表格中删除指定行javascript操作

function $(objId){ return document.getElementById(objId); } function del_tbl(tblN,ckN){ var ck = document.getElementsByName(ckN);     var tab = $(tblN);    var existCk = false; var rowIndex;if(ck){ for(var i=0;i<ck.length;i++){         if(ck[i].checked){         existCk = true;rowIndex = ck[i].parentNode.parentNode.sectionRowIndex;         tab.deleteRow(rowIndex); i = -1; } } }if (!existCk) {alert('请选择要删除的记录');}}

生成表格的javascript：

 function initTable(params){        var tableData = "<table id=\"decoderResourceTable\"  class=\"list-table\" align = \"center\"   style=\"margin:0;padding:0;\" cellspacing=\"1\" cellpadding=\"0\">";        tableData = tableData + "<tr>";            tableData = tableData + "<td width=\"8%\" align=\"center\"><input type = \"checkbox\" id = \"checkAllId\" onclick = \"checkAll(this)\"/></td>";        tableData = tableData + "<td width=\"12%\" align=\"center\">编号</th>";        tableData = tableData + "<td width=\"34%\" align=\"center\">解码设备名称</td>";        tableData = tableData + "<td width=\"22%\" align=\"center\">设备类型</td>";        tableData = tableData + "<td width=\"24%\" align=\"center\">IP地址</td>";        tableData = tableData + "</tr>";                for(var i=0; i<params.length; i++){        if (params[i] != ""){        var rowParams = params[i].split(";");        if(rowParams.length == 4){            if( i%2 == 1 ){               tableData = tableData + "<tr class=\"trEven\" align=\"center\" id=\"" + nCol + "\" onClick=\"\";>";            } else {               tableData = tableData + "<tr class=\"trOdd\" align=\"center\" id=\"" + nCol + "\" onClick=\"\";>";              }        tableData = tableData + "<td class=\"list\"><input id = \"checkboxDecodesId\" type = \"checkbox\" name = \"checkboxRlDecodes\" /></td>";        tableData = tableData + "<td class=\"list\">" + nCol + "</td>";        tableData = tableData + "<td class=\"text-left\" class=\"list\">" + rowParams[1] + "</td>";        tableData = tableData + "<td class=\"text-left\" class=\"list\">" + rowParams[2] + "</td>";        tableData = tableData + "<td class=\"text-left\" class=\"list\">" + rowParams[3] + "</td>";        tableData = tableData + "<input type=\"hidden\" name=\"decodeResId\" value=\"" + rowParams[0] + "\"/>";        tableData = tableData + "<input type=\"hidden\" name=\"typeMtdsId\" value=\"" + rowParams[2] + "\"/>";        tableData = tableData + "</tr>";        nCol++;        }        }        }        tableData = tableData + "</table>";        old_Decoder = null;                return tableData;        }

全选所有checkBox的操作

function checkAll(chk){   var chkArray;   chkArray=document.getElementsByName("checkboxRlDecodes");   if(chk){   if(chkArray){   for(var i=0;i<chkArray.length;i++){   chkArray[i].checked=chk.checked;   }   }   }}
