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: { GIVENAME: "William", SURNAME: "Shakespeare" } |
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: { LIST01: [ {DEPTMENT: "ADM", DEPTDESC: "Administration"}, {DEPTMENT: "FIN", DEPTDESC: "Finance"} ] } |
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.
