Question

Test help ajax call web service to assign return value into Textbox

Answer 1

Hi @Shri Shankran ,

Per my understanding, "http://services.myportal.com/employee/advisees" should be an external domain custom web service which is outside SharePoint Online.

Then it's necessary to add Access-Control-Allow-Origin header in your custom web service, for example here is a demo to add custom header in .NET Web API Web.Conig:

Here is a similiar question for your reference:

Hi @ShridharHegde-2034,

The total count of array data can be got from the data in function(data), you can try to log it to browser Developer Tool using console.log(data) so that it's available to
check the detailed struct for data object.

It should be data.d.results.length similar as SharePoint Rest API. (maybe no d/results in data object as it's a custom web service)

In additional, I found your account is different with the account which post the original question, you can switch to the original account rather than use another account to response ther reply.
