Where is jsf js

This can point out the head, the body or the form. See the original article here. Thanks for visiting DZone today,. Edit Profile. Sign Out View Profile. Over 2 million developers have joined DZone. You may want to use the h:outputScript tag to specify other JavaScript libraries. In order to use a JavaScript resource directly with a UIComponent , you must explicitly load the resource in either of the following ways:.

By using the javax. To use the bundled JavaScript resource API directly in a web application, such as a Facelets page, you need to first identify the default JavaScript resource for the page with the help of the h:outputScript tag.

For example, consider the following section of a Facelets page:. Specifying the target as head causes the script resource to be rendered within the head element on the HTML page. In the next step, identify the component to which you would like to attach the Ajax functionality. This is how the JSF engine knows which particular component does the postback and to invoke at the server side actions appropriately.

The scrpt below illustrates how to inject a line of code to open a confirm dialog window, and the resulting HTML:. Another important point to note is that the javascript block should not return true under any circumstance. The command button is a little simpler. If the javascript block returns true then the form is submitted as usual. If it returns false then the form submission is aborted.

The key to successful javascripting with JSF is to understand what is being rendered. Some basic understanding of javascipt goes a long way as well. Also be extra careful with the syntax, as most IDE do not have any support for Javascript. If you made a syntax error - for example missing out a closing bracket, your codes will simply fail silently. It is quite often that you may want to submit immediately from a control combo box changes, radio button is selected, etc.

Just because you send something to the server that looks like a filepath doesn't mean that it will return a file. That's why they're called Uniform Resource locators and not File locators. Well, I got the answer : it is located inside jsf-impl. Proving once again that as long as I work with computers I need never worry about if I'll end up looking like an idiot.

It's dangerous to "know" things in a field where everything's always changing. It doesn't exist in JSF1.
