项目 | 范例 | 说明 |
---|---|---|
! | [if !IE] | The NOT operator. This is placed immediately in front of the feature, operator, or subexpression to reverse the Boolean meaning of the expression. NOT运算符。这是摆立即在前面的功能,操作员,或子表达式扭转布尔表达式的意义。 |
lt | [if lt IE 5.5] | The less-than operator. Returns true if the first argument is less than the second argument. 小于运算符。如果第一个参数小于第二个参数,则返回true。 |
lte | [if lte IE 6] | The less-than or equal operator. Returns true if the first argument is less than or equal to the second argument. 小于或等于运算。如果第一个参数是小于或等于第二个参数,则返回true。 |
gt | [if gt IE 5] | The greater-than operator. Returns true if the first argument is greater than the second argument. 大于运算符。如果第一个参数大于第二个参数,则返回true。 |
gte | [if gte IE 7] | The greater-than or equal operator. Returns true if the first argument is greater than or equal to the second argument. 大于或等于运算。如果第一个参数是大于或等于第二个参数,则返回true。 |
( ) | [if !(IE 7)] | Subexpression operators. Used in conjunction with boolean operators to create more complex expressions. 子表达式运营商。在与布尔运算符用于创建更复杂的表达式。 |
& | [if (gt IE 5)&(lt IE 7)] | The AND operator. Returns true if all subexpressions evaluate to true AND运算符。如果所有的子表达式计算结果为true,返回true |
| | [if (IE 6)|(IE 7)] | The OR operator. Returns true if any of the subexpressions evaluates to true. OR运算符。返回true,如果子表达式计算结果为true。 |
js判断见下面:
(function(window) { var theUA = window.navigator.userAgent.toLowerCase(); if ((theUA.match(/msie\s\d+/) && theUA.match(/msie\s\d+/)[0]) || (theUA.match(/trident\s?\d+/) && theUA.match(/trident\s?\d+/)[0])) { var ieVersion = theUA.match(/msie\s\d+/)[0].match(/\d+/)[0] || theUA.match(/trident\s?\d+/)[0]; if (ieVersion < 9) { var str = "你的浏览器版本太low了,已经和时代脱轨了 :("; var str2 = "推荐使用:<a href='https://www.baidu.com/s?ie=UTF-8&wd=%E8%B0%B7%E6%AD%8C%E6%B5%8F%E8%A7%88%E5%99%A8' target='_blank' style='color:blue;'>谷歌</a>," + "<a href='https://www.baidu.com/s?ie=UTF-8&wd=%E7%81%AB%E7%8B%90%E6%B5%8F%E8%A7%88%E5%99%A8' target='_blank' style='color:blue;'>火狐</a>," + "其他双核极速模式"; document.writeln("<pre style='text-align:center;color:#fff;background-color:#0cc; height:100%;border:0;position:fixed;top:0;left:0;width:100%;z-index:1234'>" + "<h2 style='padding-top:200px;margin:0'><strong>" + str + "<br/></strong></h2><h2>" + str2 + "</h2><h2 style='margin:0'><strong>如果你的使用的是双核浏览器,请切换到极速模式访问<br/></strong></h2></pre>"); document.execCommand("Stop"); }; } })(window);
