I'm writing a script to generate a control panel form an XML file and
I'm having trouble when attempting to attach events using
Event.observer.
An example node in my XML file looks like this:
<control ... >
<function action="click" do="doSomething" />
</control>
where "click" is the event and "doSomething" is the name of a
javascript function I have defined elsewhere.
My javascript looks something like this (the control nodes have already
been appended to the DOM as <a href..>'s):
var controls = $A(XML.getElementsByTagName("control"));
controls.each(function(node) {
var nFunctions =
$A(node.getElementsByTagName("function"));
nFunctions.each(function(fun){
Event.observe(node.getAttribute("id"),fun.getAttribute("action"),fun.getAttribute("do"))
});
});
I know the problem is with the last argument in Event.observe because
if I change the last argument to an anonymous function it works. It
also works if I change the last argument so that it is the name of the
function. These both work:
Anonymous function:
Event.observe(node.getAttribute("id"),fun.getAttribute("action"),function(e){alert(e);})
Name of function:
Event.observe(node.getAttribute("id"),fun.getAttribute("action"),doSomething)
This is the error I'm getting:
[Exception... "Could not convert JavaScript argument" nsresult:
"0x80570009
(NS_ERROR_XPC_BAD_CONVERT_JS)" location: "JS frame::
http://.../prototype.js :: anonymous :: line 1969" data: no]
Any help greatly appreciated. Thanks!
