从输入字段读取属性时，HTML编码丢失

问题：

I'm using JavaScript to pull a value out from a hidden field and display it in a textbox. 我正在使用JavaScript从隐藏字段中提取值并将其显示在文本框中。 The value in the hidden field is encoded. 隐藏字段中的值被编码。

For example, 例如，

<input id='hiddenId' type='hidden' value='chalk &amp; cheese' />

gets pulled into 被拉入

<input type='text' value='chalk &amp; cheese' />

via some jQuery to get the value from the hidden field (it's at this point that I lose the encoding): 通过一些jQuery从隐藏字段中获取值（此时我失去了编码）：

$('#hiddenId').attr('value')

The problem is that when I read chalk & cheese 问题是，当我阅读chalk & cheese chalk & cheese from the hidden field, JavaScript seems to lose the encoding. 从隐藏字段起， chalk & cheese似乎失去了编码。 I do not want the value to be chalk & cheese . 我不希望这个价值是chalk & cheese 。 I want the literal amp; 我想要文字amp; to be retained. 被保留。

Is there a JavaScript library or a jQuery method that will HTML-encode a string? 是否有将对字符串进行HTML编码的JavaScript库或jQuery方法？
