ElementUI点击按钮单独校验某个表单元素

ElementUI点击按钮单独校验某个表单元素

应用场景：注册时，未输入手机号就点击【获取验证码】，此时应单独校验手机号对应的表单。
提示：validateField(‘需要单独校验的表单项规则’)

以下为HTML代码块：

<el-form :model="ruleForm" :rules="rules" ref="ruleForm" label-width="100px" class="demo-ruleForm" >
<el-form-item label="手机号" prop="account">
      <el-input v-model="ruleForm.account" clearable></el-input>
</el-form-item>
<el-form-item label="密码" prop="password">
      <el-input
                v-model="ruleForm.password"
                type="password"
                clearable=""
              ></el-input>
</el-form-item>
<el-form-item label="确认密码" prop="cfmPwd">
              <el-input
                v-model="ruleForm.cfmPwd"
                type="password"
                clearable=""
              ></el-input>
</el-form-item>
<el-form-item label="验证码" prop="verificationCode">
              <el-input
                v-model="ruleForm.verificationCode"
                type="password"
                clearable=""
              ></el-input>
              <el-button type="primary" @click="postSms"
                >获取验证码</el-button
              >
            </el-form-item>
</el-form>

以下为JS代码块

<script>
export default {
    
    
  data() {
    
    
    var confirmPwd = (rule, value, callback) => {
    
    
      if (value !== this.ruleForm.password) {
    
    
        callback(new Error("两次输入的密码不一致"));
      }
    };
    return {
    
    
      ruleForm: {
    
      // 表单数据
        account: "", // 手机号
        password: "", // 密码
        cfmPwd: "", // 确认密码
        verificationCode: "", // 验证码
      },
      rules: {
    
      // 校验规则
        account: [
          {
    
     required: true, message: "请输入手机号", trigger: "blur" },
          {
    
    
            min: 11,
            max: 11,
            message: "手机号长度为11位",
            trigger: "blur",
          },
        ],
        password: [
          {
    
     required: true, message: "请输入密码", trigger: "blur" },
          {
    
    
            min: 8,
            max: 18,
            message: "长度在 8 到 18 个字符",
            trigger: "blur",
          },
        ],
        cfmPwd: [
          {
    
    
            required: true,
            message: "请再次确认密码",
            trigger: "blur",
          },
          {
    
    
            min: 8,
            max: 18,
            message: "长度在 8 到 18 个字符",
            trigger: "blur",
          },
          {
    
    
            validator: confirmPwd,
            trigger: "blur",
          },
        ],
      },
    };
  },
  methods: {
    
    
    /**
     * 获取验证码
     */
    postSms() {
    
    
      this.$refs["ruleForm"].validateField("account");   // 此行单独校验form表单下的手机号表单项
    },
  }
};
</script>
