getJson同步

$.ajaxSettings.async = false;//在执行之前加$.ajaxSettings.async = false; (同步执行)

 1 function get_no_order_array() { 
 2   var order_info = show_order(); 
 3   var order = []; 
 4   $.ajaxSettings.async = false;//在执行之前加$.ajaxSettings.async = false;  (同步执行) 
 5   $.getJSON("../JSON/customers.json", function (date) { //<span style="line-height: 1.5;">$.getJSON不懂的话可以看一下我之前的博客，或是专门学习一下  “JSON”</span> 
 6 date["man"].forEach(function (person) { 
 7       if (order_info.k_obj[person] == undefined) { 
 8         order.push(person); 
 9       } 
10     }) 
11   }); 
12   $.ajaxSettings.async = true;//执行你的代码之后及时恢复为$.ajaxSettings.async = true； （异步执行） 
13   return order; 
14 }
