推荐答案

一旦iframe加载完毕，您就必须使用contents()获取内容，然后搜索并获取锚点的href属性，并且加载的内容不能跨域，具有相同的来源策略等:

Once the iframe has loaded, you'll have to use contents() to get the content, and then search and get the href property of the anchor, and the loaded content can't be cross domain, same origin policy etc :

$(document).ready(function() {
    $('#test').on('load', function() {
        var value = $(this).contents().find("#division a").prop('href');
        alert(value);
    });
});
