Various issues arising from a single input in Foundation Abide with AngularJS

Trying to set up a form using Foundation has proven challenging, especially when it comes to implementing more advanced error checking. If we take the example of an input field like this:

<input pattern="username" required type="text" placeholder="username" />

Let's assume our custom username regex pattern looks something like this:

^[A-Za-z]{3,6}$

The goal here is to display different errors based on whether the input string exceeds or falls short of that character limit. However, it seems that Foundation Abide struggles with handling this particular scenario, as there are no clear instructions on how to achieve it.

Alternatively, AngularJS is also at our disposal in the same application. I could utilize the ng-min/ng-max directives to handle these validation cases and switch errors accordingly. The concern, though, is that Foundation and Angular may not integrate smoothly, potentially leading to communication issues between frameworks. While the preference is to leverage Foundation for most of the work, presenting a solid case for why Foundation may not be suitable could open up some flexibility.

Is there a way to accomplish this task solely within Foundation? Can we seamlessly combine Angular and Foundation validations, or will we encounter challenges related to Angular's $digest cycles?

Answer №1

If you want to achieve this functionality, you can leverage Foundation. With Abide, you have the ability to define your own custom validation function during the initialization of the foundation. Within this validator, you can utilize DOM manipulation to modify the text inside your error message. Your initialization code would resemble something like the following:

$(document).foundation({
     abide: {
        validators: {
            myCustomValidator: function (el, required, parent) {
                if (el.value.length <= 3) {
                    document.getElementById('nameError').innerText = "Name must have more than 3 characters";
                    return false;
                } else if (el.value.length >= 9) {
                    document.getElementById('nameError').innerText = "Name must have less than 9 characters";
                    return false;
                } //other rules can go here
                return true;
            }
        }
    }
});

After defining the validator, you can then incorporate it into your form label in the following manner:

 <form data-abide>
    <div class="name-field">
        <label>
            Email <small>required</small>
            <input type="text" data-abide-validator="myCustomValidator">
        </label>
        <small id="nameError" class="error">An email address is required.</small>
    </div>
    <button type="submit">Submit</button>
 </form>
