Page.RegisterOnSubmitStatement Method (String, String)

 
Note: This API is now obsolete.

Allows a page to access the client OnSubmit event. The script should be a function call to client code registered elsewhere.

Namespace:   System.Web.UI
Assembly:  System.Web (in System.Web.dll)

<ObsoleteAttribute("The recommended alternative is ClientScript.RegisterOnSubmitStatement(Type type, string key, string script). http://go.microsoft.com/fwlink/?linkid=14202")>
Public Sub RegisterOnSubmitStatement (
	key As String,
	script As String
)

Parameters

key
Type: System.String

Unique key that identifies a script block.

script
Type: System.String

The client-side script to be sent to the client.

The RegisterOnSubmitStatement method has been deprecated. Use the RegisterOnSubmitStatement method in the ClientScriptManager class.

The following code example demonstrates using the RegisterOnSubmitStatement to access a script that responds when a client-side Submit button is clicked. When this event occurs, the registered ECMAScript code is executed on the client.

System_CAPS_security Security Note

This example has a hidden field, which is a potential security threat. By default, you should validate the value of a hidden field as you would the value of a text box. ASP.NET Web pages validate that user input does not include script or HTML elements. For more information, see Script Exploits Overview.


     Dim scriptString As String = "<script language=""JavaScript""> function doClick() {"
scriptString += "document.write('<h4>' + myForm.myHiddenField.value+ '</h4>');}<"
scriptString += "/" + "script>"

RegisterHiddenField("myHiddenField", "Welcome to Microsoft!")

RegisterOnSubmitStatement("submit", "document.write('<h4>Submit button clicked.</h4>')")

RegisterStartupScript("startup", scriptString)
