guardate questo script (da vs net)
con Response.write("-------" & showMessage1.innerHTML) verifico il testo .. ed effettivamente il testo di showMessage1 è vuoto..codice:<html> <head> <script language="VB" runat="server"> public Sub Page_Load(Sender As Object,e As EventArgs) ' Form the script to be registered at client side. Dim scriptString As String = "<script language=JavaScript> function DoClick() {" scriptString += "showMessage2.innerHTML='<h4>Welcome to Microsoft .NET!</h4>'}" scriptString += "function PageLoad(){ showMessage1.innerHTML=" scriptString += "'<h4>RegisterStartupScript Example</h4>'}<" scriptString += "/" scriptString += "script>" If(Not Me.IsStartupScriptRegistered("Startup")) Then Me.RegisterStartupScript("Startup", scriptString) End If Response.write("-------" & showMessage1.innerHTML) End Sub </script> </head> <body topmargin="20" leftmargin="10" onLoad="PageLoad()"> <form id="myForm" runat="server"> <span id="showMessage1" runat="server"></span> <input type="button" value="ClickMe" onclick="DoClick()"> <span id="showMessage2"></span> </form> </body> </html>
invece io voglio ke ciò nn accada .. ciò ke prima del page_load ci sia lo script js .. come faccio?
