javascript - 如何使用 ngx-pagination 在 ionic4 应用程序中对数据进行分页？

Question

我按照此页面( https://www.npmjs.com/package/ngx-pagination )的命令将 ngx-pagination 放入我的 ionic 应用程序中。我收到此错误。似乎 ngx-pagination 包尚未安装成功。还有其他解决方案吗？

错误: core.js:15724 错误错误:未捕获( promise 中):错误:模板解析错误: “pagination-controls”不是已知元素: 1. 如果“pagination-controls”是 Angular 组件，则验证它是否是该模块的一部分。 2. 如果“pagination-controls”是 Web 组件，则将“CUSTOM_ELEMENTS_SCHEMA”添加到该组件的“@NgModule.schemas”以抑制此消息。 (“[错误 ->]”):ng:///LoginPageModule/MenuPage.html@116:27 错误:模板解析错误: “pagination-controls”不是已知元素: 1. 如果“pagination-controls”是 Angular 组件，则验证它是否是该模块的一部分。 2. 如果“pagination-controls”是 Web 组件，则将“CUSTOM_ELEMENTS_SCHEMA”添加到该组件的“@NgModule.schemas”以抑制此消息。 (“[错误->]

看起来您正在延迟加载菜单页面。在这种情况下，您必须在 menu.module.ts

中导入 NgxPaginationModule

注意:确保您的组件在导入 NgxPaginationModule 的同一模块中声明
