JavaScript setTimeOut函数不起作用

Question

I have the following JS code

$(document).ready(function(){
  update_items();
  adjust_size_of_menu();
});

var adjust_size_of_menu = function() {
  // global boolean set in update_items_count();
  if ( !items_updated ) 
  {
     alert("Treatment of update_items() not done yet");
     setTimeOut( function(){ adjust_size_of_menu(); }, 1000);
  }
  // More treatment goes here 
}

As you can see, I am setting a variable in the first function. This variable must be true before I proceed with the execution of the rest of the instructions in the second function.

The problem here is that the first time I go into adjust_size_of_menu() , it shows me the alert, which is fine. After that, it should wait 1 second then re-execute the adjust_size_of_menu() from the beginning until the item_updated boolean is true , then we continue with the rest of the code.

What is the problem with this code? I've already used the same approach elsewhere and worked just fine.

Answer 1

setTimeOut is not a built-in function in javascript. If you've used it elsewhere, it's because you or someone else declared it. The correct spelling is setTimeout . Note the lowercase "o".

javascript是区分大小写的语言，应设置为setTimeout（）
