即使版本是 IE 10，下面的代碼也會生成警報“支持您的瀏覽器”。它與 IE 9、8 和 7 等瀏覽器完美配合。我需要確保只允許 IE 11 版本。代碼真的有什么問題嗎？
<script type="text/javascript">
jQuery(document).ready(function($){
// true on IE11
// false on Edge and other IEs/browsers. filters.hide();
// Allow only IE 11 and other browsers like Chrome, Safar, firefox so on,
// but never allow lower versions of IE starting IE 10.
var div = document.createElement("div");
div.innerHTML = "<!--[if lt IE 11]><i></i><![endif]-->";
var isIeLessThan11 = (div.getElementsByTagName("i").length == 1);
if (isIeLessThan11) {
alert("Your web browser is out of date. Please complete this form using an approved browser, such as Edge, Chrome, Safari, or Firefox.");
} else {
alert("Your browser is supported");
}
});
</script>

根據 wikipedia，IE10 及更高版本不支持條件注釋。https://en.m.wikipedia.org/wiki/Conditional_comment
