      <view class='{{item.classname}}' > 这个是data中的原始值

      {

              word1: "Pedestrian\r\n Street",

              classname: 'text-bg',

              pipei: "8",

              textfonname: 'text-fon',

              flag: true

            }, 这个是点击事件里面不同条件下的改值

      wordMsg[g1].classname = 'text-bg1';

      wordMsg[value_1].classname = 'text-bg2';

          

      wordMsg[value_1].classname = 'text-bg';

      wordMsg[value_1].classname = 'text-bg3';

      wordMsg[value_1].classname = 'text-bg';


      这样写有什么问题吗?
