How to parse HTML & replace Tags in a String using jQuery?

Question

I have a string like this (unminified here for easy reading):

var input='<div id="container" style="max-width: 310px;">
    <div class="popupheadermap">
        <b>YFC</b>
    </div>
    <input checked="checked" id="tab-1" name="tab-group" type="radio">
    <label for="tab-1">Administration</label>
    <input id="tab-2" name="tab-group" type="radio">
    <label for="tab-2">Information</label>
    <div id="content">
        <div id="content-1">
            <td>Id</td>
            <td class="tablerow">1252</td>
        </div>
        <div id="content-2">
            <td>Type</td>
            <td class="tablerow">Gym</td>
        </div>
    </div>
</div>
<div id="EditContainer">
    <button class="editMarker" id="1252"><i aria-hidden="true" class="fa fa-pencil editicon"></i>Edit Location</button>
</div>';

Using jQuery I want to replace the contents of the EditContainer div, so that it becomes:

<div id="EditContainer">
    <button id="1126_1" class="saveCancel"><i class="fa fa-floppy-o editicon" aria-hidden="true"></i>Save Edit</button> 
    <button id="1126_2" class="saveCancel"><i class="fa fa-ban editicon" aria-hidden="true"> </i>Cancel Edit</button>
</div>

But when I use find, with $(input).find('#EditContainer') , I get an empty ouput.

How do I parse this string, and replace the contents of the EditContainer div?

Answer 1

The issue you have is that the #EditContainer element is in the root level of the string, so you need to use filter() , not find() . Try this:

 var input = '<div id="container" style="max-width: 310px;">' + '<div class="popupheadermap">' + '<b>YFC</b>' + '</div>' + '<input checked="checked" id="tab-1" name="tab-group" type="radio">' + '<label for="tab-1">Administration</label>' + '<input id="tab-2" name="tab-group" type="radio">' + '<label for="tab-2">Information</label>' + '<div id="content">' + '<div id="content-1">' + '<td>Id</td>' + '<td class="tablerow">1252</td>' + '</div>' + '<div id="content-2">' + '<td>Type</td>' + '<td class="tablerow">Gym</td>' + '</div>' + '</div>' + '</div>' + '<div id="EditContainer">' + '<button class="editMarker" id="1252"><i aria-hidden="true" class="fa fa-pencil editicon"></i>Edit Location</button>' + '</div>'; var $input = $(input); $input.filter('#EditContainer').html('<button id="1126_1" class="saveCancel"><i class="fa fa-floppy-o editicon" aria-hidden="true"></i>Save Edit</button><button id="1126_2" class="saveCancel"><i class="fa fa-ban editicon" aria-hidden="true"> </i>Cancel Edit</button>'); $input.appendTo('body');
