Examples
This example gets the JSON blob data.
blob lblb_Json
Long ll_RootObject
JsonGenerator lnv_JsonGenerator
lnv_JsonGenerator = Create JsonGenerator
// Create an object root item
ll_RootObject = lnv_JsonGenerator.CreateJsonObject()
// Add a value child item
lnv_JsonGenerator.AddItemString(ll_RootObject, "string", "string")
lnv_JsonGenerator.AddItemNumber(ll_RootObject, "long", 100)
lnv_JsonGenerator.AddItemDateTime(ll_RootObject, "datetime", datetime("2017-09-21 12:00:00"))
// Gets the JSON data
lblb_Json = lnv_JsonGenerator.GetJsonBlob()
This example packages the data of DataWindow, DataStore and DataWindowChild object and assigns the value to a blob.
blob lblb_json
datastore lds_employee
datawindowchild ldwc_active
JsonPackage lnv_package
lnv_package = create JsonPackage
...//Initialize data for lds_employee, ldwc_active
// package the data
lnv_package.SetValue("d_department", dw_department, false)
lnv_package.SetValue("d_employee", lds_employee)
lnv_package.SetValue("dddw_active", ldwc_active, false)
lblb_json = lnv_package.GetJsonBlob()See also
