Question

hello i want to pass the value of a function to any other function or make the value of a function global so that it can be called in any other function . but i dnt knw how to do it , tried some codes still no sucess .

here is the function code

function newalbum(val1,loginuser)
{

$.ajax({
type:"GET",
url: 'ajax/album.php?val='+val1+'&& loguser='+loginuser,
success: function(data) {
$("#newalbum1").html(data);
        var ab=$('#ab').val();
        var abc=$('#loginuser').val();
        var action=$('#action').val();

alert(ab);
}
});
}

in this function i want to make the three variables var ab, var abc, var action to be global so that its value can be used in any other function . can any one help?

edit – the value of var ab, var abc, and var action is comming from ajax data that is why i am not able to use those variable directly , it says undefined if i use it directly.

after the varibales value received from ajax in function newalbum . i want to use those varibales inside

 (function( $ ){
 $.fn.Uploadrr = function( options ) {

Answer 1

You can declare the variables in the global scope, and remove var before the ab, abc and action variables. Another method is to prefix the variables with window, the global object.

Method 1:

var ab, abc, action; // In the global scope
...
    ab = ...;        // Inside the function

Method 2:

window.ab = $('#ab').val(); // Inside the function

Note: Unless you’ve got an extremely good reason for it, you usually should not declare global variables.
