CMultiFileUpload Error

Yii 2.0 Extensions
1

I am using CMultiFileUpload widget in the view.

Main goal is to check if the file size more than 1 MB. If it is alert a message.

I am trying to alert the filesize. It works fine in Chrome and Mozilla but not in IE

IE error: [color="#FF0000"]Unable to get property ‘0’ of undefined or null reference.[/color]

Here is my code

<?php $this->widget(‘CMultiFileUpload’,

					array(


   							'model'=&gt;&#036;model,


   							'attribute' =&gt; 'images',


   							'accept'=&gt; 'doc|docx|pdf|txt',


  							'denied'=&gt;'Only doc,docx,pdf and txt are allowed', 


   							'max'=&gt;4,


   							'remove'=&gt;'[x]',


   							'duplicate'=&gt;'Already Selected',











						'options'=&gt;array(





        							'afterFileSelect'=&gt;'function(e ,v ,m){





           								alert(e.files[0].size);


       							 }' 





    						)














                      


   					));?&gt;
