使用不起作用的按钮显示和隐藏 - Show and Hide using buttons not working

好吧，我一直在尝试修复这个代码，并搜索了大约6个多小时，这让我很痛苦

我试图做的是隐藏登录表和与之相关的背景图像（即#lg#ck），并在登录表所在的位置顶部放置一个按钮，这样当点击它时，它将显示登录表

<?php
require_once( 'inc/header.inc.php' );
require_once( BX_DIRECTORY_PATH_INC . 'design.inc.php' );
require_once( BX_DIRECTORY_PATH_INC . 'db.inc.php' );
require_once( BX_DIRECTORY_PATH_INC . 'profiles.inc.php' );

check_logged();
if(!isMember()) {
echo '<body style="margin:0;">
<div style="margin:0 auto" align=center>
    <form onsubmit="validateLoginForm(this); return false;" method="post" action="member.php" id="login_box_form">
        <table id="ck">
            <tbody>
                <tr>
                    <td width="180">Name</td>
                    <td width="150">Code</td>
                    <td width="50">&nbsp;</td>
                </tr>
                <tr>
                    <td width="180"><input style="width:180px;" name="ID" type="text"></td>
                    <td width="180"><input style="width:180px;"name="Password" type="password"></td>
                    <td><input name="LogIn" type="submit" tabindex="3" value="Login"></td>
                </tr>
                <tr>
                    <td width="180"><input type="checkbox" name="rememberMe"> Keep me logged in</td>
                    <td width="180"><a href="forgot.php">Forgot password?</a></td>
                    <td width="50">&nbsp;</td>
                </tr>
            </tbody>
        </table>
    </form>
</div>
<div style="width:100%;height:20px;clear:both;"></div>
<div style="width:100%;height:600px;padding-left:40px;padding-right:40px;padding-top:20px;">';
}
else {

}

这是有人建议的代码，但我甚至不知道该放在哪里。

<div id="ONE"><input type="button" value="Login" onClick="hideID('ONE');showID('TWO');" /></div>
<div id="TWO" style="display:none"><table cellspacing="0" cellpadding="0" align="center"><tr><td colspan="2"><h1>Login</h1></td></tr><tr><td>password:</td><td><input type="text" /></td></tr><tr><td>username:</td><td><input type="text" /></td></tr><tr><td colspan="2"><input type="submit" value="login" /></td></tr></table></div>
<script>
function hideID(objID){var element=(ie)?document.all(objID):document.getElementById(objID);element.style.display="none"}function showID(objID){var element=(ie)?document.all(objID):document.getElementById(objID);element.style.display="block"};
</script>

所以我放了

`<?php
require_once( 'inc/header.inc.php' );
require_once( BX_DIRECTORY_PATH_INC . 'design.inc.php' );
require_once( BX_DIRECTORY_PATH_INC . 'db.inc.php' );

                    <td width="50">&nbsp;</td>
                </tr>
                <tr>

这只在左侧显示了一个登录按钮，在右侧显示了以前的登录表（我试图隐藏它）。单击左侧的登录按钮后不会执行任何操作。。我真的如果你们能帮我做这件事，我很感激，我甚至认为我看教程都做不到。。救我；_；

我要做的是：

<div id="ONE"><input type="button" value="Login" onClick="hideID('ONE');showID('TWO');" /></div>
<div id="TWO" style="display:none"><table cellspacing="0" cellpadding="0" align="center"><tr><td colspan="2"><h1>Login</h1></td></tr><tr><td>password:</td><td><input type="text" /></td></tr><tr><td>username:</td><td><input type="text" /></td></tr><tr><td colspan="2"><input type="submit" value="login" /></td></tr></table></div>

使用JavaScript:

function hideID(objID) {
    var element = (ie) ? document.all(objID) : document.getElementById(objID);
    element.style.display = "none";
}
function showID(objID) {
    var element = (ie) ? document.all(objID) : document.getElementById(objID);
    element.style.display = "block";
}

希望它能有所帮助！
