Correct way to retrieve value from mdb-datepicker

Topic: Correct way to retrieve value from mdb-datepicker

Dave Moniz priority asked 3 years ago

The [(ngModel)] is updated AFTER the (dateChanged) event. Also the object itself has no value output.

What is the expected way to acquire the new date value, especially within the (dateChanged) event?

You can retrieve information about new value from the component <code>dateChanged</code> event or from component input using Angular form controls (ngModel/formControl). Please note that <code>opened</code>, <code>closed</code> and <code>dateChanged</code> outputs are attached to the <code>mdb-datepicker</code> component and should be used on this element. Here is an example:

HTML:

<pre class="prettyprint"><code><mdb-form-control>
 <input
 mdbInput
 [mdbDatepicker]="datepicker"
 type="text"
 class="form-control"
 id="exampleDatepicker1"
 [ngModel]="value"
 (ngModelChange)="onModelChange($event)"
 />
 <label mdbLabel for="exampleDatepicker1" class="form-label">Select a date</label>
 <mdb-datepicker-toggle [mdbDatepicker]="datepicker"></mdb-datepicker-toggle>
 <mdb-datepicker #datepicker (dateChanged)="onDateChange($event)" (opened)="onOpen()"></mdb-datepicker>
</mdb-form-control>
</code></pre>

TS:

<pre class="prettyprint"><code> value = new Date();

onModelChange(event: any): void {
    console.log('model change date', event);
  }

onDateChange(event: any) {
    console.log('event', event);
  }

onOpen() {
 console.log('open');
 }
</code></pre>

Try this:

In your HTML file:

<mdb-form-control>
  <input
    mdbInput
    [mdbDatepicker]="basicDatepicker"
    type="text"
    class="form-control"
    id="exampleDatepicker1"
  />
  <label mdbLabel for="exampleDatepicker1" class="form-label">Select a date</label>
  <mdb-datepicker-toggle [mdbDatepicker]="basicDatepicker"></mdb-datepicker-toggle>
  <mdb-datepicker #basicDatepicker (dateChanged)="onDateChanged(value)"></mdb-datepicker>
</mdb-form-control>

In your TS file:

  onDateChanged(value) {
    console.log(value)
  }

Turns out: the problem is much larger.

None of the events on datepicker component are firing. I thought I must be doing it wrong but (valueChange) event on the select that I'm using fires correctly

Grzegorz Bujański staff commented 3 years ago

Please add the TS and HTML code you are using. I'll check it.

Dave Moniz priority commented 3 years ago

It's basically copy/paste of what you have but, if this is want

<div class="col-lg-3 col-xl-3">
    <mdb-form-control>
        <input mdbInput id="eventDatePicker" name="eventDatePicker" [mdbDatepicker]="eventDatePicker" type="text" class="form-control" [(ngModel)]="eventDate" (click)="eventDatePicker.open()" (opened)="onEventDateValueChanged(value)">
        <label mdbLabel for="eventDatePicker" class="form-label">Event Date</label>
        <mdb-datepicker-toggle [mdbDatepicker]="eventDatePicker"></mdb-datepicker-toggle>
        <mdb-datepicker #eventDatePicker [format]="'ddd, mmm d, yyyy'" [startDate]="eventDate"></mdb-datepicker>
    </mdb-form-control>
</div>

onEventDateValueChanged(value: any): void {
            console.log(value);
}

Please insert min. 15 characters.
