utilizing javascript function in Icefaces applications

I'm facing an issue. Here's the situation: I'm working on a quiz game where I need to implement a timer using JavaScript (jquery.timer.js). I have created a JavaScript file (question.js) with a method called startTimer, which utilizes the jquery.timer.js function to display the timer on the screen.

When the user clicks on the answer button, I call a managed bean method to validate their answer. If the answer is correct, I update the question on the screen.

My Questions: 1) How can I include both JavaScript files (question.js and jquery.timer.js)? 2) How can I execute the startTimer function when the form loads or when the question changes on the screen?

Additional Information: I am working with facelets and need to implement the above in myquiz.xhtml which utilizes the ui:composition tag.

Can anyone provide assistance with this situation?

Any help would be greatly appreciated.

Thanks & Regards, Rajeshwar

Answer №1

1) Is there a way to add both question.js and jquery.timer.js into the h:head section of my page?

I want to insert these two scripts inside the h:head element:

<script type="text/javascript" src="question.js"/>
<script type="text/javascript" src="jquery.timer.js"/>

How can I trigger the js function (startTimer) when the form loads?

If you are unsure, you can utilize JavascriptContext to execute javascript code on page load. In your bean, when you are preparing to display the next question, you can use the following code:

JavascriptContext.addJavascriptCall(FacesContext.getCurrentInstance(), "call your function();");

Answer №2

To address the first point, I recommend using the following code:

<h:outputScript library="js" name="question.js" location="head"/>
<h:outputScript library="js" name="jquery.timer.js" location="head"/>

For the second point, on page load simply include:

<script type="text/javascript">
/* <![CDATA[ */
window.onload = function(){
    yourFunction();
};
/* ]]> */
</script>

If not on page load, you can opt for using 

JavascriptContext.addJavascriptCall
as user FS recommended.
