页面的head部分，需设置好页面的样式并引入jQuery文件，代码如下：

<style type="text/css">
*{
	margin: 0;
	padding: 0;
	font-family: 'Microsoft YaHei','Lantinghei SC','Open Sans',Arial,'Hiragino Sans GB','STHeiti','WenQuanYi Micro Hei','SimSun',sans-serif;
}
#upBox{
	text-align: center;
	width:500px;
	padding: 20px;
	border: 1px solid #666;
	margin: auto;
	margin-top: 150px;
	margin-bottom: 200px;
	position: relative;
	border-radius: 10px;
}
#inputBox{
	width: 100%;
	height: 40px;
	border: 1px solid cornflowerblue;
	color: cornflowerblue;
	border-radius: 20px;
	position: relative;
	text-align: center;
	line-height: 40px;
	overflow: hidden;
	font-size: 16px;
}
#inputBox input{
	width: 114%;
	height: 40px;
	opacity: 0;
	cursor: pointer;
	position: absolute;
	top: 0;
	left: -14%;
	
}
#imgBox{
	text-align: left;
}
.imgContainer{
	display: inline-block;
	width: 32%;
	height: 150px;
	margin-left: 1%;
	border: 1px solid #666666;
	position: relative;
	margin-top: 30px;
	box-sizing: border-box;
}
.imgContainer img{
	width: 100%;
	height: 150px;
	cursor: pointer;
}
.imgContainer p{
	position: absolute;
	bottom: -1px;
	left: 0;
	width: 100%;
	height: 30px;
	background: black;
	text-align: center;
	line-height: 30px;
	color: white;
	font-size: 16px;
	font-weight: bold;
	cursor: pointer;
	display: none;
}
.imgContainer:hover p{
	display: block;
}
#btn{
	outline: none;
	width: 100px;
	height: 30px;
	background: cornflowerblue;
	border: 1px solid cornflowerblue;
	color: white;
	cursor: pointer;
	margin-top: 30px;
	border-radius: 5px;
}
</style>
<script type="text/javascript" src="js/jquery.min.js"></script>

页面的body部分，在多个div嵌套结构里放入input file文件选择标签，代码如下：

<div style="width: 100%;height: 100vh;position: relative;">
	<div id="upBox">
	 <div id="inputBox"><input type="file" title="请选择图片" id="file" multiple accept="image/png,image/jpg,image/gif,image/JPEG"/>点击选择图片</div>
     <div id="imgBox">
     </div>
     <button id="btn">上传</button>
	</div>
</div>

页面的底部，需引入上传插件，并启用插件设置好相应参数，代码如下：

<script type="text/javascript" src="js/uploadImg.js" charset="utf-8"></script>
<script type="text/javascript">
imgUpload({
	inputId:'file', //input框id
	imgBox:'imgBox', //图片容器id
	buttonId:'btn', //提交按钮id
	upUrl:'',  //提交地址
	data:'file1' //参数名
})
</script>
