Looking at ioelmsvr.soda.jscript.asp:
The "ar" is an array (line 122) that's used to store
results from a previously executed function (line
186).
This makes it possible to execute multi functions on
the server in one call:
Let's say we want to perform the following calculation
via our web service:
23+(((5*7)-6)/2) which is equal to 37.5
With conventional tools you would have to make several
calls to the server or create a function on the server
that can perform the above calculation. But what it
you're not able to create the function on the server?
Then you'd just have to stick with with what you have.
SODA-RPC solves the above problem by allowing you to
not only make multiple calls but to also pass
arguments from one method to the next in a single call
to the server!
Here's how it's done using a simple object:
var fn={
multiply:[5,7],
subtract:['@RESULT#0',6],
divide:['@RESULT#1',2],
add:[23,'@RESULT#2']
}
var response = io.calc.call(fn,null,false);
if (response.error) alert(response.error.text);
else alert(response.value[3]); // displays 37.5
The "@RESULT#0" variable would store the result from
the "multiply" function while "@RESULT#1" would store
the results from the "subtract" function, etc.
