使用RequiredFieldValidator时，jQuery方法无法从代码后面触发

Question

I'm having a problem with a jQuery method being called from code behind when using a RequiredFieldValidator. This works great without the RequiredFieldValidator on the form. When it's on the form, I get an error:

Microsoft JScript runtime error: Object doesn't support property or method 'toastmessage'

as if it hasn't loaded the jquery.js file.

As a test, I have a simple page that has a TextBox on it and a button within an UpdatePanel. When you click the button, it fires the server side OnClick method with the following code:

        ScriptManager.RegisterClientScriptBlock(this.Page, this.Page.GetType(), "alert", @"$().toastmessage('showWarningToast', 'Record Saved Successfully.'); ", true);

This works great, and pops the message. When I attach a RequiredFieldValidator to the TextBox is when the error pops up. Does anyone have any ideas what might be causing this?

将此添加到您的必填字段验证器中：

EnableClientScript="false"
