Question

大家好，我很难弄清楚什么是错的。所以我有一个电子邮件发送表单复选框和复选框限制，但是，它无法正常工作。这是复选框限制脚本。

    <script type="text/javascript">
    function chkcontrol(j) {
    var total=0;
    for(var i=0; i < document.form1.ckb.length; i++){
    if(document.form1.ckb[i].checked){
total =total +1;}
if(total > 3){
alert("Please Select only three") 
document.form1.ckb[j].checked = false ;
return false;
}
}
} </script>

这是表格

<form name="form1" method="post" action="send_form_email2.php">

这是php电子邮件表单

<?php
error_reporting(-1);
ini_set('display_errors', 'On');
if(isset($_POST['email'])) {
$cbk = array();

// EDIT THE 2 LINES BELOW AS REQUIRED
$email_to = "info@samplebox.eu";
$email_subject = "Contact form";
$email_from = "";

$email_message = "Form details below.\n\n";

function clean_string($string) {
$bad = array("content-type","bcc:","to:","cc:","href");
return str_replace($bad,"",$string);
}

$email_message .= "Vardas: ".clean_string($_POST["name"])."\n";
$email_message .= "El. Pastas: ".clean_string($_POST["email"])."\n";
$email_message .= "Telephone: ".clean_string($_POST["telephone"])."\n";
$email_message .= "Produktai: ".implode(" ", $_POST['ckb'])."\n";
$email_message .= "Comments: ".clean_string($_POST["comments"])."\n";


// create email headers
$headers = 'From: '.$email_from."\r\n".
'Reply-To: '.$email_from."\r\n" .
'X-Mailer: PHP/' . phpversion();
mail($email_to, $email_subject, $email_message, $headers); 
?>

<!-- include your own success html here -->
<center>
<img src="images/logo.png" />
<br>
<br>
Greitai susisieksime<br>
<br>
<a href="index.html">Namai</a></center>
<?php
}
?>

当选中这些复选框时，当您点击提交按钮时，我会收到一封包含所有信息的电子邮件，除非它没有显示选中的复选框。

任何人都可以帮我吗？ :) 编辑：这是

中的以下代码

<script type="text/javascript">
var myForm = document.forms.form1;
var allInputs= myForm.elements['ckb[]'];


var len = allInputs.length;

for (var i = 0; i < len; i++)

function chkcontrol(j) {
var total=0;
for(var i=0; i < document.form1.ckb.length; i++){
if(document.form1.ckb[i].checked){
total =total +1;}
if(total > 3){
alert("Please Select only three") 
document.form1.ckb[j].checked = false ;
return false;
}
}
}
} </script>

Answer 1

谷歌搜索后，我发现有人试图做类似的事情。我想你需要改变

name=ckb

到

name=ckb[]

所以php会知道＆＃34; ckb＆＃34;确实是一系列复选框。希望这有助于

发表你的评论试试这个：

var allInputs = document.form1.elements['ckb[]'];


var len = allInputs.length;

for (var i = 0; i < len; i++)
   your code here
}

我们聊了很多，结果发现html本身有一些问题，并没有调用这些函数，但上面的代码毕竟是有用的。
