Description
Removes a key. If more than one key with the same name exists, then remove the first key. Notice that the IgnoreCase property (true by default) determines whether the key name will be matched in a case-sensitive manner.
Applies to
Syntax
objectname.remove ( Key )
Return value
Integer. Returns 1 if it succeeds and -1 if an error occurs. If any argument's value is null, the method returns null.
Examples
This example removes the "d_employess" key:
boolean lb_exist
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)
…
lnv_package.Remove("d_employee")
// lb_exist will return false
lb_exist = lnv_package.ContainsKey("d_employee")
