3. Activate the form validation plugin and determine the path to the language JSON.
let validator = $('form.example').jbvalidator({
language: 'dist/lang/en.json'
});
4. Override the default error messages or create your own locals as you see in the en.json
.
{
"maxValue": "You cannot enter a number greater than %s.",
"minValue": "Please enter a number greater than %s.",
"maxLength": "Please use maximum %s character. You are using %s characters.",
"minLength": "Please use minimum %s character, you are using %s characters.",
"minSelectOption": "Please select at least %s options.",
"maxSelectOption": "Please select at most %s options.",
"groupCheckBox": "Please select at least %s options.",
"equal": "This field does not match %s",
"fileMinSize": "File size cannot be less than %s bytes.",
"fileMaxSize": "File size cannot be more than %s bytes.",
"number": "Please write a number."
}
5. The examples shows how to validate form fields on the server side.
$(document).on('submit', '.example', function(){
$.ajax({
method:"get",
url:"test.json",
data: $(this).serialize(),
success: function (data){
if(data.status === 'error') {
validatorServerSide.errorTrigger($('[name=username]'), data.message);
}
}
})
return false;
});
6. You can also create your own validation rules using JavaScript.
validator.validator.custom = function(el, event){
if($(el).is('[name=password]') && $(el).val().length < 5){
return 'Your password is too weak.';
}
}
7. Determine whether to apply a Success to form fields when valid. Default: false.
let validator = $('form.example').jbvalidator({
language: 'dist/lang/en.json',
successClass: true
});
8. Override the default CSS classes.
let validator = $('form.example').jbvalidator({
validFeedBackClass: 'valid-feedbak',
invalidFeedBackClass: 'invalid-feedback',
validClass: 'is-valid',
invalidClass: 'is-invalid'
});
