How to restrict users to select not less 2 records in list collector in serviceNow

[Sowmya]

The purpose of list collector is to select more than 1 records . Can we populate an alert message to select more than 1 record in list collector ServiceNow. Kindly let us know the update asap.

HI @Sowmya ,
I trust you are doing great.
You can do it using the client script on change one.

Once the value is changed into the list collector it will be passed to the backend where it will be shown as comma seperated sysIds for the reference.

var glideList = g_form.getValue('<glide list field>');

It will give output as sys_id1,sys_id2.
Then you can split it as given below :
var glideListArray = glideList.split(',');

if (glideListArray.length > 2) {

alert ('Invalid')

}

Hi Amit,

Thanks for the solution,

I tried the onchange client script which you suggested. But not working Basically it should throw an alert message if i select only one record in list collector.

function onChange(control, oldValue, newValue, isLoading) {
var glideList = g_form.getValue('user_list');

var glideListArray = glideList.split(',');

if (glideListArray.length > 2) {

alert ('Invalid');

}
}
