Jquery 鼠标悬停效果在

我正在制作我的 1 页作品集,但我被困在这 1 位 jquery 上。我有 2 个伪按钮,它们只是页面上的链接。我正在使用 jquery 动态添加这些链接内部的空白,然后切换这些跨度上的不透明度,这样我看起来就像在为按钮设置动画。我的叠加跨度图像颜色较浅,因此有点发光。我在此页面上有一个联系表单,我想向提交按钮添加相同的按钮效果。这在 IE 和 Chrome 中有效,但在 FF 中无效。在 FF 中,鼠标悬停似乎永远不会在嵌套在按钮内的元素上触发。它确实按链接上的计划工作,所以我不确定是什么导致该元素无法遵守。文本缩进在 FF 中也不起作用,因此实际的按钮文本会消失,取而代之的是背景图像。

这是我的标记:

<div id="buttons" class="clearfix">
    <a id="worksbutton" title="<?php _e('View My Work');?>" class="scroll" href="#works"><?php _e('View My Work');?></a>
    <a id="contactbutton" title="<?php _e('Contact Me');?>" class="scroll" href="#contact"><?php _e('Contact Me');?></a>    
</div>

后来我有以下按钮,我希望以相同的方式表现:

<button type="submit" id="sendbutton1">Send</button>

这是我用来在每个链接和按钮内部添加一个空的span标签的jquery(不透明度为0) ,后面是我在鼠标悬停时将跨度的不透明度动画为 100% 的代码。这对于链接非常有用。

$('#buttons a, #sendbutton1').each(function() {
    var button = $(this).html();
    $(this).html("<span></span>" + button);
    $(this).children("span").css("display","block").css("opacity","0");
  });

$('#buttons a span, #sendbutton1 span').live('mouseover mouseout', function(event) {
  if (event.type == 'mouseover') {
    // animate opacity to full on mouseover
    $(this).stop().animate({
        opacity: 1
    }, "slow");
  } else {
    // animate opacity to nill on mouseout
    $(this).stop().animate({
        opacity: 0
    }, "slow");
  }
});

最后是我在链接和按钮上使用的 CSS,

#buttons a{
height: 61px;
width: 161px;
display:inline-block;
text-indent: -9999px;
background: url(images/sprite1.png) no-repeat;
position: relative;
text-align:center;
}

#buttons a span {
background:url(images/sprite1.png) no-repeat;
display:none;
position:absolute;
top:0;
left:0;
height:inherit;
width:inherit;
z-index:100;
}

a#worksbutton{
background-position: -161px 0;
}

a#worksbutton span{
background-position: -161px -61px;
}

a#contactbutton{
background-position: -322px 0;
}

a#contactbutton span{
background-position: -322px -61px;
}


#form-container button#sendbutton1{
    display: block;
    background: url(images/sprite1.png) no-repeat left -2px;
    border: none;
    height: 61px;
    width: 145px;
    padding: 0;
    margin:0;
    cursor: pointer;
    text-indent: -9999px;
}

button#sendbutton1 span {
    background: url(images/sprite1.png) no-repeat left -61px;
    height: inherit;
    width: inherit;
    z-index:100;
}

这让我有点抓狂。这是一个错误还是我错过了什么?真的可以用你新的眼光来看待这个。谢谢!

编辑:在这篇文章的评论中:http://stopdesign。 com/archive/2009/02/04/recreating-the-button.html 我找到了按钮上的 firefox“幻影填充”的解决方案。

button::-moz-focus-inner { padding: 0; border-style: none; }

哈扎!当然,然后我发现 IE 会在动画透明图像上窒息并呈现一个看起来很糟糕的黑色边框,所以我作弊并分配了一个白色背景颜色(这将起作用,因为我的背景是白色的,但违背了透明 PNG 的目的,限制了我的背景选择)

I'm working on my 1 page portfolio, but am stuck on this 1 bit of jquery. I have 2 pseudo buttons that are just on-page links. I am using jquery to dynamically add an empty inside of those links, then toggle the opacity on those spans such that I appear to be animating the button. My overlaying span image is lighter in color so it sort of glows. I have a contact form on this page and I wanted to add the same button effect to the submit button. This is working in IE and Chrome, but NOT in FF. In FF, the mouseover never seems to be triggered on the element nested inside the button. It does work as planned on the links, so I am not sure what makes this element fail to comply. The text-indent is also not working in FF so that the actual button text is disappeared away in favor of the background image.

here is my markup:

<div id="buttons" class="clearfix">
    <a id="worksbutton" title="<?php _e('View My Work');?>" class="scroll" href="#works"><?php _e('View My Work');?></a>
    <a id="contactbutton" title="<?php _e('Contact Me');?>" class="scroll" href="#contact"><?php _e('Contact Me');?></a>    
</div>

and later i have the following button that i'd like to behave the same way:

<button type="submit" id="sendbutton1">Send</button>

here is the jquery i am using to add an empty span tag inside of each link and the button (with an opacity of 0), followed by the code i have for animating the opacity of the span to 100% on mouseover. this works great for the links.

$('#buttons a, #sendbutton1').each(function() {
    var button = $(this).html();
    $(this).html("<span></span>" + button);
    $(this).children("span").css("display","block").css("opacity","0");
  });

$('#buttons a span, #sendbutton1 span').live('mouseover mouseout', function(event) {
  if (event.type == 'mouseover') {
    // animate opacity to full on mouseover
    $(this).stop().animate({
        opacity: 1
    }, "slow");
  } else {
    // animate opacity to nill on mouseout
    $(this).stop().animate({
        opacity: 0
    }, "slow");
  }
});

and finally the CSS i am using on the links and on the button

#buttons a{
height: 61px;
width: 161px;
display:inline-block;
text-indent: -9999px;
background: url(images/sprite1.png) no-repeat;
position: relative;
text-align:center;
}

#buttons a span {
background:url(images/sprite1.png) no-repeat;
display:none;
position:absolute;
top:0;
left:0;
height:inherit;
width:inherit;
z-index:100;
}

a#worksbutton{
background-position: -161px 0;
}

a#worksbutton span{
background-position: -161px -61px;
}

a#contactbutton{
background-position: -322px 0;
}

a#contactbutton span{
background-position: -322px -61px;
}


#form-container button#sendbutton1{
    display: block;
    background: url(images/sprite1.png) no-repeat left -2px;
    border: none;
    height: 61px;
    width: 145px;
    padding: 0;
    margin:0;
    cursor: pointer;
    text-indent: -9999px;
}

button#sendbutton1 span {
    background: url(images/sprite1.png) no-repeat left -61px;
    height: inherit;
    width: inherit;
    z-index:100;
}

This one is driving me a little batty. Is this a bug or am I missing something? Could really use your fresh eyes on this one. Thanks!

EDIT: in the comments on this post: http://stopdesign.com/archive/2009/02/04/recreating-the-button.html i found the solution to the firefox "phantom padding" on my button.

button::-moz-focus-inner { padding: 0; border-style: none; }

huzzah! of course then i found that IE will choke on animating transparent images and render an awful-looking black border, so I have cheated and assigned a white background color (which will work since my background is white, but defeats the purpose of transparent PNGs and limits me in my bg choice)

我不确定为什么按钮内的 span 元素不会在悬停时触发事件,但您应该只需在按钮本身上查找事件就可以轻松解决该问题。这是演示

另外,我对您的代码进行了一些修改, .wrapInner() 只是为了执行您在脚本开头所做的操作。在这种情况下没有理由使用 .live()

$('#buttons a, #sendbutton1')
.each(function() {
  $(this).wrapInner("<span></span>");
  $(this).children("span").show().css("opacity","0");
})
.bind('mouseover mouseout', function(event) {
  var span = $(this).children('span');
  if (event.type == 'mouseover') {
    // animate opacity to full on mouseover
    span.stop().animate({
      opacity: 1
    }, "slow");
  } else {
    // animate opacity to nill on mouseout
    span.stop().animate({
      opacity: 0
    }, "slow");
  }
});

I'm not sure why the span element inside the button isn't firing an event on hover, but you should easily be able to work around it by just looking for the event on the button itself. Here is a demo!

Also, I've modified your code a bit, .wrapInner() is made just to do what you are doing at the beginning of the script. And there is no reason to use .live() in this situation:

$('#buttons a, #sendbutton1')
.each(function() {
  $(this).wrapInner("<span></span>");
  $(this).children("span").show().css("opacity","0");
})
.bind('mouseover mouseout', function(event) {
  var span = $(this).children('span');
  if (event.type == 'mouseover') {
    // animate opacity to full on mouseover
    span.stop().animate({
      opacity: 1
    }, "slow");
  } else {
    // animate opacity to nill on mouseout
    span.stop().animate({
      opacity: 0
    }, "slow");
  }
});
