How can I change an element's text without changing its child elements?

Question

I\'d like to update element\'s text dynamically:

   **text to change**
   
       text t         


        
      

Answer 1

For the specific case you mentioned:

   **text to change**
   
       text that should not change
   
   
       text that should not change
   

... 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

, you could do something like this:

var child = div.firstChild;
while (child) {
    if (child.nodeType == 3) {
        child.data = "New text";
        break;
    }
    child = child.nextSibling;
}
