I need to make this data variable global:
$.ajax({
url: "get_data.php",
cache: false,
dataType: 'json',
data: {},
success: function(data) {
for(var i = 0; i < data.results.length; i++) {
if(my_data.hasOwnProperty(data.results[i].id)) {
my_data[data.results[i].id].name = data.results[i].name;
}
}
});
I want to have this globally declared. Do I need to declare it as array?

Global Variables are the variables that can be accessed from anywhere in the program. These are the variables that are declared in the main body of the source code and outside all the functions. These variables are available to every function to access. Var keyword is used to declare variables globally.
Global ScopeGlobal variables can be accessed from anywhere in a JavaScript program. Variables declared with var , let and const are quite similar when declared outside a block.
Normally, when you create a variable inside a function, that variable is local, and can only be used inside that function. To create a global variable inside a function, you can use the global keyword.
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.
