又整理了一个,特性检测:
var browser=function(){//尽量使用特性去检测
var ua=navigator.userAgent,
b = {
ie : !!window.ActiveXObject,
//!+'\v1'
//!!window.VBArray
ie6 : !"1"[0],
ie67 : /MSIE [67]/.test(ua),
ie9 : !!document.documentMode && document.documentMode===9,
chrome : !!(window.google && window.chrome),
firefox : !!window.Components,
safari : !!navigator.vendor && !top.chrome,//(!navigator.taintEnabled && !window.chrome), 奇怪的IE6/7报错,
opera : !!window.opera,
version : (ua.match(/\s+(?:MSIE|Chrome|Firefox|Version)[ \/]([\d.]+)/) || [0,0])[1]
};
return b
}()
//显示结果
document.write("<br/><br/>"+navigator.userAgent+"<br/>")
var c=browser;
for(var n in c){
document.write(n+" : "+c[n]+"<br/>")
}
var ua=navigator.userAgent,
b = {
ie : !!window.ActiveXObject,
//!+'\v1'
//!!window.VBArray
ie6 : !"1"[0],
ie67 : /MSIE [67]/.test(ua),
ie9 : !!document.documentMode && document.documentMode===9,
chrome : !!(window.google && window.chrome),
firefox : !!window.Components,
safari : !!navigator.vendor && !top.chrome,//(!navigator.taintEnabled && !window.chrome), 奇怪的IE6/7报错,
opera : !!window.opera,
version : (ua.match(/\s+(?:MSIE|Chrome|Firefox|Version)[ \/]([\d.]+)/) || [0,0])[1]
};
return b
}()
//显示结果
document.write("<br/><br/>"+navigator.userAgent+"<br/>")
var c=browser;
for(var n in c){
document.write(n+" : "+c[n]+"<br/>")
}
ua检测:
var bb=function(){
var ua=navigator.userAgent,
check=function(r){return r.test(ua)},
b = {
ie : check(/MSIE/),
ie6 : check(/MSIE 6/),
ie67 : check(/MSIE [67]/),
ie9 : check(/MSIE 9/),
chrome : check(/Chrome/),
firefox : check(/Firefox/),
safari : check(/Safari/) && !top.chrome,
opera : check(/Opera/),
version : (ua.match(/\s+(?:MSIE|Chrome|Firefox|Version)[ \/]([\d.]+)/) || [0,0])[1]
};
return b
}()
var ua=navigator.userAgent,
check=function(r){return r.test(ua)},
b = {
ie : check(/MSIE/),
ie6 : check(/MSIE 6/),
ie67 : check(/MSIE [67]/),
ie9 : check(/MSIE 9/),
chrome : check(/Chrome/),
firefox : check(/Firefox/),
safari : check(/Safari/) && !top.chrome,
opera : check(/Opera/),
version : (ua.match(/\s+(?:MSIE|Chrome|Firefox|Version)[ \/]([\d.]+)/) || [0,0])[1]
};
return b
}()
