关于动态新增表格的js

<script type="text/javascript">
		function addtabfun(){
			var tr = $("#itb tr").eq(1).clone();
			var last=$("#itb tr").last().attr("index");
			if(last==null){
			   last="0";
			}
			var tabsize=parseInt(last) + 1;
			$(tr).attr("index",tabsize);
			
			var lasttr=$("#itb tr").last()
			var name=$("select",lasttr).attr("name");
			var startindex=name.indexOf("[")+1;
			var endindex=name.indexOf("]");
			name=name.substring(0,startindex)+(parseInt(name.substring(startindex,endindex))+1)+name.substring(endindex,name.length);
			$("select",tr).attr("name",name);
			
			tr.find("td").get(1).innerHTML = "<input type=\"text\" name=\"punishGist\" class=\"punishGist\"/>";
			tr.find("td").get(2).innerHTML = "扣<input type=\"text\" name=\"score\" class=\"score\"/>分";
	        tr.show();
	        tr.appendTo("#itb");
		}
	</script>

页面中itb表格

页面中根据下拉列表获取数据内容并填充到对应字段js

 <script language="JavaScript">
            function badstandchange(that){
           		if($(that).val() != ""){
					 $.ajax({
					   type:'post',
					   data:'badStandardId='+$(that).val(),
					   dataType:'json',
					   url:'<%=request.getContextPath()%>/credit/deductionPointAction!queryViewData.action',
					   success:function(info){
						   setitemvalue(that,info);
						}
					 });
				}
            }
			
	        function setitemvalue(sel,val){
				var p=$(sel).parent().parent();
				$("input.score",p).val(val.score);
				$("input.punishGist",p).val(val.punishGist);
			}
			$(document).ready(function() {
				$("select.reloaddata").each(function(index,obj){
					 badstandchange(obj);
				});
				$("select.badStandard").live('change',function(){
					badstandchange(this);
					
				});
			});
</script>
