我的angular2js项目中有很多下拉列表。我正在使用ng2-select2来获取这些下拉列表。在某些下拉列表中,我需要根据字符串用户类型从API中过滤并获取数据到select2搜索框中。插件初始化但不会触发任何AJAX。
到目前为止我的代码:
HTML:
import { Component,OnInit } from '@angular/core';
import {Select2OptionData} from 'ng2-select2';
import {AlertService, LTJService} from '../../_services/index';
import { Observable } from 'rxjs/Observable';
@Component({
selector: 'nationalities',
templateUrl: '../../views/buyer_profile/nationalities.component.html',
})
export class NationalityComponent implements OnInit {
//public nationalities: Observable<Array<Select2OptionData>>;
public options: Select2Options;
public ajaxOptions: Select2AjaxOptions;
constructor(private alertService: AlertService, private ltjService: LTJService) {
}
ngOnInit(): void {
console.log('In ngOnInit');
this.ajaxOptions = {
url: '<API URL>',
dataType: 'json',
delay: 250,
cache: false,
data: (params: any) => {
console.log("AA", params);
return {
query: params.term,
gotoPage: params.page
}
},
processResults: (data: any, params: any) => {
params.page = params.page || 1;
console.log('data: ', data);
return {
results: $.map(data.data, function(obj) {
return {id: obj.id, text: obj.name};
}),
pagination: {
more: (params.page * 10) < data.objectValue.total_count
}
};
},
};
this.options = {
ajax: this.ajaxOptions
}
}
}
组件:
boot
有人能指出我正确的方向吗? 任何帮助都非常感谢。

你使用的数据只输入数据而不是选项
<select2 [data]="options | async"></select2>
试
<select2 [options]="options | async"></select2>
