我遇到個BUG 在IE上onclik事件觸發(fā)不了,谷歌和火狐都沒問題 IE10，11也沒問題 IE9以下都不行,
代碼如下：
html：

<th style="width:10%" >
                        <%=rp.getString("zdgl.zdgl.dlsj")%><%--登錄時間 --%>
                        <span id="timeUp" onclick="timeOrder(this);"  style="float:right; cursor:pointer">↑</span>
                        <span id="timeDown" onclick="timeOrder(this);" style="float:right;cursor:pointer">↓</span>
                
                    </th>
                    <th style="width:9%">
                        <%=rp.getString("zdgl.zdgl.lxts")%><%--離線天數(shù) --%>
                        <span id="dayUp" onclick="dayOrder(this);"  style="float:right; cursor:pointer">↑</span>
                        <span id="dayDown" onclick="dayOrder(this);" style="float:right;cursor:pointer">↓</span>
                    </th>

js：

    function timeOrder(obj){
    if(obj!=null&&obj!="undefined"&&obj.id=="timeDown"){
