Appending Elements to HTML Head with jQuery/JavaScript
Many content management systems (CMSs) restrict the editing of HTML source for the
element. However, it is often necessary to add elements to this section, such as meta tags or links.
Question:
How can I add elements within the
section using jQuery/JavaScript, particularly above the
tag? For instance, I want to add the following meta tag:</p>
<p><meta http-equiv="X-UA-Compatible" content="IE=EmulateIE7" /></p>
<p><strong>Answer:</strong></p>
<p>To append elements to the <head> section, you can use the append() method available in both jQuery and vanilla JavaScript. Here's how:</p>
<pre class="brush:php;toolbar:false"><code class="javascript">$('head').append('<link />');</code></pre>
<p>For the specific meta tag you want to add, you can modify the code as follows:</p>
<pre class="brush:php;toolbar:false"><code class="javascript">$('head').append('<meta http-equiv="X-UA-Compatible" content="IE=EmulateIE7" />');</code></pre><p>The above is the detailed content of How to Append Elements to the HTML Head with jQuery/JavaScript?.
