Get the ID of the tab (div) being activated

问题

I'm using jquery 1.9 and jquery UI 1.10

I want to be able to get the tab ID when clicking on a tab. For example if I clicked tab named "Second" I want to get "tabs-2" response.

I've done the below code so far:

<script type="text/javascript">
    $(function () {
        $("#tabs").tabs({
            beforeActivate: function (event, ui) {
                alert(/* the id of the tab (div) being activated */);
            }
        });
    });
</script>

<div id="tabs">
    <ul>
       <li><a href="#tabs-1">First</a></li>
       <li><a href="#tabs-2">Second</a></li>
    </ul>
    <div id="tabs-1">
        <p>abcde</p>
    </div>
    <div id="tabs-2">
        <p>fghi</p>
    </div>
</div>

Tested and working with JQueryUI 1.10, how to get the ID of the tab as it is selected:

$("#tabs").tabs({
  beforeActivate: function (event, ui) {
    alert(ui.newPanel.attr('id'));
  }
});

回答2:

var $tabs = $("#tabs").tabs({
    select: function( evt, ui ) {
        $("#current").text( $(ui.tab).attr('href'));
    }
})

UPDATE - Another solution for jquery UI 1.10

    $(function () { $('#tabs').tabs({ 
             activate: function (event, ui) {
             var active = $("#tabs").tabs("option", "active");
             alert($("#tabs ul>li a").eq(active).attr('href')); 
     } 
});

This works for me

$( "#editor_tabs" ).tabs( { 
    activate: function ( event, ui ) {
        $(ui.newTab.find("a").attr("href")).html("Got It");
    }
});

If you want to get something when clicking on tab, use the select event.

$('#tabs').tabs({
  beforeActivate: function(event, ui){
     alert($(ui.tab).attr('href'));
 }
 });

EDIT

Changed 'select' to 'beforeActivate' as it has been removed from version 1.10

I'm guessing you want to know which tab gets activated, and based on that execute various actions.

Rather than fetching ids and attributes from the HTML elements, here is how you do it:

$("#tabs").on("tabsactivate", (event, ui) => {
    if (ui.newPanel.is("#tabs-1")){
        //first tab activated
    }
    else{
        //second tab activated
    }
});

The activate event is not getting called when the tabs get created. For that you'd need to add the "tabscreate" event in the mix, but you get the idea.

Examine the JQueryUI event object (use a browser debugger like Mozilla's Firebug or Chrome developer tools).

$("#tabs").tabs({        
    activate: function( event, ui ) { 
        console.log(event)  //unnecessary, but it's how to look at the event object              
        alert(event.currentTarget.hash)
    }
});

回答7:

var id=$("ulselector li.ui-state-active").attr("aria-controls"));
alert(id);

回答8:

Use aria-controls

alert(ui.newTab.attr("aria-controls"));

回答9:

In my opinion, the easiest way is to add data- to the <li ...> that make up the tabs.

For example:

                <li data-index="2" data-tabname="Notes">
                  <a href="#tabs-Employee-Notes">Notes</a>
                </li>

Then handle the beforeActivate event (if that is the event you are looking at):

$("#jqTabs_EmployeeDetails").tabs({
    heightStyle: "fill",
    beforeActivate: function (event, ui) {
        var n = ui.newTab;

        console.log($(n).data());
    }
});

For example, $(n).data("tabname") would return the tab name. This also allows you to add any other information you need to the tabs. Simplist solution and scalable I believe.

It works for me

$('#divName .ui-tabs-panel[aria-hidden="false"]').prop('id');

回答11:

The easyest way I found is :

$('#tabs .ui-state-active').attr('aria-controls')

This will return the ID from the div witch is active. Remember you must change #tabs to your jquery.tabs ID.
