[SOLVED]Help with jquery selection

Hi I try to write a simple script to alert the href of an link on a page. The Link is frequently changed manually.
Can anybody help me to get the URL of the link with text 'Wochenfahrplan GAR-WZW
für Woche 26.09. - 30.09.2016' on http://www.sf-biowiss.wzw.tum.de/index.php?id=258 please

Thanks for any help...

EDIT:
I tried this:
(function() {
var x = $("#c782").find("a.download:first");
alert(x);
})();
