Question

I want to change text between two elements using JQuery, but I don’t have any idea !

for example:

<input type='checkbox' name='ch1'>
    This text must be changed !!!
<input type='checkbox' name='ch2'>

Also, I don’t have any control over this Html code, so I can’t add any IDs or tags.

You can call contents() on the parent element to obtain its child text nodes, then use slice() with index() to locate the text nodes you want to remove. From there on, after() will allow you to add the new content:

var ch1 = $("input:checkbox[name=ch1]"),
    ch2 = $("input:checkbox[name=ch2]"),
    contents = ch1.parent().contents();
contents.slice(contents.index(ch1) + 1, contents.index(ch2)).remove();
ch1.after("The text was changed.");
