用图像更改li内的文本

Question

I want to change the text inside a li. But this li has got an img. Here the html:

<div>
<ul>
<li><b><img src="../../../Images/folder1/image1.png">Text1</b><i>0</i></li>
<li><b><img src="../../../Images/folder1/image2.png">Text2</b><i>1</i></li>
<li><b><img src="../../../Images/folder1/image3.png">Text3</b><i>2</i></li>
<li><b><img src="../../../Images/folder1/image4.png">Text4</b><i>3</i></li>
<li><b><img src="../../../Images/folder1/image5.png">Text5</b><i>4</i></li>
</ul>
</div>

I am trying this:

$("li").each(function () {
$(this).text(sometext);
})

But it is replacing all, including the img. I only want to change the text: Text1,Text2,...

Any ideas?

Thanks!

Answer 1

To get to the textnodes within an element you need to use contents() and then filter() by nodeType. You can then use replaceWith() to change the text. Try this:

$('li:first b').contents().filter(function() {
    return this.nodeType == 3;
}).replaceWith('foo');

I obviously hard-coded this to use the first li element, but you can change the selector as needed.

You could also do it like this:

$("li b").each(function () {
   this.childNodes[1].textContent = "32323";
})

Answer 3

Store the image in a separate variable and after replacing the text prepend the image back.

$("li b").each(function () {
    var $img = $(this).find('img'); 
    $(this).text(sometext).prepend($img);
})
