Question

I have several jQuery functions on my website but not on every page all of them are required.
All of them are exectued from one XXX.js file for example:

jQuery(function() {
$(".title").slug({
    slug:'slug',
    hide: false
});         });

and if any of the elements is missing the rest of the functions are not executed.
How to execute for example this function only if the element exists?

Answer 1

You could check if the element exists like this:

 jQuery(function() {
   if($('.title').length != 0) { 
   $(".title").slug({
      slug:'slug',
      hide: false
    });
    }
 });
