers.
If you wanted to make such a thing, you might try tweaking the hamlet quasi-quote code so that instead of expanding the quasi-quotes to an html-generating function, it expanded them to a JSON-generating function and a pre-rendered chunk of text that's a template in mustache-style such that the JSON returned by the function would provide the correct context for the template to be rendered the way you want.
I have created a JSF page which asks the user to enter a value, and this value is being processed via Applet and create a barcode image based on the inputted value. My problem is how can i get the value from the JSF Page and use it in my Applet.. Thanks!
Use JavaScript. E.g.
<h:inputText ... onchange="updateBarcodeApplet(this.value)" />
...
<applet id="barcodeApplet" ...></applet>
with this JS
<script>
function updateBarcodeApplet(value) {
var barcodeApplet = document.getElementById("barcodeApplet");
barcodeApplet.updateValue(value);
}
</script>
and in Applet
public void updateValue(String value) {
// Do your business here.
}
(yes, all Applet's public methods are just available as is in JS)
Needless to say, using an applet for this job is pretty clumsy. Not all clients support or even appreciate applets. I'd also opt for a simple <img> element with a servlet which returns the image as suggested by Denisk. You just have to update the <img src> by JSF or JavaScript.
Why do you do it in a hard way? You don't really want an applet here, create the image on server, serialize it to response stream and display it as plain image.
