How to restrict number of records on Glide List(list collector) of service catalog.

Sharique Azim · ‎08-04-2017

Hi All,

I am trying to restrict the number of records which can be selected in a glide list to be 5.

I can best figure out that if i can operate something similar to an array concept i can restrict the selection and alert.

My interest is particularly in glide list, as I dont want to show all the user's name at start.

Piece of my code is

 var maxOptions = 5;
   var selectedIDs = [];
   var str= selectedIDs.push(g_form.getValue('users'));
   alert(str);
   alert(str.length); //i know it would store a single string with multiple commas using this code
               var index = 0;
               for(var i = maxOptions; i < str.length; i++){
                       selectedIDs[index] = i;
                       index++;
             }

Kindly advice me on my code or any better approach..

This may work better as an onSubmit rather than an onChange. That way users can remove those list choices they deem unnecessary rather than relying upon the script to remove all but the first 5 entries. I am using list_variable as the variable name in my example:

function onSubmit() {

       g_form.hideFieldMsg('list_variable', true);

       var chkString = g_form.getValue('list_variable');

       var chkArray = chkString.split(','); 

       if (chkArray.length > 5) { 

               var eMessage = 'You cannot select more than 5 entries at a time';

               g_form.showFieldMsg('list_variable', eMessage, 'error');

               return false;

       }

}

Let me know if this is more successful since I have not tested it.

There are several built in functions that let you configure your GlideList. Take a look at the setRowsPerPage() function:

Hi Christopher,

I am building a onChange script to perform the job as this is a catalog item..

Can the solution provided by you work in client side?

I have used g_list as a way of setting a filter on the list in the portal using a client script. Was thinking that the information contained would be helpful. Here is an example I found for catalog:

Thanks..I am not setting the filter but restricting the number of selections
