Replace only text inside a div using jquery

Solution 1:

Text shouldn't be on its own. Put it into a span element.

Change it to this:

<div id="one">
       <div class="first"></div>
       <span>"Hi I am text"</span>
       <div class="second"></div>
       <div class="third"></div>
</div>

$('#one span').text('Hi I am replace');

Solution 2:

Find the text nodes (nodeType==3) and replace the textContent:

$('#one').contents().filter(function() {
    return this.nodeType == 3
}).each(function(){
    this.textContent = this.textContent.replace('Hi I am text','Hi I am replace');
});

Note that as per the docs you can replace the hard-coded 3 in the above with Node.TEXT_NODE which is much clearer what you're doing.

$('#one').contents().filter(function() {
    return this.nodeType == Node.TEXT_NODE;
}).each(function(){
    this.textContent = this.textContent.replace('Hi I am text','Hi I am replace');
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div id="one">
       <div class="first"></div>
       "Hi I am text"
       <div class="second"></div>
       <div class="third"></div>
</div>

Solution 3:

You need to set the text to something other than an empty string. In addition, the .html() function should do it while preserving the HTML structure of the div.

$('#one').html($('#one').html().replace('text','replace'));

Solution 4:

If you actually know the text you are going to replace you could use

$('#one').contents(':contains("Hi I am text")')[0].nodeValue = '"Hi I am replace"';

Or

$('#one').contents(':not(*)')[1].nodeValue = '"Hi I am replace"';

$('#one').contents(':not(*)') selects non-element child nodes in this case text nodes and the second node is the one we want to replace.
