Posted 2022-04-09 helloworld6379

注意：一下方法只适用于IE11 以下：

TypeError: Cannot read property ‘msie‘ of undefined  

jquery1.9去掉了 $.browser  所以报错 官方说明 ： https://api.jquery.com/jQuery.browser/

/**
 * Returns the version of Internet Explorer or a -1

function getInternetExplorerVersion()

    var rv = -1; // Return value assumes failure.

    if (navigator.appName == ‘Microsoft Internet Explorer‘)
    
        var ua = navigator.userAgent;
        var re  = new RegExp("MSIE ([0-9]1,[\.0-9]0,)");
        if (re.exec(ua) != null)
            rv = parseFloat( RegExp.$1 );
    

    return rv;


function checkVersion()

    var msg = "You‘re not using Internet Explorer.";
    var ver = getInternetExplorerVersion();

    if ( ver > -1 )
    
        if ( ver >= 8.0 ) 
            msg = "You‘re using a recent copy of Internet Explorer."
        else
            msg = "You should upgrade your copy of Internet Explorer.";
    

    alert( msg );

// ----------------------------------------------------------
// A short snippet for detecting versions of IE in javascript
// without resorting to user-agent sniffing
// ----------------------------------------------------------
// If you‘re not in IE (or IE version is less than 5) then:
//     ie === undefined
// If you‘re in IE (>=5) then you can determine which version:
//     ie === 7; // IE7
// Thus, to detect IE:
//     if (ie) 
// And to detect the version:
//     ie === 6 // IE6
//     ie > 7 // IE8, IE9 ...
//     ie < 9 // Anything less than IE9
// ----------------------------------------------------------

// UPDATE: Now using Live NodeList idea from @jdalton

var ie = (function()

    var undef,
        v = 3,
        div = document.createElement(‘div‘),
        all = div.getElementsByTagName(‘i‘);

    while (
        div.innerhtml = ‘<!--[if gt IE ‘ + (++v) + ‘]><i></i><![endif]-->‘,
        all[0]
    );

    return v > 4 ? v : undef;

());

if (navigator.userAgent.toLowerCase().indexOf(‘msie 6‘) != -1)

6为你要测试的版本号
