使用obj.appendChild(newRow);在页面中添加一行代码（<tr><td><input id="sId">..</td>.....</tr>），此行代码中包括一个onclick事件，参数包括document.getElementById（"sId"）。现象是代码添加成功，点击执行onclick事件时，找不到sId这个对象，document.getElementById（"sId"）=null。查看源码，添加的此行代码的没有问题。费解ing

方法一动态创建，方法二getElementById，我试了试，貌似我这边没有错，以前我也遇到过跟你一样的问题纳闷ing
[div#divvv1]然后就可以在上面加东西了:$('#divvv1').click(function(){
//blah blah
});
