Hi,

What I am trying to do is build a dynamic url for my src attribute in img element. such as:

 <img id="visionimage" src="javascript:getImageUrl('visionimage','vision.jpg')" alt="vision" /><span>Vision</span>
   
where:
 function getImageUrl(imagetitle)
  {
 
    var siteUrl = getSiteUrl();
    var imageUrl = siteUrl + "/SiteAssets/images/" + imagetitle;
    return imageUrl;
   
  }
 

but this is not working. How to achieve this?

Please help!

Not going to happen - blocked by the browser
Why don't you just run the js when the page is loaded. Storing the image name in data attribute.

<img id="visionimage" data-title="visionimage" data-name="vision.jpg" alt="vision" /><span>Vision</span>

Open in new window


$(document).ready(function() {
      var siteUrl = getSiteUrl();
      $("img[data-src]").each(function() {
           var imagetitle = $(this).data("title"); // visionimage
           var name = $(this).data("name"); // vision.jpg
           var imageUrl = siteUrl + "/SiteAssets/images/" + imagetitle;
           $(this).attr("src", imageUrl);
      });
});

Open in new window

Hi leakim

Unfortunately, I can't use data attributes as I am using IE 8 and it has no HTML5 support. I have to rely on native javascript.

You can still use them, just means your page won't validate.
