Data Entry Page

Data Entry Page is a page type specifically designed for creating form data entry interfaces, implementing visual form design and data submission functionality based on a grid layout architecture. It is responsible for form component layout management, data model binding, and user interaction handling, supporting visual configuration of form field arrangement, validation rules, and submission processes.

The Data Entry Page element hierarchy is Meta (pages.Meta) → Type (pages.FormPageType) → Instance. Developers can quickly create data entry page instance elements through JitAI's visual development tools.

Of course, developers can also create their own Type elements or modify the official pages.FormPageType element provided by JitAI in their own App to implement their own encapsulation.

Advanced Features

Page Inheritance

Data Entry Page supports inheritance mechanism, allowing creation of new pages based on existing pages.

Configuration Example

Inheritance Configuration
{
  "type": "pages.FormPageType",
  "title": "Advanced Customer Entry Page",
  "extend": "pages.BasicCustomerForm",
  "dataModel": "models.CustomerModel"
}

Usage Example

Inheritance Implementation
class AdvancedPageCls extends Jit.GridPage {
    constructor(info: any = {}) {
        super(info);
        // Inherited pages automatically merge parent page configuration
    }
    
    bindEvent() {
        super.bindEvent?.(); // Call parent page event binding
        
        // Add new event bindings
        this.Form1.subscribeEvent("beforeSubmit", async (e) => {
            // Advanced validation logic
            return this.validateAdvancedRules(e.data);
        });
    }
}

URL Parameter Binding

Through matchUarParamsVariableNameList configuration, page variables can automatically get values from URL parameters.

Configuration Example

URL Parameter Binding Configuration
{
  "scheme": {
    "matchUarParamsVariableNameList": ["userId", "deptId"],
    "variableList": [
      {
        "name": "userId",
        "title": "User ID",
        "dataType": "Stext"
      },
      {
        "name": "deptId", 
        "title": "Department ID",
        "dataType": "Stext"
      }
    ]
  }
}

Usage Example

URL Parameter Usage
// Page URL: /pages/CustomerForm?userId=123&deptId=dept001
class PageCls extends Jit.GridPage {
    bindEvent() {
        // When page initializes, userId and deptId automatically get values from URL
        console.log('User ID:', this.userId.value); // Output: 123
        console.log('Department ID:', this.deptId.value); // Output: dept001
        
        // Listen for URL changes
        this.subscribeEvent('URL_CHANGED', () => {
            this.refreshPageVariable(); // Re-get parameters from URL
        });
    }
}

动态组件加载

支持运行时动态添加和配置组件。

使用示例

动态组件管理
class PageCls extends Jit.GridPage {
    async addDynamicComponent() {
        // 创建新组件
        const newComp = await this.newComponent('components.Button', {
            name: 'dynamicBtn',
            title: '动态按钮',
            config: {
                btnType: 'default'
            }
        });
        
        // 绑定到页面
        newComp.bindApp(this.app);
        newComp.bindPage(this);
        
        // 添加到组件字典
        this.compInsDict['dynamicBtn'] = newComp;
        this[newComp.name] = newComp;
        
        // 更新布局
        this.scheme.layout.push({
            i: 'dynamicBtn',
            x: 0,
            y: 10,
            w: 12,
            h: 4
        });
        
        this.refresh();
    }
}

AI集成

数据录入页面支持AI助手功能，可以为用户提供智能填写建议。

配置示例

AI配置
{
  "scheme": {
    "aiConfig": {
      "useAi": 1,
      "aiAssistant": "models.CustomerAIAssistant"
    }
  }
}

使用示例

AI助手集成
class PageCls extends Jit.GridPage {
    async handleAIAssist() {
        if (this.aiConfig?.useAi) {
            await this.sendAiMessage('请帮我分析这个客户的信息', 0);
        }
    }
    
    bindEvent() {
        // 监听AI消息发送事件
        this.subscribeEvent('SEND_AI_MESSAGE', async (e) => {
            console.log('AI消息:', e.message);
        });
        
        // 绑定AI建议按钮
        this.subscribeEvent('AI_SUGGEST', async () => {
            const formData = this.Form1.getFormData();
            await this.sendAiMessage(`请为以下表单数据提供建议：${JSON.stringify(formData)}`, 0);
        });
    }
}

样式定制

通过page.style.ts文件可以自定义页面样式。

使用示例

高级样式定制
import type { GlobalToken } from 'antd';
import { css } from '@emotion/react';

export const pageStyle = (token: GlobalToken) => css`
  .data-entry-container {
    min-height: 100vh;
    background: linear-gradient(135deg, ${token.colorBgBase} 0%, ${token.colorBgLayout} 100%);
    
    .form-section {
      background: ${token.colorBgContainer};
      border-radius: ${token.borderRadiusLG}px;
      box-shadow: ${token.boxShadowSecondary};
      padding: ${token.paddingLG}px;
      margin-bottom: ${token.marginLG}px;
      
      &.highlight {
        border: 2px solid ${token.colorPrimary};
      }
    }
    
    .required-indicator {
      color: ${token.colorError};
      font-weight: bold;
    }
  }
`;

export const pageGlobalStyle = (token: GlobalToken) => css`
  .ant-form-item-required::before {
    color: ${token.colorError} !important;
  }
  
  .custom-form-button {
    background: ${token.colorPrimary};
    border-color: ${token.colorPrimary};
    
    &:hover {
      background: ${token.colorPrimaryHover};
      border-color: ${token.colorPrimaryHover};
    }
  }
`;
