// Form the script that is to be registered at client side.
String scriptString = "<script language=JavaScript> \n";
scriptString += "function DoClick()\n {\n";
scriptString += "\t myForm.show.value='Welcome to Microsoft .NET'; \n ";

If the input is not correct, return false from the javascript function.

Right. You have to return the value in the event also:

button.Attributes["onclick"] = "return DoClick()";

Safari & Firefox go back button

Hi,
Is there a way to disable Back button for Safari? I have a submit form, let's call it "submit.aspx". Once the user clicks on "Submit" button, the information will be added into database, a confirmation email will be sent to user, then the page is redirected to confirmation page. I don't want to allow user to go back the submit page to submit for the second time. So I use history(+1) on body onload event, it works for IE. But doesn't work for Firefox and Safari.
Is there anyone having such similiar experience? How should I deal with Safari and Firefox?
Any help is appreciated!

Thanks in advance!

Disabling the Back button is a terrible idea. If and when it works, consider it a bug - no well-designed browser is likely to support it for long (if at all).
That said, there are times when you'll want to keep the user from returning to certain pages. Start by familiarizing yourself with the

<a href="http://msdn.microsoft.com/workshop/author/dhtml/reference/methods/replace.asp" rel="nofollow">location.replace()</a>

method. Then read this article on the subject:

<a onclick="window.open('KingsRdChurch.html','Kings Road Church','width=520,height=360,resizable=0,top=200,left=200,screenY=200,screenX=0');" href="javascript:void(0);"><img src="images/KingsRdChurch1.jpg" height="162" width="185" border=0 align="center">

it works fine in mozilla which is what I use. It doesnt seem to work in internet explorer. What am I doing wrong? Do I have to declare something?

Don't use spaces in the window name, e.g. 'KingsRoadChurch' instead of 'Kings Road Church'.

How to create IFRAMES in javascript?

KaKa'26-Feb-06 20:11

KaKa'

26-Feb-06 20:11

Does anybody know how to create an IFRAME so that a DIV can be placed on top of the IFRAME and SELECT?

The purpose is to allow a pop up menu not to be blocked by a windowed control e.g listbox.

I think DIV represents a windowless control like the popup menu while SELECT represents a windowed control like the listbox.

Below is a javascript file code snippet:(Contextmenu.js)

function __showContextMenu(menu)
{
var menuOffset = 55
menu.style.left = window.event.x + menuOffset;
menu.style.top = window.event.y -7;
menu.style.display = "";
window.event.cancelBubble = true;

return false;
}

function __trapESC(menu)
{
var key = window.event.keyCode;
if (key == 27)
{
menu.style.display = 'none';

}
}

There is no html because the menu is a custom control developed in C#. I have come across some IFRAME codes but they seem to be in html. How do I add IFRAME codes into this javascript file?

You can create an iframe element with:

var iframe = document.createElement('iframe');

Then you have to set all the needed properties of the element, and add the element to the page.

if you have good knowledge you can use layers to create Menu and by using javascript initially set visiblity=False and onMouseOver=visiblity=True.
for ex. in you HTML page define your Menu as:

< href="Downloads.htm">Menu-1

and your pulldown.js should be having this type of code:
-------------------------
var i=50
var c=0
var intHide
var speed=15

ns6=navigator.appName==("Netscape");

if (ns6)
{
document.getElementById('myMenu').style.visibility = "visible";
}
else
{
if (document.getElementById('myMenu'))
{
document.getElementById('myMenu').style.position = "absolute";
document.getElementById('myMenu').style.visibility = "hidden";
}

function show_hide_menu()
{

if (c==0)
{
c=1
document.getElementById('myMenu').style.visibility = "visible"
document.getElementById('myMenu').style.left = document.getElementById("IMG1").offsetParent.offsetLeft ;
document.getElementById('myMenu').style.top = document.getElementById("IMG1").offsetParent.offsetParent.offsetTop + document.getElementById("IMG1").offsetParent.offsetParent.offsetHeight ;

if(intHide !=null)
clearInterval(intHide)
intShow=setInterval("show()",50)
}
else
{
c=0
clearInterval(intShow)
intHide=setInterval("hide()",50)
}
}

function show()
{
if (i<149)
{
if (i == 0)
i = 1;
document.getElementById('myMenu').style.left = document.getElementById("IMG1").offsetParent.offsetLeft ;
document.getElementById('myMenu').style.top = document.getElementById("IMG1").offsetParent.offsetParent.offsetTop + document.getElementById("IMG1").offsetParent.offsetParent.offsetHeight ;
document.getElementById('myMenu').height = i
i=i+speed
}
}

function hide()
{
if (i>150)
{
document.getElementById('myMenu').height = i
i=i-speed
}
else
document.getElementById('myMenu').style.visibility = "hidden";
}
}

------------------------

this is just a idea you can find lots of Menu Scripts from web.

XML Parsing Problem

Hi,

I'm having trouble with parsing an XML file from Yahoo's Geocoder.

I'm getting an (0x800A01A8) Object required error on the line following line: Response.Write "Latitude" & xmlDoc.selectSingleNode("Latitude").Text

If I coment that our I get the same error on the next line.

Here is my code and the xml file I should be returning follows.

<%<br />
                        <br />
xmlURL = "http://api.local.yahoo.com/MapsService/V1/geocode?appid=SmartStart&street=3821%20Plantation%20Ln%20&zip=75035"<br />
                        <br />
'// Create the XMLHTTP object<br />
Set xmlHTTP = Server.CreateObject("MSXML2.XMLHTTP")<br />
                        <br />
'// Fire off the request!<br />
xmlHTTP.Open "GET", xmlURL<br />
xmlHTTP.Send <br />
<br />
'// Load the XML parser<br />
Set xmlDoc = Server.CreateObject("Microsoft.XMLDOM")<br />
xmlDoc.Async = False<br />
xmlDoc.loadXML (xmlHTTP.ResponseXML.xml)<br />
                            <br />
'// Set the Result node<br />
Set arrResult = xmlDoc.selectSingleNode("//ResultSet/Result")<br />
                            <br />
'// Show Latitude and Longitude<br />
Response.Write "Latitude" & arrResult.selectSingleNode("Latitude").Text<br />
Response.Write "Longitude" & ArrResult.selectSingleNode("Longitude").Text<br />
                            <br />
'// Unload XML parser<br />
Set xmlDoc = Nothing<br />
<br />
'// Destroy the object<br />
Set xmlHTTP = Nothing<br />
<br />

Either arrResult is not a valid node or "Latitude" is not a valid node.

You can print out arrResult and/or arrResult.SelectSingleNode("Latitude") and see which one is not a valid node (null node) and work from there. It might be due to missing name space?

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
