JQuery幻灯片，带有可点击的编号位置

时间：2015-04-07 13:59:28

标签： javascript jquery html css

好吧，我有一些问题，我正在制作我自己的Jquery幻灯片，包括播放，暂停，下一个和上一个按钮。我想制作带有编号图像当前编号的幻灯片，并且可点击以便编号为4的图像，但我想要点击数字2。 我在谷歌和这个网站上搜索，但很难找到，因为使用Jquery插件有很多可供参考，但我正在学习Jquery，所以我没有使用插件。

他们是否必须使用数组对图像进行排序，并且他们有数字列表？

无论如何这是我的代码。 HTML：

<html>
<head>
    <title>Slideshow - Menggunakan Jquery</title>
    <link rel="stylesheet" type="text/css" href="style.css">
    <script src="jquery-2.1.3.js"></script>
</head>
<body>
<div id='items'>
    <ul>
        <li class='item first'><img src="raisa1.jpg"/></li>
        <li class='item'><img src="raisa2.jpg"/></li>
        <li class='item'><img src="raisa3.jpg"/></li>
    </ul>
</div>
<ul id='controls'>
    <button id='prev'>Prev</button>
    <button id='play'>Play</button>
    <button id='pause'>Pause</button>
    <button id='next'>Next</button>
</ul>
</body>
<script src="slideshow.js"></script>
</html>

CSS：

#items {
    position : relative;
    width : 400px;
    height : 200px;
    top : 20px;
    left : 20px;
}
.item {
    position : absolute;
    background-color : #eee;
    border : 1px solid #ccc;
    width : 398px;
    height : 198px;
    display :none;
    text-align : center;
    font-size : 72px;
}

.item img{
    text-align: center;
    display: block;
    max-width:398px;
    max-height: 198px;
    width: auto;
    height: auto;
    margin: auto;
}

.first{
    display : block;
}
#controls {
    margin-top : 30px;
}
li {
    display : inline-block;
    padding : 5px;
    border : 1px solid #ccc;
    background-color : #eee;
    cursor : pointer;
}
#play {
    display : none;
}

Jquery的：

var timeoutId;
var slideImage = function( step ) {
    if ( step == undefined ) step = 1;
    //Clear timeout if any
    clearTimeout ( timeoutId );
    //Get current image's index
    var indx = $('.item:visible').index('.item');
    //If step == 0, we don't need to do any fadein our fadeout
    if ( step != 0 ) {
       //Fadeout this item
       $('.item:visible').fadeOut();
    }
    //Increment for next item
    indx = indx + step ;
    //Check bounds for next item
    if ( indx >= $('.item').length ) {
        indx = 0;
    } else if ( indx < 0 ) {
        indx = $('.item').length - 1;
    }
    //If step == 0, we don't need to do any fadein our fadeout
    if ( step != 0 ) {
       //Fadein next item
       $('.item:eq(' + indx + ')').fadeIn();
    }
    //Set Itmeout
    timeoutId = setTimeout ( slideImage, 5000 );
};
//Start sliding
slideImage(0);
//When clicked on prev
$('#prev').click(function() {
    //slideImage with step = -1
    slideImage (-1);   
});
//When clicked on next
$('#next').click(function() {   
     //slideImage with step = 1
     slideImage (1);
});               
//When clicked on Pause
$('#pause').click(function() {
   //Clear timeout
   clearTimeout ( timeoutId );    
    //Hide Pause and show Play
    $(this).hide();
    $('#play').show();
});
//When clicked on Play
$('#play').click(function() {
   //Start slide image
   slideImage(0);
   //Hide Play and show Pause
   $(this).hide();
   $('#pause').show();
});
$(document).ready(function(){
   var sliderwidth = 500;
  $('#navigation li').bind('click',function() {
   $('.slider').animate({left:"-" + sliderwidth * $(this).index() },1000);
  });
});

我添加了

  • 每张图片的ID
  • 当前显示图片的全局变量
  • 将在点击链接时调用的函数，该函数将调用您的函数slideImage

JSFiddle：http://jsfiddle.net/p0gdopha/ 

//To store timeout id
var timeoutId,
    currImg = 1;

var slideImage = function( step ) {

  if ( step == undefined ) step = 1;

  //Clear timeout if any
  clearTimeout ( timeoutId );

  //Get current image's index
  var indx = $('.item:visible').index('.item');

  //If step == 0, we don't need to do any fadein our fadeout
  if ( step != 0 ) {
    //Fadeout this item
    $('.item:visible').fadeOut();
  }

  //Increment for next item
  indx = indx + step ;

  //Check bounds for next item
  if ( indx >= $('.item').length ) {
    indx = 0;
  } else if ( indx < 0 ) {
    indx = $('.item').length - 1;
  }

  //If step == 0, we don't need to do any fadein our fadeout
  if ( step != 0 ) {
    //Fadein next item
    $('.item:eq(' + indx + ')').fadeIn();
    currImg = $('.item:eq(' + indx + ')').attr('id');
  }

  //Set Itmeout
  timeoutId = setTimeout ( slideImage, 5000 );
};

//Start sliding
slideImage(0);

//When clicked on prev
$('#prev').click(function() {

  //slideImage with step = -1
  slideImage (-1);   
});

//When clicked on next
$('#next').click(function() {

  //slideImage with step = 1
  slideImage (1);
});

//When clicked on Pause
$('#pause').click(function() {

  //Clear timeout
  clearTimeout ( timeoutId );    

  //Hide Pause and show Play
  $(this).hide();
  $('#play').show();
});

//When clicked on Play
$('#play').click(function() {

  //Start slide image
  slideImage(0);

  //Hide Play and show Pause
  $(this).hide();
  $('#pause').show();
});

$('a').click(function(ev){
    ev.preventDefault();
    console.log(currImg + ' | ' + $(this).attr('href'));
    slideImage($(this).attr('href') - currImg);
});

$(document).ready(function(){
  var sliderwidth = 500;
  $('#navigation li').bind('click',function() {
    $('.slider').animate({left:"-" + sliderwidth * $(this).index() },1000);
  });
