How can I pass an array of URLs consecutively to $.Ajax URL?

Question

var a;
var urlArray = [];

$("a").each{function(){ 
    a = $(this).attr("href"); 
    urlArray.push(a);
});

var sArray = [];

$.each(urlArray, function(x, y){
         $.ajax({
               url: y, // pass the URLs consecutively
               type: 'get',
               dataType: 'html',
               success: function(data){
                   sArray.push( $("video").attr("src") );
                }
         })
});

log(sArray); // returns a single URL, not array as expected

I've been attempting to retrieve src values of <video> elements via $.Ajax calls. I try and pass an array of URLs consecutively to $.Ajax via $.each, but results logged from success: only come from a single URL. I expect an array returned, but am only able to .push one value into sArray.

Can someone explain how I can manage to consecutively retrieve the data I need from each URL sent to $.Ajax? Thank you.

Note: Put simply, I need to pass an array of URLs to $.Ajax so that I can retrieve data from every one of those URLs.
