Page.RegisterOnSubmitStatement Method

NOTE: This method is now obsolete.

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

	script : String
)
Not applicable.

Parameters

key

Unique key that identifies a script block.

script

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.

Security noteSecurity 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 (Visual Studio).

void Page_Load(Object sender, EventArgs e) 
{ 
   String scriptString = "<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);
} 

void Page_Load(Object sender, EventArgs e) 
{ 
    String scriptString 
= "<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);
