baidu地图api使用

  var stra = '120.23026600569044:30.31146623753541,120.23026600569044:30.31146623753541';
var strarr = stra.split(',');
  var polylineTmp = new Array();
  for (var i = 0; i < strarr.length; i++) {
    var one = strarr[i].split(':');
      polylineTmp[i] = new BMap.Point(one[0], one[1]);
  }
