即使鼠标仍然存在，jQuery mousemove（）也会被调用

本文介绍了即使鼠标仍然存在，jQuery mousemove（）也会被调用的处理方法，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

对我来说，如果我尝试这个例子：

For me, if I try this example: http://jsfiddle.net/bY3CC/3/ the "mouse moved" text appears even if I move my mouse over the document and then I let it still...

Why's that? ;\

And also, seems like the message only appears in Chrome....

Strange :-s

解决方案

The global event object is non-standard, so it only exists in some browsers, like IE (perhaps only in quirks mode) and appearently in Chrome.

Accept the event object as a parameter to the event handler:

var last_moved=0;
$(document).mousemove(function(e){
  var now = e.timeStamp;
  if (now - last_moved > 1000) {
    $('#messages').append('mouse moved<br/>');
    last_moved = now;
  }
});
