随机图像滑块(JS)

我有一个图像滑块。

不幸的是, 图像滑块卡在第二张图像上。

我希望图像滑块在无限随机循环中循环显示图像。

我该怎么做?

这是我的jsfiddle:

JS代码

$(document).ready(function() {

//$('.slider #1').show({right:'0'}, 500);
$('.slider #1').show('slide',{direction:'right'},500);
$('.slider #1').delay(5500).hide('slide',{direction:'left'},500);

var sliderTotalImg = $('.slider img').size();    
var counterIndex = 2;

setInterval(function () {

    //$('.slider #' + counterIndex).show({right:'0'}, 500);
    $('.slider #' + counterIndex).show('slide',{direction:'right'},500);
    $('.slider #' + counterIndex).delay(5500).hide('slide',{direction:'left'},500);

    if(count==slidecount){
count=1;

}else{
count=count+1;
}
},6500);});

您永远不会定义slidecount。它仅在您的if语句中使用。你永远不会定义count。它的第一次使用是在if语句中。

我不确定您是否这样做,但您可以观看控制台输出(键盘快捷键 F12 )以查看代码中发生的错误。在原始代码中,错误是count未定义。它只显示第一个错误,因此在您使用slidecount修复错误后,它会显示count错误。

注意:您的代码中没有任何内容是随机的。所以,我不确定你打算随意做什么。

以下内容适用(JSFiddle):

$(document).ready(function() {

  //$('.slider #1').show({right:'0'}, 500);
  $('.slider #1').show('slide', {
    direction: 'right'
  }, 500);
  $('.slider #1').delay(5500).hide('slide', {
    direction: 'left'
  }, 500);

  var sliderTotalImg = $('.slider img').size();
  var counterIndex = 2;
  var slidecount = 4;

  setInterval(function() {

    //$('.slider #' + counterIndex).show({right:'0'}, 500);
    $('.slider #' + counterIndex).show('slide', {
      direction: 'right'
    }, 500);
    $('.slider #' + counterIndex).delay(5500).hide('slide', {
      direction: 'left'
    }, 500);

    if (counterIndex >= slidecount) {
      counterIndex = 1;

    } else {
      counterIndex++;
    }
  }, 6500);
});
.slider {
  width: 20%;
  height: 30%;
  overflow: hidden;
  border: 1px solid black;
  background-image: url("http://test.softvex.com/Slider/Img/loading.gif");
  background-repeat: no-repeat;
  background-position: center;
}
.slider img {
  display: none;
}
