jQuery Facebox：發送空輸入字段值

Question

我有我的jQuery的facebox插件，爲我製作lightbox。 我做了一個鏈接，你點擊，然後出現一個好友請求表單。

當點擊「發送請求」時，表單會發出一個ajaxcall，但是這兩個字段不會發送任何你寫在裏面的東西，它只是發送空值。

但是，如果它不在facebox中，那麼它的工作原理就是在ajax調用中發送值。

因此，facebox.js中的某些內容會阻止這些字段並將它們發送給空值。

我該如何解決這個問題？

這裏的facebox.js：

(function($) { 
    $.facebox = function(data, klass) { 
    $.facebox.loading() 

    if (data.ajax) fillFaceboxFromAjax(data.ajax) 
    else if (data.image) fillFaceboxFromImage(data.image) 
    else if (data.div) fillFaceboxFromHref(data.div) 
    else if ($.isFunction(data)) data.call($) 
    else $.facebox.reveal(data, klass) 
    } 

    /* 
    * Public, $.facebox methods 
    */ 

    $.extend($.facebox, { 
    settings: { 
     opacity  : 0, 
     overlay  : true, 
     loadingImage : 'images/loading.gif', 
     closeImage : 'images/closelabel.png', 
     imageTypes : [ 'png', 'jpg', 'jpeg', 'gif' ], 
     faceboxHtml : '\ 
    <div id="facebox" style="display:none;"> \ 
     <div class="popup"> \ 
     <table> \

       <td class="b"/> \

      <tr> \

這裏是我的形式，即使我懷疑什麼是錯在這裏，因爲它的工作原理外箱：

 <div id="addFriend" style="display: none;"> 
       <div style="float:right; font-size: 14px;">Add <strong><?php echo $showU["full_name"]; ?></strong> as friend </div> 
       <div class="clearfloat"></div> 

<form id="FriendRequest" action="javascript:DoFriendRequest(<?php echo $v["id"]; ?>, <? echo $showU["id"]; ?>)" method="post"> 

     <script type="text/javascript" charset="utf-8"> 
     $(document).ready(function(){ 
    $("label").inFieldLabels(); 
}); 
    </script> 
       <table align="center" width="auto" border="0" cellpadding="5" cellspacing="5" style="margin: auto;"> 
       <tr> 
       <td style="padding: 10px;" align="center"> 
       Comment: </td><td> 
       <span class="field"> 

       <input name="commentFriend" type="text" id="commentFriend" style="height: auto;"value="" size="22"> 
       </span> 
       </td></tr><tr> 
       <td style="padding: 10px;" align="center"> 
       Message: 
       </td><td> 
       <span class="field"> 

       <input name="messageFriend" type="text" id="messageFriend" value="" size="22"> 
       </span> 
       </td> 
       </tr> 
       <tr> 
       <td colspan="2" style="margin: auto; text-align: center;"> 
       <input name="submit" type="submit" id="submit" value="Send request"> 
       </td> 
       </tr> 

       <tr> 
           <td colspan="2" style="margin: auto; text-align: center;"> 
       </td> 
       </tr> 
       </table> 
       </form> 

       <div style="margin: auto; text-align: center; font-size: 16px; font-weight: bold;" id="insert_svar"></div> 
    </div> 

DoFriendRequest（）

function DoFriendRequest(BuID, uID){ 
    $('#submit').attr('disabled', 'disabled'); 
    var wrapperId = '#insert_svar'; 
    $.ajax({ 
     type: "POST", 
     url: "misc/AddFriendRequest.php", 
    data: { 
    mode: 'ajax', 
    BuID : BuID, 
    uID : uID, 
    message : $('#messageFriend').val(), 
    comment : $('#commentFriend').val() 
    }, 
     success: function(msg){ 
     $('#submit').removeAttr('disabled'); 
    $(wrapperId).prepend(msg); 
    $('#FriendRequest').fadeOut('slow'); 
    $('#message').val(""); 
    $('#comment').val(""); 
     } 
    }); 
} 

Answer 1

問題出在這條線上：

$.facebox.reveal($(target).clone().show(), klass) 

它克隆你的元素，特別是id="messageFriend"和id="commentFriend"因爲他們是應該是獨一無二的，這是造成問題。 #ID selector找到原始仍爲空的元素（克隆的元素具有您所要的值）。

要解決此問題， 我會刪除id屬性和name找到他們，而不是...，然後只找到:visible的，這將是當前打開的facebox，像這樣：

function DoFriendRequest(BuID, uID){ 
    $('#submit').attr('disabled', 'disabled'); 
    var wrapperId = '#insert_svar'; 
    $.ajax({ 
    type: "POST", 
    url: "misc/AddFriendRequest.php", 
    data: { 
     mode: 'ajax', 
     BuID : BuID, 
     uID : uID, 
     message : $('input[name=messageFriend]:visible').val(), 
     comment : $('input[name=commentFriend]:visible').val() 
    }, 
    success: function(msg){ 
     $('#submit').removeAttr('disabled'); 
     $(wrapperId).prepend(msg); 
     $('#FriendRequest').fadeOut('slow'); 
     $('#message, #comment').val(""); 
    } 
    }); 
} 

You can try the updated version here，看看控制檯，看看它確實現在提交值。

Answer 2

嘗試：

$("target:last").serialize()
