javascript - 如何在C#代码后面编写Javascript代码？

Question

我正在动态创建文本框，那么如何为文本框“onchange”事件调用下面的 javascript 函数？

<script type="text/javascript">
    debugger;
    function myFunction() {
        var btn = document.getElementById('<%= temp.ClientID%>').value;
        var btntemp = document.getElementById('<%= txttemp2.ClientID%>').value;
        var val = parseInt(btn) + parseInt(btntemp);
        document.getElementById('<%= TextBox1.ClientID%>').value = val;
    }        
</script>
<asp:TextBox ID="temp" runat="server" onchange="myFunction()"></asp:TextBox>
   <asp:TextBox ID="txttemp2" runat="server" onchange="myFunction()"></asp:TextBox>

这里我动态创建textboxex。

Table table = (Table)this.Page.FindControl("PlaceHolder1").FindControl("Table1");
for (int i = 0; i < rowsCount; i++)
 {
   for (int j = 0; j < colsCount; j++)
    {
     TextBox tb = (TextBox)table.Rows[i + 1].Cells[j].FindControl("TextBoxRow_" + i + "Col_" + j);
     tb.Text = Request.Form["TextBoxRow_" + i + "Col_" + j];

这里我正在获取第一列的文本框值

else if (j == 2)
 {
   int quantityText;
   TextBox quantity = (TextBox)table.Rows[i +1].Cells[j].FindControl("TextBoxRow_" + i + "Col_" + j);

这里我正在获取第二列的文本框值

else if (j == 3)
  {
    double rateText;
    TextBox rate = (TextBox)table.Rows[i + 1].Cells[j].FindControl("TextBoxRow_" + i + "Col_" + j);

这里我动态生成文本框。

private void GenerateTable(int rowsCount)
 {
  Table table = new Table();
            table.ID = "Table1";
            PlaceHolder1.Controls.Add(table);
           for (int i = 0; i < rowsCount; i++)
            {
                TableRow row = new TableRow();
                row.ID = "Row_" + i;
                else if (j < colsCount - 1)
                    {
                        TableCell cell = new TableCell();
                        TextBox tb = new TextBox();
                      tb.ID = "TextBoxRow_" + i + "Col_" + j;
                      cell.Controls.Add(tb);
                     row.Cells.Add(cell);
                    }

用它来调用后台代码中的 javascript 函数

ClientScript.RegisterClientScriptBlock(myFunction(), "AlertMsg", "<script> 
                              alert('Inserted successfully');</script>", true)
