Preexecute JQuery

[Heather Napoleone]

I was wondering if I can preexecute a jquery function before my page publishes.  I want the function to run before it gets publishes.  Putting a preexcute tage around it, does not work.

For example I want to add a class to all images that have a width of less than 200.  I don't want this function to be seen on the published page and just have the class on all the images that are less than 200 in width.

Short answer is no.

If you want to run Server-side JavaScript, you could try Node.js.

Cheers,

Gavin

You could do that with asp. (vbscript or jscript)

Or add an attribute from the image into the image tag as a class.

As Mario said you could use JScript via ASP. However, I do not recommend that.

In most cases you would use a scripting language like PHP and get the image width via attribute. Then you can write it like that:

<img class="<?= (<%att_image_width%> > 200) ? "myclass" : "" ?>" src="<%img_image%>">

In the example above you should make sure that img_image is set or that the check for width can handle an empty value if img_image is not set yet.

Best,

Hilmar
