Hi Bryce, indeed this is possible. pulling up one or two tricks .
Couple of things that you will need to know of how we can do this:
a) you will need to know the id by which your checkboxes are been named by ServiceNow. Or how to reach to these through the item_option_new table.
b) you will need to have an onLoad script on which you're going to define the onClick event for your checkboxes
Here goes a very simple example using OOB Fuji elements. We're going to make an alert that will display whenever the knowledge checkbox is checked or unchecked on the incident form. Keep in mind this is just an example. You can apply the exact same concept using a catalog client script on your catalog.
For this example you just need to create an onLoad client script the one is going to have a code like the following:
function onLoad() {
gel('ni.incident.knowledge').onclick = function() {
alert('This is checked: ' + this.checked + ' and its value is ' + this.value);
};
}
Notice that here we're defining what the onclick of the ni.incident.knowledge checkbox should be. You can use the exact same concept on an onLoad catalog client script where you iterate through your list of checkboxes defining the onclick function for each.
The script on an onLoad catalog client script will look something like this:
function onLoad() {
var sys_id_of_variable = 'dba29ae84fc20200fbb73fb28110c721';
gel('ni.IO:' + sys_id_of_variable).onclick = function() {
alert('This is checked: ' + this.checked + ' and its value is ' + this.value);
};
}
Notice that each variable has an id. You can identify and iterate through your checkbox variables by doing a GlideRecord query against the item_option_new table so that you can grab the sys_id of each variable associated to your catalog item and append the 'ni.IO:' at the start of it.
I hope this is helpful!
Thanks,
Berny
