Angular gets the width and height of the browser:

$ Window. innerwidth; // browser width

$ Window. innerheight; // browser height

Jquery $ jqlite gets the distance between the mouse and the browser's upper left corner:

E. pagex; // relative to left in the upper left corner of the browser

E. Pagey; // relative to the top left corner of the browser

Distance between native elements and the upper left corner of the browser:

Ele. offsetleft; // element relative to left in the upper left corner of the browser

Ele. offsettop; // element relative to top in the upper left corner of the browser

Native obtains the width and height of elements:

Ele. offsetwidth; // The width of the element, which includes padding and border.

Ele. offsetheight; // The height of the element, which includes padding and border.
