Getting DOM element from JavaScript using RichFaces 4
dom, getelementbyid, javascript, richfaces
Solution
I suggest you to read this article: RichFaces built-in client functions
To summarize, there are 4 built in function:
- `#{rich:clientId('id')}`
- `#{rich:element('id')}`
- `#{rich:component('id')}`
- `#{rich:findComponent('id')}`
Explanation:
- The first one permit to convert richfaces id to string.
- The second one is used to `getElementById` (HTML Element)
- The third one is used to `getElementById` (JavaScript Component)
- The last to get value without a call to the managedBean
Problem
I am currently studying a migration to RichFaces 4. From my JS, I have have to get DOM elements using ``` document.getElementById('myParent:myElement'). ``` From the JBoss migration guide, I understood that "document.getElementById" can no longer be used : https://community.jboss.org/wiki/RichFacesMigrationGuide33x-4xMigration-CommonComponentsChanges. Can somebody explain me why, and how can I (simply) change all my calls to this function - over a thousand - to something else ? Thanks.
