Problems with submit button reloading page when there is an if...else statement.

Problems with submit button reloading page when there is an if...else statement.

Hey guys, I have a form that I perform some AJAX business on when it is submitted. However, I wanted to have an if...else statement but when I add it it allows the page to refresh upon submit. For example...

  2. $(document).ready(function() {

  4. // register form onsubmit function
  5. $('#register_form').submit(function() {
  7. // declare variables
  8.                 var input_email; input_email = $("#register_form_input_email").val();

  10. // verify email
  11.   $.post("emailverifier.php", { email: input_email },
  12. function(data) {
  13. if (data.valid == 1) {
  14. // display ok
  15. $("#register_form_span_email").html("Ok!");
  16. } else {
  17. // display error
  18. $("#register_form_span_email").html("Error!");
  19. }
  20. }, "json"
  21. );

  23. return false;// stop form from refreshing the page
  25. });
  27. }); // end document ready
Works properly, but...

  2. $(document).ready(function() {

  4. // register form onsubmit function
  5. $('#register_form').submit(function() {
  7. // declare variables
  8.                 var input_email; input_email = $("#register_form_input_email").val();

  10. // verify email
  11.   $.post("emailverifier.php", { email: input_email },
  12. function(data) {
  13. if (data.valid == 1) {
  14. // display ok
  15. $("#register_form_span_email").html("Ok!");
  16. } else {
  17. // display error
  18. $("#register_form_span_email").html("Error!");
  19. }
  20. }, "json"
  21. );

  23. if (1=1) {
  24. alert("One indeed equals one!");
  25. } else {
  26. alert("What the...?!?");
  27. }

  29. return false;// stop form from refreshing the page
  31. });
  33. }); // end document ready
Allows the page to refresh.

I'm reasonably new to jQuery and JavaScript so I'm hoping that there is a simple explanation for this. Can anyone tell me why this is?
