not not 推 法
原标题:Javascript push method not working

我可以把元素推向工程阵列。 Consolelog正在返回适当的物体,但是,他们赢得的塔被推到阵列...... 我的守则是:

var works = new Array();
    $(window).ready(function()
    {       

        $.getJSON( AJAX/getWorks.php , function(data) {
          $.each(data, function(key, val) {
             console.log(val);
             works.push(val);
          });
        });
        console.log(works);
    });

而json则反对:

Object
date: "2012-04-08 17:53:58"
description: "sadasd"
id: "2"
link: "sadasd"
name: "dsad"
objects: null
position: "2"
__proto__: Object

任何人都看到我做了什么错误? 事先得到答复......

你在你的法典中过早地重播阵列。 <代码>console.log将在jax申请完成之前运行,因为ajax是同步的。

    $.getJSON( AJAX/getWorks.php , function(data) {
              $.each(data, function(key, val) {
                 console.log(val);
                 works.push(val);
              });
              console.log(works); // move this here so the array is logged after the ajax request finishes. 
            });

EDIT

如果你想在加亚克斯请求之后使用这一变量,你可以做如下工作:

设立一个职能,处理贾克斯请求

function getWorks() 
{
    return  $.getJSON( AJAX/getWorks.php , function(data) {
              $.each(data, function(key, val) {
                 works.push(val);
              }); 
} 

然后,你可以做以下工作,以确保阿贾克斯请求已经完成。

 $.when( getWorks() ).then(function(){ 
     // you can access the array in here because the ajax has finished executing
 });
