Get ajax value outside function

Question

im trying to pass a value out of a get jQuery function here is the example:

function a(){

   var test="";    

   $.get("js/getDATEinvoice.php?inv=" + invoice, function(html) {               
      test=html;            
   });

alert(test);
}

I have tried with returns and i just can not get the value...

I have to call the function inside a function so it can get the value and proceed doing stuff.

Thanks in advance!

The `A` in `AJAX` stands for *asynchronous*. You can't get the value immediately after you start the ajax call because it isn't done yet. You need to access it inside a callback. — Matt Burland, Apr 02 '14 at 15:47

Do this:

$.get("js/getDATEinvoice.php?inv=" + invoice, function(html) {               
      test=html;  
      alert(test);          
   });

A in Ajax means asynchronous. Also the function isn't guaranteed to return something from the result when called.

You just need to declare your variable outside the function scope

 var your_Var = '';
 function yourFunc(){
      your_Var =1;

 };
 alert(your_Var);
