如何使用MooTools和Request.HTML从远程页面获取元素？

问题描述

我正在使用MooTools（项目的一部分）使用 Request.HTML 加载页面，除非我不想要整个页面，一个有id的片段。

I'm using MooTools ( part of the project ) to load a page using Request.HTML which works fine except that I don't want the whole page, just one fragment which has an id.

这是有问题的代码

var req = new Request.HTML({
    onSuccess: function( res ) {
        // according to the docs
        // res should be the node list of the remote response
        // I want to grab #myFragment

        var f = res.getElementById('myFragment');
        // res.getElementById is not a function

        var f = $(res).getElementById('myFragment');
        // $(res) is null ?

        var f = $$(res).getElementById('myFragment');
        // [null, null] ??


        // more code

    }
}).get('/myurl');

我很确定这一定是可行的，我可以抓住有类的元素。有谁知道怎么做。

I'm pretty sure this must be possible, I can grab elements that have a class. Does anyone know how to do this.

谢谢）

I hopped onto the #mootools channel on irc.freenode.net and got my answer from <kamicane> himself

var req = new Request.HTML({
    onSuccess: function( responseTree, responseElements /*more*/  ) {
        // responseElements is the one I want
        //it's an array of elements which you can filter
        var f = responseElements.filter('#myFragment');

        // do stuff with my fragment

    }
}).get('/myurl');
