JQuery 获取元素 .height() 然后减去 100vh？

Question

How would one subtract a 100vh from a .height() value for example $('#luxy').height(); the height is 5000px I want to take 100vh from the 5000px using jQuery or Javascript not CSS?

Answer 1

vh is a unit representing 1% of the V iewport H eight

window.innerHeight is the px value of the height of the viewport

Being as both of these are targeting the layout viewport , you should be fine to do:

let myHeight = $('#luxy').height() - window.innerHeight;
