问题描述
假设在服务器上显示了 www.example.com/some.html 网页.现在,我想从另一个域获取该页面的body标签内的内容.我该怎么做?我试图找到解决方案,但是还没有运气.
Suppose a webpage www.example.com/some.html hosed on server. Now I want to get the content inside body tag of that page from another domain. How can I do it? I tried to find solution, but no luck with that yet.
以下是我思考和发现的一些方法.第一个可以从同一站点获取标签的内容.
Here are some ways that I thought and found.First one can get content of a tag from same site.
$.get("link.html", function(data) {
var html = $('<div>').html(data);
var content = html.find("div#some_div_id").html();
//do something
$("#Container").html(content);
});
我尝试过,但对我不起作用.我认为是因为我的跨域请求.
I tried, but doesn't work for me. I think it's because of my cross domain request.
第二个想法是使用iframe.想要将页面加载到iframe中并提取主体标签.但是找不到关于如何检测iframe完成加载页面的事件的任何解决方案?或者如何从iframe加载的页面中获取内容?
Second idea is using iframe. Wanna load the page into iframe and extract body tag. But can't find any solution regarding how can I detect the event that iframe completed loading the page? Or how can I get the content from an iframe loaded page?
谁能告诉我如何以一种简单的方式从body标签中获取那些内容?像我的第一个示例一样,有什么解决方案吗?请帮助...
推荐答案
如果没有服务器端代理来请求其他站点的内容,这是不可能的.由于相同的原始政策,Javascript无法发出跨域请求.您只能使用iframe或AJAX(仅服务器端代理)来做到这一点.
This is not possible without a server-side proxy to request the other site's content; Javascript is not capable of making cross domain requests due to the same origin policy. You can't do this with an iframe or AJAX, server-side proxy only.
