        <!--参数说明
        imgUrl = default.jpg 默认图片
        uploadUrl= upfile.php 接收图片接口
        uploadSrc=false 是否上传原图
        showCame=true 是否显示摄像头
        pCut=162|162 裁切框大小
        pSize=162|162|48|48|20|20 预览保存图片大小

        pData=162|162|48|48|20|20 保存图片大小

        例如： imgUrl=./default.jpg&uploadUrl=./upfile.php&uploadSrc=false&showCame=true&pCut=162|162&pSize=162|162|48|48|20|20&pData=162|162|48|48|20|20-->
