jQuery简单实现彩色云标签效果示例

本文实例讲述了jQuery简单实现彩色云标签效果的方法。分享给大家供大家参考，具体如下：

一、JS Code：

<script type="text/javascript">
$(function () {
  randomCloudLabel();
});
function randomCloudLabel() {
  var obj = $("#CloudLabel a");
  function rand(num) {
    return parseInt(Math.random() * num + 1);
  }
  function randomcolor() {
    var str = Math.ceil(Math.random() * 16777215).toString(16);
    if (str.length < 6) {
      str = "0" + str;
    }
    return str;
  }
  for (len = obj.length, i = len; i--; ) {
    obj[i].style.left = rand(600) + "px";
    obj[i].style.top = rand(400) + "px";
    obj[i].className = "color" + rand(5);
    obj[i].style.zIndex = rand(5);
    obj[i].style.fontSize = rand(50) + 12 + "px";
    obj[i].style.color = "#" + randomcolor();
  }
}
</script>

二、Html Code：

<div id="CloudLabel">
  <a href="#">web标准学习</a><a href="#">css</a> <a href="#">javascript</a><a href="#">html5</a>
  <a href="#">canvas</a><a href="#">video</a> <a href="#">audio</a><a href="#">jQuery</a>
