解决 element-ui input=password 在浏览器会自动填充密码的问题

<el-form-item label="用户名" prop="user_name">
        <el-input v-model="info.user_name" :disabled="updateFlag" auto-complete="off" name="person.user.user_name"></el-input>
      </el-form-item>
      <el-form-item label="厂商" prop="factory">
        <el-input v-model="info.factory" auto-complete="off" name="person.user.factory"></el-input>
      </el-form-item>
      <el-form-item label="密码" prop="password">
        <el-input v-model="info.password" :type="((newPwdReadOnly && info.password) || info.password)?'password':'text'" auto-complete="new-password" name="person.user.new_password" @focus="newPwdFocus($event)" :readonly="newPwdReadOnly" @blur="newPwdBlur($event)" ref="newPwdRef"></el-input>
      </el-form-item>
      <el-form-item label="确认密码" prop="confirmPwd">
        <el-input v-model="info.confirmPwd" :type="((rePwdReadOnly && info.confirmPwd) || info.confirmPwd)?'password':'text'" auto-complete="confirm-password" name="person.user.re_password" @focus="newPwdFocus($event, false)" :readonly="rePwdReadOnly" @blur="newPwdBlur($event, false)" ref="reNewPwdRef"></el-input>
      </el-form-item>

给各输入项加了auto-complete属性，只能避免保存的时候弹出是否保存密码弹框的问题。
内容为空的时候点击type="password"的input框或二次（多次）点击，还是会弹出密码框，所以在上面加了type在password和text之间切换（只能解决第一次多次点击的场景）。
具体解决，给type="password"的输入项增加focus,blur事件和readonly属性

newPwdFocus(evt, isNew = true) {
      if (evt) {
        evt.stopPropagation();
        evt.preventDefault();
      }
      setTimeout(() => {
        if (isNew) {
          this.newPwdReadOnly = false;
        } else {
          this.rePwdReadOnly = false;
        }
      }, 100);
    },
    newPwdBlur(evt, isNew = true) {
      if (evt) {
        evt.stopPropagation();
      }
      if (isNew) {
        this.newPwdReadOnly = true;
      } else {
        this.rePwdReadOnly = true;
      }
    },

关键在于setTimeout 0的延时。
以上还不算完全解决，输入内容，再回车删除内容，发现自动填充框又出来了，所以需要watch以下：

watch: {
    "info.password": function () {
      if (this.info.password === "") {
        this.newPwdReadOnly = true;
        this.newPwdFocus(null);
      }
    },
    "info.confirmPwd": function () {
      if (this.info.confirmPwd === "") {
        this.rePwdReadOnly = true;
        this.newPwdFocus(null, false);
      }
    }
  },

以上还不算完全解决，内容为空的时候点击type="password"的input框或二次（多次）点击，还是会弹出密码框。或者输入密码，回退清空再点击还是会弹出自动填充框。解决办法，加mousedown事件（注意不是keydown，也不是click），当点击（或多次点击）密码框的时候会触发mousedown事件，先失焦就阻止了自动填充框的弹出，再聚焦就实现了鼠标还在输入框的功能

addClickEvt() {
      if (this.$refs.newPwdRef) {
        this.$refs.newPwdRef.$refs.input.onmousedown =  (evt) => {
          if (evt) {
            evt.preventDefault();
            evt.stopPropagation();
          }
          if (this.info.password === "" || this.newPwdReadOnly) {
            this.$refs.newPwdRef.$refs.input.blur();
            setTimeout(() => {
              this.$refs.newPwdRef.$refs.input.focus();
            }, 0);
          }
          return false;
        };
      }
      if (this.$refs.reNewPwdRef) {
        this.$refs.reNewPwdRef.$refs.input.onmousedown =  (evt) => {
          if (evt) {
            evt.preventDefault();
            evt.stopPropagation();
          }
          if (this.info.confirmPwd === "" || this.rePwdReadOnly) {
            this.$refs.reNewPwdRef.$refs.input.blur();
            setTimeout(() => {
              this.$refs.reNewPwdRef.$refs.input.focus();
            }, 0);
          }
          return false;
        };
      }
    },
