I am doing some validation on text boxes. Once the user enters a valid input, the text box should become green and a tick mark should appear at the rightmost corner. Similarly, if the user has entered an invalid data, text box should become red and a cross should appear instead.
For this, I'm using bootstrap's '`
has-error has-feedback
'` and `'
has-success has-feedback
'`
CSS
classes.
My problem is that the textbox is green and has a tick even when the page is loaded for the first time. I need the validation feedback to appear only after the user has entered an input. And the same applies when the form is used to edit the existing records. How can I achieve this ? (I'm not sure if I could use `
$dirty
` and '
$pristine
` to solve this problem)
Below is my Markup.
<div class="form-group" ng-class="(Form.emailAddress.$valid) ? 'has-success has-feedback': 'has-error has-feedback'">
<label for="emailAddress">Email address</label>
<span ng-show="!Form.emailAddress.$valid">Please enter a valid address</span>
<input type="email" class="form-control" id="emailAddress" name="emailAddress" ng-model="Data.emailAddress" ng-pattern="validationPattern" ng-maxlength="20">
<span ng-show="Form.emailAddress.$valid" class="glyphicon glyphicon-ok form-control-feedback"></span>
<span ng-show="!Form.emailAddress.$valid" class="glyphicon glyphicon-remove form-control-feedback"></span>
</div>
I also tried
<div ng-class="(contactDetailsForm.emailAddress.$valid) && contactDetailsForm.emailAddress.$dirty ? 'has-success has-feedback': 'has-error has-feedback'">
but then the textbox becomes red by default when the page is loaded.
A few more questions regarding this topic.
I would like to check the maxlength of the email as well, and if it exceeds 20, I would want to show a different message. I tried
Form.emailAddress.$maxlength
but couldn't get it working. Does it
maxlength
work on '
email
' types as well ?
How can I show the feedback after the user moves to the next textbox instead of showing it while typing ? May be something similar to jquery's '
focusout()
'.
I've used a validation pattern in the controller because email is not a required field, but when entered it has to be valid. Could I please know if there are better ways than doing this ?
Any help would be much appreciated. Thanks
