Enter 按钮在登录页面上不起作用

Question

我刚刚做了一个登录系统，但我只能通过按屏幕上的按钮登录，不能使用键盘上的回车键。我怎样才能启用它？我阅读了有关 AcceptButton 的内容，但我该如何应用它？

我的代码：

login.php

<?php

    require('inc/functions.php');

    session_start();

    if(checkLogedIn()){
        header("location:index.php");
        die();
    }

    include 'inc/header.php'

?>

<body>
    <div id="wrap">
                <div class="text-center">
                    <img src="img/logo.png" height="125" width="125">
                </div>
        <div class="row">
            <div class="col-xs-10 col-xs-offset-1 col-sm-8 col-sm-offset-2 col-md-4 col-md-offset-4">
                <div class="login-panel panel panel-default">
                    <div class="panel-heading">Inloggen</div>
                    <div class="result"></div>
                    <div class="panel-body">
                        <form role="form" id="loginForm">
                            <fieldset>

                                    <input class="form-control" placeholder="Gebruikersnaam" name="username" type="text" autofocus="">
                                </div>
                                <div class="form-group">
                                    <input class="form-control" placeholder="Wachtwoord" name="password" type="password">
                                </div>

                                <div class="row">

有人能帮忙吗？

Answer 1

您可以将点击修改为：

$('#loginForm').keypress(function (e) {

    if(e.keyCode=='13') //Keycode for "Return"

    $('#login').click();
}});

Answer 2

您可以触发点击进入：

$(document).keydown(function(e){
    var c = e.which;
    e.stopPropagation();
    if(c==13){
        e.preventDefault();
        $(".post").trigger("click");
    }
});

Answer 3

要使输入按钮起作用，您可以使用

<input type="submit">

而不是

<a href="#" class="btn btn-success post">Inloggen</a>

Enter 按钮在登录页面上不起作用
