Have you included the jQuery library in your page, and put that line changing the value in the correct place?
您是否在页面中包含了 jQuery 库，并将更改值的那一行放在正确的位置？
Something like this:
像这样的东西：
<script type="text/javascript" src="location/of/jquery.js"></script>
<script type="text/javascript">
$(function() {
$("#hidden_input").val('test');
});
</script>
