Synchronous Execution Using Ajax Post (Implementation Method)

Generally, when we use AJAX requests, they are asynchronous. After the operation is executed, the parameters cannot be obtained outside the method, but data can be returned when the synchronous execution is used.

The 'ajaxSettings.async' parameter is set, by default it is true, indicating asynchronous, and synchronous is set before the method: 
$.ajaxSettings.async = false; At this point, after the method is executed, the corresponding data can be returned.

Code block

/** * Get the list */
function flowAtoms(){  
//Request interface 
  var listUrl = getServerUrl('XXXXXXX'); 
  var param = {};
  $.ajaxSettings.async = false;  
   newlist="";  
  $.post(listUrl,param, function(data){   
    // Return the Json conversion    
     var data_json = $.parseJSON(data);  
    if(data_json.status==200){       
      // Initialize operation options      
      var data=data_json.data;      
      var funcHtml="";     
      $.each(data,function(i,v){        
        funcHtml+=v.name;  
       )     
      newlist = funcHtml;     
    } else {        
      alert(data_json.message);    
    }  
  ) 
  //Return the global variable newlist
  return newlist;
}
