代码如下，如果是class则取出的颜色值是空，但如果直接用style则正确，不知怎么解决<html><head><style type="text/css">p.ci_1 {color: #80FF80;}</style><script type="text/javascript">function setColor(){var g_all = document.getElementsByTagName("p");var n = g_all.length;for (var i = 0; i < n; i++){// g_all[i].style.color="#80FF80";alert("aa--"+g_all[i].style.color+"--bb");}}</script></head><body><p class='ci_1'>This is an example paragraph.</p><p style='color: #80FF80' >This is also an example paragraph.</p><input type="button" onclick="setColor()" value="Change color of text" /></body></html>

点击“获得背景色”按钮，会调用getHexBgColor()方法获取css的背景色。
