You can't use a variable as identifier in an object literal. You just can add another dynamic property after object creation:

var s = document.getElementById("myvalue").textContent;

var obj = {
  url: "http://localhost:53698/mobile_ODataService.svc/",
  jsonp: true,
  errorHandler: function (error) {
     alert(error.message);
  },
  entities : {}
};
obj.entities[s] = { key: "id" };

You have to do this after the object creation.

var s = document.getElementById("myvalue").textContent;

var obj = {
    url: "http://localhost:53698/mobile_ODataService.svc/",
    jsonp: true,
    errorHandler: function (error) {
        alert(error.message);
    }
};
obj[s] = {
    nom_articole: { key: "id" },
};
