我是 javascript 的完全新手。我的网站上有一些 js 正在处理隐藏表单中的一些 div。我想更改表单的某些值，并且对 javascript 的某些语法感到困惑。这是我正在使用的 html 和脚本：
<div class="outeremailcontainer">
<div id="emailcontainer">
<?php include('verify.php'); ?>
<form action="../index_success.php" method="post" id="sendEmail" class="email">
<h3 class="register2">Newsletter Signup:</h3>
<ul class="forms email">
<li class="name">
<label for="yourName">Name: </label>
<input type="text" name="yourName" class="info" id="yourName" value="<?php echo $_POST['yourName']; ?>" /><br />
</li>
<li class="city"><label for="yourCity">City: </label>
<input type="text" name="yourCity" class="info" id="yourCity" value="<?php echo $_POST['yourCity']; ?>" /><br />
</li>
<li class="email">
<label for="emailFrom">Email: </label>
<input type="text" name="emailFrom" class="info" id="emailFrom" value="<?php echo $_POST['emailFrom']; ?>" />
<?php if(isset($emailFromError)) echo '<span class="error">'.$emailFromError.'</span>';
?>
</li>
<li class="buttons email">
<button type="submit" id="submit">Send</button>
<input type="hidden" name="submitted" id="submitted" value="true" />
</li>
</ul>
</form>
<div class="clearing">
</div>
</div>
</div>
和脚本：
<script type="text/javascript">
$(document).ready(function(){
$('#emailFrom')
.focus(function(){
if ($('#overlay').length) { return; } // don't keep adding overlays if one exists
$('#sendEmail')
.find('.name, .city').slideDown(300, function(){ $(this).show(); });
$('.outeremailcontainer').css({ position: 'relative', bottom: 0, left: 0, zIndex: 1001 });
$('<div id="overlay"></div>').appendTo('body');
});
$('#overlay').live('click', function(){
$('#sendEmail')
.css({ backgroundColor : 'transparent' })
.find('.name, .city').slideUp(300);
$('.outeremailcontainer').css({ position : 'static' });
$('#overlay').remove();
});
});
页面底部还有一个脚本包含：
$(document).ready(function(){
$('#emailFrom')
.focus(function(){
if ($('#overlay').length) { return; } // don't keep adding overlays if one exists
$('#sendEmail')
.find('.name, .city').slideDown(300, function(){ $(this).show(); });
$('.outeremailcontainer').css({ position: 'relative', bottom: 0, left: 0, zIndex : 1001 });
$('<div id="overlay"></div>').appendTo('body');
});
$('#overlay').live('click', function(){
$('#sendEmail')
.css({ backgroundColor : 'transparent' })
.find('.name, .city').slideUp(300);
$('.outeremailcontainer').css({ position : 'static' });
$('#overlay').remove();
});
});
$(document).ready(function(){
$("#submit").click(function(){
$(".error").hide();
var hasError = false;
var emailReg = /^([\w-\.]+@([\w-]+\.)+[\w-]{2,4})?$/;
var emailFromVal = $("#emailFrom").val();
if(emailFromVal == '') {
$("#emailFrom").after('<span class="error"><br />You forgot to enter the email address to send from.</span>');
hasError = true;
} else if(!emailReg.test(emailFromVal)) {
$("#emailFrom").after('<span class="error"<br />>Enter a valid email address to send from.</span>');
hasError = true;
}
var yourNameVal = $("#yourName").val();
if(yourNameVal == '') {
$("#yourName").after('<span class="error"><br />You forgot to enter your name.</span>');
hasError = true;
}
var yourCityVal = $("#yourCity").val();
if(yourCityVal == '') {
$("#yourCity").after('<span class="error"><br />You forgot to enter your city.</span>');
hasError = true;
}
if(hasError == false) {
$(this).hide();
$("#sendEmail li.buttons").append('<img src="/wp-content/themes/default/images/template/loading.gif" alt="Loading" id="loading" />');
$.post("/includes/sendemail.php",
//emailTo: emailToVal,
{ emailFrom: emailFromVal, yourName: yourNameVal, yourCity: yourCityVal },
function(data){
$("#sendEmail").slideUp("normal", function() {
$("#sendEmail").before('<h3 class="register2">Thank you! You\'re on the email list!</h3><p class="emailbox">Click <a href="xxx">HERE</a> for your free song.</p>');
});
}
);
}
return false;
});
});
上面的代码一切正常。但是，我想对一些不同的变量使用不同的表单操作。代码的表单部分需要如下所示：
<div class="outeremailcontainer">
<div id="emailcontainer">
<?php include('verify.php'); ?>
<form action="https://madmimi.com/signups/subscribe/66160" method="post" id="mad_mimi_signup_form" class="email">
<h3 class="register2">Newsletter Signup:</h3>
<ul class="forms email">
<li class="name">
<label for="signup_name">Name: </label>
<input type="text" name="signup[name]" class="info" id="signup_name" value="<?php echo $_POST['signup_name']; ?>" /><br />
</li>
<li class="city"><label for="signup_city">City: </label>
<input type="text" name="signup[city]" class="info" id="signup_city" value="<?php echo $_POST['signup_city']; ?>" /><br />
</li>
<li class="email">
<label for="signup_email">Email: </label>
<input type="text" name="signup[email]" class="required" id="signup_email" value="<?php echo $_POST['signup_email']; ?>" />
<?php if(isset($emailFromError)) echo '<span class="error">'.$emailFromError.'</span>';
?>
</li>
<li class="buttons email">
<button type="submit" id="webform_submit_button">Send</button>
<input type="hidden" name="submitted" id="submitted" value="true" />
</li>
</ul>
</form>
<div class="clearing">
</div>
</div>
</div>
我不知道我需要更改哪些 js 代码才能使 div 隐藏操作仍然使用新值。有人能帮忙吗？谢谢！
