How to make javascript variable global

Question

I need to make this data variable global:

$.ajax({
    url: \"get_data.php\",
    cache: false,
    dataType: \'json\',
    data: {},
    succes         


        

Answer 1

Any variable can be "made global" by attaching it as a property of the window.

window.data = data;

You can now access data as a global variable.

Answer 2

Set a variable equal to what you wish data to be equal to. And when giving data its value, reference the variable. Like this:

var obj = {};

$.ajax({
    // ....

    data: obj,

    // ....
});
