[OpenLayers-Users] Adding multiple WMS layers in OpenLayers

[Zach Seaman]

OL is initialized. I'm adding them via .addLayer([agregadas]). It's very
odd to me why it would work in the console but not on the page load.

This function creates the layers:

function crear( n ){
            $.getJSON('json/capas.json', function(data) {
                console.log(data);
              for (var i=0; i < n.length; i++) {
                        capaObjetos[i] = new OpenLayers.Layer.WMS(
                                      data[0][i]["id"],
                                      data[0][i]["url"],
                                      {
                                      "layers": data[0][i]["layers"],
                                        transparent: true,
                                        format:"image/png",
                                        CQL_FILTER: queryCQL(i),
                                        projection: map.projection,
                                        displayOutsideMaxExtent: false
                                      },
                                      {
                                        singleTile: true,
                                        ratio: 1,
                                        buffer: 0,
                                        visibility: false
                                      }
                                  );
                      // console.log(capaObjetos[i]);


              }

                for (var key in capaObjetos) {
                      var value = capaObjetos[key];
                      agregadas.push(value);
                }

            });

    }

agregadas = [ ];

// Variables de Capas para capaObjectos
    var crasicaule, microfilo, rosetofilo, submontano, perennifolia,
caducifolia, encino, pino, mezquite, tascate, mesofilo, oyamel, inducidos,
halofilo,
    natural, cultivados, gipsofilo, riego, temporal, mezquital, tular,
sinvegetacion, asentamientos, carretera;

    var capaObjetos = {
              "0": crasicaule,
              "1": microfilo,
              "2": rosetofilo,
              "3": submontano,
              "4": perennifolia,
              "5": caducifolia,
              "6": encino,
              "7": pino,
              "8": mezquite,
              "9": tascate,
              "10": mesofilo,
              "11": oyamel,
              "12": inducidos,
              "13": halofilo,
              "14": natural,
              "15": cultivados,
              "16": gipsofilo,
              "17": riego,
              "18": temporal,
              "19": mezquital,
              "20": tular,
              "21": sinvegetacion,
              "22": asentamientos,
              "23": carretera
    };

$(document).ready(function () {
                capaBase();
                TreeMenu();

    // ======= AGREGAR CAPAS DE 'USO DEL SUELO' AL MAPA ===========

               map.addLayers(agregadas);

});


Thanks
