下面的代码实例化
jqgrid
当columnModel可用时,还有一个自定义按钮。这很管用。
@Component({
selector: 'somecomp',
templateUrl: './somecomp.component.html'
})
export class SomeComponent implements OnInit{
private _someService;
private _route;
constructor(someService:SomeService,route:ActivatedRoute){
this._someService = someService;
this._route = route;
}
ngOnInit(){
this.someService.getColumnModel.subscribe(columnModel=>{
(<any>jQuery('#grid')).jqGrid({
colModel : columnModel,
caption : 'Data Grid',
url : "http://sampleurl.com/data"
});
//custom button
(<any>jQuery('#grid')).navButtonAdd("#pager",{
buttonicon:"ui-icon-add",
onClickButton : () => {
alert(this._route);//Route(...)
this._route.navigate(["/addPage"]);
}
});
...
单击此按钮时,需要导航到另一页,如图所示。但是,这个警告是未定义的,并给出了错误
Cannot read property 'navigate' of undefined
.
如何确保
this._route
有空吗?
