clientscript.RegisterStartupScript

[hpl]

In asp.net 1.1 I had no problems using this:
Page.RegisterStartupScript("ClientScript", strScript)

But as I moved to asp.net 2.0 I receive an error, it recommends me to use
ClientScript.RegisterStartupScript instead. Which arguments do I need to execute the same as in 1.1?

Did not get to .net 2 yet, but try Response.Write(myscript)

Although I see no documentation on it, I'd assume it's the same as Page.RegisterStartupScript().

Response.Write isn't a good idea in most cases...

I can swear it was you that recommended that to me....*scratching head*

You need to use ClientScriptManager.RegisterStartupScript, Page.RegisterStartupScript has been removed from .NET 2.0.

[hpl]

ok, but I can't type ClientScriptManager.RegisterStartupScript("ClientScript", strScript), what kind of arguments does this require?

[Shuja Ali]

You don't have to use ClientScriptManager, that was a Typo

Anyways here is an example

ClientScript.RegisterStartupScript(Me.GetType(), "ClientScript", "alert ('hello')", True)

[hpl]

Great, I will try that, thanks

I was the one who was totally against it. I must've given so many lectures on it that subject that you associated it with me.

Now I've tried the code
ClientScript.RegisterStartupScript(Me.GetType(), "ClientScript", "alert ('hello')", True)
but now it says

Error	442	Name 'ClientScript' is not declared.	e:\Visual Studio 2005\WebSites\GF\Pressure1Abs.ascx.vb	383	9	e:\...\GF\

[Shuja Ali]

Use

Page.ClientScript.RegisterStartupScript(Me.GetType(), "ClientScript", "alert ('hello')", True)

[hpl]

It doesn't work, nothing happens when I execute that code??? Does it work for you? I am using a beta of IE7, could it be that?

[hpl]

It doesn't work, because a ";" is missing after the JS-code. Now it works ;-). Thanks

[xhinodread]

Thank men

ClientScript.RegisterStartupScript(Me.GetType(), "ClientScript", "alert ('hello')", True)

Work...

yea

[dclonch1]

ScriptManager.RegisterStartupScript(Me, Page.GetType, "scriptkey", "yourScript();", True)

Use it all the time, just make sure you have a script manager on the page above it.

Hi -- My question is related to this thread. I'm using clientscript.RegisterStartupScript in a child page to register a script and have it execute after the page loads. The code is as follows
ClientScript.RegisterStartupScript(GetType(Page), "", "OnInitial();", True)

THe script OnInitial() is contained in an external file and it looks like this:

var nSubtopics;
var nTopics;
var aTopicText;
var aTopicValue;
var aSubtopicText;
var aSubtopicValue;
var nSelectedTopic;
var nSelectedSubtopic;
function OnInitial()
{
//debugger;;
var i, j, n, strTopic, strSubtopic;

nTopics =document.getElementById("_ctl0_ContentPlaceHolder1_ddlTopic").options.length;
aTopicText = new Array(nTopics);
aTopicValue = new Array(nTopics);
for (i=0; i< nTopics; i++)
{
aTopicText[i] = document.getElementById("_ctl0_ContentPlaceHolder1_ddlTopic").options[i].text;
aTopicValue[i] = document.getElementById("_ctl0_ContentPlaceHolder1_ddlTopic").options[i].value;
}
nSubtopics = document.getElementById("_ctl0_ContentPlaceHolder1_ddlSubtopic").options.length;
aSubtopicText = new Array(nSubtopics);
aSubtopicValue = new Array(nSubtopics);
for (i = 0; i < nSubtopics; i++) {
aSubtopicText[i] = document.getElementById("_ctl0_ContentPlaceHolder1_ddlSubtopic").options[i].text;
aSubtopicValue[i] = document.getElementById("_ctl0_ContentPlaceHolder1_ddlSubtopic").options[i].value;
}
nSelectedTopic = document.getElementById("_ctl0_ContentPlaceHolder1_ddlTopic").selectedIndex;
nSelectedSubtopic = document.getElementById("_ctl0_ContentPlaceHolder1_ddlSubtopic").selectedIndex;
if (nSelectedTopic == 0) {
document.getElementById("_ctl0_ContentPlaceHolder1_ddlSubtopic").options.length = 1;
}
else {
strTopic = document.getElementById("_ctl0_ContentPlaceHolder1_ddlTopic").options[nSelectedTopic].text;
n = strTopic.length;
j = 0;
for (i = 1; i < nSubtopics; i++) {
strSubtopic = aSubtopicValue[i];
if (strTopic != strSubtopic.substring(0, n))
{
document.getElementById("_ctl0_ContentPlaceHolder1_ddlSubtopic").options[i - j] = null;
j++;
}
}
}
}

function OnChangeTopic()
{ var i, j, n, strTopic, strSubtopic,strSubtopicVal;

if (nSelectedTopic != document.getElementById("_ctl0_ContentPlaceHolder1_ddlTopic").selectedIndex)
{


nSelectedTopic = document.getElementById("_ctl0_ContentPlaceHolder1_ddlTopic").selectedIndex;
strTopic = document.getElementById("_ctl0_ContentPlaceHolder1_ddlTopic")[nSelectedTopic].text;

document.getElementById("_ctl0_ContentPlaceHolder1_ddlSubtopic").options.length = 1;
if (nSelectedTopic != 0)
{
j = 1;
n = strTopic.length;
for (i = 1; i < nSubtopics; i++)
{
//strSubtopic = aSubtopicValue[i];
strSubtopic = aSubtopicText[i];
strSubtopicVal = aSubtopicValue[i];
if (strTopic == strSubtopic.substring(0, n))
{
document.getElementById("_ctl0_ContentPlaceHolder1_ddlSubtopic").options[j] = new Option(strSubtopic.substring(n + 1, strSubtopic.length), strSubtopicVal);
if (nSelectedSubtopic == i) {
document.getElementById("_ctl0_ContentPlaceHolder1_ddlSubtopic").selectedIndex = j;
}
j++;
}
}
}
}
}
function OnChangeSubtopic()
{ var i, n, strSubtopic;
n = document.getElementById("_ctl0_ContentPlaceHolder1_ddlSubtopic").selectedIndex;
if (n == 0)
{
nSelectedSubtopic = 0;
}
else
{
strSubtopic = document.getElementById("_ctl0_ContentPlaceHolder1_ddlSubtopic")[n].value;
for (i = 1; i < nSubtopics; i++)
{
if (strSubtopic == aSubtopicValue[i])
{
nSelectedSubtopic = i;
break;
}
}
}
}

<!--
function MM_reloadPage(init) { //reloads the window if Nav4 resized
if (init==true) with (navigator) {if ((appName=="Netscape")&&(parseInt(appVersion)==4)) {
document.MM_pgW=innerWidth; document.MM_pgH=innerHeight; onresize=MM_reloadPage; }}
else if (innerWidth!=document.MM_pgW || innerHeight!=document.MM_pgH) location.reload();
}
MM_reloadPage(true);
//-->


In IE7 this works OK. In IE8/FIreFox it does not work. It t cannot find the script. I get an "Object Expected" error.

Any help would be appriciated.

Hello jliotine,

Welcome to the forums!!

A couple of points I think that need to be made.

First of all, when posting into the forum, can you remember to surround your code in [CODE][/CODE] tags, it makes it so much easier to read.

Secondly, reviving a thread that is almost two years old doesn't really make much sense, it might have been better to start your own thread.

So to save me digging through the JavaScript, can you give a brief description of what your function does? Do you know at which point the JavaScript is failing? Have you tried debugging your JavaScript to try and isolate where the problem is?

Gary
