如果IE条件不起作用
[英]if IE Condition Doesn't Work
问题描述
I have 2 sections of code for IE and other (Chrome, FF). 
我有IE和其他（Chrome，FF）代码的2个部分。 I am using IE8 and it is STAYING outside <!--[if IE]>... <![endif]--> , any function inside ... doesn't work. 我正在使用IE8，并且在<!--[if IE]>... <![endif]-->外面停留，里面的任何功能都无法正常工作。 However, it is GOING inside <!--[if !IE]><!-->....<!--<![endif]--> , which I don't expect it goes through. 但是，它正在<!--[if !IE]><!-->....<!--<![endif]--> ，我不希望它会通过。 (I also try some more syntax such as <!-- [if !IE] -->...<!-- [endif] --> but it seems not ignore!). （我还尝试了其他语法，例如<!-- [if !IE] -->...<!-- [endif] -->但似乎不能忽略！）。
I don't know for sure if <meta> tags cause the problems. 我不确定<meta>标签是否会引起问题。 Please take a look. 请看一下。
<head>
<meta content="text/html; charset=iso-8859-1" http-equiv="Content-Type"/>
<meta content="no-cache; post-check=0; pre-check=0" http-equiv="Cache-Control"/>
<meta content="no-cache" http-equiv="Pragma"/>
<meta content="Thu, 01 Dec 1994 16:00:00 GMT" http-equiv="Expires"/>
<!--[if IE]>
<script>
$(document).ready(function() {
$(".exportExcel").click(function(e) {
e.stopPropagation();
var table = $("." + $(this).data('target'));
var strCopy = $('<div></div>').html(table.clone()).html(); window.clipboardData.setData("Text", strCopy);
var objExcel = new ActiveXObject("Excel.Application");
objExcel.visible = false;
var objWorkbook = objExcel.Workbooks.Add;
var objWorksheet = objWorkbook.Worksheets(1);
objWorksheet.Paste;
objExcel.visible = true;
});
});
</script>

<!--[if !IE]><!-->

window.open('data:application/vnd.ms-excel,' + $(table).html());
e.preventDefault();
});
}

Turn off your compatibility mode in IE8, then try. 在IE8中关闭兼容模式，然后尝试。 It may only work in standard and quirks modes. 它只能在标准和怪异模式下工作。
Have you tried adding the meta tag <meta http-equiv="X-UA-Compatible" content="IE=edge"> 您是否尝试过添加元标记<meta http-equiv="X-UA-Compatible" content="IE=edge">
These are all the tags on our page and it works 这些都是我们页面上的所有标签，它可以正常工作
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1">

IE conditionals are no longer supported in IE, as of 10 从10开始，IE中不再支持IE条件

If it's just JavaScript, then you can check for the browser version and run a different function depending on the browser. 如果只是JavaScript，则可以检查浏览器版本并根据浏览器运行其他功能。
<script>
$(document).ready(navigator.appName == 'Microsoft Internet Explorer' ?
function(){ /* IE code */ } :
function(){ /* Non-IE code */ });
</script>
Other ways to detect IE: 检测IE的其他方法：
console.log($.browser.msie);
console.log('ActiveXObject' in window);
console.log(!!window.navigator.userAgent.match(/(MSIE |Trident\/)\d+/));
