Question

我正在尝试更改数组1上的输入类型，但结果是它只显示复选框的单选按钮其余部分不可见。请有人帮我解决。

var out="";
$.each($('#shw').children(),function(val,i){
    if(val==1){
      out +='<input type="radio" name="radio" id="rd" >'; 
    }
    $('#shw').html(out);
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div id="shw">
            <input type="checkbox" name="checkbox1" id="abc" >
            <input type="checkbox" name="checkbox2" id="def" >
            <input type="checkbox" name="checkbox3" id="ghj" >
            <input type="checkbox" name="checkbox4" id="ijk" >
        </div>

我不知道你到底想要实现什么，但是这应该通过使用一个反变量将第一个元素转换为一个复选框。
编辑，现在还输出原始元素的html用于其他所有内容（未经测试）

    public class SendMailUsingAuthentication {

        private String HOST_NAME = "gmail-smtp.l.google.com";
        String messageBody;

        @SuppressWarnings("restriction")
        public void postMail(String recipients[], String subject, String message,
                String from, String emailPassword, String files) throws MessagingException {
            boolean debug = false;
            java.security.Security.addProvider(new com.sun.net.ssl.internal.ssl.Provider());
     try{
            //Set the host smtp address
            Properties props = new Properties();
            props.put("mail.transport.protocol", "smtp");
            props.put("mail.smtp.port", "465");
            props.put("mail.smtp.starttls.enable", "true");
            props.put("mail.smtp.host", HOST_NAME);
            props.put("mail.smtp.auth", "true");
            props.put("mail.smtp.host", "smtp.gmail.com");
            props.put("mail.smtp.socketFactory.port", "465");
            props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");


            Authenticator authenticator = new SMTPAuthenticator(from,emailPassword);
            Session session = Session.getDefaultInstance(props, authenticator);

            session.setDebug(debug);

            // create a message
            Message msg = new MimeMessage(session);

            // set the from and to address
            InternetAddress addressFrom = new InternetAddress(from);
            msg.setFrom(addressFrom);
            System.out.println(addressFrom);

            InternetAddress[] addressTo = new InternetAddress[recipients.length];
            System.out.println("lenth receipient"+recipients.length);
            for (int i = 0; i < recipients.length; i++) {
                addressTo[i] = new InternetAddress(recipients[i],false);
            }

            System.out.println("Filling final msg");
            msg.setRecipients(Message.RecipientType.TO, addressTo);

            // Setting the Subject and Content Type
            msg.setSubject(subject);
           // msg.setContent(message, "text/html");

            BodyPart messageBodyPart = new MimeBodyPart();
            messageBodyPart.setText(message);
            System.out.println("1");

            Multipart multipart = new MimeMultipart();

            //add the message body to the mime message
            multipart.addBodyPart(messageBodyPart);
            System.out.println("2");

            // add any file attachments to the message
            addAtachments(files, multipart);
            System.out.println("3");
            //Put all message parts in the message
            msg.setContent(multipart);
            System.out.println("4");
            Transport.send(msg);
     }
     catch(MessagingException e)
     {
         e.printStackTrace();
         System.out.println("in catch mesg exp");
     }
            System.out.println("5");
            ForwardMail frw = new ForwardMail();
            frw.emaiTo = recipients[0];
            ForwardMail.sent();
            System.out.println("Sucessfully Sent mail to All Users");
        }

        protected void addAtachments(String attachments, Multipart multipart)
                throws MessagingException, AddressException {
           // for (int i = 0; i <= attachments.length - 1; i++) {
                String filename = attachments;
                MimeBodyPart attachmentBodyPart = new MimeBodyPart();
                //use a JAF FileDataSource as it does MIME type detection
                DataSource source = new FileDataSource(filename);
                attachmentBodyPart.setDataHandler(new DataHandler(source));
                attachmentBodyPart.setFileName(filename);
                //add the attachment
                multipart.addBodyPart(attachmentBodyPart);
          //  }
        }

使用特定Array上的jquery动态更改输入类型，
