You can use .indexOf()and .substr()like this:
您可以使用.indexOf()并.substr()喜欢这样的：
var val = $("input").val();
var myString = val.substr(val.indexOf("?") + 1)
You can test it out here. If you're sureof the format and there's only one question mark, you can just do this:
你可以在这里测试一下。如果您确定格式并且只有一个问号，您可以这样做：
var myString = $("input").val().split("?").pop();

Assuming you have your hidden input in a jQuery object $myHidden, you then use JavaScript (not jQuery) to get the part after ?:
假设您在 jQuery 对象中有隐藏的输入$myHidden，然后您使用 JavaScript（而不是 jQuery）来获取以下部分?：
var myVal = $myHidden.val ();
var tmp = myVal.substr ( myVal.indexOf ( '?' ) + 1 ); // tmp now contains whatever is after ?

Here's a way:
这里有一个方法：
<html>
<head>
<script src="jquery-1.4.2.min.js" type="text/javascript"></script>
<script type="text/javascript">
$(document).ready(function(){
var value = $('input[type="hidden"]')[0].value;
alert(value.split(/\?/)[1]);
});
</script>
</head>
<body>
<input type="hidden" value="/TEST/Name?3" />
</body>
</html>
