<body>
<table id="count">
<tr><th>序号</th><th>姓名</th><th>金额[USD]</th><th>时间</th><th>项目</th><th>单位</th><th>备注</th></tr>
<tr>
<td>1</td>
<td><input type="text" /></td>
<td><input type="text" /></td>
<td><input type="text" /></td>
<td><input type="text" /></td>
<td><input type="text" /></td>
<td><input type="text" /></td>
</tr>
</table>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js" type="text/javascript"></script>
<script type="text/javascript">
$(function(){
/* 这是一种方法，但是不精简，不过很好理解，就像面向过程编写代码一样。
var oTable = $("#count"), oTr = '', oInput = '', eEle = '';
oTable.on('mouseover', function(){
oTr = oTable.find('tr').last();
oInput = oTr.find('input');
eEle = oTr.clone();
oInput.on('click', function(){
var parent = $(this).parents('tr');
if(oTr.index() == parent.index()){
oTable.append(eEle);
}
});
});
*/
//这是第二种方法，比较精简，要看对jQ的理解了。
var oTable = $("#count"), iNum = 1, eEle = '';
oTable.on('click', function(e){
var target = e.target,
oTr = $(target).closest('tr');
if(oTr.index() == oTable.find('tr').last().index()){
iNum++;
eEle = oTr.clone();
eEle.find('td').eq(0).text(iNum);
}
oTable.append(eEle);
});
});
</script>
</body>
</html>运行看效果吧
