XSLTForms/Javascript

Warning!! This documentation is automatically generated from embedded comments in Javascript sources. XSLTForms Javascript parts are activated just after the XSLT transformation performed by the browser. The "init()" function is created by the XSLT transformation according to the XForms document, with "xforms.init()" as the last function call, and called by the "onload" event associated with the "body" element. Many Javascript objects and functions can be called directly by developers for specific purposes considering that misuse can compromise the XSLTForms global behavior. Main functions and objects "$" function Shortcut for document.getElementById() How does this work if we also want to include JQuery functions. Should a different function be used?
