《远程搜索+单选》组件区别于element-ui或iview组件库的select远程搜索， ①将头部显示的值和下拉选项显示的值独立开来， ②避免远程加载时头部默认值显示异常， ③支持插槽自定义 ④将搜索框值放置于下拉弹框里面

export default {
    inject: {
        FormInstance: {
            default: ''
        }
    },
    computed: {
        itemDisabled () {
            let state = this.disabled;
            if (!state && this.FormInstance) state = this.FormInstance.disabled;
            return state;
        }
    }
};
