Javascript 在单击按钮时动态设置jssor滑块的自动播放属性

您好，我正在我的应用程序中集成jssor滑块。我使用了一个基本版本的滑块来显示一组图像，用户可以从右向左滑动

 /* Gallery items carousel slider - start */
    var options = {
        $StartIndex: 0,                 //[Optional] Index of slide to display when initialize, default value is 0

        $AutoPlay: false,                                    //[Optional] Whether to auto play, to enable slideshow, this option must be set to true, default value is false
        $AutoPlaySteps: 1,                                  //[Optional] Steps to go for each navigation request (this options applys only when slideshow disabled), the default value is 1
        $AutoPlayInterval: 4000,                            //[Optional] Interval (in milliseconds) to go for next slide since the previous stopped if the slider is auto playing, default value is 3000
        $PauseOnHover: 3,                               //[Optional] Whether to pause when mouse over if a slider is auto playing, 0 no pause, 1 pause for desktop, 2 pause for touch device, 3 pause for desktop and touch device, 4 freeze for desktop, 8 freeze for touch device, 12 freeze for desktop and touch device, default value is 1
        $Loop: 0,                                      // Enable loop(circular) of carousel or not, 0: stop, 1: loop, 2 rewind, default value is 1
        $ArrowKeyNavigation: true,                          //[Optional] Allows keyboard (arrow key) navigation or not, default value is false
        $SlideDuration: 500,                                //[Optional] Specifies default duration (swipe) for slide in milliseconds, default value is 500
        $MinDragOffsetToSlide: 20,                          //[Optional] Minimum drag offset to trigger slide , default value is 20
        //$SlideWidth: 600,                                 //[Optional] Width of every slide in pixels, default value is width of 'slides' container
        //$SlideHeight: 300,                                //[Optional] Height of every slide in pixels, default value is height of 'slides' container
        $SlideSpacing: 5,                                   //[Optional] Space between each slide in pixels, default value is 0
        $Cols: 1,                                  //[Optional] Number of pieces to display (the slideshow would be disabled if the value is set to greater than 1), the default value is 1
        $Align: 0,                                //[Optional] The offset position to park slide (this options applys only when slideshow disabled), default value is 0.
        $UISearchMode: 1,                                   //[Optional] The way (0 parellel, 1 recursive, default value is 1) to search UI components (slides container, loading screen, navigator container, arrow navigator container, thumbnail navigator container etc).
        $PlayOrientation: 1,                                //[Optional] Orientation to play slide (for auto play, navigation), 1 horizental, 2 vertical, 5 horizental reverse, 6 vertical reverse, default value is 1
        $DragOrientation: 1,                                //[Optional] Orientation to drag slide, 0 no drag, 1 horizental, 2 vertical, 3 either, default value is 1 (Note that the $DragOrientation should be the same as $PlayOrientation when $DisplayPieces is greater than 1, or parking position is not 0)

        $ThumbnailNavigatorOptions: {
            $Class: $JssorThumbnailNavigator$,              //[Required] Class to create thumbnail navigator instance
            $ChanceToShow: 2,                               //[Required] 0 Never, 1 Mouse Over, 2 Always
            $ActionMode: 1,                                 //[Optional] 0 None, 1 act by click, 2 act by mouse hover, 3 both, default value is 1
            $AutoCenter: 3,                             //[Optional] Auto center thumbnail items in the thumbnail navigator container, 0 None, 1 Horizontal, 2 Vertical, 3 Both, default value is 3
            $Lanes: 1,                                      //[Optional] Specify lanes to arrange thumbnails, default value is 1
            $SpacingX: 1,                                   //[Optional] Horizontal space between each thumbnail in pixel, default value is 0
            $SpacingY: 0,                                   //[Optional] Vertical space between each thumbnail in pixel, default value is 0
            $DisplayPieces: 5,                              //[Optional] Number of pieces to display, default value is 1
            $ParkingPosition: 0,                            //[Optional] The offset position to park thumbnail
            $Orientation: 1,                                //[Optional] Orientation to arrange thumbnails, 1 horizental, 2 vertical, default value is 1
            $DisableDrag: true                              //[Optional] Disable drag or not, default value is false
        }
    };
    var arrImg = ["01.jpg", "02.jpg", "03.jpg", "04.jpg"];

    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) {
            var sliderWidth = parentWidth;

            //keep the slider width no more than 600
            sliderWidth = Math.min(sliderWidth, 600);

            jssor_slider1.$ScaleWidth(sliderWidth);
        }
        else
            window.setTimeout(ScaleSlider, 30);
    }
    ScaleSlider();

    $(window).bind("load", ScaleSlider);
    $(window).bind("resize", ScaleSlider);

$(window).bind("orientationchange", ScaleSlider);

1） 我有一个按钮在我的页面上点击，我需要设置这个滑块的自动播放属性设置为真，以启用图像自动滚动。再次点击它应该会停止jssor滑块的自动播放

$('.StartSlideshowBtn')
    .click(
            function () {
                slider1_container
                if (options.$AutoPlay == false) {
                    options.$AutoPlay = true;
                }
                else {
                    options.$AutoPlay = false;
                }
                jssor_slider1 = new $JssorSlider$("slider1_container", options);

                        });

我尝试设置它，但无法访问其中jssor滑块的对象。

任何帮助都将不胜感激。

非常感谢，你救了我一天。它工作得很好。但出于好奇，我有一件事要问。我尝试了代码片段var sliderObj=document.getElementById（“slider1_容器”）；log（“幻灯片自动播放为”+sliderObj.$AUTOPLAY）；如果（sliderObj.$AutoPlay==false）{sliderObj.$AutoPlay=true；}否则{sliderObj..$AutoPlay=false；}这段代码可以工作吗？您不能从sliderObj.$AutoPlay读取任何内容。正确的调用是sliderObj。$IsAutoPlaying（）我需要从数据库加载带有图像的slider，当图像在slideshow中滚动时，我应该为特定图像更新下面的标签。您能告诉我任何事件，我可以使用它来为每个图像上的标签赋值吗。像任何随着滑块索引更改而触发的事件一样？感谢当幻灯片索引改变时，$EVT_公园将启动。
