How to limit the list collector choices selection

Sai Akhil · ‎10-05-2020

Hi All,

I have a requirement where I am using a variable as a list collector in a catalog item, where users can select up to 3 choices if they exceed the limit then they should populate the message that the limit is exceeded. please let me know how to achieve this.

Thanks in advance,

Akhil.

Hi,

write onSubmit catalog client script

Applies to Catalog Item

Applies on Catalog Item view - True

UI Type = ALL

Note: give your list collector variable name below

function onSubmit()

var values = g_form.getValue('variableName').toString().split(',');

if(values.length > 3){

alert('Please select only 3 choices');

return false;

}

}

Hi @Narra Ramakotes ,

Below the code for Removing the last record .

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

   //Type appropriate comment here, and begin script below

var values = g_form.getValue('who_are_need_to_access').split(',');
    //g_form.addInfoMessage('total value in users '  + values);

if(values.length > 5){
g_form.clearMessage();
values.pop() // remove the last record
 g_form.setValue("DL_Members", Members.join());
g_form.addErrorMessage('Please select only 5 choices');
}
   
}
