铬的扩展怎么可以基本上是 CURL 其他页面? [重复]
原标题:How can Chrome extensions basically cURL other pages? [duplicate]

我想写一个铬扩展名, 需要在某个网站的某个动态页面上, 抓取一些链接, 分析链接页面的内容。

事实上,我对撰写浏览器扩展不太了解,所以我想先看看它是否可行,然后我承诺学习如何学习。我知道扩展通常会执行 Javascript, 但我不知道如何用 Javascript 取得这样的结果。

问题回答

使用 jquery ajax 获取其它页面的内容 。

您可以使用 < a href=" "http://jquery.com" rel="nofollow" >jQuery 和 < a href="http://james.padolsey.com/javascript/cross-domain-reques-with-jquery/""rel="nofol="

$.ajax({
    url:  http://example.com ,
    type:  GET ,
    success: function(res) {
        var contents = $(res.responseText);
    }
});

使用该内容对象,您可以对 jQuery 对象做任何正常操作, 例如 < a href=" http://api.jquery.com/find/" rel=" nofollow"\\code> find () 。 例如, 如果您想要获得该页面的标题, 您可以 :

$.ajax({
    url:  http://example.com ,
    type:  GET ,
    success: function(res) {
        var contents = $(res.responseText);
        var title = contents.find( title ).text();
    }
});
