> （可直接粘贴过去，需要改宽度和高度，修改\_init方法中的宽和高）

## 2.2 登录页面 ##

### 2.2.1 引入组件 ###

[....<script>]
    
    import { GVerify } from '../../static/js/verifyCode';
    
    [export default { ....]

### 2.2.2 定义验证对象 ###

注意 `verifyCode`

data: function () { 
        return { 
          title: '若晨后台管理系统',
          ruleForm: { 
            username: '',
            password: '',
            verifyCode: ''
          },
          rules: { 
            username: [
              {  required: true, message: '请输入用户名', trigger: 'blur' }
            ],
            password: [{  required: true, message: '请输入密码', trigger: 'blur' }],
            verifyCode: [
              {  required: true, message: '请输入验证码', trigger: 'blur' }
            ]
          },
          verifyCode: null
        }
      },

### 2.2.3 初始化节点 ###

<el-form-item prop="verifyCode" class="verifyCodeItemCss">
              <el-input class="verify_css" placeholder="请输入4位验证码" v-model="ruleForm.verifyCode" @keyup.enter.native="submitForm('ruleForm')"></el-input>
              
              <div id="v_container"></div>
    </el-form-item>

mounted方法中初始化 `'v_container'` 为div的id

mounted () { 
        this.verifyCode = new GVerify('v_container')
    }

### 2.2.4 验证输入的是否正确 ###

通过在data中定义的`verifyCode`对象的`validate()`方法，如果输入正确返回`true` 错误返回 `false`

var that = this
    
          // 获取验证码
          var verifyCode = this.ruleForm.verifyCode
          var verifyFlag = this.verifyCode.validate(verifyCode)
          if (!verifyFlag) { 
            that.$notify.error({ 
              title: '系统提示',
              message: '验证码输入错误'
            })
            return;
          } else { 
            that.$notify({ 
              title: '系统提示',
              message: '验证码输入正确',
              type: 'success'
            })
          }
