动态增删表格中的行【代码片段】

//----------------为表格添加一个新行----------------//
function tableAdd() {
var newRow;
var rownum = table_elment.rows.length;
newRow=table_elment.insertRow(rownum);
newRow.id="r"+rownum;

+'<input type="text" id="depname'+rownum+'" name="depname" value="${loginer.str_DepName}"'
+'onClick="SelectWorkGroup4('+rownum+',/'${loginer.strOpFac}/')"'

cont++;
}

// ----------------- 删除当前行 ----------------- //
function tabledel() {
var trIndex = getRowIndex();

table_elment.deleteRow(trIndex);

// -------------- 获取当前行的索引 ------------- //

}
var intRowIndex = Elm.rowIndex;

}
catch(ex)
{

// -------------- 新增一行的代码示例 ------------- //

<input type="button" class="fm" onclick="tableAdd()"
id="add" value="新增">

// -------------- 删除一行的代码示例 ------------- //
