You can like this:
你可以喜欢这个：
<h:inputText id="propertyId" value="#{myBean.property}" style="display:none"/>
and access it like this (note that if its inside a form you might need to add the form prefix)
并像这样访问它（请注意，如果它在表单中，您可能需要添加表单前缀）
alert($('#propertyId').val()); // or alert($('#myFormId\:propertyId').val());

I guess you want it to be updated to the current value inside the bean. You can't! You can only add it to javascript during load time. If you want it to be updated you will have to do ajax calls to fetch the current value.
我猜您希望它更新为 bean 内的当前值。你不能！您只能在加载期间将其添加到 javascript。如果您希望它被更新，您将不得不执行 ajax 调用来获取当前值。
