How can I change an element's text without changing its child elements?
JavascriptHtmlJqueryJavascript Problem Overview
I'd like to update element's text dynamically:
<div>
**text to change**
<someChild>
text that should not change
</someChild>
<someChild>
text that should not change
</someChild>
</div>
I'm new to jQuery, so this task seems to be quite challenging for me. Could someone point me to a function/selector to use?
If it is possible, I'd like to do it without adding a new container for the text I need to change.

Solution 1 - Javascript
Mark’s got a better solution using jQuery, but you might be able to do this in regular JavaScript too.
In Javascript, the childNodes property gives you all the child nodes of an element, including text nodes.
So, if you knew the text you wanted to change was always going to be the first thing in the element, then given e.g. this HTML:
<div id="your_div">
**text to change**
<p>
text that should not change
</p>
<p>
text that should not change
</p>
</div>
You could do this:
var your_div = document.getElementById('your_div');
var text_to_change = your_div.childNodes[0];
text_to_change.nodeValue = 'new text';
Of course, you can still use jQuery to select the <div> in the first place (i.e. var your_div = $('your_div').get(0);).

Update 2018
Since this is a pretty popular answer I decided to update and beautify it a little by adding the textnode selector to jQuery as a plugin.
In the snippet below you can see that I define a new jQuery function that gets all (and only) the textNodes. You can chain of this function as well with for example the first() function.
I do a trim on the text node and check if it's not empty after the trim because spaces, tabs, new lines, etc. are also recognized as text nodes. If you need those nodes too then simple remove that from the if statement in the jQuery function.
I added an example how to replace first text node and how to replace all text nodes.
This approach makes it easier to read the code and easier to use it multiple times and with different purposes.
The Update 2017 (adrach) should still work as well if you prefer that.
As jQuery extension
//Add a jQuery extension so it can be used on any jQuery object
jQuery.fn.textNodes = function() {
return this.contents().filter(function() {
return (this.nodeType === Node.TEXT_NODE && this.nodeValue.trim() !== "");
});
}
//Use the jQuery extension
$(document).ready(function(){
$('#replaceAll').on('click', () => {
$('#testSubject').textNodes().replaceWith('Replaced');
});
$('#replaceFirst').on('click', () => {
$('#testSubject').textNodes().first().replaceWith('Replaced First');
});
});
p {
margin: 0px;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="testSubject">
**text to change**
<p>text that should not change</p>
<p>text that should not change</p>
**also text to change**
<p>text that should not change</p>
<p>text that should not change</p>
**last text to change**
</div>
<button id="replaceFirst">Replace First</button>
<button id="replaceAll">Replace All</button>
Javascript (ES) eqivilant
//Add a new function to the HTMLElement object so it cna be used on any HTMLElement
HTMLElement.prototype.textNodes = function() {
return [...this.childNodes].filter((node) => {
return (node.nodeType === Node.TEXT_NODE && node.nodeValue.trim() !== "");
});
}
//Use the new HTMLElement function
document.addEventListener('DOMContentLoaded', () => {
document.querySelector('#replaceAll').addEventListener('click', () => {
document.querySelector('#testSubject').textNodes().forEach((node) => {
node.textContent = 'Replaced';
});
});
document.querySelector('#replaceFirst').addEventListener('click', function() {
document.querySelector('#testSubject').textNodes()[0].textContent = 'Replaced First';
});
});
p {
margin: 0px;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="testSubject">
**text to change**
<p>text that should not change</p>
<p>text that should not change</p>
**also text to change**
<p>text that should not change</p>
<p>text that should not change</p>
**last text to change**
</div>
<button id="replaceFirst">Replace First</button>
<button id="replaceAll">Replace All</button>
Update 2017 (adrach):
It looks like several things changed since this was posted. Here is an updated version
$("div").contents().filter(function(){ return this.nodeType == 3; }).first().replaceWith("change text");
Original answer (Not working for current versions)
$("div").contents().filter(function(){ return this.nodeType == 3; })
.filter(':first').text("change text");

See In action
Markup :
$(function() {
$('input[type=button]').one('click', function() {
var cache = $('#parent').children();
$('#parent').text('Altered Text').append(cache);
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="parent">Some text
<div>Child1</div>
<div>Child2</div>
<div>Child3</div>
<div>Child4</div>
</div>
<input type="button" value="alter text" />
Solution 4 - Javascript
<div id="divtochange">
**text to change**
<div>text that should not change</div>
<div>text that should not change</div>
</div>
$(document).ready(function() {
$("#divtochange").contents().filter(function() {
return this.nodeType == 3;
})
.replaceWith("changed text");
});
This changes only the first textnode
Solution 5 - Javascript
Just wrap the text you want to change in a span with a class to select.
Doesn't necessarily answer your question I know, but, probably a better coding practice. Keep things clean and simple
<div id="header">
<span class="my-text">**text to change**</span>
<div>
text that should not change
</div>
<div>
text that should not change
</div>
</div>
Voilà!
$('#header .mytext').text('New text here')
Solution 6 - Javascript
For the specific case you mentioned:
<div id="foo">
**text to change**
<someChild>
text that should not change
</someChild>
<someChild>
text that should not change
</someChild>
</div>
... this is very easy:
var div = document.getElementById("foo");
div.firstChild.data = "New text";
You don't state how you want to generalize this. If, say, you want to change the text of the first text node within the <div>, you could do something like this:
var child = div.firstChild;
while (child) {
if (child.nodeType == 3) {
child.data = "New text";
break;
}
child = child.nextSibling;
}
Solution 7 - Javascript
$.fn.textPreserveChildren = function(text) {
return this.each(function() {
return $(this).contents().filter(function() {
return this.nodeType == 3;
}).first().replaceWith(text);
})
}
setTimeout(function() {
$('.target').textPreserveChildren('Modified');
}, 2000);
.blue {
background: #77f;
}
.green {
background: #7f7;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.0/jquery.min.js"></script>
<div class="target blue">Outer text
<div>Nested element</div>
</div>
<div class="target green">Another outer text
<div>Another nested element</div>
</div>
Solution 8 - Javascript
Simple answer:
$("div").contents().filter(function(){
return this.nodeType == 3;
})[0].nodeValue = "The text you want to replace with"
Solution 9 - Javascript
Here is yet another method : http://jsfiddle.net/qYUBp/7/
HTML
<div id="header">
**text to change**
<div>
text that should not change
</div>
<div>
text that should not change
</div>
</div>
JQUERY
var tmp=$("#header>div").html();
$("#header").text("its thursday").append(tmp);
Solution 10 - Javascript
Lots of great answers here but they only handle one text node with children. In my case I needed to operate on all text nodes and ignore html children BUT PRESERVE THE ORDERING.
So if we have a case like this:
<div id="parent"> Some text
<div>Child1</div>
<div>Child2</div>
and some other text
<div>Child3</div>
<div>Child4</div>
and here we are again
</div>
We can use the following code to modify the text only AND PRESERVE THE ORDERING
$('#parent').contents().filter(function() {
return this.nodeType == Node.TEXT_NODE && this.nodeValue.trim() != '';
}).each(function() {
//You can ignore the span class info I added for my particular application.
$(this).replaceWith(this.nodeValue.replace(/(\w+)/g,"<span class='IIIclassIII$1' onclick='_mc(this)' onmouseover='_mr(this);' onmouseout='_mt(this);'>$1X</span>"));
});
<script src="https://code.jquery.com/jquery-3.0.0.min.js"></script>
<div id="parent"> Some text
<div>Child1</div>
<div>Child2</div>
and some other text
<div>Child3</div>
<div>Child4</div>
and here we are again
</div>
Here is the jsfiddle of it working

I think you're looking for .prependTo().

<div class="inner">Hello</div>
<div class="inner">Goodbye</div>
</div>

Solution 12 - Javascript
Problem with Mark's answer is that you get empty textnodes aswell. Solution as jQuery plugin:
$.fn.textnodes = function () {
return this.contents().filter(function (i,n) {
return n.nodeType == 3 && n.textContent.trim() !== "";
});
};
$("div").textnodes()[0] = "changed text";
Solution 13 - Javascript
This is an old question but you can make a simple function like this to make your life easier:
$.fn.toText = function(str) {
var cache = this.children();
this.text(str).append(cache);
}
Example:
<div id="my-div">
**text to change**
<p>
text that should not change
</p>
<p>
text that should not change
</p>
</div>
Usage:
$("#my-div").toText("helloworld");
Solution 14 - Javascript
2019 vesrsion - Short & Simple
document.querySelector('#your-div-id').childNodes[0].nodeValue = 'new text';
Explanation
document.querySelector('#your-div-id') is used for selecting the parent (the element which text you are about to change)
.childNodes[0] selects the text node
.nodeValue = 'new text' sets text node value to "new text"
This answer is possibly inspired by Dean Martin's comment. Can't say for sure since I've been using this solution for years now. Just thought I should post this probability here because some people care about it more than the fact that this is the best solution.
Solution 15 - Javascript
Javascript approach. select the parent div and we can use the firstChild.textContent
let myDiv = document.getElementById("parentDiv");
myDiv.firstChild.textContent = "** New Text **"
Solution 16 - Javascript
Here's a recursive way:
function changeInnerText(elm,text,newText) {
if (elm == null) {
return;
}
changeInnerTextHelper(elm.firstChild, text, newText);
}
function changeInnerTextHelper(elm, text, newText) {
if (elm == null) {
return;
}
if (elm.nodeType == 3 && elm.data == text) {
elm.data = newText;
return;
}
changeInnerTextHelper(elm.firstChild, text, newText);
changeInnerTextHelper(elm.nextSibling, text, newText);
}
