@ExuroOct 30.2004 — Try this code:
[code=php]function getParam(paramName) {
var rx = new RegExp("^\?.*"+paramName+"=([^;]+)(;|$)");
var ar = rx.exec(unescape(location.search));
if (ar) {
return ar[1];
}
else {
return null;
}
}
// Set the document's onload function
window.onload = function () {
alert(getParam("a"));
}[/code]
If your query string was [FONT=courier new]"?nums=123four"[/FONT] then [FONT=courier new]getParam("nums")[/FONT] would return [FONT=courier new]"123four"[/FONT]. Anyway, I hope that helps!
