JavaScript : unable to merge two arrays

由 北战南征 提交于 2019-12-07 16:33:13
问题 I'm not a veteran of JavaScript and I have a little problem : In an AngularJS controller, I get 2 arrays from a WebService of the form [{"id":"1", "name":"aname1"}, {"id":"2", "name":"aname2"}] . They have both the same structure (this shouldn't be important). With concat() or push() I'm unable to merge these arrays together, and I don't understand why. I tried var arrayS = Service.list(); // Get data from WebService var arrayAE = ActeurExterne.list(); // Idem var arrayRes = arrayS.concat
