SCRIPT / JQUERY:我不能将此代码用于ANGULAR2。如何在ANGULAR中使用这段文字2.或者与我分享实例...... :(
$(document).ready(function () {
var data_input=$('input[name="date"]');
var container=$('.bootstrap-iso form').length>0 ? $('.bootstrap-iso form').parent():"body";
data_input.datepicker({
format: 'mm/dd/yyyy',
container: container,
todayHighlight: true,
autoclose: true,
})
})

此代码仅适用于普通模式。它将在angular2.plz中工作,帮助我解决这个问题
$(document).ready(function () {
var data_input=$('input[name="date"]');
var container=$('.bootstrap-iso form').length>0 ? $('.bootstrap-iso form').parent():"body";
data_input.datepicker({
format: 'mm/dd/yyyy',
container: container,
todayHighlight: true,
autoclose: true,
})
})

你不应该在angular / angular2渲染管道之外运行jquery /其他插件。 可能的解决方案是:
创建您自己的组件,类似于:
import { Component, Input, Output, OnInit, AfterViewInit, OnDestroy } from '@angular/core';
import { ViewChild, EventEmitter, ElementRef } from '@angular/core';
@Component({
selector: 'date-time-picker',
template: '<input #input type="text" class="form-control" />'
})
export class DatetimePickerComponent implements AfterViewInit {
@ViewChild('input') input:ElementRef;
ngAfterViewInit() { //only here you are sure that html is available.
$(this.input.nativeElement).datepicker({
format: 'mm/dd/yyyy',
container: container,
todayHighlight: true,
autoclose: true
});
}
}
并在您的应用中随处使用:
<date-time-picker />
也许你也对EventEmitter感兴趣,以捕捉所选值的变化。
如果需要:这是我写的使用http://eonasdan.github.io/bootstrap-datetimepicker/的指令的完整代码和angular2应用程序中的双向数据绑定:
import { Component, Input, Output, OnInit, AfterViewInit, OnDestroy } from '@angular/core';
import { ViewChild, EventEmitter, ElementRef } from '@angular/core';
import { ControlValueAccessor, NgControl } from '@angular/common';
import * as moment from 'moment';
declare var $: JQueryStatic;
//http://eonasdan.github.io/bootstrap-datetimepicker/
@Component({
//moduleId: module.id,
selector: 'date-time-picker',
template: '<input #input type="text" class="form-control" />'
})
export class DatetimePickerComponent implements ControlValueAccessor, OnInit, AfterViewInit, OnDestroy {
@Input('view-mode') viewMode: string;
@Input('view-format') viewFormat: string;
@Input('ngModel') ngModel:Date;
@Output('ngModelChanged') ngModelChanged:EventEmitter<Date>;
private ngModelChangeCallback:(Date)=>void;
private ngModelTouchedCallback:Function;
private jqueryObject: any;
@ViewChild('input') input:ElementRef;
constructor(private ctrl: NgControl) {
this.ctrl.valueAccessor = this;
this.ngModelChanged = new EventEmitter<Date>();
}
ngAfterViewInit() {
let jElement:any = $(this.input.nativeElement);
this.jqueryObject = jElement.datetimepicker({
viewMode: this.viewMode,
format: this.viewFormat,
defaultDate: this.ngModel
});
this.jqueryObject.on("dp.change", (e:any) => {
//this.ngModelChange.emit(e.date.toDate());
this.ngModelChangeCallback(e.date);
this.ngModelChanged.emit(e.date);
});
this.jqueryObject.on("dp.show", (e:any) => {
this.ngModelTouchedCallback(e.date);
});
}
ngOnInit() {
}
ngOnDestroy() {
if(this.jqueryObject) {
$(this.jqueryObject).data("DateTimePicker").destroy();
}
}
writeValue(date:Date) {
if(!this.ngModel && !date) //no changes
return;
if(!moment(this.ngModel).isSame(date)) {
this.ngModel = date;
if(this.jqueryObject) {
$(this.jqueryObject).data("DateTimePicker").date(this.ngModel);
}
}
}
registerOnChange(fn: (Date)=>void) {
this.ngModelChangeCallback = fn;
}
registerOnTouched(fn: Function){
this.ngModelTouchedCallback=fn;
}
}
在其他组件中使用:
<date-time-picker [(ngModel)]="selectedDate" (ngModelChanged)="selectedMonthChanged($event)" view-mode='years' view-format='MM/YYYY'></date-time-picker>

我相信在使用Angular 2时你需要一个新的JS代码入口点。
请参阅Angular2 equivalent of $document.ready()
我不认为您可以轻松地在Angular2中运行您的Bootstrap / Jquery代码而无需移植东西。 您使用的是https://valor-software.com/ng2-bootstrap/吗?
