Howto Cut a URL string in an array? 1

RedLion · Nov 1, 2000

Hello,

I've got the URL: preview.html?name=Mr.%20Smit&Adres=Firststreet%205
now the page has to be look like:

Name: Mr. Smit
Adres: Firststreet 5

Now the problem, how to do that?

<html>
<body>
Name:
<SCRIPT LANGUAGE=javascript>
var s = document.location.search;
s = s.replace(/\?name=/, "&quot

;
s = s.replace(/%20/g, " &quot

;
s.split("\&&quot

;
s[1] = s[1].replace(/adres/, "&quot

;
document.write(s[0]);
document.write("<BR>" + "Adres:" + s[1])
//-->
</SCRIPT>
</BODY>
</HTML>

It's nice, but it doesn't work. So please help?

Thanks Charl

you want to use window.location.search; this will return a string that looks like this:

string looks like: ?name=snarf&pants=red&weight=50

then just split the string on "&" and you will receive the following strings in the splitstring array:

?name=snarf :use replace to kill the "?" and split "="
pants=red :split on "="
weight=50 :split on "="

I have a library for handling this, if you want to use/see it...

Dear Charl,

Here is a javascript object that will handle the querystring for you:

/*
javascript class declaration QueryString
This version does not support arrays of variables, however could
be modified to support arrays.

Copyright (c) Saber Consulting 1999, All Rights Reserved World Wide

*/
function JQueryString(){

this.values = new Array();
this.names = new Array();

this.qs = unescape(document.location.search);
this.qs = this.qs.substr(1);
this.values = this.qs.split("&&quot

;
for(nqs=0; nqs<this.values.length; nqs++){

var a = this.values[nqs].split("=&quot

;
this.names[nqs] = a[0].toLowerCase();
}

this.get = jqs_get;

function jqs_get( varName){

if ( 'undefined' == typeof(varName)) varName = new String("&quot

;
varName = varName.toLowerCase();

var nIndex = -1;
for(n=0; n<this.names.length && -1 == nIndex; n++){
// if they match set nIndex
if ( this.names[n].indexOf(varName) == 0 &&
this.names[n].length == varName.length) {
nIndex = n;
}
} // for())

// if found... split out the value and return it
if ( nIndex > -1){
var a = this.values[nIndex].split("=&quot

;
return new String(a[1]);
}

return "";
}
} // JQueryString

You would use it like so...

<SCRIPT LANGUAGE=javascript>
<!--
var q = new JQueryString();
document.writeln( "Name: " + q.get("name&quot

+ "<br>&quot

;
document.writeln( "Address: " + q.get("address&quot

+ "<br>&quot

;
//-->
</SCRIPT>

Hope this helps

It 'was' a good book in it's time. It still might have some value but I would be skeptical unless there is a newer version available.
