        contact_email: [
          { validator: validateEmail, trigger: "blur", required: true },
        ],
      },

当提交表单时，检查手机号有没有修改过，如果有修改过并且还带有星号就去校验，但是因为form是循环，只要出现一个带有星号的所有的该字段都会校验并报错，如何只校验我form数组某一项的这个字段

Answer 1

const validatePhone = (index) => {
  return (rule, value, callback) => {
    const starRegex = /\*+/; // 匹配包含星号的字符串
    if (!value) return callback(new Error("手机号不能为空"));
    if (value && !starRegex.test(value)) {
      if (detectPhone(value)) {
        callback();
      } else {
        callback(new Error("请输入正确的联系方式"));
      }
    } else if (
      typeof index === "number" &&
      this.openForm.student_list[index].student_phone !=
        this.originalStudentList[index].student_phone &&
      starRegex.test(value)
    ) {
      callback(new Error("请输入正确的联系方式"));
    } else {
      console.log("2222");
      callback();
    }
  };
};

然后：

<el-form-item
  label="手机号"
  :prop="'student_list[' + index + '].student_phone'"
  :rules="validatePhone(index)"
>
  <el-col :span="8">
    <el-input
      @blur="checkFormEdit(index)"
      v-model.trim="item.student_phone"
      clearable
      placeholder="请输入真实有效的手机号"
    ></el-input>
  </el-col>
</el-form-item>
