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);
} //Page_Load
