jQuery加载问题相同的源策略 [英] jQuery load problems same origin policy

问题描述

我想从另一个站点加载内容(本质上是想检查页面上是否有内容).我知道同样的原产地政策会使这一点变得困难，但是我想知道是否有解决办法.我使用了以下方法: http://api.jquery.com/jQuery.getJSON/

I want to load in content from another site (essentially I want to check if something is on the page). I know the same origin policy makes this difficult, but I was wondering if there is a way around it. I looked into using this: http://api.jquery.com/jQuery.getJSON/

有没有更好，更简单的方法?看起来这仅适用于JSON.

Is there a better, simpler way? It looks like that is only for JSON.

谢谢

推荐答案

您可以使用

dataType: "jsonp"

但是我相信这要求您通过ajax加载的整个页面必须为JSON格式(可能不是).

but I believe this requires that the entire page you're loading via ajax be in JSON format (which it probably isn't).

我用来解决此问题的技术是使用服务器端脚本(例如PHP + CURL)来获取页面(或检查所需信息)，然后在我的设备上使用jQuery ajax调用服务器端脚本(不是跨域脚本)来获取我想要的数据.

The technique I've used to get around this would be to use a server-side script (like PHP + CURL) to get the page (or check for the information I want) and then use a jQuery ajax call on my server-side script (which is not cross-domain) to get the data I want.
