即使鼠标仍然存在，jQuery mousemove（）也会被调用 [英] jQuery mousemove() is called even if the mouse is still

问题描述

对我来说，如果我尝试这个例子： http://jsfiddle.net/bY3CC/3/

为什么？ ; \

另外，好像消息只出现在Chrome浏览器....

奇怪： -s

解决方案

全局事件对象是非标准的，所以它只存在于一些浏览器中，比如IE（也许只有在怪癖模式下）以及在Chrome中出现。

接受event对象作为事件处理函数的参数：

  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; 
} 
}）;

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;
  }
});
