JQuery AJAX的嵌套使用

　　<script type="text/javascript">
        $(function () {

            $.post("Ajax/HideHandler.ashx", { type: "getData" }, function (data) {
                
                if (data != null && data != "undefined" && data != "") {
                    for (var i = 0; i < data.length; i++) {
                        var detailItem= MatchUrl(data[i]);             
                        $("#detailItem").append(detailItem);
                    }
                }
                else {
                    var detailItem= "No data";
                    $("#detailItem").append(detailItem);
                }
            }, "json");

        function MatchUrl(data) {
            var returnhtml = "";
            //同步的AJAX调用才有返回值
            var id = $.ajax({ url: "Ajax/JudgeHandler.ashx", type: ‘POST‘,async:false,cache:false, data: "action=1&id=" + data.ID, }).responseText;
            
            if (id == 0) {
                returnhtml = "item为 0";
            } else {
                returnhtml = id;
            }
            return returnhtml;
        }
    </script>
