IE和FireFox中Table创建,事件绑定代码

//创建TR
			function createTr(){ 
				var nodeTr=document.createElement("tr");
				var nodeTd=document.createElement("td");
				var nodeText=createInput("filterkey","text","","ctext");
				nodeTd.appendChild(nodeText);
				nodeTr.appendChild(nodeTd);
				nodeTd=document.createElement("td");
				nodeText=createInput("filtervalue","text","","ctext");
				nodeTd.appendChild(nodeText);
				nodeTr.appendChild(nodeTd);
				nodeTd=document.createElement("td");
				nodeText=createInput("filterbutton","button","删除","cbutton");
				nodeTd.appendChild(nodeText);				
				nodeTr.appendChild(nodeTd);
				return nodeTr; 
			}		
			//创建Text/Button,js中不能使用保留关键字作为参数名称，例如name,value等
			function createInput(propertyName,propertyType,propertyVal ue,propertyClass){
			    var element = '';
			    try{
					element = document.createElement("<input type=""+propertyType+"" name=""+propertyName+"" value=""+propertyValue+"">");
				}catch(e){
					element = document.createElement("input");
					element.setAttribute("type",propertyType);
					element.setAttribute("name",propertyName);
					element.setAttribute("value",propertyValue);
				}
			    element.setAttribute("className",propertyClass);		
			    element.setAttribute("class",propertyClass);
 				if(propertyType=="button"){
					if (document.all)
						element.attachEvent("onclick",deleteFilterRule);
					else
						element.addEventListener("click",deleteFilterRule,false);
			    }	        
			   return element;
			}	
			//在指定元素之后添加
			function  appendAfter(nodeId){ 
				var node=document.getElementById(nodeId);
				var nn=createTr();
				if(node.parentNode){
					if(node.nextSibling){
						node.parentNode.insertBefore(nn,node.nextSibling);							
					}else{
						node.parentNode.appendChild(nn);
					}
				}		
			}	
			//删除元素	
			function deleteFilterRule(nodeId){
				var jsFirstTr=document.getElementById("firstTr");
				var nodeDelete=null;
				var nodeParent=jsFirstTr.parentNode;			
				if(nodeId=='allRule'){
