推荐答案

txtDoJ的"OnTextChanged事件"中的Java脚本函数，

您需要从服务器端添加的属性.
试试:

java script function in txtDoJ''s "OnTextChanged Event ",

You need to add an attribute of client side onchange from server side.
Try:

txtDOJ.Attributes.Add("onchange","javascript:MyJSMethodWhereINeedToChange()");

这样做会引入文本更改的客户端事件.

或

或者，您可以使用 HTML输入控件.这样，直接在html设计器中使用onchange会触发JS事件.为了触发服务器textchange事件，您需要使用onserverchange事件.

Doing this would introduce the client side event of text change.

OR

Alternatively, you can use the HTML input control. In that, directly onchange in html designer would trigger the JS event. In order to trigger server textchange event, you would need to use onserverchange event.

在onchange事件上调用JavaScript.

Call your javascript on onchange event.

<asp:TextBox ID="txtDOJ" runat="server" onchange="javascript:alert(''test'');"></asp:TextBox>

如果要比较两个具有日期时间值的文本框，我建议您使用Type ="Date"

If you want to compare two text boxes having date time values, I would recommend you should use a compare validator with Type="Date"

的比较验证器.
