Dynamically Insert Links Inside Span Tag Using Javascript

Zox picture Zox · Mar 11, 2013 · Viewed 7.3k times · Source

I have this:

<span class="image"><img src="something.jpg"></span>

I want to transform it to that using javascript:

<span class="image"><a href="domain"><img src="something.jpg"></a></span>

It has to be done using javascript in order to hide the affiliate links.

I have tried this script but it seems not to work:

function changespan() {
find all <span> tags;
for each <span> with class="image"{
URL = "http://domain.com"
Create new link to URL;
insert link into <span>;
}       
}

The function is uploaded in file script.js and I load it in this fashion:

<script type="text/javascript" src="script.js"></script>
<script type="text/javascript">
window.onload = changespan;
</script>

EDIT: After this is solved, how could i parse my page to find links in this format: and then assign this value to variable URL. I need to be able to assign first path to URL_1 second to URL_2 and so on.

This is how you can implement it:

function changespan() {
    var spans = document.querySelectorAll('span.image');
    for (var i = spans.length; i--; ) {
        var a = document.createElement('a');
        a.href = "http://domain.com";
        spans[i].appendChild(a).appendChild(a.previousSibling);
    }
}
