How to check validate to select 2 checkboxes in 6 checkboxes in service now

[sree42]

Hi Team,

I have one requirement to select only 2checkboxes from 6 checkboxes in an order guide. I mean to restrict only 2checkboxes from 6 checkboxes in options as below using on submit client script?

If we select more than 2 checkboxes from the options, then it should display error message when submit. only 2 checkboxes from this should select. if more than that error msg should display. Please help anyone.

Hello @sree42 

You need to write onSubmit() Client Script :-

function onSubmit(){

var chk1 = g_form.getControl('checkbox_1');
var chk2 = g_form.getControl('checkbox_2');
var chk3 = g_form.getControl('checkbox_3');
var chk4 = g_form.getControl('checkbox_4');
var chk5 = g_form.getControl('checkbox_5');
var chk6 = g_form.getControl('checkbox_6');

var arrchk = [chk1,chk2,chk3,chk4,chk5,chk6];

var count=0;

for(let i=0; i<arrchk.length; i++){
if(arrchk[i].getChecked){
count++;
}
}

if(count>2){
return false;
gs.info('your error msg')
}

}

Hi Samaksh,

Thanks for this code. This is not working as expected. But it is working in another way. Thank you!

function onSubmit(){

var chk1 = g_form.getValue('checkbox_1');
var chk2 = g_form.getValue('checkbox_2');
var chk3 = g_form.getValue('checkbox_3');
var chk4 = g_form.getValue('checkbox_4');
var chk5 = g_form.getValue('checkbox_5');
var chk6 = g_form.getValue('checkbox_6');

var arrchk = [chk1,chk2,chk3,chk4,chk5,chk6];

var count=0;

for(var i=0; i<arrchk.length; i++){
if (arrchk[i] == 'true') {
            count++;
        }
}

if(count>2){
g_form..addErrorMessage('error');
return false;

}

}
