标签云中的标签随机排列 

 1 <script type="text/javascript">
 2     var tagList = new Array("HTML","XHTML","CSS","JavaScript","JSON","RIA","jQuery");
 3     
 4     function randomTag(array) {
 5         var x = new Array();
 6         var y;
 7         var j = 0;
 8         
 9         for(var i=array.length; i>=1; i--) {
10             y = Math.floor(Math.random() * array.length);
11             x[j] = array[y];
12             array.splice(y,1);
13             j++;
14         }
15         return x;
16     }
17     
18     function outputHtml() {
19         var html = "<div>";
20         var x = randomTag(tagList);
21         for(var i = 0; i < x.length - 1; i++) {
22             html += x[i] + ",";
23         }
24         html += x[i] + "</div>";
25         
26         return html;
27     }
28     
29     document.write(outputHtml());
30  </script>

 

每次刷新后标签重新排列显示；

version_0.1 去除了显示在最后的标点;
