以下是一个Angular 7中实现数据表和上传按钮的示例代码:
首先,确保你已经安装了Angular CLI并创建了一个新的Angular项目。
在你的组件的HTML文件中,使用Angular Material的数据表组件和文件上传组件,添加以下代码:
Name
{{element.name}}
Age
{{element.age}}
Email
{{element.email}}
Actions
import { Component, OnInit } from '@angular/core';
import { MatTableDataSource } from '@angular/material/table';
import { SelectionModel } from '@angular/cdk/collections';
@Component({
selector: 'app-your-component',
templateUrl: './your-component.component.html',
styleUrls: ['./your-component.component.css']
})
export class YourComponentComponent implements OnInit {
displayedColumns: string[] = ['select', 'name', 'age', 'email', 'actions'];
dataSource = new MatTableDataSource(ELEMENT_DATA);
selection = new SelectionModel(true, []);
ngOnInit() {
}
edit(element) {
// 编辑逻辑
}
delete(element) {
// 删除逻辑
}
masterToggle() {
this.isAllSelected() ?
this.selection.clear() :
this.dataSource.data.forEach(row => this.selection.select(row));
}
isAllSelected() {
const numSelected = this.selection.selected.length;
const numRows = this.dataSource.data.length;
return numSelected === numRows;
}
handleFileInput(files: FileList) {
// 处理文件上传逻辑
}
upload() {
// 上传逻辑
}
}
const ELEMENT_DATA: any[] = [
{ name: 'John Doe', age: 30, email: 'johndoe@example.com' },
{ name: 'Jane Smith', age: 25, email: 'janesmith@example.com' },
{ name: 'Mike Johnson', age: 35, email: 'mikejohnson@example.com' }
];
这样,你就可以在Angular 7项目中实现一个带有数据表和上传按钮的组件了。
