Not sure the requirements but the following code will add work notes to an incident. Note, the onChange variable is the variable with the incident number. The script will add a work note to the incident with the entered incident number.
May be, it would be better to create a business rule instead of a client script?
Client script
function onChange(control, oldValue, newValue, isLoading) {
if (isLoading || newValue == '') {
return;
}
var ajax = new GlideAjax('GetAttachmentFilename');
ajax.addParam('sysparm_name', 'getFilename');
ajax.addParam('sysparm_number', newValue);
alert(newValue);
ajax.getXMLAnswer(function(answer) {
if (answer.length > 0) {
alert(answer);
}
});
}
Script include:
var GetAttachmentFilename = Class.create();
GetAttachmentFilename.prototype = Object.extendsObject(AbstractAjaxProcessor, {
getFilename: function() {
var filenames = [];
var number = this.getParameter('sysparm_number');
var grInc = new GlideRecord('incident');
if (grInc.get('number', number)) {
var grAtt = new GlideRecord('sys_attachment');
grAtt.addQuery('table_sys_id', grInc.sys_id);
grAtt.query();
while (grAtt.next()) {
filenames.push(grAtt.file_name.toString());
grInc.work_notes = grAtt.file_name.toString();
}
grInc.update();
}
return JSON.stringify(filenames);
},
type: 'GetAttachmentFilename'
});Sample of incident with work notes entered via script.
