We can rename load() to get() and add the data parameter. But I disagree that we
should be the ones who decide what the varible is named when there is nothing gained
by doing so. Instead we can always use a data object, where the variable names are
arbitrary:
var data = {
name : "My Name",
number : 2,
array : (1,2,3)
}
io.get('script.asp',data,fn);
This would serialize the object and load the url as:
url.asp?name=My%20Name&number=2&array=1,2,3
This way you are not forced to code your ASP/Perl/PHP code in any particular manner.
Except for maybe transferring an array where you'd probably need to unencode it within
the server script.
The same goes for retrieving data from the page, have no default variable, and l
et the developer choose the variable name:
var myResult = "success"; // generate on server
e.getSource().getVariable('myResult'); // obtain in load handler
For an intermediate version we can just support numbers and strings. But for anything
much more complex than arrays (like linked lists, and multidimensional arrays), we
should forfeit to an XML/RPC based solution because I'd like to keep IOElement a small
and easy communication scheme.
