完美禁用elinput type为password自动填充密码功能

1.autoComplete='new-password'

2.autoComplete='off'
上述两种情况都无效

html部分代码

<el-form-item
                       :prop="'paramList.' + scope.$index + '.paramValue'"
                        :rules="paramsRules.paramValue"
                      >
                        <template v-if="scope.row.paramCode ==='password'">
                          <el-input
                            type="password"
                            :autoComplete="scope.row.paramCode === 'password'? 'new-password' : 'off'"
                            :value='scope.row.paramValue'
                            @input='pwdInput($event,scope.row)'
                            placeholder='请输入参数值'
                            :readonly="readonly" <!--默认是true--->
                            auto-complete="confirm-password"
                            @focus="changAttr($event,'focus')"
                            @blur="changAttr($event,'blur')"
                            @click.native="clickEvt"
                            ref="password"
                          >
                          </el-input>
                        </template>
                        <template v-else>
                          <el-input

                          </el-input>
                        </template>
                      </el-form-item>
