使用JQuery在Head标记中添加元数据 [英] Using JQuery to add metadata in the Head Tag

问题描述

我正在尝试在Head内插入新的meta标签，我正在使用内容管理系统，该系统不允许在Head内进行编辑，因此我尝试使用jQuery进行此操作.不幸的是我无法正常工作.

I'm trying to insert a new meta tag within the Head, I'm using a content managment system that won't allow editing within the Head so I'm attempting to do this using jQuery. Unfortunately I can't it to work.

这是我添加到以下网页中的代码: http://www.newcastlegateshead.com

This is the code I've added to the following webpage: http://www.newcastlegateshead.com

<script type="text/javascript"> 
$("head").append("<meta name=viewport content=width=400, initial-scale=0.45, minimum-    scale=0.45/><link rel=apple-touch-icon href=/images/customIcon.png/><meta name=apple-mobile-web-app-capable content=no /><meta name=apple-mobile-web-app-status-bar-style content=black-translucent /><link rel=apple-touch-icon-precomposed href=/images/customIcon.png/> ");
</script>

推荐答案

在内部尝试代码

<script type="text/javascript"> 
     $(document).ready(function() {
         $("head").append("<meta name=viewport content=width=400, initial-scale=0.45, minimum-    scale=0.45/><link rel=apple-touch-icon href=/images/customIcon.png/><meta name=apple-mobile-web-app-capable content=no /><meta name=apple-mobile-web-app-status-bar-style content=black-translucent /><link rel=apple-touch-icon-precomposed href=/images/customIcon.png/> ");
    });
</script>

$(document).ready(function() {...})的简写形式是:

jQuery(function ($) {
    // Your code
})

这将确保您的代码将在 onload期间执行. .

This will ensure that you code will execute during onload.
