Change html content with jstl or scriptlet

I know that you can use javascript inner html to change the content of the HTML code inside a <div> tag. But is there anyone here who know of a way to change the content of HTML using other lang开发者_如何学Gouages such as JSTL or scriptlets?

I assume that you're fully aware that Java/JSP/JSTL runs at webserver and produces HTML/CSS/JS and that HTML/CSS/JS runs at the webbrowser. Thus, Java/JSP/JSTL has totally no notion of the client side HTML DOM tree like as JS has access to by the document object. But Java/JSP/JSTL can be used to control the rendering of the HTML/CSS/JS output.

You could use JSTL and/or EL to conditionally display blocks of HTML/CSS/JS. E.g.

<div>
    <c:if test="${condition1}">
        <p>This block will only be rendered when condition1 evaluates true.</p>
    </c:if>
    <c:if test="${condition2}">
        <p>This block will only be rendered when condition2 evaluates true.</p>
    </c:if>
</div>

Using scriptlets is discouraged since JSP 2.0 (2003). So don't even think about it.
