I use the jQuery-ui tabs widget as a navigation. Contents of all tabs are load via ajax. Seems that there is interference between tabs. I mean, for example, if in page1 in tab1, there is an element whose ID is foo, and in page2 in tab2, there is an element with the same ID. And in both page, there is javascript code to manipulate the element with ID foo, then weird things will happen.
How to deal with this situation?
You deal with it by having unique IDs - that is, after all the point of IDs. :) As far as jQuery selectors are concerned, yes, you can clarify which of the elements you mean as Bayard Randel explains, but it's a dangerous practice in general. I've found from personal experience that it comes back to bite you in the end - somewhere, somehow, you'll forget that you've got duplicate IDs. Just avoid them.
Seeing as you are using jquery, you can target the correct element by using selectors based on your tab name.
e.g. if you markup looks like this:
<div id="tabs">
<div id="tabs-1">
blah
</div>
<div id="tabs-2">
blah
</div>
</div>
you can specifically select the second link with this selector, despite the id duplication:
$("#tabs-2 #linkId").whatever();

I have a simple pagination that looks like
<ul class="pagination justify-content-end" th:field="*{page}">
<li class="page-item page-item disabled">
<a class="page-link" href="action">1</a>
</li>
</ul>
I would get the following behaviour with Thymeleaf. Clicking on the page and before submitting the action, the value of the th:field associated with the pagination should be changed by setting it to the th:value of the selected page. In other words, clicking on the page number should change the value of "*{page}" and then call the method. Is there any way to do that, for example, combining th:onclick with th:action?
Thymeleaf is a rendering engine, as such it can do nothing once the page is served to the end user. At best u can fill variables into javascript when rendering to achieve the desired result.
As for your described functionality the given code is far to limited or faulty to give a suggestion for a javascript solution, for one th:field on a non-input element doesn't do much. Also the shown href is just a simple href that doesnt interact in any way with the encapsulating th:field.
I am using Dotclear blog software, which provide a widget for the blog categories with a resulting code looking like this:
<div class="widget categories ">
<h3>Catégories</h3>
<ul>
<li>Cat1</li>
<li>Cat2
<ul>
<li>Subcat1</li>
</ul>
</li>
<li>Cat3
<ul>
<li>Subcat2</li>
</ul>
</li>
<li>Cat4</li>
</ul>
</div>
What I am trying to achieve here is using the <a> tag (for Cat2 or Cat3) as header (or a dynamically added <h4> around it) and fold the subcategory list. If I call the accordion like this :
$(".categories").accordion({
header: "li:has(ul) > a",
});
the accordion does work, but when I click on the link it just folds/unfolds the item and doesn’t let me go to the link target (the category page, that is).
I tried wrapping the <a> in an <h4> tag and use that tag as header, but it doesn’t seem to make a difference. Is there a way to do what I seek or should I abandon the idea of collapsing subcategories and have functioning links within the header ?
Thanks for your time.
Well, after reading your comments, I realized I was using the wrong tool to achieve my objective. I have replaced jquery-ui’s accordion with a treemenu jQuery plugin which is actually made for my use. Sorry to have wasted your time and thanks for your kind answers.
All, I'm trying to use the Bootstrap Navbar user choice to control the filtering of posts shown to the user.
The model includes an 'expired' field which is a date-time type.
Three choices are: All (no filtering), Open (show only open issues) and Closed (show closed).
Is there a way to do this without defining three different index.html.erb variants (DRY problem). The filter should show only closed issues if #post.expired < Time.now .. etc.
Stated alternately - can controller 'know' what the user chose, although Navbar, as i am using it, is simply a fancy navigation toolbar?
Thanks for any advice.
Typically this is done by including a parameter in the request, and looking for that parameter in the controller. The bootstrap navbar uses regular anchor links so you should be able to add parameters easily to them (modified example from the doc):
<div class="navbar">
<div class="navbar-inner">
<a class="brand" href="/some_url">List</a>
<ul class="nav">
<li>All</li>
<li>Open</li>
<li>Closed</li>
</ul>
</div>
</div>
You can read the filter parameter in the controller by accessing the value of params[:filter].
In JQuery Mobile, I have a navigation bar like the following:
<div id="nav_bar" data-role="navbar">
<ul>
<li><a>video</a></li>
<li><a>music</a></li>
<li><a>picture</a></li>
</ul>
</div>
Say now I want the nav bar to display "some content" only. This is my code:
$("#nav_bar ul").html("<li><a>some content</a></li>");
But the built-in JQuery Mobile style is not applied to it. How can I do this?
Thanks in advance.
When a page is opened, a script runs to add all the necessary classes. Replacing an item does not rerun the script.
I don't think you can do this without adding in the class manually by either specifying the classes in the text/using a variable or the following:
$("#nav_bar ul").html('<li><a>some content</a></li>').children('li').addClass('class-one class-two');
$("#nav_bar ul").html("<li><a>some content</a></li>");
.html() method destroys ul element and its contents then adds new content.
You should use .append() instead.
$("#nav_bar ul").append("<li><a>some content</a></li>");
If you actually want to replace the original content.
Target the div and use .html() method
$("#nav_bar").html("<ul><li><a>some content</a></li></ul>");
A question similar to this has been posted several time, but I cannot find a solution that works. Hopefully, someone can help!
I am using jQuery Mobile 1.1 and jQuery 1.7.2, so I'm on the most recent stable releases. I want to create a dynamic page header. Using this HTML code, it works fine:
<div data-role="page" id="levela">
<div data-role="header" id="hdr_levela">
<h1>Title</h1>
</div>
</div>
So I then go to dynamically create the title. I change the HTML to this:
<div data-role="page" id="levela">
<div data-role="header" id="hdr_levela">
</div>
</div>
And added the following jQuery code:
// Set the header
var dirHeader = $('#hdr_levela');
dirHeader.append('<h1>' + title+ '</h1>');
The title appears, but is not styled. I have found several posts about this. In the jQuery Mobile Documentation, it says:
"However, if you generate new markup client-side or load in content via Ajax and inject it into a page, you can trigger the create event to handle the auto-initialization for all the plugins contained within the new markup. This can be triggered on any element (even the page div itself), saving you the task of manually initializing each plugin (listview button, select, etc.).
For example, if a block of HTML markup (say a login form) was loaded in through Ajax, trigger the create event to automatically transform all the widgets it contains (inputs and buttons in this case) into the enhanced versions. The code for this scenario would be:
$( ...new markup that contains widgets... ).appendTo( ".ui-page" ).trigger( "create" );
So I tried several things. After the above code, I added the following:
dirHeader.trigger("create");
This had no effect. So I tried to put it on the actual append itself:
dirHeader.append('<h1>' + folderName + '</h1>').trigger("create");
This had no effect. I then tried the process on the parent element (in this case, the id of the parent div is "levela"). So I tried this:
$('#levela').trigger("create");
This also had no effect. At this point, I am completely lost. Every solution involves doing one of the things I have tried and is just not working. I must be missing something incredibly basic but I just can't seem to find it.
Thanks in advance for your help!
You can update the content by calling .page:
See this working Fiddle Example!
// Set the header
var title = 'super hyper BuBu',
$dirHeader = $('#hdr_levela');
$dirHeader.append('<h1>' + title+ '</h1>').page();
I just solved a similar problem -- it appears that jQM headers and footers do not have the "create" method, so as far as I can tell, the css classes and roles need to be added manually.
For reference, I posted an example fix on this (old) question: JQuery Mobile trigger('create') command not working
