vue+element表单验证（身份证（校验），手机号码,导游证

基于vue.js 和 element-ui <el-form> 的 validate验证实现

<el-form class="demo-ruleForm" :model="row" :rules="rules" ref="checkFrom"  :model="rulesFrom">
      <div class="form-item-width" style="justify-content: center;">
              <el-form-item label="证件号码" label-width="100px" prop="credentialsCode">
                   <el-input
                      class="input-cardnum"
                      name="card"
                      v-model="rulesFrom.credentialsCode"
                      autocomplete="off"
                    ></el-input>
                  </el-form-item>
                  <el-form-item label="手机号码" label-width="100px" prop="mobile" >
                    <el-input
                      class="input-cardnum"
                      name="card"
                      v-model="rulesFrom.mobile"
                      autocomplete="off"
                    ></el-input>
                  </el-form-item>
                  <el-form-item label="导游证号码">
                    <el-input clearable v-model="rulesFrom.tourGuideCardNum" placeholder="请输入"></el-input>
                  </el-form-item>
                </div>
              </el-form>

注意：

1.规则方法写在data里return之前

2. 身份证有效性校验规则来源与百度

校验公示：∑(ai×Wi)(mod 11)
