Microsoft JScript运行时错误：无法获取属性“length”的值：object为null或undefined [英] Microsoft JScript runtime error: Unable to get value of the property 'length': object is null or undefined

问题描述

大家好，



我已按照以下方式对所需的档案使用ajax错误控制 -

Hi All,

I have use ajax error control for required filed in following way -

<asp:UpdatePanel ID="dateUpdatePanel" runat="server">
                             <ContentTemplate>
                               <asp:TextBox ID="txtCreatedDate" runat="server" CssClass="txt" ></asp:TextBox>
                            </ContentTemplate>
                               </asp:UpdatePanel>
                           <asp:RequiredFieldValidator ID="rfvCreatedDate" runat="server" ErrorMessage="Required field"

                               Display="None" ControlToValidate="txtCreatedDate" />
                           <AjaxTK:ValidatorCalloutExtender ID="vceCreatedDate" TargetControlID="rfvCreatedDate"

                               runat="server" />

但是当我点击jqurey日历控件时它会给出以下错误



Microsoft JScript运行时错误：无法获取属性的值'' length''：对象为null或未定义



i有google搜索并获得了许多解决方案，但它不起作用，仍然会出现同样的错误。

but when i am click on jqurey calendar control its give following error

Microsoft JScript runtime error: Unable to get value of the property ''length'': object is null or undefined

i have googled and got many solution but its not working, still its give same error.

推荐答案

相同错误： - Microsoft JScript运行时错误：无法获取属性''click''的值：object为null或undefined
