JavaScript Problem with document.write()

1 New Member

Hi I am sunny and a started working on JavaScript recently.
I am stuck up in one script.

The Script goes on like this

[HTML]<HTML>
<HEAD>
<Script Language = "JavaScript">
function call()
{
var str = prompt("Welcome Your name is", "")
document.write(str)
}
</Script>
</HEAD>
<Body bg color=gray>
<Form name="test">
<Input type="Button" name="b1" value="submit" onClick="call()">
</Form>
</Body>
</HTML>
[/HTML]
My Question is
Why does the background color goes off when the "document.write" cmd executes.

Please guide me thru.

document.write will write to the object from within it is called, for example if it was inside a div it will write to that div erasin everythin inside the div.

so whats happening here is your calling document.write from within the head. I guess it is erasing everything in the document and writing your string to the empty document.

yes ... thats the point ... you may use innerHtml or proper dom-node-handling for that purpose ... you should never use document.write when a page is loaded already ....

kind regards

ps: changed thread-title to better describe the problem ...
