javascript在IE中不能运行，FF中能运行。

我现在想点一个“+”号，表格动态的添加一行，写出来了，在ie中没反应也不报错。在FF中一切正常。
大家帮我看看问题出在哪里啊 。。
       
        var ta1 = document.createElement("textarea");
        var ta2 = document.createElement("textarea");
        var ta3 = document.createElement("textarea");
        var ta4 = document.createElement("textarea");
        
        ta1.setAttribute("id","title");
        ta1.setAttribute("name","title");
        ta1.setAttribute("cols","35");
        ta2.setAttribute("id","content");
        ta2.setAttribute("name","content");
        ta2.setAttribute("cols","80");
        ta3.setAttribute("id","ration");
        ta3.setAttribute("name","ration");
        ta4.setAttribute("id","planDay");
        ta4.setAttribute("name","planDay");
        ta4.setAttribute("readonly","readonly");
        ta4.setAttribute("onfocus","WdatePicker({startDate:'%y-%M-01 00:00:00',dateFmt:'yyyyMMdd',alwaysUseStartDate:true})");   
        
        var td1 = document.createElement("td");
        var td2 = document.createElement("td");
        var td3 = document.createElement("td");
        var td4 = document.createElement("td");
        
        td1.setAttribute("align","center");
        td1.setAttribute("colspan","2");
        td2.setAttribute("align","center");
        td2.setAttribute("colspan","4");
        td3.setAttribute("align","center");
        td4.setAttribute("align","center");
        
        var rt = document.createElement("tr");
        rt.setAttribute("id","tr");
        
        td1.appendChild(ta1);
        td2.appendChild(ta2);
        td3.appendChild(ta3);
        td4.appendChild(ta4);
        
        rt.appendChild(td1);
        rt.appendChild(td2);
        rt.appendChild(td3);
        rt.appendChild(td4);
        
        var tb = document.getElementById("addTable");
        tb.appendChild(rt);表格的原样：<table border="1" id="addTable" name="addTable">
<tr>
<td align="center" colspan="2"><textarea id="title" name="title" cols="35"></textarea></td>
<td align="center" colspan="4"><textarea id="content" name="content" cols="80"></textarea></td>
<td align="center"><textarea id="ration" name="ration"></textarea></td>
<td align="center"><textarea id="planDay" name="planDay" readonly="readonly" onfocus=
"WdatePicker({startDate:'%y-%M-01 00:00:00',dateFmt:'yyyyMMdd',alwaysUseStartDate:true})"></textarea></td>
</tr>
</table>

  1.   

    是否能把整个页面的源码都贴出来？
    JS在IE中和FF中运行效果不一样的问题太常见了。确实挺讨厌的。
      

  2.   

    有的IE把执行脚步文件这个选项关了，你可以在IE的选项里看看

  4.   

    这次全贴出来了，我想实现点+号就增加一行，-就删除一行，但是至少要保留一行。
    就上面得这段代码在ie中不行，在FF中就行。
      

  5.   

    IE 现在不是自带JS调试的吗  你看看具体哪行报错
