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)
