我有一个元素:
<b onclick="alert('');" onmouseover="this.style.color='red'; setTimeout('........', 1000);" onmouseout="this.style.color='';">123</b>
我需要当元素被鼠标移过时,1秒后鼠标光标继续停留在此元素之上,然后onclick()此元素的事件应该开始。
换句话说,在onmouseover()事件中应该是什么而不是'..............'?
答案 0 :(得分:2)
window.countdown = setTimeout(function(){this.click();}, 1000);
此外,您需要清除mouseout处理程序中的间隔:
clearTimeout(countdown);
理想情况下,您可以为元素提供ID并使用新的事件注册模型:
var e = document.getElementById('myelement');
e.addEventListener('click',function(){
alert('');
});
e.addEventListener('mouseenter',function(){
var self = this;
this.style.color='red';
window.countdown = setTimeout(function(){self.click();}, 1000);
});
e.addEventListener('mouseleave',function(){
this.style.color='';
clearTimeout(countdown);
});

你应该将鼠标悬停事件的间隔作为全局变量开始,以引用鼠标输出事件来清除它,就像@Asad所说的那样。
<b onclick = "alert()"
onmouseover = "window.countdown = setTimeout(function(){this.click();}, 1000);"
onmouseout = "clearTimeout(countdown)">
123

你将不得不做一些额外的工作,这对于内联Javascript内部来说不会很好。这都是伪代码所以我不建议复制/粘贴!
// We'll need to create an interval and store it
var timerInterval = {}
// And keep track of how many seconds have elapsed
var timeElapsedInSeconds = 0;
function tick (){
timeElapsedInSeconds++;
if (timeElapsedInSeconds > 0){
// YOUR GREAT CODE HERE
}
// Either way, let's be sure to reset everything.
resetTimer();
}
function hoverOverHandler (){
// Start our timer on hover
timerInterval = window.setInterval(tick, 1000);
}
function resetTimer () {
timeElapsedInSeconds = 0;
window.clearInterval(timerInterval);
}
function hoverOutHandler () {
// Kill timer on hoverout
resetTimer();
}

好的,我用动态ID做了一些技巧,这就是出现的结果:
<b style="color:red;" onclick="if(this.style.color!='green'){return false;}else{this.style.color='red';} alert(this.parentNode);" onmouseover="if(this.style.color!='green'){var newID='tmpID_'+Math.floor(Math.random() * (10000000)); if(this.id==''){this.id=newID;} setTimeout('top.document.getElementById(\''+this.id+'\').onclick();',1000); this.style.color='green';}" onmouseout="this.style.color='red';">click</b>
