Loader is not working in IE and Chrome
<p>I have created one page in office 365 site. I have put loader inside that. Now loader is working perfectly in firefox but not working in IE and Chrome.</p>

<p>Loader is not visible. I have tried following option:
1. through hide/show method</p>

<pre><code> $('.className').hide();
 $('.className').show();
</code></pre>

<p><strong>2. through css</strong></p>

<pre><code>$('.className').css('display', 'none');

$('.className').css('display', 'block');
</code></pre>

<p><strong>3. through class</strong></p>

<pre><code>$('.className').addClass('classBlock');

$('.className').removeClass('classBlock');
</code></pre>

<p>In css I have tried both options:</p>

<pre><code>display:none/block;

visibility: hidden/visible
</code></pre>

<p>Is there any solution for this?</p>
