如何使用javascript检测IE10？ [英] How do I detect IE10 using javascript?

问题描述

由于许多已经在其他问题（也在jQuery文档中）上发布，旧的 jQuery.browser.version 已被弃用，只能在jquery1.3中使用。

As many already posted in other questions (also in jQuery documentation), the old jQuery.browser.version is deprecated and works only in jquery1.3.

你知道另一个简单的方法来检测它，我可以包含在我的代码之前：

Do you know another simple way to detect it, that I can include in my code before:

function handleInfoDivPopupVisibility(dynamicEleId, staticEleId){
var parentContainer = $('headerSummaryContainer');
var dynamicEle = $(dynamicEleId);
var staticEle = $(staticEleId);

if(isIE() && parentContainer){
    if (jQuery.browser.version != 10) { // I need to find a way to detect if it's IE10 here.
        parentContainer.style.overflow = 'visible'; 
    }
}
dynamicEle ? dynamicEle.style.display = '' : '';
if(dynamicEle && staticEle)
    gui_positionBelow(dynamicEle, staticEle);
}

在你说它的重复问题 this 或这，我想强调，我不想使用css hacks。有没有办法检测它，就像以前一样简单？

Before you say it's duplicated question of this or this, I'd like to reinforce that I don't want to use css hacks. Is there a way to detect it just as simple as I could do before?

if (jQuery.browser.version != 10) {...

推荐答案

它是一个坏主意，检查浏览器版本，它被认为是更好的做法，检查浏览器功能。但如果你确定你在做什么：

In general it's a bad idea to check for browser version, it's considered a better practice to check for browser features. But if you're sure what you're doing:

function getIEVersion(){
    var agent = navigator.userAgent;
    var reg = /MSIE\s?(\d+)(?:\.(\d+))?/i;
    var matches = agent.match(reg);
    if (matches != null) {
        return { major: matches[1], minor: matches[2] };
    }
    return { major: "-1", minor: "-1" };
}

var ie_version =  getIEVersion();
var is_ie10 = ie_version.major == 10;

我们在生产中有以下代码，所以它工作正常并经过良好测试。

We have the following code in production, so it works and well-tested.

是的，我们确实需要检测IE10，而不仅仅是IE10中存在的特殊功能，而不是早期版本。

And yes, we did have a need to detect IE10, not just a particular feature that exists in IE10 but not in earlier versions.
