set external .js parameter in the HTML page -possible

[highab]

Hello,
I want to send a parameter (string) to an external js file.

I found something very similar to what I wanted with you but it doesn't answer my question, so here goes:


I call my external js like this

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

and the diapo.js holds this

    var special="images/34b"
        var seqslides=new Array()
        seqslides[0]=[special+".jpg"]
        seqslides[1]=[special+".jpg"]
        seqslides[9]=[special+".jpg"]
        seqslides[10]=[special+".jpg"]
        seqslides[18]=[special+".jpg"]
        seqslides[19]=[special+".jpg"]         
 
 
            seqslides[2]=["images/more1.jpg"]         
            seqslides[3]=["images/longbit_gdm.jpg"] 
            seqslides[4]=["images/more2.jpg"]
            seqslides[5]=["images/longbit_programme.jpg"]
            seqslides[6]=["images/more5.jpg"]
            seqslides[7]=["images/longbit_gens.jpg"]
 

......and so on (with the code to be implemented after it ) and this works fine.

The thing is I want to be able to change my variable special depending on the page, and think I should be able to do this by putting the parameter in the HTML but haven't manage to work out how.

This doesn't work

<script type="text/javascript" src="diapo.js">special=images/newimage</script>

any help would be much appreciated!

Welcome to The Scripts.

If it's a simple variable, just declare it before you include the file:

<script type="text/javascript">
<!--
var special = "images/newimage";
//-->
</script>
<script type="text/javascript" src="diapo.js"></script>

The only problem is that you must not overwrite this variable in the js file.

thanks, that was what I wanted.
