he visto q muchas webs de PWG ponen anuncios de descarga de firefox en sus webs para q lo descargen y la web se vea mejor,
pero esto no tiene sentido cuando el q visita la web ya esta usando firefox y ademas se ase algo molesto no??
e consegido un codigo q identifica cual navegador esta usando el visitante, y si no es firefox muestra el anuncio, pero si ya tiene firefox, no lo muestra:
Código: <!-- Firefox -->
<script type="text/javascript">
//detección del navegador por http://www.quirksmode.org/js/detect.html
var BrowserDetect = {
init: function () {
this.browser = this.searchString(this.dataBrowser) || "An unknown browser";
this.version = this.searchVersion(navigator.userAgent)
|| this.searchVersion(navigator.appVersion)
|| "an unknown version";
this.OS = this.searchString(this.dataOS) || "an unknown OS";
},
searchString: function (data) {
for (var i=0;i<data.length;i++) {
var dataString = data[i].string;
var dataProp = data[i].prop;
this.versionSearchString = data[i].versionSearch || data[i].identity;
if (dataString) {
if (dataString.indexOf(data[i].subString) != -1)
return data[i].identity;
}
else if (dataProp)
return data[i].identity;
}
},
searchVersion: function (dataString) {
var index = dataString.indexOf(this.versionSearchString);
if (index == -1) return;
return parseFloat(dataString.substring(index+this.versionSearchString.length+1));
},
dataBrowser: [
{ string: navigator.userAgent,
subString: "OmniWeb",
versionSearch: "OmniWeb/",
identity: "OmniWeb"
},
{
string: navigator.vendor,
subString: "Apple",
identity: "Safari"
},
{
prop: window.opera,
identity: "Opera"
},
{
string: navigator.vendor,
subString: "iCab",
identity: "iCab"
},
{
string: navigator.vendor,
subString: "KDE",
identity: "Konqueror"
},
{
string: navigator.userAgent,
subString: "Firefox",
identity: "Firefox"
},
{
string: navigator.vendor,
subString: "Camino",
identity: "Camino"
},
{ // for newer Netscapes (6+)
string: navigator.userAgent,
subString: "Netscape",
identity: "Netscape"
},
{
string: navigator.userAgent,
subString: "MSIE",
identity: "Explorer",
versionSearch: "MSIE"
},
{
string: navigator.userAgent,
subString: "Gecko",
identity: "Mozilla",
versionSearch: "rv"
},
{ // for older Netscapes (4-)
string: navigator.userAgent,
subString: "Mozilla",
identity: "Netscape",
versionSearch: "Mozilla"
}
],
dataOS : [
{
string: navigator.platform,
subString: "Win",
identity: "Windows"
},
{
string: navigator.platform,
subString: "Mac",
identity: "Mac"
},
{
string: navigator.platform,
subString: "Linux",
identity: "Linux"
}
]
};
BrowserDetect.init();
if (BrowserDetect.browser != "Firefox") {
document.write('<div style="position: absolute; left: 0px; top: 0px;"><a href="http://www.mozilla-europe.org/es/firefox/"><img src="http://img300.imageshack.us/img300/6920/firefoxaq2.gif" border="0" alt="Descarga Firefox" /></a></div>');
}
</script>
la parte q dice :
Código: <div style="position: absolute; left: 0px; top: 0px;"><a href="http://www.mozilla-europe.org/es/firefox/"><img src="http://img300.imageshack.us/img300/6920/firefoxaq2.gif" border="0" alt="Descarga Firefox" /></a></div>
la pueden editar a su gusto, ya q ese es el anuncio
espero q les sirva! |
