Particle Tree 最近发布了一篇文章描述了一种他们拿出的设计按钮元素的技术,对于那些不熟练的人来说,表格按键是出了名的难以定制。典型的解决方案是使用浏览器提供的默认按钮,或者是使用一个图形输入。当图形输入完成了需求结果时,它请求创建一个新的图形为每一个按钮用它的文本“Baked-in”(没有提及以hovers交换它)。

尽管Particle Tree的技术提供了一种可靠的方案,它不能满足我们的需求。我们需要一种使用了滑动门技术的按钮,一种真正的HTML文本,不需要请求JavaScript转滚或者提交表格。满足这些条件就意味着input和anchor元素被排除了。很显然,按钮元素正是我们唯一的选择。下面的技术示范了一种使用滑动门技术的跨浏览器的按钮的技术。

标签:
复制代码 代码如下:

<button value="submit" class="submitBtn"><span>Submit</span></button>

CSS:

程序代码
复制代码 代码如下:

button {
border:0;
cursor:pointer;
font-weight:bold;
padding:0 20px 0 0;
text-align:center;
}
button span {
position:relative;
display:block;
white-space:nowrap;
padding:0 0 0 20px;
}
/*blue buttons*/
button.submitBtn {
background:url(images/btn_blue_right.gif) right no-repeat;
font-size:1.3em;
}
button.submitBtn span {
height:50px;
line-height:50px;
background:url(images/btn_blue_left.gif) left no-repeat;
color:#fff;
}
button.submitBtn:hover {
background:url(images/btn_blue_right_hover.gif) right no-repeat;
}
button.submitBtn:hover span {
background:url(images/btn_blue_left_hover.gif) left no-repeat;
}

CSS For IE6和IE7(有时候需要)

复制代码 代码如下:

button {
width:auto;
overflow:visible;
}
button span {
margin-top:1px;
}

就像你能看到的那样,每个状态使用了2个图片(总共4个图片)。进一步简化,可以将这些状态转化为两个。但这种想法的最初测试出现了不一致的结果。

浏览器支持:
IE6,IE7,Firefox(mac/pc),Safari,Opera,Camino等等。

警告:为了使hover在IE6中有效,你将需要编写一个类触发器。尽管不像图片交换一样糟糕。
