Retine date din URL cu Javascript
Scris: Vin Noi 02, 2012
Buna,
Am si eu o problema cu scriptul de mai jos:
Nu stiu cum sa fac sa culeaga date din URL de la o variabila (ex: [site.com/?nume=Cosmin ) dar tot cu JavaScript si sa apara in lista ca si cum asi adauga un item manual Scriptul foloseste cookie si nu pot folosi php pe server. Am nevoie tot in format de JS.
Dispun de inca un script ce preaia datele, daca ajuta la ceva , nu reusesc sa leg cele 2 scripturi si sa fac modificarea de a adauga , imi aparea doar locul gol :

function getParams() {
var idx = document.URL.indexOf('?');
var params = new Array();
if (idx != -1) {
var pairs = document.URL.substring(idx+1, document.URL.length).split('&');
for (var i=0; i<pairs.length; i++) {
nameVal = pairs[i].split('=');
params[nameVal[0]] = nameVal[1];
}
}
return params;
}
params = getParams();
</script>
<script language="JavaScript">
firstname = unescape(params["nume"]);
document.write(" + firstname + ");
