      deleteAll.onclick=function(){

          if(selectedTotal.innerText!='0'){

              var conf=confirm('确认全部删除?');

              if(conf){

                  for(var i=0,len=trs.length; i<len; i++){

                      console.log(trs[i]);

                      var input=trs[i].getElementsByTagName('input')[0];

                      if(input.checked){

                          trs[i].parentNode.removeChild(trs[i]);

                          len--;  //老师没有改伪数组的长度，这会造成bug，无法运行改变选中数量及选中总计价格

                          i--;

                      }                

                  }

                  //改变选中数量及选中总计价格
                  selectedTotal.innerText='0'; 
                  priceTotal.innerText='0.00';

              }

          }

      }
