我有一个项目，我在其中动态生成一行单元格。说得更清楚，在我的场景中，我连续有8-9个细胞。第一个和第二个单元格是按钮，之后是文本框。现在页面加载时会自动添加5 rows。当用户填充这5行中的数据，并且他/她到达最后一行时，在最后一行的最后一个单元格的标签后，生成新的5行。
我使用JavaScript完成了这项工作。现在，当我添加这5个新行时，无法在新生成的行的first textbox (3rd cell)上实现焦点。如何将焦点设置在新生成的行的文本框上？
我的行代码：
function onRowDoubleClick_Add_Row(id, rowNo)
{
var New_RowNo = (parseInt(rowNo) + parseInt(1));
var table = document.getElementById('<%= tblItem.ClientID %>');
var rowCount = table.rows.length;
var row = table.insertRow(rowCount);
row.setAttribute("class", "gridRow");
// Delete
var cell11 = row.insertCell(0);
cell11.setAttribute("style", "width:20px;");
var C11_element2 = document.createElement("input");
var C11_EID = "MainContent_Image" + New_RowNo + "_" + New_RowNo + "_A_" + New_RowNo; //"MainContent_Image10_A_10"
var C11_EName = "ctl00$MainContent$Image" + New_RowNo + "_" + New_RowNo + "_A_" + New_RowNo; //"ctl00$MainContent$Image10_A_10"
C11_element2.type = "image";
C11_element2.setAttribute("src", "Images/collapse.gif");
C11_element2.setAttribute("title", "Delete");
C11_element2.setAttribute("id", C11_EID.toString());
var click = "return window.confirm('Are you sure you want to delete this item');";
C11_element2.setAttribute("Click", click);
C11_element2.setAttribute("name", C11_EName);
//var blur = "onRowDoubleClick_Add_Row('Image" + New_RowNo + "_A_" + New_RowNo + "','" + New_RowNo + "');";
//C11_element2.setAttribute("onblur", blur);
var Check_Delete = "Check_Delete('Image" + New_RowNo + "_A_" + New_RowNo + "');";
//C11_element2.setAttribute("onmousedown", Check_Delete);
cell11.appendChild(C11_element2);
// Iten Number
var cell1_1 = row.insertCell(1);
cell1_1.setAttribute("style", "width:25px;padding-right:5px;");
var C1_element1_1 = document.createElement("input");
C1_element1_1.type = "text";
C1_element1_1.setAttribute("style", "width:100%;");
C1_element1_1.setAttribute("id", "MainContent_txtItem" + New_RowNo);
var blur = "getItemNoValue('txtItem" + New_RowNo + "','" + New_RowNo + "','" + New_RowNo + "','A_" + New_RowNo + "','A_');";
C1_element1_1.setAttribute("onblur", blur);

cell1_1.appendChild(C1_element1_1);

不要查看代码的长度。在此代码中，您将看到onRowDoubleClick_Add_Row方法。我在最后一行的最后一个单元格的blur上调用此方法。此功能new 5 rows添加后，焦点丢失。焦点应该在新生成的行部分的// item number上。
