element ui 添加动态验证规则

当我们需要给输入框添加动态的规则时，就比如上面这种。当我给移动电话2输入电话时，就需要给它添加上验证规则

	 <el-col :span="6">
            <el-form-item label="移动电话1:" prop="mobilePhoneOne">
              <el-input v-model="formAreas.mobilePhoneOne" size="mini"></el-input>
            </el-form-item>
          </el-col>
          <el-col :span="6">
            <el-form-item label="移动电话2:" prop="mobilePhoneTwo">
              <el-input  v-model="formAreas.mobilePhoneTwo" size="mini"></el-input>
            </el-form-item>
          </el-col>
    

这时候只需要将formAreas.mobilePhoneTwo的验证规则的required的值改为false，它就会自动添加上验证规则

mobilePhoneOne: [
          {
            required: true,
            message: "请输入电话号码",
            trigger: "blur",
          },
          {
            pattern: /^1[3|4|5|6|7|8|9][0-9]\d{8}$/,
            message: "请输入正确的电话号码",
            trigger: ["blur", "change"],
          },
        ],
        mobilePhoneTwo: [
          {
            required: false,
            message: "请输入电话号码",
            trigger: "blur",
          },
          {
            pattern: /^1[3|4|5|6|7|8|9][0-9]\d{8}$/,
            message: "请输入正确的电话号码",
            trigger: ["blur", "change"],
          },
        ],
