Javascript验证不适用于单击功能

Question

我试图在单击功能上使用Java脚本来验证表单，即在表单提交过程中，并且如果条件被删除，我会收到警报消息，但是警报消息应该显示在if条件下，即当表单为空时

$(document).ready(function(){
 $('#submit').click(function(){
     var name = $().val("#name");
     var email = $().val("#email");
     if(name == '' || email == ''){
     alert("test");
     }
  });
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>
<form>
<input id="name" type="text" placeholder="name">
<input id="email" type="email" placeholder="email">
<button id="submit" type="submit">submit</button>
</form>

Answer 1

In jQuery, input values are retrieved with $(element).val(). Your variables should look like this:

var name = $('#name').val();
var email = $('#email').val();

Answer 2

$(document).ready(function(){
 $('#submit').click(function(){
     var name = $("#name").val();
     var email = $("#email").val();
     if(name == '' || email == ''){
     alert("test");
      return false;
     }
  });
});

Answer 3

You are not selecting the input elements you want to get the values from. Replace

var name = $().val("#name");
var email = $().val("#email");

with

var name = $("#name").val();
var email = $("#email").val();
