Browser sniffing, o functie pentru DOM (document object model) de pe vremea lui Netscape s.a. Prima chestie era deja chemata dintr-o alta functie prezentata data trecuta (sooo, sorry daca ati testat ceva si nu v-a mers din cauza asta 🙂 ). Here we go:

[sourcecode language=’jscript’]
/* ———– EVALUATION ————– */

//browser sniffer: conditiile sunt if (is.ns) etc.

function appName() {
var agent = navigator.userAgent.toLowerCase();
this.major = parseInt(navigator.appVersion);
this.ns = ((agent.indexOf(‘mozilla’)!=-1) && ((agent.indexOf(‘spoofer’)==-1) && (agent.indexOf(‘compatible’) == -1)));
this.ns3 = (this.ns && (this.major >= 3));
this.ns4 = (this.ns && (this.major >= 4));
this.ie = (agent.indexOf(“msie”) != -1);
this.ie3 = (this.ie && (this.major == 2));
this.ie4 = (this.ie && (this.major >= 4));
this.op3 = (agent.indexOf(“opera”) != -1);
this.win = (agent.indexOf(“win”)!=-1);
this.mac = (agent.indexOf(“mac”)!=-1);
this.unix = (agent.indexOf(“x11”)!=-1);
}
var is= new appName();

/* short version

function appName() {
var agent = navigator.userAgent.toLowerCase();
this.major = parseInt(navigator.appVersion);
this.ns = ((agent.indexOf(‘mozilla’)!=-1) && ((agent.indexOf(‘spoofer’) == -1) && (agent.indexOf(‘compatible’) == -1)));
this.ns3 = (this.ns && (this.major >= 3));
this.ns4 = (this.ns && (this.major >= 4));
this.ie = (agent.indexOf(“msie”) != -1);
this.ie4 = (this.ie && (this.major >= 4));
}
var is= new appName()

}

//get the name of a file from its absolute adress (sometimes it’s usefull)
function getName(fileAdress){

temp1= temp0.split(“/”);
retValue= temp1[temp1.length-1];
