怎么判断点击是靠近屏幕偏右边还是偏左边

Question

如何判断当我点击时候,我点击的位置是靠近左边或者右边的屏幕最近

Answer 1

document.addEventListener('click', function (e) {&nbsp; // console.log(e);&nbsp; const leftInstance = e.screenX;&nbsp; const rightInstance = e.screenY;&nbsp; const screenWidth = window.innerWidth;&nbsp; if (leftInstance < (screenWidth / 2)) {&nbsp; &nbsp; alert('靠左边');&nbsp; } else {&nbsp; &nbsp; alert('靠右边');&nbsp; }}, false)

Answer 2

获取屏幕宽度,获取点击时的坐标,判断x值是接近0还是接近屏幕宽度值,不就是接近左边或是右边？
