在WebForm_OnSubmit之后调用自定义客户端验证功能吗? .网 [英] Call custom client side validation function after WebForm_OnSubmit? .NET

问题描述

.NET验证程序控件运行其javascript后，我想运行一个简单的JS函数. 我的onsubmit值是javascript:return WebForm_OnSubmit();，它似乎是自动生成的，我无法更改.

I want to run a simple JS function after my .NET validator controls run their javascript. My onsubmit value is javascript:return WebForm_OnSubmit();, which seems to be generated automatically and I can't change it.

我是正确的假设我需要在此字段中添加一个函数以使其正常工作吗?另外，我的表单正在更改字段后进行验证(不是一旦提交表单就进行验证)，这很好，但是是否有设置soimewhere来启用/禁用该功能?

Am I right in assuming I need to just add a function in this field to get it to work? Also, my form is validating after a field has been changed (not once the form has been submitted), which is great, but is there a setting soimewhere to turn that on/off?

谢谢！

推荐答案

虽然我将为以后发布一个较晚的答案.
如果您的aspx页面是简单页面(没有ContentPage，所以没有MasterPage)，则可以直接在标记上添加onsubmit函数:

Althought it is a late answer I will post for future.
If your aspx page is a simple page (no ContentPage, so no MasterPage) you can add onsubmit function directly on the markup:

<form ... onsubmit="return myCustomValidation();"... >

"WebForm_OnSubmit()"将首先执行，然后如果验证通过，将执行"myCustomValidation()".

"WebForm_OnSubmit()" will be executed first and then if validation is ok "myCustomValidation()" will be executed.

如果您的aspx页面是ContentPage(因此具有MasterPage)，则您无权访问标记以执行与以前相同的操作.您可以在后面的代码中将"myCustomValidation()"设置为在"WebForm_OnSubmit()"之后执行:

If your aspx page is a ContentPage (so it has a MasterPage) you don't have access to markup in order to do the same as before. You can set "myCustomValidation()" to be executed after "WebForm_OnSubmit()" in code behind:

Private Sub Page_PreRenderComplete(sender As Object, e As EventArgs) Handles Me.PreRenderComplete
    If Not Page.ClientScript.IsOnSubmitStatementRegistered(Me.GetType, "aspxMyCustomValidation") Then
        Page.ClientScript.RegisterOnSubmitStatement(Me.GetType, "aspxMyCustomValidation", "myCustomValidation()")
    End If
End Sub

关键是在"PreRenderComplete"事件中而不是在"Load"事件中设置此代码，以便在"WebForm_OnSubmit()"之后执行"myCustomValidation()".

The key is to set this code in "PreRenderComplete" event and not in "Load" event, in order to execute "myCustomValidation()" after "WebForm_OnSubmit()".
