How can we use indexOf for system property?

[Sathwik1]

Type field is a list collector....so it consists more than one value....so in that I need to check whether the below sysid is there or not...so I have used indexof method.....it is perfectly working fine....but hardcoding sys id  is not a best practice....so I want to replace with system property... is it possible to do without glideajax?

var grType = g_form.getValue('type');
var k = grType .toString().indexOf("d6263df300176cd7da6t54bf2632c");

You could use the scratchpad to query the system property in a business rule and then access that scratchpad value in a client script. Display Business Rules

You could also use the Messages table to store the sys_id of the type. There is a Messages field on client scripts that allow you to pull in messages and make them available to the client script. Message Table

As suggested used display business rule...used scratch pad...

but what is the format I need to set inside index of?

Display BR

  g_scratchpad.type= gs.getProperty("system_property_name");

client script

var k = grType .toString().indexOf("");

what needs to be write under index of?
