這篇文章主要介紹了ExtJS判斷IE浏覽器類型的方法,需要的朋友可以參考下
代碼在ext裡的srccoreext.js下 最新的ext3.0beat1的代碼如下: 代碼如下: ua = navigator.userAgent.toLowerCase(), check = function(r){ return r.test(ua); }, isStrict = document.compatMode == "CSS1Compat", isOpera = check(/opera/), isChrome = check(/chrome/), isWebKit = check(/webkit/), isSafari = !isChrome && check(/safari/), isSafari3 = isSafari && check(/version/3/), isSafari4 = isSafari && check(/version/4/), isIE = !isOpera && check(/msie/), isIE7 = isIE && check(/msie 7/), isIE8 = isIE && check(/msie 8/), isGecko = !isWebKit && check(/gecko/), isGecko3 = isGecko && check(/rv:1.9/), isBorderBox = isIE && !isStrict, isWindows = check(/windows|win32/), isMac = check(/macintosh|mac os x/), isAir = check(/adobeair/), isLinux = check(/linux/), isSecure = /^https/i.test(window.location.protocol); 而2.2.1下(在sourcecoreext.js裡)的為 代碼如下: var ua = navigator.userAgent.toLowerCase(); var isStrict = document.compatMode == "CSS1Compat", isOpera = ua.indexOf("opera") > -1, isChrome = ua.indexOf("chrome") > -1, isSafari = !isChrome && (/webkit|khtml/).test(ua), isSafari3 = isSafari && ua.indexOf('webkit/5') != -1, isIE = !isOpera && ua.indexOf("msie") > -1, isIE7 = !isOpera && ua.indexOf("msie 7") > -1, isIE8 = !isOpera && ua.indexOf("msie 8") > -1, isGecko = !isSafari && !isChrome && ua.indexOf("gecko") > -1, isGecko3 = isGecko && ua.indexOf("rv:1.9") > -1, isBorderBox = isIE && !isStrict, isWindows = (ua.indexOf("windows") != -1 || ua.indexOf("win32") != -1), isMac = (ua.indexOf("macintosh") != -1 || ua.indexOf("mac os x") != -1), isAir = (ua.indexOf("adobeair") != -1), isLinux = (ua.indexOf("linux") != -1), isSecure = window.location.href.toLowerCase().indexOf("https") === 0;
