Requesting a Webroutine
The Lstd.Json.getWebroutine(options) method provides a way for your JavaScript code to call a Webroutine. Any webrouting can be called with this method but only a JSON Response Webroutine can return data to it. The single options parameter is a JavaScript object containing zero or more of the following properties:
Wam |
The WAM being called. If not present, the current WAM is used. |
|---|---|
webroutine |
The Webroutine being called. If not present, the current webroutine is used. |
Fields |
A JavaScript object containing the input values to send to the Webroutine. For example: |
Lists |
A JavaScript object containing lists to send to the Webroutine. Each list is an array or rows and each row is an object containing column values. For example: |
callback |
A JavaScript function that will be called when the Ajax request is completed. This function is only called on successful completion of a call to a JSON Response Webroutine. It will be passed a single parameter containing a Webroutine object that represents the Webroutine output. |
|
Putting it all together, you get something like this:
/* * Get webroutine (Ajax request) * Webroutine (wr) is passed to the callback wrapped in an Lstd.Json.Wr object */ var options = { wam: "SampleWam", webroutine: "Sample1", fields: { GIVENAME: "John",
SURNAME: "Smith" }, lists: { LIST01: [ {DEPTMENT: "ADM", DEPTDESC: "Administration"}, {DEPTMENT: "FIN", DEPTDESC: "Finance"} ] }, callback: function(wr) { // Code to handle the Ajax response goes here } }; Lstd.Json.getWebroutine(options);
The Webroutine object passed to the callback function contains a number of methods for getting the fields and lists returned from the server.
