jQuery Facebox:发送空输入字段值

时间:2010-09-05 10:53:46

标签: jquery jquery-plugins facebox

我的jQuery有facebox插件,为我制作灯箱。 我点击了一个链接,然后就会出现一个朋友请求表单。

单击“发送请求”时,表单会生成一个ajaxcall,但是这两个字段不会发送您在其中写入的内容,它只会发送空值。

但如果它不在facebox灯箱内,那么它可以工作并在ajax调用中发送值。

因此,facebox.js中的某些内容会阻止这些字段并向其发送空值。

我该如何解决这个问题?

这是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> \
          <tbody> \
            <tr> \

            </tr> \
            <tr> \
              <td class="b"/> \

                  </a> \
                </div> \

这是我的表格,即使我怀疑这里有什么不对,因为它在盒子外面工作:

                <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>

问题在于这一行:

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

它正在克隆您的元素,特别是id="messageFriend"id="commentFriend",这会导致问题,因为它们假设是唯一的。 #ID selector找到的原始元素仍为空(克隆的元素具有您所追求的值)。

要解决此问题, 我会删除id属性,然后通过name找到它们......然后只找到:visible个,这将是当前打开的facebox,如下所示:

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,看一下控制台,看它确实现在正在提交值。

尝试:

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