吐槽垃圾IE
看下面的html：同志们请注意，IE下获取不到name为abc的input元素
<!DOCTYPE html><html><head><meta http-equiv="Content-Type" content="text/html; charset=gbk" /><title></title><script type="text/javascript">function test(e){ alert(document.getElementById('txt12').name);}</script></head><body onload="test()"><form><input name="txt12" type="text" style="width:95%;height:100%;font-family: 宋体;font-size:9pt;color:Gray;" runat="server" value="自动编号" readonly="readonly"/><input id="txt12" name='abc' type="text" style="width:95%;height:100%;font-family: 宋体;font-size:9pt;color:Gray;" runat="server" value="自动编号" readonly="readonly"/></form></body></html>
