Client script for Incident State transition

[prabhmeet]

Hi,

I am new to Servicenow. I have to perform the following task -

Design the below state transition for incident. Create the state if not available.

1. When an incident ticket is in "New" state, next states shown are: Active, Canceled
2. When an incident ticket is in "Active" state, next states shown are: Awaiting User Info, Awaiting Problem, Awaiting Evidence, Awaiting Vendor, Resolved and Canceled
3. When an incident ticket is in "Awaiting User Info" state, next states shown are: Active, Canceled
4. When an incident ticket is in "Awaiting Problem" state, next states shown are: Active, Canceled
5. When an incident ticket is in "Awaiting Vendor" state, next states shown are: Active, Canceled
6. When an incident ticket is in "Resolved" state, next state shown is: Active

When an incident ticket is in "Resolved" state, system automatically closes the ticket after 3 days.

I have created the States which were not present using Choice List. I know this can be done using State Models and state transitions (I have done it using State model module) but I need to do this using Client Script.

The script I have written - 

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
if (isLoading || newValue === '') {
return;
}

//Type appropriate comment here, and begin script below

var _state = g_form.getValue('state');

if(_state == '1'){
g_form.clearOptions('state');
g_form.addOption('state','-10','Active');
g_form.addOption('state','8','Cancelled');
}
if(_state == '-10'){
g_form.clearOptions('state');
g_form.addOption('state','-11','Awaiting User Info');
g_form.addOption('state','-12','Awaiting problem');
g_form.addOption('state','-13','Awaiting Evidence');
g_form.addOption('state','-14','Awaiting Vendor');
g_form.addOption('state','8','Cancelled');
g_form.addOption('state','6','Resolved');
}

if(_state == '-11'){
g_form.clearOptions('state');
g_form.addOption('state','-10','Active');
g_form.addOption('state','8','Cancelled');
}

if(_state == '-12'){
g_form.clearOptions('state');
g_form.addOption('state','-10','Active');
g_form.addOption('state','8','Cancelled');
}

if(_state == '-14'){
g_form.clearOptions('state');
g_form.addOption('state','-10','Active');
g_form.addOption('state','8','Cancelled');
}

if(_state == '6'){
g_form.clearOptions('state');
g_form.addOption('state','-10','Active');
}

else{
g_form.clearOptions('state');
}
}

This is not working. Can someone please help with the script?

Check every current state using g_form.getValue() and using addOption and removeOption of g_form have these states as the dropdown choices at respective states 

That should work if not with state flows 

Thanks,

Siva

Could you write it for one of the conditions, just so I can understand and write properly?

Here a sample of code to be used:

if(g_form.getValue('state') == '40'){

   g_form.removeOption('state', '10');
   g_form.addOption('state', '50', 'Execution');
}

Please, remember to mark Correct or Helpful if you find my response useful.

Cheers
Alberto
