 $("#login").click(function(){
      console.log("submit");
      console.log($("#username").val());
      $.ajax({
        url:'/apserver/company/login',
        type: 'POST',
        dataType: 'json',
        data:{
          name:$("#username").val(),
          password:$("#password").val()
        },
        success: function(data){
          if (data.status == 0){
            location.href = "home.php";
          }
        }
      });
      console.log("submit")
    })<div class="login">
