Question

在我的项目中，我有（以及其他）2 ascx个文件。每个人都有一个可编辑的网格。但是当我在UsersGrid.ascx文件的网格中编辑一个单元格时，它会调用TrialDashboard.ascx文件的直接方法。如果我发出一个带有此错误的alert（），问题就解决了：

参数列表
之后的
Uncaught SyntaxError：missing）

在调用其直接方法之前，在TrialDashboard.ascx的edit（）js函数中

。这是代码：

UsersGrid.ascx

<ext:XScript ID="XScript1" runat="server">
    <script type="text/javascript">
        var edit = function (editor, e) {
            if (!(e.value === e.originalValue)) //|| (Ext.isDate(e.value) && Ext.Date.isEqual(e.value, e.originalValue)))) {
               #{DirectMethods}.UpdateRow(e.record.data.UserId, e.field, e.originalValue, e.value);

        };

        var Before = function (item,e) {
            //alert('e.record.data.UserId:'+e.record.data.UserId+'e.field:'+e.field+'e.originalValue:'+e.originalValue+'e.value:'+e.value);

edit函数定义了两次。即使它们位于单独的ascx文件中，如果名称在使用自定义控件的页面上不唯一，则会覆盖另一个。您可以尝试将它们重命名为UsersGrid_edit和TrialDashboard_edit，或使用其他命名约定来确保名称唯一。

C＃EXT（奇怪的行为）：ascx调用另一个ascx的directmethod
