create span element

**geargolum** · Jul 30, 2007 11:22

Where could I find examples of what I'm trying to achieve?

I want the JS insert a <span> within an <h2>

I've had no luck with createElement and appendChild

Post the code so we can help you modify it to a working state,

sorry mate, thought i'd be nice and respond to this:

Code:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
      "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
    <head>
        <title>Untitled Document</title>
        <link rel="stylesheet" type="text/css" media="screen" />
    <style type="text/css">
        h2 span {
            color: red;    
        }
    </style>
        <script type="text/javascript">
        function insertSpan() {
        var h2s = document.getElementsByTagName('H2');
        for(var i = 0; i < h2s.length; i++) {
            if((i &#37; 2) == 0) {
                var sp = document.createElement('SPAN');
                sp.appendChild(document.createTextNode(h2s[i].innerHTML));
                h2s[i].innerHTML = '';
                h2s[i].appendChild(sp);
            }
        }
        }
    window.onload = insertSpan;
        </script>
    </head>
    <body>
        
    <h2>Test 1</h2>
    <h2>Test 2</h2>
    <h2>Test 3</h2>
    <h2>Test 4</h2>
    <h2>Test 5</h2>
    <h2>Test 6</h2>
    <h2>Test 7</h2>
    <h2>Test 8</h2>

    </body>
</html>

My test works in both IE and FF.

I usually think when you post a complete solution
the other person is not learning as much !!!!
But I am not against it ...

No need to explain, you get alot of people coming online to get answers to questions given by teachers etc.

Which is all the more reason they should be willing to do some of the work though.

Great solution by the way. Very nicely done.

What if you gave the <h2> an ID and inserted innerHTML into it ??

Code JavaScript:

document.getElementById(YourH2Tag).innerHTML = '<span>Stuff...</span>';

Thanks gRoberts.

that's what I was trying to use...

Code:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
<title>Untitled Document</title>
<style type="text/css">
h2 {color: #006600; }
span { color: #000066; }
</style>
<script type="text/javascript">
function insertSpan()
{

var h2_array = new Array();
var span, txt, temp;

span = document.createElement('span');
txt = document.createTextNode('test');
span.appendChild(txt);

temp = document.getElementsByTagName('h2');
for ( i=0; i<temp.length; i++)
{
	
	h2_array[i] = temp[i];
	alert(h2_array[i].innerHTML);


	h2_array[i].appendChild(span);
	document.body.appendChild(h2_array[i]);
}
}
window.onload=function()
{
	insertSpan();
}
</script>
</head>

<body>

<h2>lorem ipsum</h2>
<h2>lorem ipsum</h2>
<h2>lorem ipsum</h2>
<h2>lorem ipsum</h2>

</body>
</html>

Shaun...

Your solution works if there's only one H2 on a page. But what if he wanted to do the same to every H2?
