我的 jquery 滑块刷新率不会实时更新

Question

我正在尝试开发一个简单的 jquery 滑块，滑块默认每三秒在图像和文本之间切换一次 (var segundos = 3;)，滑块有一个按钮，用作 play/pause 动作和一个菜单选项，可让您增加或减少每次在图像之间切换的秒数。这是通过类 .resta 和 .suma（减少和减少）完成的。

现在，滑块工作正常但有一个问题，当 segundos 变量（segundos 表示秒）改变效果不采取行动，除非滑块暂停，它不会自动刷新，而 theslider 运行。它必须像这样：暂停滑块 > 更改默认秒数 > 播放滑块 > 查看结果

我的 objective 是为了在滑块向上和运行.

时改变刷新率

代码如下：

<script>
$(document).ready(function(){
    var segundos = 3000;
    var stop = true;
    var slideInterval;

 
 $('.play').click(function(){
    if (stop == false) {
    stop = true;
 $('#playpause').text('Play it');
    clearInterval(slideInterval);
    }
    else {
    stop = false;
 $('#playpause').text('Pause it');
    slideInterval = setInterval(swapSlides, segundos);
    }
    });
 
 
    function swapSlides(){
 //var cs = $('div.currentslide:first');
 var cs = $('#polaroid1').children('.currentslide:first');
 var ns = cs.next();
 if(ns.hasClass('mySlides1')){
 cs.removeClass('currentslide');
 ns.addClass('currentslide');
    }
 else{
 ns = $('#polaroid1').children('div.mySlides1:first');
 cs.removeClass('currentslide');
 ns.addClass('currentslide');
 }
 }
 
 
    $('.resta').click(function(){
    if(segundos > 1000){
    segundos = segundos - 1000;
 segundoss = (segundos/1000);
    $('.segundos').text(" " + segundoss + "s ");
    }
    });

    $('.suma').click(function(){
    if(segundos >= 1000 && segundos < 15000){
    segundos = segundos + 1000;
 segundoss = (segundos/1000);
    $('.segundos').text(" " + segundoss + "s ");
    }
    });
 
});
</script>

Answer 1

It has to go like this: pause slider > change default seconds > play slider > see results

My objective is to make it so it changes the refresh rate while the slider is up and running.

那是因为当您 increase/decrease 幻灯片间隔时间 (segundos) 时，您从未对 slideInterval 做任何事情。

解法：

添加功能以重新启动您的 slideInterval，如下所示：

 function _restartSlide() {     
      clearInterval(slideInterval);
      slideInterval = setInterval(swapSlides, segundos);   
 }
