使用 Jquery(圆周运动)更改图像 [英] Change images using Jquery (Circular motion)

问题描述

大家好，

我有一个这样的 DOM

<div class="GaleryLeftPanel"><img id="img1" src="/Content/Public/images/1.png" style="z-index: 100" width="141"height="140" alt="图像 1"/></div><div class="GalleryMiddlePanel"><img id="img2" src="/Content/Public/images/3.png" style="z-index: 99" width="715"height="497" alt="图像 2"/></div><div class="GaleryRightPanel"><img id="img3" src="/Content/Public/images/2.png" style="z-index: 98" width="140"height="140" alt="图像 2"/></div>

我需要的是，如果我点击img1，img2被替换成img1，而img3被替换成img2和img1 替换为 img3(圆周运动 1->2, 2->3, 3->1).它是连续的......如果我点击 img3 那么它是反向的 (1<-2, 2<-3, 3<-1).

为此，我使用 JQuery 如下:

$('img#img1').click(function () {var currentScr = $(this).attr('src');var second = $('img#img2').attr('src');var 第三 = $('img#img3').attr('src');$('img#img3').attr('src', second);$('img#img2').attr('src', currentScr);$('img#img1').attr('src', 第三个);});$('img#img3').click(function () {var 第三 = $(this).attr('src');var first = $('img#img1').attr('src');var second = $('img#img2').attr('src');$('img#img2').attr('src', 第三个);$('img#img3').attr('src', first);$('img#img1').attr('src', second);});

一切正常.现在，我需要的是，始终将第二张图像替换为大图像而不是原始图像...例如:

点击 img1(1->2L、2->3、3->1).这里2L是img1的大图.和点击 img3 (1<-2, 2L<-3, 3<-1).这里2L是img3的大图

如何做到这一点?，请帮帮我

解决方案

这里您需要的是使用双端队列数据结构，以便您可以遍历图像.

这是一个工作演示 - 如果你给我我可以制作的大图像的 URL它按您的描述工作.

这是代码:

var imgs = new Array();imgs[0] = 'http://farm7.staticflickr.com/6198/6145108610_a5d456dae4_t.jpg';imgs[1] = 'http://farm3.staticflickr.com/2564/4064894944_34b0460fc2_t.jpg';imgs[2] = 'http://farm1.staticflickr.com/178/460793430_1c0a085849_t.jpg';$('#img1').click(function () {$('#img1').attr('src', imgs[2]);$('#img2').attr('src', imgs[0]);//- 在这里做一些事情来使用更大版本的图像$('#img3').attr('src', imgs[1]);imgs.unshift(imgs.pop());});$('#img3').click(function () {$('#img1').attr('src', imgs[1]);$('#img2').attr('src', imgs[2]);//- 在这里做一些事情来使用更大版本的图像$('#img3').attr('src', imgs[0]);imgs.push(imgs.shift());});

还有一个稍微重构的版本这里.

这是带有大图的版本.

var imgs = new Array();imgs[0] = {small: 'http://farm7.staticflickr.com/6198/6145108610_a5d456dae4_t.jpg',大:'http://farm7.staticflickr.com/6198/6145108610_a5d456dae4_b.jpg'}；imgs[1] = {small: 'http://farm3.staticflickr.com/2564/4064894944_34b0460fc2_t.jpg',大:'http://farm3.staticflickr.com/2564/4064894944_34b0460fc2_b.jpg'}；imgs[2] = {小:'http://farm9.staticflickr.com/8201/8219867682_7c9aea748f_t.jpg'，大:'http://farm9.staticflickr.com/8201/8219867682_7c9aea748f_b.jpg'}；var $img1 = $('#img1');var $img2 = $('#img2');var $img3 = $('#img3');$img1.click(function () {$img1.attr('src', imgs[2].small);$img2.attr('src', imgs[0].big);$img3.attr('src', imgs[1].small);imgs.unshift(imgs.pop());});$img3.click(function () {$img1.attr('src', imgs[1].small);$img2.attr('src', imgs[2].big);$img3.attr('src', imgs[0].small);imgs.push(imgs.shift());});

Good day guys,

I've a DOM like this

<div class="Gallery">
  <div class="GaleryLeftPanel">
     <img id="img1" src="/Content/Public/images/1.png" style="z-index: 100" width="141"
                            height="140" alt="image 1" /></div>
   <div class="GalleryMiddlePanel">
      <img id="img2" src="/Content/Public/images/3.png" style="z-index: 99" width="715"
                            height="497" alt="image 2" /></div>
   <div class="GaleryRightPanel">
      <img id="img3" src="/Content/Public/images/2.png" style="z-index: 98" width="140"
                            height="140" alt="image 2" /></div>
 </div>

What I need is, If I click on img1, img2 is replaced with img1, and img3 is replaced with img2 and img1 is replaced with img3 (circular motion 1->2, 2->3, 3->1). and it continuous... and if I click on img3 then it's reverse (1<-2, 2<-3, 3<-1).

for this I'm using JQuery as follows:

$('img#img1').click(function () {
        var currentScr = $(this).attr('src');
        var second = $('img#img2').attr('src');
        var third = $('img#img3').attr('src');

        $('img#img3').attr('src', second);
        $('img#img2').attr('src', currentScr);
        $('img#img1').attr('src', third);
    });

    $('img#img3').click(function () {
        var third = $(this).attr('src');
        var first = $('img#img1').attr('src');
        var second = $('img#img2').attr('src');

        $('img#img2').attr('src', third);
        $('img#img3').attr('src', first);
        $('img#img1').attr('src', second);
    });

It's working fine. now, What I need is, Always the 2nd image should be replace with large image instead of original image... say for example:

click on img1 (1->2L, 2->3, 3->1). here 2L is large image of img1. and click on img3 (1<-2, 2L<-3, 3<-1). here 2L is large image of img3

How to do this?, Please help me

解决方案

What you need here is to use a double ended queue data structure so you can loop through the images.

Here's a working demo - if you give me URLs to the big images I can make it work as you described.

And here's the code:

var imgs = new Array();
imgs[0] = 'http://farm7.staticflickr.com/6198/6145108610_a5d456dae4_t.jpg';
imgs[1] = 'http://farm3.staticflickr.com/2564/4064894944_34b0460fc2_t.jpg';
imgs[2] = 'http://farm1.staticflickr.com/178/460793430_1c0a085849_t.jpg';

$('#img1').click(function () {
        $('#img1').attr('src', imgs[2]);
        $('#img2').attr('src', imgs[0]); // - Do something here to use a larger version of the image
        $('#img3').attr('src', imgs[1]);
        imgs.unshift(imgs.pop());
    });

    $('#img3').click(function () {
        $('#img1').attr('src', imgs[1]);
        $('#img2').attr('src', imgs[2]); // - Do something here to use a larger version of the image
        $('#img3').attr('src', imgs[0]);
        imgs.push(imgs.shift());
});

And a slightly refactored version here.

EDIT:

And here's a version with big images.

var imgs = new Array();
imgs[0] = {small: 'http://farm7.staticflickr.com/6198/6145108610_a5d456dae4_t.jpg',
           big: 'http://farm7.staticflickr.com/6198/6145108610_a5d456dae4_b.jpg'};
imgs[1] = {small: 'http://farm3.staticflickr.com/2564/4064894944_34b0460fc2_t.jpg',
           big: 'http://farm3.staticflickr.com/2564/4064894944_34b0460fc2_b.jpg'};
imgs[2] = {small: 'http://farm9.staticflickr.com/8201/8219867682_7c9aea748f_t.jpg',
           big: 'http://farm9.staticflickr.com/8201/8219867682_7c9aea748f_b.jpg'};

var $img1 = $('#img1');
var $img2 = $('#img2');
var $img3 = $('#img3');

$img1.click(function () {
    $img1.attr('src', imgs[2].small);
    $img2.attr('src', imgs[0].big);
    $img3.attr('src', imgs[1].small);
    imgs.unshift(imgs.pop());
});

$img3.click(function () {
    $img1.attr('src', imgs[1].small);
    $img2.attr('src', imgs[2].big);
    $img3.attr('src', imgs[0].small);
    imgs.push(imgs.shift());
});
