How to get list field values (multiple) of form in Client Script ?

[Ankita Misstry]

Hello ,

I am new to servicenow. I am trying to get all form data in client script on-load event. I have created custom table and  custom form. Now i have added list field where i can select multiple incident numbers. I want these numbers on-load client script. I have selected 3 incident numbers and i am getting 3 sys_id when i tried to getvalue.  What should I do ?

var inciNumbers = g_form.getValue('u_incident_number');
alert(inciNumbers);

It gives me 3 sys_ids. Not incident numbers.

Please check attached screen,

Please help. Thanks !

The value of a list field is a list of sysid's, so when you do getValue on that field you will get a result like this 

['d37aaa42d7330200a9addd173e24d460','d37aaa42d7330200a9addd173e24d460','d37aaa42d7330200a9addd173e24d460']

If you wish to get the incident numbers, get the references from these values, and then get the number.

This code is an example, and may not be 100% perfect, but it will be similar if it doesn't work.

var inclist = g_form.getValue('u_incident_number');
var numberlist = [];
var records = new GlideAjax("incident");
records.addQuery("sys_id","IN",inclist);
records.query();
while(records.next()){
  numberlist.push(records.getValue("number"));
}
alert(numberlist);

Try this with a combination of Display Business rule and OnLoad Client script

1. Configure a Display Business rule on your custom table.

(function executeRule(current, previous /*null when async*/) {

	var incNumbers = [];
incNumbers.push(current.u_incident_number.getDisplayValue().toString());


	g_scratchpad.incNumber = incNumbers;


})(current, previous);

2. OnLoad Client Script.

function onLoad() {
alert(g_scratchpad.incNumber);
}
