How can I call this javascript, externally? (Random-Order content script)

Step 1

<script>

/*
Random-Order content script
By JavaScript Kit (http://www.javascriptkit.com)
This notice must stay intact for use
*/

//1) Specify content(s) to display and rotate
// You can specify multiple "sets", each displayed in diff. areas of your page

var content=new Array() //sample set 1
content[0]='<a href="http://www.dynamicdrive.com"><img src="http://www.javascriptkit.com/dynamic.gif" border=0></a>'
content[1]='<a href="http://cooltext.com"><img src="http://www.cooltext.com/images/ctb4.gif" border=0></a>'
content[2]='<a href="http://thefreesite.com"><img src="http://www.thefreesite.com/free88.gif" border=0></a>'

var diffcontent=new Array() //sample set 2
diffcontent[0]='<a href="http://www.google.com">Google Search Engine</a>'
diffcontent[1]='<a href="http://news.bbc.co.uk">BBC News</a>'
diffcontent[2]='<a href="http://www.msnbc.com">MSNBC News</a>'


function randomorder(targetarray, spacing){

var randomorder=new Array()
var the_one
var z=0
for (i=0;i<targetarray.length;i++)
randomorder[i]=i

while (z<targetarray.length){
the_one=Math.floor(Math.random()*targetarray.length)
if (targetarray[the_one]!="_selected!"){
document.write(targetarray[the_one]+spacing)
targetarray[the_one]="_selected!"
z++
}
}
}

</script>

step 2

<script>
//2) Call function randomorder(arrayname, space_between_content)
randomorder(content, '<br><br>')
randomorder(diffcontent, '<br>')
</script>


Ok... I know that in order to call this from a external file you take... step 1, and remove the end tags, then save n' name it to a .js file. Thats the easy part... but how do I call the .js if theres step's 2 coding left... like this?

<script src="name_of_file.js">
randomorder(content, '<br><br>')
randomorder(diffcontent, '<br>')
</script>

usually all you have to do is this...

<script src="name_of_file.js"></script>

and your fine, but the remaining code...

randomorder(content, '<br><br>')
randomorder(diffcontent, '<br>')

keeps me from doing so...Any idea's how to call it?

Did you try placing the script itself in an external file and leave those step two's alone???

You could place them both in the same script file like so:
/*
Random-Order content script
By JavaScript Kit (http://www.javascriptkit.com)
This notice must stay intact for use
*/

//1) Specify content(s) to display and rotate
// You can specify multiple "sets", each displayed in diff. areas of your page

var content=new Array() //sample set 1
content[0]='<a href="http://www.dynamicdrive.com"><img src="http://www.javascriptkit.com/dynamic.gif" border=0></a>'
content[1]='<a href="http://cooltext.com"><img src="http://www.cooltext.com/images/ctb4.gif" border=0></a>'
content[2]='<a href="http://thefreesite.com"><img src="http://www.thefreesite.com/free88.gif" border=0></a>'

var diffcontent=new Array() //sample set 2
diffcontent[0]='<a href="http://www.google.com">Google Search Engine</a>'
diffcontent[1]='<a href="http://news.bbc.co.uk">BBC News</a>'
diffcontent[2]='<a href="http://www.msnbc.com">MSNBC News</a>'


function randomorder(targetarray, spacing){

var randomorder=new Array()
var the_one
var z=0
for (i=0;i<targetarray.length;i++)
randomorder[i]=i

while (z<targetarray.length){
the_one=Math.floor(Math.random()*targetarray.length)
if (targetarray[the_one]!="_selected!"){
document.write(targetarray[the_one]+spacing)
targetarray[the_one]="_selected!"
z++
}
}
}
randomorder(content, '<br><br>')
randomorder(diffcontent, '<br>')

Then just refer to it this way:
<script type="javascript/text" src="name_of_file.js"></script>

Thanks requestcode,

but that didn't work...calling the file by using:

<script type="javascript/text" src="name_of_file.js"></script>

but, I got it to work by removing the:

type="javascript/text"

and called it using:

<script src="name_of_file.js"></script>

Heh. He got it the wrong way- it should be 'text/javascript'. Oh, and the type attribute is required, so don't remove it, just correct it.

I know I am late to the party on this one. I have the script to work fine in mozilla. I keep getting an error as undefined in IE. Help is greatly appreciated, as I cannot seem to figure it out.

I should add error seems to come at randomorder(diffcontent, '<br>')
I don't why. I have tried everything.

Figured it out...please disregard me...
make sure you are careful if you decide to go with images or text only.
