EN

// check the meaning of done, fail, always
    $.getJSON( "url", function() {
    
    }).done(function(){
    
        // your rest of the code
        
    });

$(function(){

    $.getJSON( "url", function() {

    }).done(function(){
        $( document ).trigger( "jsonSuccess", [ "bim", "baz" ] );
    });

    $( document ).on( "jsonSuccess",function(event, var1, var2){
        // will execute after the 'getJSON' success 
    });
    
    // other codes can be execute from here, it will not wait

});
