在Wordpress中显示IE8，IE7，IE6的浏览器升级警告

Posted 2021-05-05

我正在开发Wordpress网站。但大多数功能都没有在IE8浏览器中显示。所以我计划显示浏览器升级警告，但它不起作用。任何人都可以帮助我。

<script> 
var $buoop = {vs:{i:9,f:15,o:12.1,s:5.1},c:2}; 
function $buo_f(){ 
 var e = document.createElement("script"); 
 e.src = "//browser-update.org/update.js"; 
 document.body.appendChild(e);
};
try {document.addEventListener("DOMContentLoaded", $buo_f,false)}
catch(e){window.attachEvent("onload", $buo_f)}
</script> 

答案

您可以使用IE条件评论：

<!--[if lt IE 9]>
<script src="//browser-update.org/update.js"></script>
<![endif]-->

另一答案

你可以试试这个

    <!--[if IE 5]>
<script language="javascript">
<!--
alert ("It looks like you aren't using Internet Explorer 7. To see our site correctly, please update.")
//-->
</script>
<![endif]-->
<!--[if IE 5.0]>
!--
alert ("It looks like you aren't using Internet Explorer 7. To see our site correctly, please update.")
//-->
</script>
<![endif]-->
<!--[if IE 5.5]>
!--
alert ("It looks like you aren't using Internet Explorer 7. To see our site correctly, please update.")
//-->
</script>
<![endif]-->
<!--[if IE 6]>
!--
alert ("It looks like you aren't using Internet Explorer 7. To see our site correctly, please update.")
//-->
</script>
<![endif]-->
