Troubleshooting regex validation issues in a JSFiddle form

Link to JSFiddle

I encountered an issue with JSFiddle and I am having trouble figuring out the root cause. My aim is to validate an input using a regex pattern for a person's name.

$("document").ready(function() {
  function validateForm() {
    var userName = $("input[name=userName]").val();
    var subject = $("input[name=subject]").val();
    var message = $("input[name=message]").val();

    if (/^[a-zA-Z ]{2,30}$/.test(userName)) {
      alert("Your name is in the correct format");
    } else {
      alert("Your name can't contain numbers or special characters.");
    }
  }
})

Answer №1

Everything looks good from my perspective, but I suggest incorporating return false to stop the form from submitting the formData.

Furthermore, it is advisable to separate the JavaScript logic from the HTML structure.

$("document").ready(function(){
    $('form').on('submit', function() {
        var userName = $("input[name=userName]").val();
        var subject = $("input[name=subject]").val();
        var message = $("input[name=message]").val();
        if (/^[a-zA-Z ]{2,30}$/.test(userName)) {
             alert("Your name is correctly formatted");
        }
        else{
            alert("Your name cannot contain numbers or special characters.");
            return false;
        }
    });
});
