如何将随机数值放入 svg“fill”属性的“rgb()”中？

Question

我的网站上有一个svg元素，我想对其进行动画处理，以便它从随机颜色值更改为另一个随机颜色值。我现在拥有的看起来像这样：

<?xml version="1.0" standalone="no"?>

<svg width="8cm" height="3cm" viewBox="0 0 800 300" xmlns="http://www.w3.org/2000/svg">

  <desc>Example anim01 - demonstrate animation elements</desc>

  <rect x="1" y="1" width="900" height="400"

        fill="none" stroke="none" stroke-width="2" />

  <!-- The following illustrates the use of the 'animate' element

        to animate a rectangles x, y, and width attributes so that

        the rectangle grows to ultimately fill the viewport. -->

  <rect id="RectElement" x="300" y="100" width="300" height="100"

        fill="rgb(0,255,0)"  >

    <animate attributeName="fill" begin="0" dur="1.3"

    fill="remove" from="rgb(0,255,0)" to="rgb(255,0,0)" repeatCount="indefinite"/>

    <animate attributeName="x" begin="0s" dur="1.3s"

             fill="freeze" from="300" to="0" repeatCount="indefinite"/>

    <animate attributeName="y" begin="0s" dur="1.3s"

             fill="freeze" from="100" to="0" repeatCount="indefinite"/>

    <animate attributeName="width" begin="0s" dur="1.3s"

             fill="freeze" from="300" to="800" repeatCount="indefinite"/>

    <animate attributeName="height" begin="0s" dur="1.3s"

             fill="freeze" from="100" to="300" repeatCount="indefinite"/>

    

    

  </rect>

  <!-- Set up a new user coordinate system so that

        the text string's origin is at (0,0), allowing

        rotation and scale relative to the new origin -->

  <g transform="translate(100,100)" >

    <!-- The following illustrates the use of the 'set', 'animateMotion',

         'animate' and 'animateTransform' elements. The 'text' element

         below starts off hidden (i.e., invisible). At 3 seconds, it:

           * becomes visible

           * continuously moves diagonally across the viewport

           * changes color from blue to dark red

           * rotates from -30 to zero degrees

           * scales by a factor of three. -->

但我想要的是为矩形分配一个随机颜色值（类似于“rgb（随机＃，随机＃，随机＃）”）。

我该如何做才能确保每种颜色都是可能的结果？

let refreshRate = 1300;function rand(max){&nbsp; return Math.floor(Math.random() * (max+1));};setInterval(function(){document.getElementById("RectElement").setAttribute("fill","rgb("+rand(255)+", "+rand(255)+", "+rand(255)+")");},refreshRate);
