v0.5.3 is released on 2014.11.05!

regexp validator

Check if the value matches given Javascript regular expression

Options

Option	HTML attribute	Type	Description
`message`	`data-bv-regexp-message`	String	The error message
`regexp`^*	`data-bv-regexp-regexp` or `pattern`	String	The Javascript regular expression

When setting options via HTML attributes, remember to enable the validator by setting data-bv-regexp="true".
You don't need to do that when using HTML 5 pattern="..." attribute.

Using a correct pattern

If the validator still pass when the field value doesn't match the pattern, please ensure you use a correct pattern.

Here are some check lists:

Is the pattern wrapped between ^ and $?

For example, if a field must be 5 digits number, then ^\d{5} (no $ at the end) is wrong pattern. ^\d{5}$ is right one.
Does the pattern work with external services?

You can use the following services to test the regular expression:

Examples

In the following form, user is asked to enter the full name which alphabetical characters and spaces only.

Basic example

<form id="regexpForm" class="form-horizontal">
    <div class="form-group">
        <label class="col-sm-3 control-label">Full name</label>
        <div class="col-sm-4">
            <input type="text" class="form-control" name="fullName" />
        </div>
    </div>
</form>

$(document).ready(function() {
    $('#regexpForm').bootstrapValidator({
        feedbackIcons: {
            valid: 'glyphicon glyphicon-ok',
            invalid: 'glyphicon glyphicon-remove',
            validating: 'glyphicon glyphicon-refresh'
        },
        fields: {
            fullName: {
                validators: {
                    regexp: {
                        regexp: /^[a-z\s]+$/i,
                        message: 'The full name can consist of alphabetical characters and spaces only'
                    }
                }
            }
        }
    });
});

<form id="profileForm" class="form-horizontal"
    data-bv-feedbackicons-valid="glyphicon glyphicon-ok"
    data-bv-feedbackicons-invalid="glyphicon glyphicon-remove"
    data-bv-feedbackicons-validating="glyphicon glyphicon-refresh">

    <div class="form-group">
        <label class="col-lg-3 control-label">Full name</label>
        <div class="col-lg-4">
            <input type="text" class="form-control" name="fullName"
                data-bv-regexp="true"
                data-bv-regexp-regexp="^[a-z\s]+$"
                data-bv-regexp-message="The full name can consist of alphabetical characters and spaces only" />
        </div>
    </div>
</form>

<script>
$(document).ready(function() {
    $('#profileForm').bootstrapValidator();
});
</script>

HTML 5 example

By default, the regexp validator will be used if the field uses HTML 5 pattern attribute. In order to disable the validator, just simply set data-bv-regexp="false".

<form id="meetingForm" class="form-horizontal"
    data-bv-feedbackicons-valid="glyphicon glyphicon-ok"
    data-bv-feedbackicons-invalid="glyphicon glyphicon-remove"
    data-bv-feedbackicons-validating="glyphicon glyphicon-refresh">

    <div class="form-group">
        <label class="col-sm-3 control-label">Meeting time</label>
        <div class="col-sm-4">
            <input type="text" class="form-control" name="time" placeholder="HH:mm"
                pattern="^(09|1[0-7]{1}):[0-5]{1}[0-9]{1}$"
                data-bv-regexp-message="The meeting time must be between 09:00 and 17:59" />
        </div>
    </div>
</form>

$(document).ready(function() {
    $('#meetingForm').bootstrapValidator();
});
