예 형태 : 당신이 백엔드 프런트 엔드에서 자바 스크립트 ajax 전화를 사용하려면

<form role="form" action="http://127.0.0.1:8080/user/login" method="post" name="loginform"> 
         <fieldset> 
          <legend>Login</legend> 
          <div class="form-group"> 
           <label for="email">Email</label> 
           <input type="text" name="email" placeholder="Your Email" required class="form-control" /> 
          </div> 
          <div class="form-group"> 
           <label for="name">Password</label> 
           <input type="password" name="password" placeholder="Your Password" required class="form-control" /> 
          </div> 
          <div class="form-group"> 
           <input type="submit" name="login" value="Login" class="btn btn-primary" /> 
          </div> 
         </fieldset> 
        </form><form role="form" action="http://127.0.0.1:8080/user/login" method="post" name="loginform"> 
         <fieldset> 
          <legend>Login</legend> 
          <div class="form-group"> 
           <label for="email">Email</label> 
           <input type="text" name="email" placeholder="Your Email" required class="form-control" /> 
          </div> 
          <div class="form-group"> 
           <label for="name">Password</label> 
           <input type="password" name="password" placeholder="Your Password" required class="form-control" /> 
          </div> 
          <div class="form-group"> 
           <input type="submit" name="login" value="Login" class="btn btn-primary" /> 
          </div> 
         </fieldset> 
        </form> 

:

$.ajax({ 
     method: 'post', 
     url: '/login', 
     success: function(res) { 
      return 'success'; 
     } 
    })
