鼠标移动上去变换背景色

 

1.用样式名
注意:是this.className  而不是this.style.className

<div class="subnavi-bottom">
                    <ul>
                        <li onmouseover="this.className='white12b current'" onmouseout="this.className='black12b'" class="black12b">&gt; 公司简介</li>

                        <li onmouseover="this.className='white12b current'" onmouseout="this.className='black12b'"><a href="#">&gt; 企业荣誉</a></li>
                        <li onmouseover="this.className='white12b current'" onmouseout="this.className='black12b'"><a href="#">&gt; 组织架构</a></li>
                    </ul>
                </div>

 2.直接用样式

 StringBuilder sb = new StringBuilder();
            string str_Sql = "select * from ProductClass where len(ClassRelation)=3";
            DataTable DT = PubAccessHelperFunc.GetDataTable(str_Sql);
            if (DT.Rows.Count > 0)
            {
                for (int i = 0; i < DT.Rows.Count; i++)
                {
                    sb.AppendLine("<tr onmouseover=\"this.bgColor='#7AB51E';document.getElementById('img" + i + "').src='images/icon.gif';\" onmouseout=\"this.bgColor='';document.getElementById('img" + i + "').src='images/icon1.gif';\">");
                    sb.AppendLine("<td align=\"center\" ><img src=\"images/icon1.gif\" width=\"4\" height=\"9\" id=\"img"+i+"\" /></td>");
                    sb.AppendLine("<td><a class=\"t\" href=\"Food.aspx?CR="+DT.Rows[i]["ClassRelation"].ToString()+"\">"+DT.Rows[i]["ClassName"].ToString()+"</a>");
                    sb.AppendLine("</td>");
                    sb.AppendLine("</tr>");                 
                }
            }
            else
            {
                ltl_Class.Text = "<center style=\"color:red;\">暂无!</center>";
            }
