a simple jquery form validation script


a simple jquery form validation script  using -'jquery,validation'

I made a simple validation form using JQuery. It's working alright. The thing is I'm not satisfied with my code. Is there another way around to write my code with the same output result?  Thank you very much :)

$(document).ready(function(){

$('.submit').click(function(){
    validateForm();   
});

function validateForm(){


    var nameReg = /^[A-Za-z]+$/;
    var numberReg =  /^[0-9]+$/;
    var emailReg = /^([\w-\.]+@([\w-]+\.)+[\w-]{2,4})?$/;

    var names = $('#nameInput').val();
    var company = $('#companyInput').val();
    var email = $('#emailInput').val();
    var telephone = $('#telInput').val();
    var message = $('#messageInput').val();

    var inputVal = new Array(names, company, email, telephone, message);

    var inputMessage = new Array("name", "company", "email address", "telephone number", "message");

     $('.error').hide();

        if(inputVal[0] == ""){
            $('#nameLabel').after('<span class="error"> Please enter your ' + inputMessage[0] + '</span>');
        }
        else if(!nameReg.test(names)){
            $('#nameLabel').after('<span class="error"> Letters only</span>');
        }

        if(inputVal[1] == ""){
            $('#companyLabel').after('<span class="error"> Please enter your ' + inputMessage[1] + '</span>');
        }

        if(inputVal[2] == ""){
            $('#emailLabel').after('<span class="error"> Please enter your ' + inputMessage[2] + '</span>');
        }
        else if(!emailReg.test(email)){
            $('#emailLabel').after('<span class="error"> Please enter a valid email address</span>');
        }

        if(inputVal[3] == ""){
            $('#telephoneLabel').after('<span class="error"> Please enter your ' + inputMessage[3] + '</span>');
        }
        else if(!numberReg.test(telephone)){
            $('#telephoneLabel').after('<span class="error"> Numbers only</span>');
        }

        if(inputVal[4] == ""){
            $('#messageLabel').after('<span class="error"> Please enter your ' + inputMessage[4] + '</span>');
        }       
}   

});

You can simply use the jQuery Validate plugin as follows.

jQuery:

$(document).ready(function () {

    $('#myform').validate({ // initialize the plugin
        rules: {
            field1: {
                required: true,
                email: true
            },
            field2: {
                required: true,
                minlength: 5
            }
        }
    });

});

you can use jquery validator for that but you need to add jquery.validate.js and jquery.form.js file for that. after including validator file define your validation something like this.


You can see required : true same there is many more property like for email you can define email : true for number number : true
