JSF-generated HTML element ID is changing, how to

问题:

I have a JSF input text component which has an id of search. In the generated HTML output it looks like this j_idt17:search, but the number 17 is changing from time to time. How to make it to stay one?

回答1:

Give the JSF component which generated the HTML element with id="j_idt17" a fixed ID. In this particular case, it's likely the HTML input element's parent <form> element which is generated by the JSF <h:form> component.

So, this should do:

<h:form id="form">

This way the ID of the generated HTML <input> element will become form:search.
