每3秒获得一次鼠标位置 [英] getting mouse position every 3 seconds

问题描述

我希望每隔3秒在页面上协调鼠标，但在setInterval函数中未定义Event对象。

I want to get mouse coordinated on page every 3 seconds, but Event object is undefined in setInterval function.

function mouse() {
  console.log(window.event) // => undefined
}
setInterval(mouse, 3000)

如何处理它？

推荐答案

var m_pos_x,m_pos_y;
window.onmousemove = function(e) { m_pos_x = e.pageX;m_pos_y = e.pageY; }
setInterval(function() { console.log("x= " + m_pos_x + "y = " + m_pos_y); },3000);
