javascript - 是否保证在函数(数据)回调完成其工作后将调用传递给always函数的回调

Question

是否保证在 function(data) 回调完成其工作后将调用传递给 always 函数的回调？

$.get(link, function(data) {
    // Do some stuff
}).always(function() {
    // Will this callback be called after "do some stuff" finished its work?
});

是的，确实如此，请检查以下来自 documentation 的示例:

var jqxhr = $.ajax( "example.php" ) 
.done(function() { 
  alert( "success" );
}) 
.fail(function() { 
  alert( "error" );
}) 
.always(function() { 
  alert( "complete" );
});
