Question

我有一张表格

<form id="post_comment" action="cmt.php" method="post">
   <input type="hidden" name="type" value="sub" />
   <textarea id="body"></textarea>
</form>

我正在使用此代码访问表单

$("#post_comment").submit(function(event){

    var form = $(this);

});

如何从此表单中获取<input type="hidden" name="type" value="sub" />的值。我试图使用form.input("type")，但它无效。

Answer 1

$("#post_comment").submit(function(event){
    var inputValue = $("input[name='type']",this).val(); 
});

Answer 2

尝试使用这样的ID：

<form id="post_comment" action="cmt.php" method="post">
 <input type="hidden" id='hidden' name="type" value="sub" />
 <textarea id="body"></textarea>
</form>

以后：

$("#post_comment").submit(function(event){
 var hiddenValue = $("#hidden").val(); 
});

Answer 3

var form = $(this);
var inputValue =  form.find('input[name="type"]').val();

or 

var form = $(this);
var inputValue =  form.find('input:hidden').val();

Answer 4

<form id="post_comment" action="" method="post">
 <input type="hidden" class="hidden" name="type" value="sub" />
 <textarea id="body"></textarea>
 <input type="submit" value="submit" class="submit"/>
</form>



 $(".submit").click(function(){
   var hiddenVal=jQuery("#post_comment .hidden").val();
   //alert(hiddenVal);
 });

另一种方法
考虑一下，如果您具有多个表单，并且多个输入字段具有名称属性，则此代码对您有帮助：

<?php
$username = 'username';
$password = 'password';

$url = "your url";

$ch = curl_init();
curl_setopt($ch,CURLOPT_URL, $url);
curl_setopt($ch,CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch,CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($ch,CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch,CURLOPT_FOLLOWLOCATION, false);
curl_setopt($ch,CURLOPT_TIMEOUT, 30);
curl_setopt($ch,CURLOPT_CONNECTTIMEOUT, 30);
curl_setopt($ch,CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_HEADER, 1);
$first_response = curl_exec($ch);
$info = curl_getinfo($ch);

preg_match('/WWW-Authenticate: Digest (.*)/', $first_response, $matches);

if(!empty($matches))
{
  $auth_header = $matches[1];
  $auth_header_array = explode(',', $auth_header);
  $parsed = array();

  foreach ($auth_header_array as $pair)
  {
    $vals = explode('=', $pair);
    $parsed[trim($vals[0])] = trim($vals[1], '" ');
  }

  $response_realm     = (isset($parsed['realm'])) ? $parsed['realm'] : "";
  $response_nonce     = (isset($parsed['nonce'])) ? $parsed['nonce'] : "";
  $response_opaque    = (isset($parsed['opaque'])) ? $parsed['opaque'] : "";

  $authenticate1 = md5($username.":".$response_realm.":".$password);
  $authenticate2 = md5("POST:".$url);

  $authenticate_response = md5($authenticate1.":".$response_nonce.":".$authenticate2);

  $request = sprintf('Authorization: Digest username="%s", realm="%s", nonce="%s", opaque="%s", uri="%s", response="%s"',
  $username, $response_realm, $response_nonce, $response_opaque, $url, $authenticate_response);

  $request_header = array($request);
  $request_header[] = 'Content-Type:application/json';

  $ch = curl_init();
  curl_setopt($ch,CURLOPT_URL, $url);
  curl_setopt($ch,CURLOPT_SSL_VERIFYPEER, false);
  curl_setopt($ch,CURLOPT_SSL_VERIFYHOST, false);
  curl_setopt($ch,CURLOPT_RETURNTRANSFER, 1);
  curl_setopt($ch,CURLOPT_FOLLOWLOCATION, false);
  curl_setopt($ch,CURLOPT_TIMEOUT, 30);
  curl_setopt($ch,CURLOPT_CONNECTTIMEOUT, 30);
  curl_setopt($ch,CURLOPT_CUSTOMREQUEST, "POST");
  curl_setopt($ch, CURLOPT_HTTPHEADER, $request_header);

  $result['response']         = curl_exec($ch);
  $result['info']             = curl_getinfo ($ch);
  $result['info']['errno']    = curl_errno($ch);
  $result['info']['errmsg']   = curl_error($ch); 

  var_dump($result);
}
?>

希望对别人有帮助。
