Use JSON
JSON is a string representation of a JavaScript object that can be transmitted over the network. You can use it to pass parameters inside IBM BPM.
An Open Source JavaScript implementation is available to both parse and construct JSON strings. Part of this package is a JavaScript source file called json2.js.
Procedure
Add this file to your toolkit or process application as a server managed file to provide new global methods and objects.
Example
This example illustrates how to taking a List of Complex data structure and building a JSON representation:var newArray = new Array();
{
var newObj = new Object();
for (var property in tw.local.myPurchase[j].propertyNames)
{
var name = tw.local.myPurchase[j].propertyNames[property];
newObj[name] = tw.local.myPurchase[j][name];
} newArray.push(newObj);} log.error("jsonText = " + jsonText);
Within a browser or the coach, you can use the Dojo classes to work with JSON:
- dojo.fromJson(string) parses a JSON string to return a JavaScript object.
- dojo.toJson(Object) returns a JSON string given a JavaScript object.
