jQuery Slider 执行异常?
经过许多教程和大量时间后,我成功地使用 jQuery 构建了一个滑块。然而,它的工作并不像我希望的那么顺利。我使用了自定义句柄,由于新的 jQueryUI 没有句柄选项,我在 CSS 中创建了一个句柄。然而,这个手柄超出了滑块所需的范围。我已经上传了一个测试页面,可以在此处找到。
我的代码如下:
CSS
<style type="text/css" media="screen">
<!--
body {
padding: 0;
font: 1em "Trebuchet MS", verdana, arial, sans-serif;
font-size: 100%;
background-color: #212121;
margin: 0;
}
h1 {
margin-bottom: 2px;
}
#container {
background-color: #fff;
width: 580px;
margin: 15px auto;
padding: 50px;
}
/* slider specific CSS */
.sliderGallery {
background: url(productbrowser_background_20070622.jpg) no-repeat;
overflow: hidden;
position: relative;
padding: 10px;
height: 160px;
width: 560px;
}
.sliderGallery UL {
position: absolute;
list-style: none;
overflow: none;
white-space: nowrap;
padding: 0;
margin: 0;
}
.sliderGallery UL LI {
display: inline;
}
.slider {
width: 542px;

margin-top: 140px;
margin-left: 5px;

margin-left:-90px;

z-index: 100;
}
.slider span {

z-index: 110;

我想知道是否有任何方法可以强制滑块停留在其后面的图像内?如果我没有解释清楚的话,测试链接会让你明白我的意思。

I have, after many tutorials and lots of time, managed to build a slider with jQuery. However, it's not working as smoothly as I would have hoped. I have used a custom handle, and seeing as the new jQueryUI doesn't have a handle option, I have created a handle in CSS. However, this handle is going beyond the required bounds of the slider. I have uploaded a test page which can be found here.
My code is as follows:
CSS
<style type="text/css" media="screen">
<!--
body {
padding: 0;
font: 1em "Trebuchet MS", verdana, arial, sans-serif;
font-size: 100%;
background-color: #212121;
margin: 0;
}
h1 {
margin-bottom: 2px;
}
#container {
background-color: #fff;
width: 580px;
margin: 15px auto;
padding: 50px;
}
/* slider specific CSS */
.sliderGallery {
background: url(productbrowser_background_20070622.jpg) no-repeat;
overflow: hidden;
position: relative;
padding: 10px;
height: 160px;
width: 560px;
}
.sliderGallery UL {
position: absolute;
list-style: none;
overflow: none;
white-space: nowrap;
padding: 0;
margin: 0;
}
.sliderGallery UL LI {
display: inline;
}
.slider {
width: 542px;
height: 17px;
margin-top: 140px;
margin-left: 5px;
padding: 1px;
position: relative;
background: url(productbrowser_scrollbar_20070622.png) no-repeat;
}
.ui-slider .ui-slider-handle {
width:180px;
margin-left:-90px;
}
.ui-slider-handle {
position: absolute;
cursor: default;
height: 17px;
top: 0;
background: url(productbrowser_scroller_20080115.png) no-repeat;
z-index: 100;
}
.slider span {
color: #bbb;
font-size: 80%;
cursor: pointer;
position: absolute;
z-index: 110;

.slider .slider-lbl1 {

.slider .slider-lbl2 {

}
.slider .slider-lbl3 {
left: 156px;

<div class="slider ui-slider">
<div class="handle"></div>
<span class="slider-lbl1">Our Books</span>
<span class="slider-lbl2">Other Books</span>
</div>

</div>
What I'd like to know is if there is any way to force the slider bar to stay inside the image behind it? The test link will let you understand what I mean if I didn't explain myself clearly.
Thanks in advance,

问题在于您的句柄设置为超出其容器这一事实。
这两个问题来自以下内容
第二行表示允许滑块在其初始容器的左侧之前移动 90px(因此左侧溢出)
并且当将手柄的左侧设置为 100% 时,这意味着它将从 90 像素 (180-90) 溢出到右侧。
我处理这个问题的方法是删除
margin-left:-90px;
,将滚动 div 的宽度减少 180px 并使用另一个 div 来显示滚动条图像(位于你的滑动div,但更宽)。像这样的东西:
编辑: 要回答您的评论,对页面上的 CSS 进行以下更正应该可以实现:
此组合将使其具有相同的边界 (-90 + 90 = 0 ),但会让它移动得很好。
编辑2:
要启用手柄上的点击,您需要指定
手柄
的高度(否则您将无法点击它)。然而,这会将您的跨度移动到滑动 div 下方,要克服它,您必须指定它们的顶部位置(因为您已经将它们绝对化了,所以很容易;)
)。应该做以下事情。
为了使其在跨度之上工作,您需要像这样更改您的 html:
The problem is coming from the fact that your handle is set to go outside of it's container.
The two problems are coming from the following
The second line says that the slider is allowed to go 90px before the left of it's initial container (hence the left overflow)
And when setting the left of the handle to 100%, it means that it will overflow on the right from 90px (180-90).
The way I would handle that would be to drop the
margin-left:-90px;
, to reduce the width of the scrolling div by 180px and to use another div to display the scroll bar image (positioned under your sliding div, but wider).Something like:
EDIT: To answer to your comment, the following correction to the CSS on your page should make that work:
This combination will let it with the same boundaries (-90 + 90 = 0 ) but are going to make it move nicely.
EDIT2:
TO enable the click on the handle, you'll need to specify a height to your
handle
(otherwise you wouldn't be able to click on it). However this will move your span under the sliding div, to overcome it you'll have to specify their top position (as you already have them in absolute it's easy;)
).The following should do.
To make that work above the span, you'll need to change your html a bit like that:
