Web Development Browser (ii)----jquery or JS to determine the browser kernel version number and whether to support the box model

1,jquery or JS to determine the browser kernel version number and whether to support the box model

JQuery, starting with version 1.9, removed $.browser and $.browser.version and replaced it with $.support. In the updated version 2.0, IE 6/7/8 will no longer be supported. Later, if the user needs to support IE 6/7/8, only jQuery 1.9 can be used. later, if the user needs to support IE 6/7/8, only jQuery 1.9 and below can be used. If you want to fully support IE, and mix jQuery 1.9 and below and 2.0 and later, the official solution is to use only IE-recognized conditional expressions:

<!--[if Lt IE 9]><script src= ' jquery-1.9.0.js ' </script><! [endif]--><!--[if GTE IE 9]><script src= ' jquery-2.0.0.js ' </script><! [endif]-->

Jquery version 1.4.2 determine the browser type and version and whether or not to support the box model (mainly IE, other browser problems are relatively small)

$ (function ()  {            var strtmp  =  "Your browser name is:";            if  ($. Browser.msie)  { //ie Browser                  strTmp +=  "IE";             }            else  if ($. Browser.mozilla)  { //Firefox related browser                  strTmp +=  "Mozilla firefox";             }else  if ($.browser.chrome)  { //Google related browser (i test not recognized)                  strTmp +=  " Chrome ";            }else if ($.browser.safari)  //chrome,opera,are judged for this, { strtmp += "Safari";  } else if ($.browser.opera)  { strtmp + = "Opera";  } else { strtmp+= "Unknown"; }             strTmp +=  "  Version number is:"  //get version number                     + $.browser.version;   strTmp +=  "  Box model is:" if  ($.support.boxmodel)  { //is a box model                  strTmp +=  "box model";             }             else { //is IE box model                  strtmp +=  "IE box model";             }            $ ("#divTip"). HTML (STRTMP) ;         })

Whether the above judgments support the box model when I test all is the IE box model, it is said that the following code will become a model,

I'm sorry I didn't change my test results.

	Jquery1.9 Version above judge whether it is ie6-8


	


if (!$.support.leadingwhitespace) {}


	



	



	



	



	    js Judging browser type 


	


Function getos ()  {     var OsObject =  "";     if (Navigator.userAgent.indexOf ("MSIE") >0)  {          return  "MSIE";     }    else if (isfirefox= Navigator.userAgent.indexOf ("Firefox") >0) {         return   "Firefox";     }    else if (ismozilla= Navigator.userAgent.indexOf ("Opera") >0) { //This is also judged as chrome         return  "Opera";     }    else if (isfirefox= Navigator.userAgent.indexOf ("Chrome") >0) {         return  "Chrome";     }    else if (Issafari=navigator.useragent.indexof (" Safari ") >0)  {         return  "Safari";     }     else if (isCamino= Navigator.userAgent.indexOf ("Camino") >0) {         return  "Camino";     }    else if (Ismozilla=navigator.useragent.indexof (" gecko/") >0) {         return " Gecko ";     }   }  alert ("Your browser type is:" +getos ());

	



	



	



	



	The above is a little bit better than jquery, at least to identify chrome, and below this is similar to the above, is also more commonly used


	


$.browser.mozilla =/firefox/.test (Navigator.userAgent.toLowerCase ()); $.browser.webkit =/webkit/.test ( Navigator.userAgent.toLowerCase ()); $.browser.opera =/opera/.test (Navigator.userAgent.toLowerCase ()); $. Browser.msie =/msie/.test (Navigator.userAgent.toLowerCase ()), Var str= "", str+= "Firefox" +$.browser.mozilla+ "<br /> "str+=" WebKit "+$.browser.webkit+" <br/> "str+=" opera "+$.browser.opera+" <br/> "str+=" MSIE "+ $.browser.msie+ "<br/>"; $ ("#divTip"). html (str);
