How to Dynamically Change Element Text Without Affecting Child Nodes

When aiming to update the text content of an element without altering its child elements, one might encounter challenges as a beginner in jQuery. This article offers guidance on approaches to achieve this task effectively.

Using ChildNodes Property

In JavaScript, the childNodes property provides access to all child nodes of an element, including text nodes. This enables you to identify and modify the desired text content while preserving the child elements. For instance, consider the following HTML structure:

<div>
<p>To update the bolded text, you can employ JavaScript as follows:</p>
<pre class="brush:php;toolbar:false">let your_div = document.getElementById('your_div');

let text_to_change = your_div.childNodes[0];

text_to_change.nodeValue = 'new text';

By leveraging the nodeValue property, you can modify the text content without impacting the p elements. Note that you can use jQuery to select the div initially, utilizing var your_div = $('your_div').get(0);.
