问题

鉴于这个函数,我想用随机颜色生成器替换颜色.

 document.overlay = GPolyline.fromEncoded({
    color: "#0000FF",
    weight: 10,
    points: encoded_points,
    zoomFactor: 32,
    levels: encoded_levels,
    numLevels: 4
});
 

我该怎么做?

  最佳答案

使用getRandomColor()代替"#0000FF":

 function getRandomColor() {
  var letters = '0123456789ABCDEF';
  var color = '#';
  for (var i = 0; i < 6; i++) {
    color += letters[Math.floor(Math.random() * 16)];
  }
  return color;
}



function setRandomColor() {
  $("#colorpad").css("background-color", getRandomColor());
} 
 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="colorpad" style="width:300px;height:300px;background-color:#000">

</div>
<button onclick="setRandomColor()">Random Color</button>
