实现自动完成时出现“this.source 不是函数”错误

Question

$(document).ready(function(){
   var var_name=null;
   $('#id1').click(function(){

      $.ajax({
         type:"GET",
         url:" ggs.erm.servlet.setup5.Page",
         success:function(response){
            var_name=response;
            console.log(response);
         }
      })
   });
   $("#id").autocomplete({source:var_name});
});

This is the Code I am messing with,It says TypeError:this.source is not a function. Where I am wrong,Correct me???

Answer 1

jQuery Ajax methods are non-blocking, so it looks like you're trying to set an auto-complete source before the previous method resolves. You probably want to move the autocomplete assignment into the success method of your .ajax() call.

So, instead of what you have, use:

$.ajax({
    type:       "GET",
    url:        "ggs.erm.servlet.setup5.Page",
    success:    function(response) {
        $("#id").autocomplete({ source: response });
    }
});
