在窗口调整大小时销毁Cycle2

标签: javascript jquery window-resize jquery-cycle2

我正在使用http://jquery.malsup.com/cycle2/api/,当我检测到移动设备时,我正试图破坏窗口调整大小事件上的cycle2滑块。不幸的是,它返回以下两个错误:

[cycle2] slideshow must be initialized before sending commands; "destroy" ignored

[cycle2] slideshow must be initialized before sending commands; "reinit" ignored

也许有人可以帮忙,我做错了什么?这是代码:

$(function() {


    var slider = $('.slider').cycle();

    condition = true;

        //destroy onload under condition
    if(condition){
        slider.cycle('destroy');        
    }   

        //destroy on resize 
    $(window).on('resize',function() {              

        condition = true; //Will be function to recondition let´s say it's true by now

        if(condition){

                slider.cycle('destroy');

        } else {            

                slider.cycle('reinit');             

        }

    });

});

谢谢。

看起来你正在破坏这里的滑块:

if(condition){
    slider.cycle('destroy');        
}

你可以这样做:

$(function() {

    var $W = $(window),
        slider = $('.slider').cycle();

    $W.on('resize',function() {              

        if ($W.width() < 768) // width of device 
            slider.cycle('destroy');

    });

});

我知道这是一个老问题,但我也试图解决这个问题,在仔细阅读文档之后,这就是我提出的问题。

所以我使用数据属性在幻灯片上设置我的选项。我非常喜欢这个功能。

为简单起见,这是我打开cycle2 div

<div data-cycle-carousel-visible="3" 
     data-cycle-carousel-fluid="true" 
     data-cycle-fx="carousel" 
     data-cycle-prev="#carousel-prev" 
     data-cycle-next="#carousel-next"
     class="cycle-slideshow cycle-front-page-slideshow"
>

请注意,我确实添加了循环幻灯片类,因此Cycle2自动初始化,然后我还添加了另一类循环前页幻灯片,以防我在我的网站上有其他幻灯片,我可以只针对这一个。< / p>

我的javascript看起来像这样。

function check_window_size( opts ){ 
    // Check if the max-width of window is 899px; window.matchMedia is a native javascript function to check the window size.
    var w899 = window.matchMedia( "(max-width: 899px)" );                               

    // if it is max-width of 899px, then set the number of items in the cycle2 carousel slideshow to 2, else show 3
    // to see if it matches, you would use the variable and grab the matches array; this will return true or false if window size is max-width 899px
    if( w899['matches'] ) {
        opts.carouselVisible = 2;   
    }else{
        opts.carouselVisible = 3;   
    }
}

这是您定位幻灯片的地方(我的使用.cycle-front-page-slideshow类)

// Grab the cycle2 slideshow initialized from the data attributes on the DIV above
$('.cycle-front-page-slideshow').on('cycle-bootstrap', function(e, opts, API) {
    // run the check_window_size function to get initial window size, just in case they are max-width 899px already
    check_window_size( opts );

    // When window is resized, send the options to the check_window_size function so we can manipulate it
    window.onresize = function() {          
        check_window_size( opts );          
    };

});

另请注意,如果您想使用Carousel功能,则必须从http://jquery.malsup.com/cycle2/download/下载cycle2轮播过渡插件

希望这有助于其他人。
