Guidelines for choosing an Element Id within an attribute tag using jQuery

Check Output and -->question. . I am a beginner in utilizing Bootstrap and JQuery for programming. I am interested in learning how to identify the "id" of an input element that is nested within another element's attribute.
In my code, I am using Bootstrap for popover functionality. When clicking on an <a></a> link, a popover is generated, but I am seeking a way to capture the id of an element inside the data-content attribute of the anchor tag.

The following snippet shows the section where I am selecting the anchor and displaying the popover. Now, I aim to retrieve the id contained within the anchor tag, specifically within the data-content attribute of the anchor element. 

        $("a").popover(
            
        {
             delay:1000,
             html: true,

               

        })

This piece of HTML contains an anchor tag with Bootstrap attributes and an embedded html element within the data-content. I intend to extract the ID of the input element inside the data-content attribute of the anchor tag.

Is there a solution for this?

<a href="#" data-toggle="popover" title="Username:"  data-content='<input id="Uname" data-toggle="popover" data-trigger="focus" data-content="You are Successfull!!!!" type="text"/><input id="btnEdit" type="button" value="Edit" />'></a>

Any suggestions on how to achieve this?
Looking forward to your insights.

Answer №1

Consider creating a new jQuery object for the data-content element by following this code:

    $('a').on('click', function () {
        var content = $(this).data('content');
        var input = $(content);
        window.alert(input.attr('id'));
    });
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.0/jquery.min.js"></script>
<a href="#" data-toggle="popover" title="Username:"  data-content='<input id="Uname" data-toggle="popover" data-trigger="focus" data-content="You are Successfull!!!!" type="text"/><input id="btnEdit" type="button" value="Edit" />'>Click me!</a>

Enhanced with active snippet.

Answer №2

It seems like you have control of the id. To ensure this, all you need to do is include the Id in the encompassing element:

<a href="#" 
   data-toggle="popover" 
   title="Username:"  
   data-target-id="#uname"
   data-content='<input id="uname" data-toggle="popover" data-trigger="focus" data-content="You have Succeeded!!!" type="text"/><input id="btnEdit" type="button" value="Edit" />/'>
</a>

Then during initialization, you can do this:

$anchor.popover({
  html: true,
}).on('shown.bs.popover', function(){
   var $anchor = $(this);
   var id = $anchor.data('target-id');
   $(id).AnotherMethod();
});

Answer №3

An alternative approach would be to extract the data-content attribute value, dynamically generate a corresponding element, and then access its unique identifier. Although this method may not be considered optimal, it is worth considering as a potential solution.
