Jquery:如何将图像叠加在一起?

在下面的代码中,我有一个构建衬衫的页面。当用户单击一个选项(“男/女”)时,“#shirt”部分显示通过将 PNG 图像叠加在一起构建的衬衫。例如,选择“蓝色”作为基色将显示蓝色衬衫的图像。然后,选择“罗纹” body 拼接将在蓝色衬衫顶部放置一个图像,添加罗纹细节。现在,我的问题是每个新图像都会替换以前的图像。其他一切正常(选项出现以响应先前选择的选项)。

<div id="gender" class="diy-box">

<input type="radio" name="gender" data-id="" value="male" /><label>Male</label><br>

$(document).ready(function() {
$("div.desc").hide();

var data = {
"105" : { img: "http://oceandrive.localhost/images/diy-images/105.png", label: "color 1", price: "100" },

};


$('input[name]').click(function() {


var value = $(this).val(); // pics the value of the radio button

if(value=='male' || value=='female') {
$("div.gender").hide('slow');
$("div.gender input:radio").removeAttr('checked');
}

if(value=='body_stitching_plain' || value=='body_stitching_rib') {
$("div.body_stitching").hide('slow');
$("div.body_stitching input:radio").removeAttr('checked');
}

$("#" + value).show('slow'); // addresses the div with the radio button value picked



if(this.checked) {

//var value = $(this).val();
var value = $(this).data('id');

if (data[value] != undefined)
{

var html = '';
html = html + '<img style="z-index:2;" src="'+data[value].img+'"/>';
$('#shirt').html(html);

var html = '';
html = html + '- '+data[value].label+' - '+data[value].price+' NT<br>';
$('#pricefield').html(html);

}

}

});

});

最佳答案

首先,您需要确定图像的显示顺序。例如,根据您的代码,我会说您有两个级别(如果需要,您可以添加更多级别):

  1. 基地
  2. body 拼接

其次,将每个级别分配给一个 z-index 并创建 <div>每个元素。这些<div>的样式应使其定位是绝对的,如下所示:

<div id="baseImage" style="z-index:1; position: absolute;"></div>
<div id="stitchImage" style="z-index:2; position: absolute;"></div>
...

我可能还会指定每个 <div> 的宽度/高度以匹配您的图像。

最后,使用 jQuery 定位每个 <div>在基本图像之上。

$("#stitchImage").offset($("#baseImage").offset());

然后,当您需要替换图像时,只需使用您拥有的代码即可:

$("#stitchImage").html("<img src='" + src + "' />");

请注意,您必须使用空白占位图像,以便用户在尚未选择较高层时可以看到较低层。
