在非营利组织的礼品条目网格模板中配置列组件

单元格显示组件

默认情况下，“指定”列组件显示空值。如果一个指定与礼品条目行相关联，列组件会将金额连接到该指定，并将其显示在网格中，例如 100 美元。如果有两个或多个指定，网格将显示汇总值，例如 2 个指定。

单元格显示组件有以下要求：

• JavaScriptjs 文件中的 tagName 值。
• @api 参数充当从网格传递的入站属性。

在此示例中，显示组件会显示条形码列。在输入任何数据之前，将显示为待处理。当系统找到匹配值时，列会更新以显示捐赠者的姓名。

    <p>{columnDisplayValue}</p>

giftEntryGridBarCodeDisplayColumn.js

import { api, LightningElement } from 'lwc';

export default class GiftEntryGridBarCodeDisplayColumn extends LightningElement {
    /**
     * params is the only inbound property passed to this component from Gift Entry Grid
     */
    @api params;

    /**
     * Example Method:
     * This getter function displays various fields in a display component
     * that is specified in the yaml file configuration.
     * @returns {*|string}
     */
    get columnDisplayValue() {
        let response = this.params?.data?.properties?.barCodeValue;
        if (this.params?.data?.LastName) {
            response = this.params?.data?.FirstName + " " + this.params?.data?.LastName;
            if (this.params?.data?.Salutation) {
                response = this.params?.data?.Salutation + " " + response;
            }
        }
        return response || '(pending)';
    }
}
// Tagname is required for the component to function
GiftEntryGridBarCodeDisplayColumn.tagName = 'c-gift-entry-grid-bar-code-display-column';

单元格编辑组件

在默认模板中，“指定”列的编辑组件的 Lightning 输入字段的功能与查找字段相似。在用户输入值时，系统会在自定义条形码对象中查找匹配值。如果找到匹配项，该记录中的值会填充礼品条目网格中的其他列。

单元格编辑组件有以下要求：

• JavaScript 文件中的 tagName 参数。
• JavaScript 文件中设置为真的 isPopup 参数。
• 使用@salesforce/messageChannel/lightning__giftEntryGridComponentAction的礼品输入网格 Lightning 信息服务渠道。
• 以下示例中调用的其他方法和变量。
