this one helps. The problem is that you confused = (assignment operator) operator with == (comparison operator):
code :
if (fName = "" || lName = "" || uName = "" || pWord = "") {
if (fName == "" || lName == "" || uName == "" || pWord == "") {

This might help you Because initially it does not have any characters, try adding a check to character length
Checkout example
code :
$("#submit").on("click",function(){
	var name = $("#name").val();
  if (name.length>0 && !(/^[A-Za-z]+$/).test(name)) {
      alert("Name must be in character only.");
      return false;
  }
  else{
   alert("ok");
  }
})
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input id="name"><input type="submit" id="submit">

it should still fix some issue You could solve it by using 'event.preventDefault'. (But your code should work too...) Here is example code:
code :
<html>
<head>
    </head>
    <body>
	<form name="myForm" onsubmit="validateForm(event)">
	    Name: <input type="text" name="fname" value=" ">
	    Middle Name: <input type="text" name="mname" value=" ">
	    <input type="submit" value="Submit">
	</form>
	<script type="text/javascript">
	    function validateForm(e) {
                var x = document.forms["myForm"]["fname"].value;
                if (x == " ") {
                    e.preventDefault();
                    alert("Name must be filled out");
                    return false;
                }
                var y = document.forms["myForm"]["mname"].value;
                if (y == " ") {
                    e.preventDefault();
                    alert("middle name must be filled out");
                    return false;
                }
            }
        </script>
     </body>
</html>
