Question

我的代码： 自定义验证功能错误请帮助＆gt;＆gt;＆gt;＆gt;

自定义验证函数无法返回值，json函数仍然有效，但无法返回值

<script type="text/javascript">

    $(document).ready(function () {

$.getJSON("/ChequeBookReceipt/getChequeType/", function (data) {
            setupGrid(data.item);
        });





        function reload(result) {
            $("#listChequeBook").trigger("reloadGrid");
        }
    });



    function setupGrid(data) {
        var success = false;
        var message = 'success';
        var item = data;
