How to set price of service catalog item using a client script

[PranavSuj96]

Hello, 

I have a service catalog item which is used to rent cars. The customers can pick an available car through a reference variable that references my car inventory table. Each car record on the car inventory table has a price field. The price doesn't show or change. I tried to use an info message to display the price but the the message is blank. Any help would be appreciated!!

This is my current script:

function onChange(control, oldValue, newValue, isLoading) {
if (isLoading || newValue == '') {
return;
}
g_form.addInfoMessage(g_form.getValue('price'));
g_form.addInfoMessage('hello. script is running for dynamic price');
var car = g_form.getReference('cars',findPrice);

function findPrice(car) {
g_form.setValue('price',car.u_price_2);
}

insurance = g_form.getValue('u_insurance');
if (insurance == 'yes') {
g_form.setValue('price',g_form.getValue('price')+insurance);
}
}

i didn't work with getReference .. sorry about that..better you can use glide record and fetch the price for the particular car from the table ...just my suggestion

var carValue=g_form.getValue('car_variable_name');

var gr = new GlideRecord('your_table');
gr.addQuery('car', carValue);
gr.query(myCallbackFunction); //Execute the query with callback function

//After the server returns the query recordset, continue here
function myCallbackFunction(gr){
   while (gr.next()) { //While the recordset contains records, iterate through them
      console.log(gr.price);
   }
}

if you really wanted to use getReference ..refer this link
