OpenLayers 3: simple LineString example

问题:

i'm new to OpenLayers and i am looking for some help drawing lines on a map, i've been trying various things from various different posts about drawing LineStrings but i can't get it to work! I just need to figure out how to draw a line between to coordinates.

heres some code that i tried but didn't work:

var points = [
    new ol.geom.Point([78.65, -32.65]),
    new ol.geom.Point([-98.65, 12.65])
  ];

var featureLine = new ol.Feature({
    geometry: new ol.geom.LineString(points)
  });

var sourceLine = new ol.source.Vector({
    features: [featureLine]
  });

var vectorLine = new ol.layer.Vector({
    source: sourceLine
  });

map.addLayer(vectorLine);

i also tried this but to no avail:

var layerLine = new ol.layer.Vector({
      source: new ol.source.Vector({
          features: [new ol.Feature({
              geometry: new ol.geom.LineString(points, 'XY'),
              name: 'Line'
          })]
      }),
  });

map.addLayer(vectorLine);

can someone point me in the right direction? or tell me where i am going wrong?

EDIT: thanks to Jonatas, the working code looks like this:

  var coordinates = [[78.65, -32.65], [-98.65, 12.65]]; 

  var layerLines = new ol.layer.Vector({
      source: new ol.source.Vector({
          features: [new ol.Feature({
              geometry: new ol.geom.LineString(coordinates),
              name: 'Line'
          })]
      }),
  });

  map.addLayer(layerLines);

回答1:

Just change this:

var points = [
    new ol.geom.Point([78.65, -32.65]),
    new ol.geom.Point([-98.65, 12.65])
];

To:

var points = [
    [78.65, -32.65], [-98.65, 12.65]
];

The ol.geom.LineString constructor accept an array of coordinates.
