JavaScript .class Extraction

JavaScript .class Extraction

I am writing JavaScript that retrieves a webpage from another site, and
only displays 'Notices' from a site.
Fortunately, all 'Notices' are div elements of class 'event'.
I want to extract only these divs from the returned code so that I can
re-format and display them. All the code I have so far is working, but I'm
not sure on how to extract the 'event' divs from the source code. Any
ideas?
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)
});
}
Thanks guys!
