HTML实体解码

您可以尝试类似：

var Title = $('<textarea />').html("Chris&apos; corner").text();console.log(Title);<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

更具交互性的版本：

$('form').submit(function() {  var theString = $('#string').val();  var varTitle = $('<textarea />').html(theString).text();  $('#output').text(varTitle);  return false;});<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script><form action="#" method="post">  <fieldset>    <label for="string">Enter a html-enpred string to depre</label>    <input type="text" name="string" id="string" />  </fieldset>  <fieldset>    <input type="submit" value="depre" />  </fieldset></form><div id="output"></div>
