• 如何在使用xui xhr时处理错误?
原标题:how do you handle error while using xui s xhr?

Im利用以下代码从外部网站获取某些数据。

<script type="text/javascript">
    xui.ready(function() { 

             var url =  http://www.domain.com/getData.aspx ;
             x$().xhr(url,function(){
                 alert(this.responseText);
             });    
        }
    );
</script>

<>执行>:

我将我的守则更新如下,但即使我得到404份,但背书功能仍然发射,而不是错误功能。

<script type="text/javascript">
    xui.ready(function() { 

             var url =  http://localhost:49617/SalesForceWebservice/Test/Default4.aspx ;
             x$().xhr(url,{
                 method:  get ,
                 async: true,
                 error: function(){
                     alert( error );
                 },
                 callback: function(){
                     alert( success );
                 }
             });
        }
    );

</script>

上述法典只做了一些细微的工作,但今天上午外部网站已经关闭,这造成了网页的故障。 根据这些文件,只有在被称作“Xhr”的人获得200个身份时,才会看上去打背功能。 处理错误500或404的最佳方式是什么?

最佳回答

Have you read the documentation ?

审视“选择}”。 你可以提出以下论点:

<<>Meod>/strong> 可以找到、提出、删除员额。

async Boolean enables an asynchronous request. defaults to false.

浏览量是显示发送参数的缩略语。

error Function is called on error or status that is not 200. (i.e. failure callback).

<<>strong> 职能要求地位200(即成功退约)。
