找出下列代码的错误点 var store = me.Store_BPMDATA_AdmissionFee_M; var ids=[]; var grid = me.Grid_BPMDATA_AdmissionFee_M; var recs = grid.getSelectionModel().getSelection(); debugger; Ext.Msg.show( { title: '同步数据', //msg: '您确定要删除选中项吗？', buttons: Ext.Msg.OK, //buttons: Ext.Msg.OKCANCEL, defaultFocus: 'OK', //defaultFocus: 'cancel', //icon: Ext.MessageBox.INFO, fn: function (btn, text) { YZSoft.Ajax.request( { url: YZSoft.$url(me, 'YZModules/RenewalPayment.ashx'), method: 'POST', params: { method: 'ProcessRequest' }, jsonData: , success: function (action) { var rv = ""; debugger; store.reload(); }, failure: function (action) { var rv = action.result.errorMessage; Ext.Msg.alert("提示", "通知操作失败，请联系管理员！" + rv) } }); } });

代码中有一个语法错误，即 `jsonData: ,` 这一行。应该在 `jsonData:` 后面加上一个空对象 `{}`，表示传递一个空的 JSON 对象。修改后的代码如下：

var store = me.Store_BPMDATA_AdmissionFee_M;
var ids=[];
var grid = me.Grid_BPMDATA_AdmissionFee_M;
var recs = grid.getSelectionModel().getSelection();
debugger;
Ext.Msg.show({
    title: '同步数据',
    //msg: '您确定要删除选中项吗？',
    buttons: Ext.Msg.OK,
    //buttons: Ext.Msg.OKCANCEL,
    defaultFocus: 'OK',
    //defaultFocus: 'cancel',
    //icon: Ext.MessageBox.INFO,
    fn: function (btn, text) {
        YZSoft.Ajax.request({
            url: YZSoft.$url(me, 'YZModules/RenewalPayment.ashx'),
            method: 'POST',
            params: {
                method: 'ProcessRequest'
            },
            jsonData: {}, // 修复语法错误
            success: function (action) {
                var rv = "";
                debugger;
                store.reload();
            },
            failure: function (action) {
                var rv = action.result.errorMessage;
                Ext.Msg.alert("提示", "通知操作失败，请联系管理员！" + rv)
            }
        });
    }
});
