call javascript function from jquery

Question

I inherited some javascript code. One of them is a function chg(x) which reloads the page after a drop down list's value has been changed.

How do I use jquery to change the drop down list's value and call chg(x) when the value is changed ?

• Servy: At the end of the day all jQuery is doing is defining a bunch of functions in JavaScript. It's not like it's a separate language, it's just a library.

Answer 1

Use the .change method:

$('#myDropdownID').change(function() {
 $(this).val('some value'); //will change the dropdown's selected value to whatever you want
 chg(x);
});

Assuming that the chg() function is somewhere in the code.

Answer 2

You should be able to call chg anywhere where it's valid to call a function, since jQuery IS Javascript.

If chg() doesn't work, then provide us with some code specific to your situation, because it may not be defined in global context or scope such to call it like that.
