随机颜色发生器
2022-08-29 23:02:03
给定此功能,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?

用于代替 :getRandomColor()
"#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>
我怀疑任何事情都会比这个更快或更短:
"#" + ((1<<24)*Math.random() | 0).toString(16)
挑战!
