**简介：** 扫码的两种实现：①直接对外部进行扫描；②点开相册对已有图片进行扫一扫  
**完整代码一**

<button type="button" class="mui-btn mui-btn-blue" id="btn">按钮</button>
    <div id="bcid"></div>
    <script type="text/javascript">
    	var btn = document.getElementById("btn");
    	btn.addEventListener("tap",function(){
          
    		var bc = new plus.barcode.Barcode("bcid",[],{
          });
    		bc.start(); //显示动态的扫描条纹
    		
    		// 条码识别成功事件
    		bc.onmarked = function(type,code,file){
          
    			alert(type);  //识别到的条码类型
    			alert(code);  //识别到的条码数据
    			alert(file);  //识别到的图片文件路径
    		}
    		 // 条码识别失败事件
    		bc.onerror = function(){
          
    			
    		}
    	});
    </script>

<button type="button" class="mui-btn mui-btn-blue" id="pick">从相册选取图片</button>
    <script type="text/javascript">
    	var pick = document.getElementById("pick");
    	// 打开系统相册
    	pick.addEventListener("tap",function(){
          
    		plus.gallery.pick(function(filepath){
          
    			plus.barcode.scan(filepath,function(type,code){
            // scan：通过图片扫描条码数据
    				alert(type);
    				alert(code);
    			})
    		})
    	})
    </script>
