Custom Validate input

Daniel Braun pro premium priority asked 5 years ago

Hello Im trying to do a custom validator for an input but i dont quite understand how you trigger it. I looked at the example and there should be a javascript function right, or how would I trigger data-error?

<div class="md-form">
    <i class="fa fa-envelope prefix"></i>
    <input type="email" id="form9" class="form-control validate">
    <label for="form9" data-error="wrong" data-success="right">Type your email</label>
</div>
thanks
Hi daniel, if you want to validate an input text field (for example the length of the text) you could use the JS event onfocuscout, like below: <input type="text" onfocusout="myFunction()"> I hope this is what you need. Regards.
Hi daniel1, I understand that you need to display your own text validation.
<div class="md-form">
    <i class="fa fa-envelope prefix"></i>
    <input type="email" id="form9" class="form-control validate">
    <label for="form9" data-error="Your Text" data-success="right">Type your email</label>
</div>
If this is not what you need. Please describe the problem better and I will help you. Regards

Hello Thanks for the response What I'm looking for is how can I trigger it with a custom function? Example:

Function validateInput() {
    If (text is wrong) {
        display(data-error);
    }
}
I want to write my own validator like validating the length. I know if it's a error it triggers data-error message but what I would like to know how does it trigger it? Thanks

I think he is wondering how do you run data-error to display the default tooltip error message you see for everything???
Hi, You can easily pass text to data-error and data-success with a message content, all showing is doing in CSS. When you add to input class valid then a success message is shown, when invalid then error. Remove validate class from input to turn off default validation. Regards
