 //出库
 output: function () {
   console.log("出库请求---");   	         
   var lock=false;//默认未锁定
   var myconfirm=layer.confirm('是否确认出库?',{btn: ['确定','取消']},function(index){
      console.log('suess');
      console.log(lock);
       //
       if(!lock){
      	 lock=true;//锁定
        //发送
       console.log("ajax---");
        //发送ajax
        $.ajax({
         url: '/dubbo/../outBoundByTask.json',
         isAysn: false,
         type: 'get',
