How to verify dates in Bootstrap?

Bootstrap provides a simple JavaScript plugin for verifying dates in a form.

1. Introduce the necessary scripts and styles

 <code class="html"><link href="https://cdnjs.cloudflare.com/ajax/libs/bootstrap-datepicker/1.9.0/css/bootstrap-datepicker.min.css" rel="stylesheet"> <script src="https://cdnjs.cloudflare.com/ajax/libs/bootstrap-datepicker/1.9.0/js/bootstrap-datepicker.min.js"></script></code>

2. Initialize the date selector

Initialize the datepicker component using datepicker() method as follows:

 <code class="javascript">$('#datepicker').datepicker();</code>

3. Set verification rules

To verify that the date is legal, set data-bv-date property:

 <code class="html"><input id="datepicker" data-bv-date="true"></code>

Verification rule options:

• format : Specify the date format (for example: "YYYY-MM-DD")
• message : Custom error message
• dateLimit : Set date limit (for example: {"max": "10d", "min": "-5d"})
• useCurrent : Specifies whether to use the current date as the initial value

4. Integrate Bootstrap verification framework

To enable Bootstrap verification, include the following script:

 <code class="javascript"><script src="https://cdnjs.cloudflare.com/ajax/libs/bootstrap-validator/0.5.3/js/bootstrapValidator.min.js"></script></code>

Then, initialize the verification form:

 <code class="javascript">$('#form').bootstrapValidator();</code>

5. Application Verification

The Bootstrap verification framework automatically validates date input when the form is submitted. If the date is invalid, an error message will be displayed.
