javascript - Execute function after Ajax call is complete

Question

I am new to Ajax and I am attempting to use Ajax while using a for loop. After the Ajax call I am running a function that uses the variables created in the Ajax call. The function only executes two times. I think that the Ajax call may not have enough time to make the call before the loop starts over. Is there a way to confirm the Ajax call before running the function printWithAjax()? I do not want the printWithAjax() function to execute until the Ajax call is complete. Any help will be greatly appreciated.

var id;
var vname;
function ajaxCall(){
for(var q = 1; q<=10; q++){
 $.ajax({                                            
         url: 'api.php',                        
         data: 'id1='+q+'',                                                         
         dataType: 'json',
         async:false,                    
         success: function(data)          
         {   
            id = data[0];              
            vname = data[1];
         }
      });

       printWithAjax(); 

 }//end of the for statement
}//end of ajax call function

Try this code:

var id;
var vname;
function ajaxCall(){
for(var q = 1; q<=10; q++){
 $.ajax({                                            
     url: 'api.php',                        
     data: 'id1='+q+'',                                                         
     dataType: 'json',
     async:false,                    
     success: function(data)          
     {   
        id = data[0];              
        vname = data[1];
     },
    complete: function (data) {
      printWithAjax(); 
     }
    });

  }//end of the for statement
  }//end of ajax call function

The "complete" function executes only after the "success" of ajax. So try to call the printWithAjax() on "complete". This should work for you.
