/* * From: http://forum.java.sun.com/thread.jspa?forumID=45&threadID=550658 * * Note: The JavaScript functions called 'vfnOnLoad' and 'vfnOnUnLoad' will * be called automatically on all pages using SubMenuLayout.jsp. Page parts * should not overwrite these functions, but instead, register a function * to be called by passing the name of the function to call on load/unload a * as a string to 'vfnRegOnLoad' and 'vfnRegOnUnLoad'. All functions will * then be called at the appropriate time, in the order registered. * For example: vfnRegOnLoad('myOnloadFunction();'); Example: Then in the single body, I have this: And in my tiles, if I want to have something run on load, I just do this: This way you can have multiple things register to call on load or unoad from any tile. */ var aOnLoadFunctions = new Array(); var aOnUnLoadFunctions = new Array(); vfnOnLoad = function() { if(aOnLoadFunctions.length != 0) { for(var i = 0; i < aOnLoadFunctions.length; i++) { eval(aOnLoadFunctions[i]); } } } vfnOnUnLoad = function() { if(aOnUnLoadFunctions.length != 0) { for(var i = 0; i < aOnUnLoadFunctions.length; i++) { eval(aOnUnLoadFunctions[i]); } } } vfnRegOnLoad = function(sFunc) { if(typeof(sFunc) != 'undefined' && sFunc != null && sFunc != '') { aOnLoadFunctions[aOnLoadFunctions.length] = sFunc; } } vfnRegOnUnLoad = function(sFunc) { if(typeof(sFunc) != 'undefined' && sFunc != null && sFunc != '') { aOnUnLoadFunctions[aOnUnLoadFunctions.length] = sFunc; } }
