### 代码演示

#### 表单生成

直接根据设计器中生成的 `json` 即可渲染出表单，获取表单数据。

``` html
<template>
  <div>
    <fm-generate-form 
      :data="jsonData" 
      ref="generateForm"
    >
    </fm-generate-form>
    <el-button type="primary" @click="handleSubmit">Submit</el-button>
  </div>
</template>
```

```js
export default {
  data () {
    return {
      jsonData: {"list":[{"type":"input","icon":"icon-input","options":{"width":"100%","defaultValue":"","required":false,"dataType":"string","pattern":"","placeholder":"","customClass":"","disabled":false,"labelWidth":100,"isLabelWidth":false,"hidden":false,"dataBind":true,"showPassword":false,"remoteFunc":"func_1575897887618","remoteOption":"option_1575897887618"},"name":"单行文本","key":"1575897887618","model":"input_1575897887618","rules":[{"type":"string","message":"单行文本格式不正确"}]}],"config":{"labelWidth":100,"labelPosition":"right","size":"small","customClass":""}},
    }
  },
  methods: {
    handleSubmit () {
      this.$refs.generateForm.getData().then(data => {
        alert(JSON.stringify(data))
      }).catch(e => {
      })
    }
  }
}
```

#### 加载表单数据

```html
<template>
  <div>
    <fm-generate-form 
      :data="jsonData"
      :value="editData" 
      ref="generateForm"
    >
    </fm-generate-form>
  </div>
</template>
```
```js
export default {
  data () {
    return {
      jsonData: {"list":[{"type":"input","icon":"icon-input","options":{"width":"100%","defaultValue":"","required":false,"dataType":"string","pattern":"","placeholder":"","customClass":"","disabled":false,"labelWidth":100,"isLabelWidth":false,"hidden":false,"dataBind":true,"showPassword":false,"remoteFunc":"func_1575897887618","remoteOption":"option_1575897887618"},"name":"名称","key":"1575897887618","model":"name","rules":[{"type":"string","message":"名称格式不正确"}]}],"config":{"labelWidth":100,"labelPosition":"right","size":"small","customClass":""}},
      editData: {
        /* 需要加载的表单数据可以在这里进行设置 */
        name: 'Gavin'
      },
    }
  }
}
```

#### 表单字段值改变事件

表单字段值改变后会触发 `on-change` 事件。

```html
<template>
  <div>
    <fm-generate-form 
      :data="jsonData" 
      @on-change="onChange"
      :value="formData"
      ref="generateForm"
    >
    </fm-generate-form>
  </div>
</template>
```

```js
export default {
  data () {
    return {
      jsonData: {"list":[{"type":"input","icon":"icon-input","options":{"width":"100%","defaultValue":"","required":false,"dataType":"string","pattern":"","placeholder":"","customClass":"","disabled":false,"labelWidth":100,"isLabelWidth":false,"hidden":false,"dataBind":true,"showPassword":false,"remoteFunc":"func_1575897887618","remoteOption":"option_1575897887618"},"name":"名称","key":"1575897887618","model":"name","rules":[{"type":"string","message":"名称格式不正确"}]},{"type":"text","icon":"icon-wenzishezhi-","options":{"defaultValue":"","customClass":"","labelWidth":100,"isLabelWidth":false,"hidden":false,"dataBind":true,"remoteFunc":"func_1575906202073","remoteOption":"option_1575906202073"},"name":"","key":"1575906202073","model":"show","rules":[]}],"config":{"labelWidth":100,"labelPosition":"right","size":"small","customClass":""}},
      formData: {
        show: ''
      }
    }
  },
  methods: {
    onChange (field, value) {
      if (field == 'name') {
        this.formData.show = value
      }
    }
  }
}
```
