This is not HTML, it is a JSTL-Tag.

The code <c:if will be evaluated by the server (glassfish/tomcat) while producing the HTML which will be provided to the browser.

The JavaScript code runs in the browser. There is no (simple) way to use JavaScript values to manipulate HTML-rendering.

HTML itself isn't able to work with JavaScript-variables, so the only way is, to set a variable in JavaScript and use the value with JavaScript.

You can set data using jquery and $("#display-button").data("key", "Yes") you can read the data out using $("#dispaly-button").data("key") -> returns "Yes"
