这样写为什么不能动态增加一行?我应该怎样修改
function insertRows(){ var tempRow=0; var tbl=document.getElementById("dictTbl"); tempRow=tbl.rows.length; //获取当前table的行数 var Rows=tbl.rows;//类似数组的Rows var newRow=tbl.insertRow(tbl.rows.length);//插入新的一行 var Cells=newRow.cells;//类似数组的Cells for (i=0;i<4;i++)//每行的3列数据 { alert("进入"); var newCell=Rows(newRow.rowIndex).insertCell(Cells.length); alert("过去"); newCell.align="center"; switch (i) { case 0 : newCell.innerHTML="<td align=\"center\"><input type=\"checkbox\"/></td>";break; case 1 : newCell.innerHTML="<td align=\"center\" width=\"120px\">" + "</td>";break; case 2 : newCell.innerHTML="<td align=\"center\"\><input id=\"classifyName\" name=\"classifyName\" type=\"text\" size=\"50\" maxlength=\"25\"/></td>";break; case 3 : newCell.innerHTML="<td width=\"400px\"></td>";break; } } }...
