Finding Device width [duplicate]

Question

How to find the device width using the view port meta tag.

Also wants to display the device width in the console with

java script.

Answer 1

The viewport dimensions can be gotten through the window object:

var viewport = {
    width  : $(window).width(),
    height : $(window).height()
};

//can access dimensions like this:
//viewport.height

Though you won't always get perfect results, different devices behave differently and this gives the viewport dimensions, not the screen dimensions.
