Using JS to get AJAX data

Using JS to get AJAX data

I have a ajax php file which retrieves a list of data from my database.
Now, I need that data loaded with JS into an html.
The data is shown up like this (raw text):
var data=[{"a":"1","b":"Post
title1","c":"Category","d":"seo-url"},{"a":"2","b":"Post
title2","c":"Category","d":"seo-url"},{"a":"3","b":"Post
title3","c":"Category","d":"seo-url"}]
I need that data to be prased and loaded like this in the html file:
<a href="website.com/[seo-url]" title="[Post title]"><p>[Post
title]<p>Category: [Category]</a>
How can I do it?
