I have big html document with various images with href and src.

I want to declare their href and src so as to change only their var values. something like...

<script>

var imagehref = www.url.com; 

var imagesrc = www.url.com/img.pg; 

</script>



HTML Part:



<html>

<a href=imagehref><img src=imagesrc /> </a>

</html>

What is the correct syntax/way to do it?

You can't do it in this way, you have to set href and src directly from the js script. Here's an example:

<html>

  <body>

    <a id=dynamicLink href=><img id=dynamicImg src= /> </a>

  </body>

  <script>

    var link = document.getElementById('dynamicLink'); 

    link.href = http://www.url.com

    var img = document.getElementById('dynamicImg'); 

    img.src = http://www.url.com/img.png

  </script>

</html>
