如何使用雅虎颜色选择器更改背景颜色

Question

大家好，我有一项任务，需要将 Yahoo UI 颜色选择器集成到网站中。当有人选择一种颜色时，页面的背景需要变成该颜色。

我按照此处的说明 http://developer.yahoo.com/yui/colorpicker/#events 但我似乎不知道如何将背景颜色更改为所选颜色。当有人选择颜色时，我可以更改背景，但是我不知道如何获取选择为输入/的颜色（请参阅 // 注释的代码），直到现在我有这个：

在 head:

<!-- Dependencies --> 
<script src="http://yui.yahooapis.com/2.8.2r1/build/utilities/utilities.js" ></script>
<script src="http://yui.yahooapis.com/2.8.2r1/build/slider/slider-min.js" ></script>

  <!-- Color Picker source files for CSS and JavaScript -->
<link rel="stylesheet" type="text/css" href="http://yui.yahooapis.com/2.8.2r1/build/colorpicker/assets/skins/sam/colorpicker.css">
<script src="http://yui.yahooapis.com/2.8.2r1/build/colorpicker/colorpicker-min.js" ></script>

then 在 body 标记中： class="yui-skin-sam"

并在正文中：

<div id="container"></div>
<script type="text/javascript">
var picker = new YAHOO.widget.ColorPicker("container", {
 showhsvcontrols: true,
 showhexcontrols: true,
 images: {
  PICKER_THUMB: "picker_thumb.png",
  HUE_THUMB: "hue_thumb.png"
 }
});

//a listener for logging RGB color changes;
//this will only be visible if logger is enabled:
var onRgbChange = function(o) {
 /*o is an object
  { newValue: (array of R, G, B values),
    prevValue: (array of R, G, B values),
    type: "rgbChange"
   }
 */
    // with this code i change the background when a color is picked, but not with the input col.
    // document.body.style.backgroundColor = 'green';
 YAHOO.log("The new color value is " + o.newValue, "info", "example");
}

//subscribe to the rgbChange event;
picker.on("rgbChange", onRgbChange);

  </script>

Answer 1

将背景颜色设置为 RGB 值（o.newValue 给出的值）的语法如下所示：

doc.style.backgroundColor="rgb(239,239,239)";

...所以，尝试这样的操作：

document.body.style.backgroundColor = "rgb(" + o.newValue[0] + "," + o.newValue[1] + "," + o.newValue[2] + ");"
