How to enable cross domain requests?

Question

JavaScript

Help with cross-domain requests.
There is a URL - eportal.com.ua/admin.php?start=1&count=10&brand=brand1
I make a GET request

$.ajax({
        type: "GET"
        url: @.url
        beforeSend: ->
          $('.content-spinner').show()
        complete: ->
          $('.content__spinner').hide()
        success: (data)=>
          @.needfullInfo = $.map(data, (item)->
            {
            id: item.ID
            name: item.NAME
            price: item.PRICE
            brand: item.BRAND
            desc: item.DESCRIPTION
            img_url: item.IMG
            img2: item.IMG2
            weight: item.WEIGHT
            volume: item.VOLUME
            }
          )
          @.attachTemplate()
          return
        error: =>
          $('.content__spinner').hide()
          errorPage = '../../errorPage.html'
          @.container.load(errorPage)
      })

gives an error message

XMLHttpRequest cannot load http://eportal.com.ua/admin.php?start=1&count=10&brand=brand1.
No 'Access-Control-Allow-Origin' header is present on the requested resource.
Origin 'http://192.168.0.100:3000' is therefore not allowed access.

I made a json file with the server response, put it in the project. Everything works fine with him, no errors.
Can something be done on the client side or is it just "there" that something needs to be changed?

Specify the permission for the domain or all connections on the server in the config.
