本程序实现当鼠标在一个特定的div内悬停n秒时,判断出已经停止移动。
思路:
1.定义全局变量鼠标移动状态imouse,定时器timer。当鼠标在div内移动时,imouse值为1,相反静止时值为0;timer可以实现每过n秒就判断鼠标状态,然后把imouse重置为0;
2.div监听onmouseover。当鼠标进入区域时,就设置定时器;
3.div监听onmousemove。当鼠标移动时,设置imouse值为1;
4.div监听onmouseout。当鼠标离开时,清除定时器timer
<html> <head> <meta http-equiv="charset" content="utf-8" /> <script type="text/javascript"> var tip; var imouse = 0; var timer; function startup() { tip = document.getElementById("tip"); } function mouseIn() { timer = window.setInterval(foo, 1000); } function mouseOut() { window.clearInterval(timer); } function mouseMove() { imouse = 1; tip.innerHTML = "move"; } var foo = function() { if (imouse == 0) { tip.innerHTML = "still"; } imouse = 0; } </script> </head> <body onload="startup()"> <div id="imgArea" onmousemove="mouseMove()" onmouseover="mouseIn()" onmouseout="mouseOut()"> <!-- 这里随便放一些东西 --> </div> <div id="tip"></div> </body> </html>
