Les fonctions de la classe suivante permettent de bâtir un tableau associatif à partir d'une chaîne (par exemple une requête CGI) en spécifiant deux séparateurs (dans notre exemple, "&" et "+").

function NameValue(strNameValue, r, c) {
	var arrNameValue = strNameValue.split(r);
	if (arrNameValue[0]) 
        for (i=0; i<arrNameValue.length; i++)

	this.NameValue = arrNameValue;
	this.r = r;
	this.c = c;
	this.Get = NameValue_Get;
	this.Set = NameValue_Set;
	this.Join = NameValue_Join;
	this.Remove = NameValue_Remove;
}

	function NameValue_Get(Name) {
		var sreturn = ""

                this.NameValue[this.NameValue.length] = new Array(Name,Value);
