GlideDialog Window Example

In ServiceNow, you can make great AJAX dialog windows (GlideDialogWindow). They use an UI Page that can insert, update, or delete records, prompt for interaction, or just about anything allowed in Javascript.

From the ServiceNow Wiki, here is some documentation to read before you start building your GlideDialogWindow.

Here is an example that will allow you to create a new caller when in the Incident Form:

UI Action: New Caller

Table: Incident
Form Context Menu: true
Active: true
Show Update: true
Client: true
OnClick: newCaller()
Condition: !current.isNewRecord()
Script:
function newCaller() {
 var sysId = typeof rowSysId == 'undefined' ? gel('sys_uniqueValue').value : rowSysId;
 var gDialog = new GlideDialogWindow("inc_new_caller");
 gDialog.setTitle("New Caller");
 gDialog.setPreference('sysparm_sysID', sysId);
 gDialog.setPreference('sysparm_table', "incident");
 gDialog.render();
}

Hope that gives you some ideas when you are making your own dialog windows.
