我收到确认密码不匹配的错误消息，但我的数据库仍然添加了新列表！为了使脚本停止提交表单，我需要做什么？我对编码的理解很薄弱！

<script src="scripts/jquery.js" type="text/javascript">
jQuery(function(){
  $("#submit").click(function(){
    $(".error").hide();
    var hasError = false;
    var passwordVal = $("#password").val();
    var checkVal = $("#repeatpassword").val();
    if (passwordVal == '') {
      $("#password").after('<span class="error">Please enter a password.</span>');
      hasError = true;
    } else if (checkVal == '') {
      $("#repeatpassword").after('<span class="error">Please re-enter your password.</span>');
      hasError = true;
    } else if (passwordVal != checkVal ) {
      $("#repeatpassword").after('<span class="error">Passwords do not match.</span>');
      hasError = true;
    }
    if(hasError == true) {return false;}
  });
});
</script>

我建议绑定到表单的提交事件，然后完全阻止默认操作，仅在您希望提交时才提交。

$("#formid").submit(function(event){
   event.preventDefault();

   // validate form
   var valid = true;

   if (valid) {
       this.submit();
   }
});

这可以防止您的表单由于错误或逻辑问题而意外提交（除非逻辑问题涉及 的值valid）。

Try binding to the form's submit() event instead of the button's click() event.

So, on the third line, instead of

$("#submit").click(function(){

Use

$("form").submit(function(){
