Parse variable from URL to display different content on HTML page (JS)
<p>I have an email newsletter being sent out each week with a different subject and there's one webpage where you can click to from the email.</p>

<p>On week 1 the email is about 'phones' and if someone clicked the link it could contain a slightly different variable (for example week 1 being ?content=phone on the end of the URL).</p>

<p>When the webpage loads, only the content on phones is displayed.</p>

<p>There is going to be 8 emails so there will be 8 sets of content and different variables in the URLs on each week.</p>

<p>I just need a javascript to do this?</p>
