Externalising Javascript

[Pickle]

Hello

Could anybody give me a step by step (idiots) guide on how to externalise Javascript (ie, make it like you're talking to a 10 year old.. !). I've read posts, looked at articles on the net and I don't want to bodge my site up having done that once already!

Cheers

Hi pickle right step by step

First of highlight the JavaScript code out the whole section so E.g.


<Script>

<!--

function sf(){document.f.q.focus();}

function rwt(el,ct,cd,sg){el.href="/url?sa=t&ct="+escape(ct)+"&cd="+escape(cd)+"&url=" +escape(el.href).replace(/\+/g,"%2B")+"&ei=IkXGQ-rJB8rARfOviYEI"+sg;el.onmousedown="";return true;}

// -->

</script>



then create a new file and paste it in make sure if you are using macromedia you create a new JavaScript file then paste in there take out the script tags so remove <script> </script> then save this as (whatever.js)just an example.

Then go back into your code and were the JavaScript was paste this code there

<script language="JavaScript" src="whatever.js"></script> The bit highlighted in green change to the name that you saved the JavaScript as. Then it should work.



Hope this helps

Hello

Just doing this now, seems quite straightforward but do I need to use a new file for each piece of javascript?

Also, this is an example of some script:
<script language="JavaScript" type="text/JavaScript">
<!--
function MM_reloadPage(init) { //reloads the window if Nav4 resized
if (init==true) with (navigator) {if ((appName=="Netscape")&&(parseInt(appVersion)==4)) {
document.MM_pgW=innerWidth; document.MM_pgH=innerHeight; onresize=MM_reloadPage; }}
else if (innerWidth!=document.MM_pgW || innerHeight!=document.MM_pgH) location.reload();
}
MM_reloadPage(true);
function MM_preloadImages() { //v3.0
var d=document; if(d.images){ if(!d.MM_p) d.MM_p=new Array();
var i,j=d.MM_p.length,a=MM_preloadImages.arguments; for(i=0; i<a.length; i++)
if (a[i].indexOf("#")!=0){ d.MM_p[j]=new Image; d.MM_p[j++].src=a[i];}}
}
function MM_swapImgRestore() { //v3.0
var i,x,a=document.MM_sr; for(i=0;a&&i<a.length&&(x=a[i])&&x.oSrc;i++) x.src=x.oSrc;
}
function MM_findObj(n, d) { //v4.01
var p,i,x; if(!d) d=document; if((p=n.indexOf("?"))>0&&parent.frames.length) {
d=parent.frames[n.substring(p+1)].document; n=n.substring(0,p);}
if(!(x=d[n])&&d.all) x=d.all[n]; for (i=0;!x&&i<d.forms.length;i++) x=d.forms[i][n];
for(i=0;!x&&d.layers&&i<d.layers.length;i++) x=MM_findObj(n,d.layers[i].document);
if(!x && d.getElementById) x=d.getElementById(n); return x;
}
function MM_swapImage() { //v3.0
var i,j=0,x,a=MM_swapImage.arguments; document.MM_sr=new Array; for(i=0;i<(a.length-2);i+=3)
if ((x=MM_findObj(a[i]))!=null){document.MM_sr[j++]=x; if(!x.oSrc) x.oSrc=x.src; x.src=a[i+2];}
}
//-->
</script>

when I paste this into the script.js file (or whatever I call it) do I delete the line <script language="JavaScript" type="text/JavaScript"> and then </script>?

Many thanks

yes, u do delete those lines, and you can put as much javascript as u like in one file

Hi is this the same for externalising php code as well.
(ive got an invisible php counter but i don't want to change the page to .php just for this tiny code thats about 4 lines long)
