In JavaScript we can create three kinds of popup boxes: Alert box, Confirm box, and Prompt box.
Alert Box
An alert box is often used if you want to make sure information comes through to the user.
When an alert box pops up, the user will have to click "OK" to proceed.
Syntax:
Confirm Box
A confirm box is often used if you want the user to verify or accept something.
When a confirm box pops up, the user will have to click either "OK" or "Cancel" to proceed.
If the user clicks "OK", the box returns true. If the user clicks "Cancel", the box returns false.
Syntax:
Prompt Box
A prompt box is often used if you want the user to input a value before entering a page.
When a prompt box pops up, the user will have to click either "OK" or "Cancel" to proceed after entering an input value.
If the user clicks "OK" the box returns the input value. If the user clicks "Cancel" the box returns null.
Syntax:
| prompt("sometext","defaultvalue") |
Examples:
The script needs to be placed in the <head> section of your HTML document.
<script Language="JavaScript">
<!--
function popup(url, name, width, height)
{
settings=
"toolbar=yes,location=yes,directories=yes,"+
"status=no,menubar=no,scrollbars=yes,"+
"resizable=yes,width="+width+",height="+height;
MyNewWindow=window.open("http://"+url,name,settings);
}
//-->
</script> |
|
Once the script is added to your page, you can open windows using this syntax for the link tags:
<a href="#" onClick="popup('www.yahoo.com', 'Win1', 300, 300); return false">
Click Here To Go to Yahoo</a> |
