测试 var getToken = function(callback, token) { $.ajax({ onsuccess: function(data) { callback(data.id, token); } }); };

var token = 1; var isLoading = false;

var requestList = function() { if (isLoading) { return null; } isLoading = true; token++;

function onsuccess(id, requestToken) {
    $.ajax({
        data: {
            id: id
        },
        onsuccess: function(string) {
            if (requestToken == token) {
                renderList(string);
            }
