如何模拟触摸设备上的悬停效果? [英] How to simulate hover effect on touch devices?
问题描述
我有一个悬停的css3动画网页,当用户触摸这些元素时,我想让它在iPad(以及任何支持触摸的设备)上工作。
这是我的代码:
html:
< div id =headBlock>
< a id =arm>< / a>
< div id =head>
< div id =blink>< / div>
< div id =lid>< / div>
< div id =man>< / div>
< a id =man-arm>< / a>
< / div>
< / div>
js:
< code $ // $ arm $ b $('#arm')。hover(function(){
$(this).removeAttr('style')。css('bottom','244px ');
$(this).addClass('hover_effect');
},function(){
$(this).removeClass('hover_effect');
});
// man arm
$('#man')。hover(function(){
$('#man-arm')。removeAttr('style') ;
$('#man-arm')。addClass('hover_effect');
},function(){
$('#man-arm')。 removeClass('hover_effect');
});
您可以看到,当鼠标进入元素时,我删除样式,然后应用样式并添加css class'hover_effect',当鼠标离开时,我删除'hover_effect'类。
如何在触摸设备上实现相同的功能?点击事件没有回调,所以点击发生后我无法删除'hover_effect'类。我尝试了mousedown和mouseup,但没有奏效。我搜索了stackoverflow,我发现这个如何在支持触摸的浏览器中模拟悬停触摸?,但它没有任何作用。
任何人都可以想到吗?
谢谢

试试这个
$ b $($'pre>
$('#arm')。bind('touchstart',function(){
$(this).removeAttr('style')。css 'bottom','244px');
$(this).addClass('hover_effect');
});
$ b $('#arm')。bind('touchend',function(){
$(this).removeClass('hover_effect');
});
同样适用于 $('#man')。
I have a web page with some css3 animation on hover and I would like to make it work on iPad (and any touch enabled device) when the user touch these elements.
Here's my code:
html:
<div id="headBlock">
<a id="arm"></a>
<div id="head">
<div id="blink"></div>
<div id="lid"></div>
<div id="man"></div>
<a id="man-arm"></a>
</div>
</div>
js:
//arm
$('#arm').hover(function(){
$(this).removeAttr('style').css('bottom','244px');
$(this).addClass('hover_effect');
}, function(){
$(this).removeClass('hover_effect');
});
//man arm
$('#man').hover(function(){
$('#man-arm').removeAttr('style');
$('#man-arm').addClass('hover_effect');
}, function(){
$('#man-arm').removeClass('hover_effect');
});
You can see that when the mouse enter the elements I remove the style then apply a style and add the css class 'hover_effect' and when the mouse leaves I remove the 'hover_effect' class.
How can I achieve the same thing on touch devices? The click event doesn't have the a callback so I cannot remove the 'hover_effect' class after the click happens. I tried mousedown and mouseup but it didn't work. I searched stackoverflow and I found this How do I simulate a hover with a touch in touch enabled browsers? but it didn't have any effect.
Any idea anyone?
Thanks
Mauro
try this
$('#arm').bind('touchstart', function() {
$(this).removeAttr('style').css('bottom','244px');
$(this).addClass('hover_effect');
});
$('#arm').bind('touchend', function() {
$(this).removeClass('hover_effect');
});
similarly for $('#man').
