Modifying webpage design using JavaScript for styling

Is there a way to change the css style(defined in the page source) dynamically with Java? I know it is possible to do it with JavaScript. If there isn't, are there other situations where JavaScript is the only choice developing a web app?

Answer №1

Matthew brings up a good point. It would be beneficial to clarify the question further.

If you are referring to an applet running on the current page, you have the ability to execute any JavaScript, including code that modifies the style of elements.

To do this, simply add the "mayscript" attribute to the applet tag and use code similar to the example below: JSObject window = (JSObject) JSObject.getWindow(this); window.eval("document.getElementById('myelem').style='border-color: red';");

If your inquiry involves servlets/JSPs, there are two options available: 1. Generate complete HTML with embedded CSS. 2. Connect a style element to a URL mapped to a servlet or JSP responsible for generating CSS dynamically.

This approach leads us to a styles URL linked to a servlet that generates CSS on-the-fly based on the specified "id" parameter.

I hope this information proves useful. If not, please provide additional details in order to address your query more accurately.
