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.隐藏字段中的值已编码.

例如,

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

被拉进去

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

通过一些jQuery从隐藏字段中获取值(此时我丢失了编码):

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

问题是,当我chalk & cheese从隐藏字段中读取时,JavaScript似乎失去了编码.为了逃避chalk & cheese和amp;,我想编码保留.

是否有一个JavaScript库或jQuery方法将对字符串进行HTML编码？

任何人都知道我为什么会收到以下错误？我启用了调试功能.
