嗨我在我的脚本中有2个ajax调用,我需要它们运行asnyc来腾出时间,但我需要第二个等到第一个完成.

$.ajax({
        type: "POST",
        url: "getText.asmx/ws_getText",
        data: parO1,
        contentType: "application/json; charset=utf-8",
        dataType: "json",
        success: function (msg) {
            alert(msg.d.data);
        }
        , error: function () {
            chyba("chyba v požadavku", "df");
        }
    });
    if (parO2.length > 0) {
        $.ajax({
            type: "POST",
            url: "getText.asmx/ws_getText",
            data: parO2,
            contentType: "application/json; charset=utf-8",
            dataType: "json",
            success: function (msg) {
                /*WAIT UNTIL THE FIRST CALL IS FINISHED AND THAN DO SOMETHING*/
            }
        , error: function () {
            chyba("chyba v požadavku", "df");
        }
        });

那么任何想法？谢谢
