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
*/
});
