Usage

Here we have explained with a form
a) <iframe> is used to display the greybox by overlapping the form as,
<iframe frameborder=1 id='ebox1' width=100% height=100% bgcolor=#808080 style='display: none; position:absolute; top: 0px; left: 0px;filter:alpha(opacity=50);-moz-opacity: 0.5;opacity: 0.5;background-color: #808080;'>
</iframe>

Note: <iframe> should be placed at the top of the page(under <head>) to make it work in all browsers.
b) Function disp() can be called in any event.
For example,
<body onload="disp();">
<input type=button/image onClick="disp();">
c) Place your form before the div tag which displays the greybox.
d) Place your code in the div tag,
<div align=center>"Your Code Here"</div>
e) You can change the top and left position of the greybox image inorder to center align in the browser window.
var left_align = 268; // Set the left position to center the greybox
var top_align = 134; // Set the left position to center the greybox
f) mveditbox() is used inorder to have the greybox till the end of the page while scrolling.
g) Just copy the code and use it for free.
