我正在尝试编写一个代码,使得一个元素在点击时使用更高的z-index到达前面,我似乎已经想到了,并且我试图使该元素保持不同颜色将其标识为当前页面。我想允许鼠标悬停功能虽然改变其他元素的颜色,以将它们标识为其他按钮,这些元素看起来像文件标签,所以这样看起来更好。不幸的是,我添加了一个javascript代码,以便在单击另一个元素时元素将返回到原始渐变颜色,但我似乎无法弄清楚如何使鼠标悬停功能适用于每个单独的元素。我不知道这对你有意义。
使用Javascript:
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.2.6/jquery.min.js"></script>
<script type="text/javascript">
$(function() {
// Change this selector to find whatever your 'boxes' are
var boxes = $("div.menuitem");
// Set up click handlers for each box
boxes.click(function() {
var el = $(this), // The box that was clicked
max = 0;
// Find the highest z-index
boxes.each(function() {
// Find the current z-index value
var z = parseInt( $( this ).css( "z-index" ), 10 );
// Keep either the current max, or the current z-index, whichever is higher
max = Math.max( max, z );
});
// Set the box that was clicked to the highest z-index plus one
el.css("z-index", max + 1 );
});
});
$(document).ready(function()
{
$("#productmenu").mouseover(function() { $("#productdropdown").css('visibility','visible'); });
$("#productdropdown").mouseover(function() { $("#productdropdown").css('visibility','visible'); });
$("#productdropdown").mouseout(function() { $("#productdropdown").css('visibility','hidden'); });
$("#productmenu").mouseout(function() { $("#productdropdown").css('visibility','hidden'); });
});
$(document).ready(function()
{
$("#productmenu").click(function() { $("#couponmenu").css('background','linear-gradient(0deg, #F90, #D76B00)'); });
$("#productmenu").click(function() { $("#contestmenu").css('background','linear-gradient(0deg, #F90, #D76B00)'); });
$("#productmenu").click(function() { $("#contactmenu").css('background','linear-gradient(0deg, #F90, #D76B00)'); });
$("#couponmenu").click(function() { $("#productmenu").css('background','linear-gradient(0deg, #F90, #D76B00)'); });
$("#couponmenu").click(function() { $("#contestmenu").css('background','linear-gradient(0deg, #F90, #D76B00)'); });
$("#couponmenu").click(function() { $("#contactmenu").css('background','linear-gradient(0deg, #F90, #D76B00)'); });
$("#contestmenu").click(function() { $("#couponmenu").css('background','linear-gradient(0deg, #F90, #D76B00)'); });
$("#contestmenu").click(function() { $("#productmenu").css('background','linear-gradient(0deg, #F90, #D76B00)'); });
$("#contestmenu").click(function() { $("#contactmenu").css('background','linear-gradient(0deg, #F90, #D76B00)'); });
$("#contactmenu").click(function() { $("#productmenu").css('background','linear-gradient(0deg, #F90, #D76B00)'); });
$("#contactmenu").click(function() { $("#contestmenu").css('background','linear-gradient(0deg, #F90, #D76B00)'); });
$("#contactmenu").click(function() { $("#couponmenu").css('background','linear-gradient(0deg, #F90, #D76B00)'); });
})
</script>
我包含了一个像这样的CSS,每个元素,但javascript阻止它工作:
#productmenu:hover {
background:linear-gradient(0deg, #FF972F, #FFD3A8);
z-index:500;
}
HTML:
<a href="#">
<div id="productmenu" class="menuitem" onclick="this.style.background='linear-gradient(0deg, #FF972F, #FFD3A8)',style.zIndex='500';">Products</div>
<ul id="productdropdown">
<li><a href="#">Product 1</a></li>
<li><a href="#">Product 2</a></li>
<li><a href="#">Product 3</a></li>
</ul>
</a>
<a href="#">
<div id="contestmenu" class="menuitem" onclick="this.style.background='linear-gradient(0deg, #FF972F, #FFD3A8)',style.zIndex='500';">Contest</div>
</a>
<a href="#">
<div id="couponmenu" class="menuitem" onclick="this.style.background='linear-gradient(0deg, #FF972F, #FFD3A8)',style.zIndex='500';">Coupon</div>
</a>
<a href="#">
<div id="contactmenu" class="menuitem" onclick="this.style.background='linear-gradient(0deg, #FF972F, #FFD3A8)',style.zIndex='500';">Contact</div>
</a>
答案 0 :(得分:0)
你去男人吧。花了一些时间来弄清楚你想要的是什么。您的HTML和CSS需要一些工作,因为它绝对不符合最佳实践。
我们放弃了<a>
标记,不包裹您的div
。您不应该在将来这样做,因为<a>
元素是内联的,而div
是块。
<强> HTML 强>
<div id="productmenu" class="menuitem"><a>Products</a>
<ul id="productdropdown">
<li><a href="#">Product 1</a></li>
<li><a href="#">Product 2</a></li>
<li><a href="#">Product 3</a></li>
</ul>
</div>
我们还摆脱了很多JavaScript,因为大部分内容可以通过CSS更好地完成,所以我们删除了整个部分:
<强>的JavaScript 强>
$(document).ready(function() {
$("#productmenu").mouseover(function() { $("#productdropdown").css('visibility','visible'); });
$("#productdropdown").mouseover(function() { $("#productdropdown").css('visibility','visible'); });
$("#productdropdown").mouseout(function() { $("#productdropdown").css('visibility','hidden'); });
$("#productmenu").mouseout(function() { $("#productdropdown").css('visibility','hidden'); });
});
整个事情都消失了,因为大多数情况都没有意义。
这是将要接管大部分辛勤工作的CSS:
<强> CSS 强>
[id$=menu]:hover > a,
[id$=menu] li:hover > a {
background:linear-gradient(0deg, #FF972F, #FFD3A8);
}
[id$=menu]:hover ul {
display: block;
list-style: none;
margin: 0;
padding: 0 0 0 20px;
}
[id$=menu] ul {
display: none;
}
[id$=menu] a {
display: block;
}
