Jquery : Linking external .js file

If your external js method is not called then there should be 2 problems.

Problem 1

It looks like jquery.js contains the code you wrote that depends on jQuery.

Solution:

You need to load jQuery before your external js file.

---

Problem 2

 User defined function is not in $(function() {

/* your function */

});

$(document).ready() function. Everything inside it will load as soon as the DOM is loaded and before the page contents are loaded.

 $(document).ready(function() {

   // some code here

 });

$(document).ready(function() {

   // other code here

 });

 $(document).ready(),  you can write $(function(){ ... }) instead, like so: 

  $(function() {

   // do something on document ready

 });

 

Solution:

Add the below code.

$(function ()  

{ 

 /* your function */ 

});
