Question

我想检查是否有错误，但现在它没有检查是否有任何错误。即使字段为空，表单也会提交。不知道故障在哪里。有人可以帮助表格中的所有字段都是正确的我认为if(error == 0)：

出了问题

  <script>
$(document).ready(function(){

    var errormsg = ['Please enter name.', 'Please enter minimum 3 character.', 'Value not more than 100 characters.', 'Please enter email.', 'Please enter valid email.', 'Email and confirm email does not match.', 'Please enter password', 'Please enter role.', 'Email already exists'];

Answer 1

代码出错。额外的括号，所以否则不起作用。语法错误：

  if(error == 0){
    $(".myForm").submit();
  }
} // Extra braces, so else doesn't work. Syntax error. So remove it.

  else {
    return false;
  }

更新了正确的代码：

if(error == 0){
  $(".myForm").submit();
}

else {
  return false;
}
