使用FeatherLight打开后无法更改/获取输入值?

我遇到了一种奇怪的行为。我正在尝试获取/设置输入文本框的值 关闭FeatherLight灯箱后。当我尝试获取文本框的值时(在通过Featherlight打开和关闭它之后),我得到“Undefined”。你可以在这里看到我的源代码:

唯一相关的部分是html代码。尝试在JSFiddle上运行代码并查看输入的值(文本框的值)。关闭Featherlightbox后,您会看到“未定义”。这是html:

<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<script type="text/javascript">
var storeData = null;

function openFeatherLight()
 {
  if (!storeData)
   {
    storeData = $.featherlight($('#MyDiv'), { 'persist' : true , 'beforeOpen' : sayHi , 'beforeClose' : sayBye, 'afterClose' : changeInputValueAfterClose });
   }
  else
   {
    storeData.open();
   }  
 }

function sayHi()
 {
  alert('Value of textbox BEFORE opening FeatherLight LightBox Is: ' + $('#MyTextBox').val());
 }

function sayBye()
 {
  alert('Value of textbox BEFORE CLOSING the FeatherLight LightBox Is: ' + $('#MyTextBox').val());
 }

function changeInputValueAfterClose()
 {
  $('#MyTextBox').val("Bla");
  alert('Current Value Of Input TextBox After Change is: ' + $('#MyTextBox').val());
  alert('We get "Undefined". Why?');
 }

</script>
</head>
<body>
<div id="Shit" style="display: none;">
<div id="MyDiv">
Text
<form id="MyForm">
<input type="text" value="Initial_Value_Set_By_Me_For_Testings" id="MyTextBox">
</form>
</div>
</div>
<input name="Button1" type="button" value="Open FeatherLight" class="AddToMenuButton" onclick="openFeatherLight();">
</body>
</html>

答案 0 :(得分:1)

第一次之后,DOM元素仍然分离(有一天我打开它重新插入......)。因此$('#MyTextBox')之后无效。要么保留对它的引用,要么使用storeData.$content.find('#MyTextBox')
