(Solved) Error: Object doesn't support property or method 'querySelectorAll' in IE 7

I fixed this issue using the JQuery reference and JQuery selector $. Just replace the document.querySelectorAll with $. and refer the JQuery api in the html body tag.
Javascript Error code in IE 7:

var sliders = document.querySelectorAll('.slider');

Javascript Error Solution:

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js">

var sliders = $('.slider');
