<h:outputScript target="head">
    function myfun(){

JSF runs in webserver and generates HTML. Webserver sends it to webbrowser. JavaScript runs in webbrowser and all it sees/understands is HTML only.

Open the JSF page in browser. Rightclick and View Source. Locate the HTML <input type="text"> element which is generated by JSF <h:inputText>. Look at its id attribute. It’ll look something like this

<input type="text" id="formid:myfield" />

You need to use exactly that ID in the JavaScript.

alert($('#formid\\:myfield').val());
