jquery - 提交表单后未打开正确的手风琴菜单

Question

我有 $("#accordId").val() from servlet ，这是表单提交之前的手风琴 ID，我想打开同一个手风琴。

$(document).ready(function() {
        aId = $("#accordId").val();
        alert(aId);
        if(aId =="")
            aId = 0;
        $("#accordionCategory").accordion({
            collapsible  : true,
            active       : false,
            heightStyle  : "content",
            navigation   : true,
            active: aId
        });

});

警报给出了正确的结果，但没有打开正确的accordin菜单，请帮助
