Vue.config.productionTip = false;
new Vue({
  router,
  render: h => h(App)
}).$mount('#app');
```

#### 3.使用:

```
<template>
  <div>
    <iss-library-form-renderer 
      :source="schema"
      :value="editData" 
      ref="formRenderer">
    </iss-library-form-renderer>
    <el-button type="primary" @click="handleSubmit">Submit</el-button>
  </div>
</template>

<script>
export default {
  data () {
    return {
      schema: {"list":[],"config":{"labelWidth":100,"labelPosition":"right","size":"small","customClass":"","ui":"element","layout":"horizontal","labelCol":3,"width":"100%","hideLabel":false,"hideErrorMessage":false,"theme":"default","themeTitle":"","themeSubTitle":"","themeTitleAlign":"left","submitHiddenArea":false,"eventScript":[{"key":"mounted","name":"mounted","func":""},{"key":"beforeSubmit","name":"beforeSubmit","func":"// 在表单提交前调用，且返回值会影响提交结果\n// 返回值为true时会继续执行 \n// 返回值为false时会阻止提交 \n// 返回值为Error时会阻止提交 且会修改错误提示信息 return new Error('提示信息'); \nreturn true;"},{"key":"submitted","name":"submitted","func":""}]},"version":1},
      editData: {}
    }
  },
  methods: {
    handleSubmit () {
      this.$refs.formRenderer.getData().then(data => {
        // Data verification succeeded
        alert(JSON.stringify(data))
