使用 BX-Slider,上一个和下一个箭头填充内部 Divs 以及主 Div
Using BX-Slider, Prev and Next Arrows populate Inner Divs as Well as Main Div
我在每张幻灯片的左侧或右侧制作一个带有一些文本的内框 (div) 时遇到了这个问题。这很容易做,也很时尚,但问题是由于某些原因,上一个箭头和下一个箭头再次将它们自己定位在 secondary/inner div 内,如所附图片所示。
这是示例 html,其中包含与示例图片相对应的幻灯片部分:
<div class="slide" id="slide2">
<div class="band band-right red">
<a href="/why-go-tec/" class="slider" ><h1 class="banner">Your Food Never Tasted This Good</h1></a>
<a href="/why-go-tec/" class="slider" ><h2 class="banner">EXPERIENCE THE 100% INFRARED DIFFERENCE</h2></a>
</div>
</div>
<div class="slide" id="slide3">
<div class="band band-right slate">
<a href="/performance-guarantee/" class="slider" ><h1 class="banner">TEC Owners Love Their Grills</h1></a>
<a href="/performance-guarantee/" class="slider" ><h2 class="banner">WE WANT YOU TO LOVE YOURS TOO - OUR 30-DAY MONEY BACK GUARANTEE</h2></a>
</div>
</div>
我的需要是只显示主 div 两端的两个箭头,并消除显示在较小的纯色矩形内的第二对箭头。
这是我正在处理的页面的link:
BX Slider page
好的,不用担心 WordPress 的怪癖,我会给你一个 Dual Flex-bxSlider 的例子,并介绍重要的部分。
- 两个 div
.bxRight
和 .bxLeft
是 flex 容器 .bxMain
的子元素。这种 flexbox 布局是响应式的,并且有可能改变其他方式,比如堆叠成一列而没有任何 JS/jQuery。我只做了一些基本的 flexbox,如果你想了解更多信息,请访问 here.
- 回到那两个div
.bxRight
和.bxLeft
,它们是两个bxSliders的容器:.mxDisplay
和.txBoard
.bxRight .txBoard
.bxLeft .mxDisplay
我给了 .txBoard
controls: true
和 .mxDisplay
controls: false
,然后使用 bxSlider 的回调,我将 .mxDisplay's
动作从动到 .txBoard's
动作:
- 两个 bxSliders 都有:
onSlideNext: moveBX,
和 onSlidePrev: moveBX,
回调。
所以每次滑动移动都会调用 moveBX():
function moveBX($ele, from, to) {
mx.goToSlide(to);
tx.goToSlide(to);
}
最后一个重要的细节是按钮,现在只有一对可以同时控制两个 bxSliders(从技术上讲不是真的,但肉眼看是这样。)控制按钮的外观和位置,我做了以下操作:
nextSelector: '.bxRBtn',
prevSelector: '.bxLBtn',
nextText: '►',
prevText: '◄'
转至 bx Options 了解完整详情。
该演示在风格上有点原始(匆忙中写的)所以我会把美学留给你。如果这不是您想要的,请告诉我并提供更多详细信息。祝你好运,先生。

在拉动线程球并使用 Firefox 的开发人员检查器查看用于形成和包含 prev-next 箭头的元素名称后,我确定问题出在 jquery.bxslider.js。我注释掉了两行,并更改了 class,我希望将 PREV 和 NEXT 箭头附加到宽 "slide" class(查看以下代码底部附近):
/**
* Appends prev / next controls to the controls element
*/
var appendControls = function(){
//slider.controls.next = $('<a class="bx-next" href="">' + slider.settings.nextText + '</a>');
//slider.controls.prev = $('<a class="bx-prev" href="">' + slider.settings.prevText + '</a>');
slider.controls.next = $('<a class="bx-next" href=""><img src=\"images/next30.png\"></</a>');
slider.controls.prev = $('<a class="bx-prev" href=""><img src=\"images/prev30.png\"></a>');
// bind click actions to the controls
slider.controls.next.bind('click', clickNextBind);
slider.controls.prev.bind('click', clickPrevBind);
// if nextSlector was supplied, populate it
if(slider.settings.nextSelector){
$(slider.settings.nextSelector).append(slider.controls.next);
}
// if prevSlector was supplied, populate it
if(slider.settings.prevSelector){
$(slider.settings.prevSelector).append(slider.controls.prev);
}
// if no custom selectors were supplied
if(!slider.settings.nextSelector && !slider.settings.prevSelector){
// add the controls to the DOM
slider.controls.directionEl = $('<div class="bx-controls-direction" />');
// add the control elements to the directionEl
slider.controls.directionEl.append(slider.controls.prev).append(slider.controls.next);
/* I commented out the following line: */
//slider.viewport.append(slider.controls.directionEl);
/* I ADDED this line. The divs with the class "slide" are the main, wide divs, where I want the arrows to be on either end: */
$(".slide").append(slider.controls.directionEl);
/* I commented out the following line: */
//slider.controls.el.addClass('bx-has-controls-direction').append(slider.controls.directionEl);
}
}
我还要做的一件事是 fiddle 箭头的垂直定位,这样它们就不会与垂直居中的文本重叠,但更重要的是,我添加了一个高 z-index
到 bx-prev 和 bx-next classes,这样箭头将始终显示在最顶层,而不是隐藏在我放置在幻灯片中的任何次要矩形下:
a.bx-prev{
position:absolute;
top:100%;
margin-top:-35px;
left:10px;
margin-left:0px;
z-index:10;
}
a.bx-next{
position:absolute;
top:100%;
margin-top:-35px;
left:100%;
margin-left:-40px;
z-index:10;
}
