Getting viewport height using ExtJS-4X or javascript

Question

I want to get the height of the viewport using ExtJs or native javascript.

How can i get this height ? I am not using any extjs viewport container.

If its not possible using ExtJs then how can i find the exact height of the view port ?

Thanks!!

Answer 1

Using window.innerHeight solved my problem and also the ExtJs way of finding the view port height is as follows -

Ext.getBody().getViewSize().height
