Is there a way to prevent entering letters in a date picker field?
I'm currently utilizing bsDatePicker
I attempted using type="number", however I received an error message and was unable to choose a date
"The specified value "02/03/2020" is not a valid number. The value must adhere to the following regular expression: -?(\d+|\d+\.\d+|\.\d+)([eE][-+]?\d+)?"
To declare a variable as a date type, you can simply do the following:
public taskDate = new Date();
This code should be placed in your .ts file.
The following code needs to be included in your .html file:
<input type="text" readOnly class="form-control bsDatepicker"
placeholder="Select Date" [(ngModel)]="taskDate"
[bsConfig]="{ dateInputFormat: 'YYYY-MM-DD' }">
Make sure to include the readOnly attribute in your input element.
To prevent the keypress event, you can use the keypress event preventDefault() method.
Give this a shot:
<div class="col-xs-12 col-12 col-md-4 form-group">
<input (keypress)="$event.preventDefault()"
type="text"
placeholder="Datepicker"
class="form-control"
bsDatepicker>
</div>Alternatively, you can also use the readonly attribute:
<div class="col-xs-12 col-12 col-md-4 form-group">
<input readonly
type="text"
placeholder="Datepicker"
class="form-control"
bsDatepicker>
</div>Check out this example for reference.
Instead of using type="number" in your input field, consider implementing a pattern.
For example:
<input type="text" pattern="(0?[1-9]|[12][0-9]|3[01])/(0?[1-9]|1[012])/\d{4}">Additionally, if you are setting the value of this input from a date picker, it's recommended to make this input field readonly.
If you're looking to solve the issue, simply utilize the date type:
<input type="date"
[minDate]="minDate"
[maxDate]="maxDate"
bsDatepicker [(bsValue)]="yourDateValue">
If you want to filter out non-numeric characters from an input field, you can use the keyup event along with some JavaScript code:
<input onkeyup="this.value=this.value.replace(/[^\d]/,'')" >
