连续鼠标器

你需要使用 setInterval() :

var to;
var doStuff = function() {
    console.log('doing stuff...');
};

$('a').hover(function(e) {
    to = window.setInterval(doStuff, 1);
},function(e) {
    window.clearInterval(to);
})

//continuous


var timer;

var doStuff=function(quit){

  console.log('doing stuff');

  if (quit!==true){

    timer=setTimeout(doStuff, 100);

  }

  else{

    clearTimeout(timer);

  }

};

$('div#continuous').bind('mouseenter', doStuff).bind('mouseleave', function(){doStuff(true);});
