ajax

1.

获取ajax异步请求的数据

function ajax() {
    return $.ajax(...);
}

ajax().done(function(result) {
    // code depending on result
}).fail(function() {
    // an error occurred
});
2.中断ajax请求

var xhr = $.ajax({
    type: "POST",
    url: "some.php",
    data: "name=John&location=Boston",
    success: function(msg){
       alert( "Data Saved: " + msg );
    }
});

//kill the request
xhr.abort()
