Angular2 ng2-smart-table

ng2-smart-table

入门

安装

你要做的就是运行以下命令：

npm install --save ng2-smart-table

此命令将创建在你的`package.json`文件和安装包到 npm_modules 文件夹.

实例

最小安装程序的例子

你首先需要做的就是导入ng2-smart-table directives到你的组件。

import { Ng2SmartTableModule } from 'ng2-smart-table';

然后通过添加模块的指令列表来注册它：

    
// ...

@NgModule({
  imports: [
    // ...
    
    Ng2SmartTableModule,
    
    // ...
  ],
  declarations: [ ... ]
})
// ...

现在，我们需要配置表并将其添加到模板中。组件开始工作时唯一需要的设置是列配置。让我们注册组件的内部设置属性，在其中我们希望拥有表并配置一些列（设置文档）：

settings = {
  columns: {
    id: {
      title: 'ID'
    },
    name: {
      title: 'Full Name'
    },
    username: {
      title: 'User Name'
    },
    email: {
      title: 'Email'
    }
  }
};

最后，让我们把ng2-smart-table component inside模板：

    
// ...

@Component({
  template: `
    <ng2-smart-table [settings]="settings"></ng2-smart-table>
  `
})
// ...

在这一步你将有一个最小配置的表应该看起来像这样：

默认情况下，所有函数都可用，并且不需要以某种方式配置它们，所以您已经能够添加/编辑/删除行，排序或筛选表等。但感觉好像缺少了什么…对，默认情况下表中没有数据。要添加一些，让我们用组件中的对象列表创建数组属性。请注意，对象键与列配置相同。

data = [
  {
    id: 1,
    name: "Leanne Graham",
    username: "Bret",
    email: "Sincere@april.biz"
  },
  {
    id: 2,
    name: "Ervin Howell",
    username: "Antonette",
    email: "Shanna@melissa.tv"
  },
  
  // ... list of items
  
  {
    id: 11,
    name: "Nicholas DuBuque",
    username: "Nicholas.Stanton",
    email: "Rey.Padberg@rosamond.biz"
  }
];

并将数据传递到表格：

    
// ...

@Component({
  template: `
    <ng2-smart-table [settings]="settings" [source]="data"></ng2-smart-table>
  `
})
// ...

现在你有一些数据在表中：

这是一个最小的设置，我们的最终组件应该是这样的，很简单，嗯？

import { Component } from '@angular/core';

@Component({
  selector: 'basic-example-data',
  styles: [],
  template: `
    <ng2-smart-table [settings]="settings" [source]="data"></ng2-smart-table>
  `
})
export class BasicExampleDataComponent {

  settings = {
    columns: {
      id: {
        title: 'ID'
      },
      name: {
        title: 'Full Name'
      },
      username: {
        title: 'User Name'
      },
      email: {
        title: 'Email'
      }
    }
  };
  
  data = [
    {
      id: 1,
      name: "Leanne Graham",
      username: "Bret",
      email: "Sincere@april.biz"
    },
    // ... other rows here
    {
      id: 11,
      name: "Nicholas DuBuque",
      username: "Nicholas.Stanton",
      email: "Rey.Padberg@rosamond.biz"
    }
  ];
}

定制的过滤器的例子

独立的filter的例子

假设你不需要在每个表列中有一个筛选字段，或者要求说搜索字段应该放在表的外面？幸运的是，这是超级容易实现，要做到这一点，我们需要稍微修改我们的基本组件的例子

Data Source

首先你需要知道的是，所有的数据操作和表必须使用数据源表属性。数据源是在你的数据，可以让你轻松地修改表数据或订阅事件修改表行为的抽象。

访问数据源也可以从表或通过它而不是我们的数据阵列。让我们做第二个选择，因为它需要较少的代码和更说明。让我们通过修改import语句导入数据源类：

import { Ng2SmartTableModule, LocalDataSource } from 'ng2-smart-table';

需要注意的是，import包含一个localdatasource类（这个词的地方在这里意味着数据处理在一个本地的浏览器，而不是在服务器端）。

然后我们创建一个DataSource实例，通过我们的数据阵列，把它视为一个参数的构造函数：

source: LocalDataSource; // add a property to the component

constructor() {
  this.source = new LocalDataSource(this.data); // create the source
}

现在让我们将源传递给表而不是数据数组：

  
// ...

@Component({
  template: `
    <ng2-smart-table [settings]="settings" [source]="source"></ng2-smart-table>
  `
})
// ...

在这一点上，如果你看的结果，将没有任何区别相比，第一个例子。基本上，如果你通过数组表格组件首先要做的是把localdatasource对象数组作为我们在这里做的手工。

现在，我们基本上可以改变在数据源表中的数据以任何方式我们需要过滤，排序，分页的一些网页，创建/删除/修改的行。在我们的例子中，我们需要能够过滤表外的数据，首先让我们添加一个搜索提交到模板与监听器：

  
// ...

@Component({ 
  template: `
    <input #search class="search" type="text" placeholder="Search..." (keydown.enter)="onSearch(search.value)">
    <ng2-smart-table [settings]="settings" [source]="source"></ng2-smart-table>
  `
})
// ...

listener code要求数据源的数据过滤

onSearch(query: string = '') {
  this.source.setFilter([
    // fields we want to include in the search
    {
      field: 'id',
      search: query
    },
    {
      field: 'name',
      search: query
    },
    {
      field: 'username',
      search: query
    },
    {
      field: 'email',
      search: query
    }
  ], false); 
  // second parameter specifying whether to perform 'AND' or 'OR' search 
  // (meaning all columns should contain search query or at least one)
  // 'AND' by default, so changing to 'OR' by setting false here
}

最后一件事，让我们隐藏默认表过滤器，以不与我们的独立：

settings = {
  columns: {
    id: {
      title: 'ID',
      filter: false
    },
    name: {
      title: 'Full Name',
      filter: false
    },
    username: {
      title: 'User Name',
      filter: false
    },
    email: {
      title: 'Email',
      filter: false
    }
  }
};

 
现在表有一个独立的搜索字段：

同样的方式，您可以修改表的数据，例如通过从三分之一方窗体中添加行或侦听一些外部事件。这里是一个完整的组件代码：

import { Component } from '@angular/core';

@Component({
  selector: 'basic-example-source',
  styles: [],
  template: `
    <input #search class="search" type="text" placeholder="Search..." (keydown.enter)="onSearch(search.value)">
    <ng2-smart-table [settings]="settings" [source]="source"></ng2-smart-table>
  `
})
export class BasicExampleSourceComponent {

  settings = {
    columns: {
      id: {
        title: 'ID',
        filter: false
      },
      name: {
        title: 'Full Name',
        filter: false
      },
      username: {
        title: 'User Name',
        filter: false
      },
      email: {
        title: 'Email',
        filter: false
      }
    }
  };
  
  data = [
    // ... our data here
  ];
  
  source: LocalDataSource;
  
  constructor() {
    this.source = new LocalDataSource(this.data);
  }

  onSearch(query: string = '') {
    this.source.setFilter([
      // fields we want to include in the search
      {
        field: 'id',
        search: query
      },
      {
        field: 'name',
        search: query
      },
      {
        field: 'username',
        search: query
      },
      {
        field: 'email',
        search: query
      }
    ], false);
    // second parameter specifying whether to perform 'AND' or 'OR' search 
    // (meaning all columns should contain search query or at least one)
    // 'AND' by default, so changing to 'OR' by setting false here
  }
}

`Checkbox, Select and Completer filter types`
