I'm having trouble getting form validation to work properly. Please help.

I'm having trouble getting the form to validate properly. I'd like it to iterate and check for user input to have a value that that isn't what their placeholder is or is not an empty string.

<form action="#" method="post" onsubmit = "formValidate()"> <input id="home-worth-name" class ="validateMe" value="Name*" name="Name*" type="text" required="required" onblur="if (this.value == '') { this.value = 'Name*'; }" onfocus="if (this.value == 'Name*') { this.value = ''; }"/> <input id="home-worth-address" class ="validateMe" value="Address*" name="Address*" type="text" required="required" onblur="if (this.value == '') { this.value = 'Address*'; }" onfocus="if (this.value == 'Address*') { this.value = ''; }"/> <input id="home-worth-email" class ="validateMe" value="Email*" name="Email*" type="text" required="required" onblur="if (this.value == '') { this.value = 'Email*'; }" onfocus="if (this.value == 'Email*') { this.value = ''; }"/> <input id="home-worth-phone" value="Phone" name="Phone" type="tel" onblur="if (this.value == '') { this.value = 'Phone'; }" onfocus="if (this.value == 'Phone') { this.value = ''; }"/> <input id="home-worth-submit" name="home-worth-submit" type="submit" value="Send my estimate"/> <div id="home-worth-errorLabel" style="color: #fff; display: none; font-weight: bolder; padding: 1%;">Please fill out all required fields</div> <div id="home-worth-successLabel" style="color: green; visibility: hidden; font-weight: bolder; text-align: center">Request Submitted Sucessfully</div> </form>

<script> function formValidate() {

    var validateInput = $('.validateMe');

    validateInput.each(function () {
        var name = $('#home-worth-name').val();
        var address = $('#home-worth-address').val();
        var email = $('#home-worth-email').val();
        var phone = $('#home-worth-phone').val();
        var errorDiv = $('#home-worth-errorLabel');


            if (validateInput.val() != 'Name*') {
                name = $('#home-worth-name').val();
                $('#home-worth-name').css('border', '0');
                errorDiv.css('display', 'none');
            } else {
                $('#home-worth-name').css('border', '2px solid red');
                errorDiv.css('display', 'none');
                return false;
            }
            if (validateInput.val() != 'Address*') {
                address = $('#home-worth-address').val();
                $('#home-worth-address').css('border', '0');
                errorDiv.css('display', 'none');
                return false;
            } else {
                errorDiv.css('display', 'block');
                $('#home-worth-address').css('border', '2px solid red');
                return false;
            }
    });

    return false;
}
