Title: document.write() and alert()
Post by: Agent Moose on May 29, 2009, 08:28:09 am
document.write()
The document.write() function allowes you to write anything onto a page.

So, if I want to say Hello World, I would use this:
Code:
<script type="type/javascript">
document.write("Hello World");
</script>

You can also use HTML with it too.
Another thing you can do is call other functions or variables through a document.write() function.  here is an example of a variable being used:

Code:
<script type="type/javascript">
var text = "Hello World";
document.write(text);
</script>

You may also use HTML there.

alert()
The alert() function alowes you to create a pop-up.  So, if you wanted to create a pop-up with the text Hello World, you would do this:

Code:
<script type="type/javascript">
alert("Hello World");
</script>

You may use HTML with it.  Just like the document.write() function, you can use a variable.

Code:
<script type="type/javascript">
var text = "Hello World"
alert(text);
</script>

That would make do the same thing as the alert("Hello World").

This ones, pretty simple, but really good :)

So, if I used this, would it only show up once on the forum? Or would it come up everytime someone refreshed?
Code:
<script type="type/javascript">
alert("Welcome to Partners in Crime!");
</script>

For that you would need to use cookies. Cookies in any language can be confusing, but maybe Moose will make a tutorial about them sometime.
