JavaScript <div> .class 提取

Question

我正在编写 JavaScript，用于从另一个站点检索网页，并且仅显示来自站点的“通知”。
幸运的是，所有“通知”都是“事件”类的 div 元素。
我只想从返回的代码中提取这些 div，以便我可以重新格式化并显示它们。到目前为止，我拥有的所有代码都可以正常工作，但我不确定如何从源代码中提取“事件”div。有什么想法吗？

function getNotices(){
    // Get the date from the form
    var str = document.getElementById('formDate').value; 
    var year = str.slice(1,4); // Extract Year
    var month = str.slice(6,7); // Extract Month
    var day = str.slice(9,10); // Extract Day

    // Inject correct date into URL
    var link = "<a href=\"http://ilearn.stpauls.school.nz/calendar/view.php?view=day&course=1&cal_d=" + day + "&cal_m=" + month + "&cal_y=" + year + "\">Raw Link</a>";
    // Write raw link to div for debugging
    document.getElementById('rawLink').innerHTML = link;  (debugging)

    // Bounce off anyorigin.com to get the source
    // Re-inject date into new link
    var anyLink = "http://anyorigin.com/get?url=http%3A//ilearn.stpauls.school.nz/calendar/view.php%3Fview%3Dday%26course%3D%26cal_d%3D" + day + "%26cal_m%3D" + month + "%26cal_y%3D" + year + "&callback=?"; // Splice the date into the school link and site to bounce it off
    $.getJSON('http://anyorigin.com/get?url=http%3A//ilearn.stpauls.school.nz/calendar/view.php%3Fview%3Dday%26course%3D1%26cal_d%3D30%26cal_m%3D7%26cal_y%3D2013&callback=?', function(data){
        var obj = JSON.stringify(data); // Turn object into a string
        document.getElementById('hopefullyTheData').innerHTML = obj; // Print string containing SPC website onto page (debugging)
    });
}

谢谢大家!

将内容加载到 jQuery 中，然后按事件类选择:

var events = $(data.contents).find('.event');
