javascript onmousemove获取相对坐标 [英] javascript onmousemove get relative coordinates
本文介绍了javascript onmousemove获取相对坐标的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
function aim() {
var mousex = ?
}
<div class="gameArea" onmousemove="aim();"> </div>
我找不到如何在javascript中获取onmousemove事件的鼠标坐标。
I can't find how to get the mouse coordinates for an onmousemove event in javascript.
推荐答案
var guide = null;
function aim(event) {
if(window.event)
event = window.event; //grrr IE
var mousex = event.clientX - guide.offsetLeft;
alert('mouse x' + mousex)
}
function init() {
guide = document.getElementById("guide")
guide.onmousemove = aim;
}
<body onload="init();">
这似乎在两台浏览器上都有效。我不能做onmousemove =aim（）;在html中，因为它没有通过mousemove事件对象。
This appears to work on both browsers. I cant do onmousemove="aim();" in html because it doesn't pass the mousemove event object.
