1.首先在span標簽或者div標簽上面添加class=”shanshuo”

2.編寫js代碼

<script>

$(function () {

setInterval(‘set_Word_shanshuo ()’, 3000);

})

Function set_word_shanshuo () {

Var color = [‘red’, ‘green’, ‘yellow’, ‘black’, ‘purple’];

$(‘.shanshou’).CSS(‘color’,color[parseInt( Math.random()*color.length)]);

}

</script>

或者：

<script language="javascript">

function changeColor(){

var color="#ff0000|#00ff00|#0000ff|#888800|#880088|#008888|yellow|green|blue|gray";

color=color.split("|");

  $('.blink').css('color', color[parseInt(Math.random() * color.length)]);

}

$(function () {

  setInterval("changeColor()",200);

})</script>
