因特網探索瀏覽器檢測

我有這個JavaScript來檢測瀏覽器，但它不能在IE9中工作。我找到了幾個例子，但不能使它與我的代碼一起工作。是否有人可以提醒我，以便它可以在所有瀏覽器中正常工作。因特網探索瀏覽器檢測

爲了公平起見，使用「的userAgent」字符串不這樣做的好方法。最好檢查瀏覽器是否支持功能，然後實現（或不實現）瀏覽器支持的網站的特定功能。

一些網站，可以幫助你是http://diveintohtml5.info/detect.html和http://modernizr.com/

檢查.ie9類，該類添加到您的<html>元素中。

編輯使用的hasClass代替length

if ($("html").hasClass("ie9")) { 

}

感謝您的評論。至於javascript，我有正確的語法嗎？ – user1781367

'.length'不是一個函數。使用'.hasClass（）'更清潔。 '$（「HTML」）。hasClass（「IE9」）'。或'$（「html」）。（「。ie9」）'稍微短一些。 –

糟糕，你是對的，編輯反思。 – potench

爲了檢測MSIE（V6 - V7 - V8 - V9 - V10 - V11）輕鬆

if (navigator.userAgent.indexOf('MSIE') !== -1 || navigator.appVersion.indexOf('Trident/') > 0) { 
    // MSIE 
}

function runvlc(){ 
if (navigator.userAgent.toLowerCase().indexOf("msie")!==-1|| 
(navigator.appVersion.indexOf('Trident/') > 0)){ 
alert('iexplorer') 
} 
else if (navigator.userAgent.toLowerCase().indexOf("msie")==-1){ 
alert('others') 
} 
};

這一個工程。
