[英]Add delete event inside delete button to each row of Datatables on Angular and add background-color into button
我可以在每行数据表中放置一个按钮,但该按钮没有任何 function,而且我不知道如何向该按钮添加删除事件。 有人能帮我吗? 希望你也给我演示;) *ps:另外,如何在打印、导出按钮上放置背景颜色。 className: red(on TS) and.red{ background-color: red;}(on CSS) didn't work out:/ *another ps: 我正在使用 datatables.net
TS 文件
products: any = (data as any).default;
ngOnInit(): void {
this.dtOptions = {
ajax: {
url: '',
type: 'GET',
dataType: 'json',
},
columns: [
{
title: 'ID',
data: 'id',
},
{
title: 'Name',
data: 'name',
},
{
title: 'Gender',
data: 'gender',
},
{
title: 'Option',
data: null,
defaultContent:
'<button class="btn-delete type="button">Delete</button>',
targets: -1,
},
],
dom: 'Bfrtip',
buttons: [
{ extend: 'excel', text: 'Export' },
{
text: '<i class="fa fa-files-o"></i>',
action: function (e, dt, node, config) {
dt.ajax.reload();
},
},
{
extend: 'print',
text: 'Print',
},
],
};
}
html
<table
datatable
[dtOptions]="dtOptions"
class="mc row-border hover">
</table>
您可以查看此 演示
您需要在删除过程后重新渲染。 您可以添加如下按钮并为其提供 function。
<table datatable [dtOptions]="dtOptions" [dtTrigger]="dtTrigger" class="row-border hover">
<thead>
<tr>
<th>ID</th>
<th>First name</th>
<th>Last name</th>
<th></th>
</tr>
</thead>
<tbody>
<tr *ngFor="let person of persons">
<td>{{ person.id }}</td>
<td>{{ person.firstName }}</td>
<td>{{ person.lastName }}</td>
<td><button class="btn-delete" (click)="deleterow(person)">Remove</button> </td>
</tr>
<tr *ngIf="persons?.length == 0">
<td colspan="4" class="no-data-available">No data!</td>
</tr>
</tbody>
</table>
在组件中,您需要重新渲染 function
deleterow(person){
console.log(person);
//here do delete event
const that = this;
this.rerender()
}
rerender(): void {
this.dtElement.dtInstance.then((dtInstance: DataTables.Api) => {
dtInstance.destroy();
this.dtTrigger.next();
});
}
并更改您的 afterinit
ngAfterViewInit(): void {
this.dtTrigger.next();
}
