percentage属性值定死的状态

                  <el-progress
                    :percentage="80"
                    :format="format"
                    :color="customColors"
                  ></el-progress>

percentage动态变化（加入了运算）

                  <el-progress
                    :percentage="parseInt((item.soldNum / item.num)*100)> 100 ? 100 :parseInt((item.soldNum / item.num)*100)"
                    :format="format"
                    :color="customColors"
                  ></el-progress>
