Answer 2

I found this question which might be useful.

you can get the child element by doing this:

var h1_elt = document.getElementById(h1_elt_id);
var span = h1_elt.getElementsByTagName("span");

You can then use the spans innerHTML as part of the h1 elements innerHTML, i.e.: h1_elt.innerHTML = "new text "+span.innerHTML+""

The only thing you would need to change about your HTML is to give the h1 element an id attribute, then use that in place of h1_elt_id.

Answer 3

The following will work.

var h1 = document.getElementById("h1"),
    children = Array.prototype.slice.call(h1.children),
    newText = document.createTextNode("Hello. ");

h1.innerHTML = "";
h1.appendChild(newText);

while(children) {
    h1.appendChild(children.shift());
}

Basically what you're doing is taking a picture of all the children in a specific element, changing the element completely, then re-appending all the previous children back onto the parent element using the picture we took.

Answer 4

Using jQuery.contents() you can replace the nodeValue similar to this:

$("h1").contents()[0].nodeValue = "new text ";

Answer 5

This is gonna work without jquery:

$title = documento.querySelector('your h1 element');
$title.firstChild.nodeValue = 'New Title text';

Answer 6

$("h1").each(function() {
    var textNode = document.createTextNode("new text");
    this.replaceChild(textNode, this.firstChild);
});
