<script src="dcat-validator.bundle.js"></script>
<script>
// Call the library function validate
var feedback = validate('DCATstring', validatorRules, callback);
// Console.log all the messages of the errrors and warnings
var callback = function() {
// Errors
for(resource in feedback['errors']) {
for(error in feedback['errors'][resource].error) {
console.log(feedback['errors'][resource].error[error].message);
}
}
// Warnings
for(resource in feedback['warnings']) {
for(warning in feedback['warnings'][resource].error) {
console.log(feedback['warnings'][resource].error[warning].message);
}
}
}
</script>The validationRules
This JSON array must be passed as the second argument to the validate function. You can change the array to your needs but this is the standard JSON array:
var validatorRules = new Array();
validatorRules['mandatory'] =
