导入高德地图并在页面中画了一条线，现在要用定时器改变线条的颜色，自己写的没有达到效果，完整页面代码如下：
<!doctype html>
<html>
<head>
<meta charset="utf-8">

<body>
<div id="container"></div>
<script>
var editorTool, map = new AMap.Map("container", {
resizeEnable: true,
center: [116.40, 39.90],//地图中心点
zoom: 13 //地图显示的缩放级别
});
//在地图上绘制折线
var editor={};
editor._line=(function( ){
var lineArr = [
[116.37, 39.91],
[116.38, 39.90],
[116.39, 39.91],
[116.39, 39.90]
];
return new AMap.Polyline({
map: map,
path: lineArr,
strokeColor: "#FF33FF",//线颜色
strokeOpacity: 1,//线透明度
strokeWeight: 3,//线宽
strokeStyle: "solid"//线样式
});
})();
map.setFitView();
debugger
var colorindex=0;
setTimeout("showColor()", 10000);
function showColor() {//改变颜色的方法
var colorarray=new Array('#FF33FF','#FF8C00','#EE00EE','#C0FF3E','#98FB98','#8B2500');
debugger
colorindex++;
debugger
this.editor._line.F.strokeColor=colorarray[colorindex];
map.setFitView();
setTimeout("showColor()", 10000);
}
</script>
</body>
</html>
下民这部分代码需要重新获取到dom对象
this.editor._line.F.strokeColor=colorarray[colorindex];
map.setFitView();
