查找当前幻灯片并将Class添加到父div [英] Find current Slide and add Class to parent div
问题描述
我正在尝试在自动播放时将类添加到当前滑块的父div,我正在使用 Jssor Slider .
I'm trying to add Class to Current Slider parent div when auto-play, I am using Jssor Slider.
致电Jassor:
jQuery(document).ready(function($) {
//Define an array of slideshow transition code
var _SlideshowTransitions = [
{$Duration:1200,x:1,$Delay:40,$Cols:6,$Formation:$JssorSlideshowFormations$.$FormationStraight,$Easing:{$Left:$Jease$.$InOutQuart,$Opacity:$Jease$.$Linear},$Opacity:2,$ZIndex:-10,$Brother:{$Duration:1200,x:1,$Delay:40,$Cols:6,$Formation:$JssorSlideshowFormations$.$FormationStraight,$Easing:{$Top:$Jease$.$InOutQuart,$Opacity:$Jease$.$Linear},$Opacity:2,$ZIndex:-10,$Shift:-100}},
{$Duration:1200,y:0.3,$Cols:2,$During:{$Top:[0.3,0.7]},$ChessMode:{$Column:12},$Easing:{$Top:$Jease$.$InCubic,$Opacity:$Jease$.$Linear},$Opacity:2},
{$Duration:1200,x:0.3,$Rows:2,$During:{$Left:[0.3,0.7]},$ChessMode:{$Row:3},$Easing:{$Left:$Jease$.$InCubic,$Opacity:$Jease$.$Linear},$Opacity:2}
];
var options = {
$AutoPlay: true,
$PauseOnHover: 1, //[Optional] Whether to pause when mouse over if a slideshow is auto playing, default value is false
$ArrowKeyNavigation: true, //Allows arrow key to navigate or not
$SlideWidth: 800, //[Optional] Width of every slide in pixels, the default is width of 'slides' container
//$SlideHeight: 300, //[Optional] Height of every slide in pixels, the default is width of 'slides' container
$SlideSpacing: 0, //Space between each slide in pixels
$Cols: 1, //Number of pieces to display (the slideshow would be disabled if the value is set to greater than 1), the default value is 1
//New add for random transition
$SlideshowOptions: {
$Class: $JssorSlideshowRunner$,
$Transitions: _SlideshowTransitions,
$TransitionsOrder: 0, //The way to choose transition to play slideshow, 1: Sequence, 0: Random
$ShowLink: true
},
$ArrowNavigatorOptions: { //[Optional] Options to specify and enable arrow navigator or not
$Class: $JssorArrowNavigator$, //[Requried] Class to create arrow navigator instance
$ChanceToShow: 2, //[Required] 0 Never, 1 Mouse Over, 2 Always
$Steps: 1 //[Optional] Steps to go for each navigation request, default value is 1
}
};
var jssor_slider1 = new $JssorSlider$("slider1_container", options);
//responsive code begin
//you can remove responsive code if you don't want the slider scales while window resizes
function ScaleSlider() {
var parentWidth = jssor_slider1.$Elmt.parentNode.clientWidth;
if (parentWidth)
jssor_slider1.$ScaleWidth(Math.min(parentWidth, 800));
else
window.setTimeout(ScaleSlider, 30);
}
ScaleSlider();
$(window).bind("load", ScaleSlider);
$(window).bind("resize", ScaleSlider);
$(window).bind("orientationchange", ScaleSlider);
}); // Call end
HTML:
<div id="slider1_container" style="position: relative; top: 0px; left: 0px; width: 800px;height: 300px; overflow: hidden;">
<!-- Slides Container -->
<div u="slides" style="cursor: move; position: absolute; left: 0px; top: 0px; width: 800px; height: 300px;overflow: hidden;">
<div><img u="image" src="http://www.jssor.com/img/photography/002.jpg"/></div>
<div><img u="image" src="http://www.jssor.com/img/photography/003.jpg"/></div>
<div><img u="image" src="http://www.jssor.com/img/photography/003.jpg"/></div>
<div><img u="image" src="http://www.jssor.com/img/photography/005.jpg"/></div>
</div>
</div>
我尝试给定JS:
// event fired when slider is "parked"
jssor_slider1.$On( $JssorSlider$.$EVT_PARK, function(slideIndex){
var allImages = $(jssor_slider1.$Elmt).find("img[u=image]");
var currentImage = allImages.eq(slideIndex);
var currentDiv = currentImage.parent("div");
currentDiv.addClass("current");
});
// event fired when slider starts moving
jssor_slider1.$On( $JssorSlider$.$EVT_POSITION_CHANGE, function(position){
// remove 'current' class from all slides
$(jssor_slider1.$Elmt).find(".current").removeClass("current");
});

通过此js,它可以在没有自动播放的情况下正常工作,但是当滑块自动播放无法正常工作时,如何解决此建议?
预先感谢.

By this js it's works without auto-play, but when slider auto-play it's unable to work, how to fix this any suggestions?
Thanks in advance.
推荐答案
在您的html代码中,将类名称 current 赋予第一个div(幻灯片容器div),如下所示:
in your html code give class name current to first div (slide container div) like code given below
<div class="current" id="slider1_container" style="position: relative; top: 0px; left: 0px; width: 800px;height: 300px; overflow: hidden;">
尝试并让我知道是否可行,我认为您想要做的事.
try and let me know if that works, i think that what u wanted do.
