我在Textbox中有一个GridView如果文本框中的文本已更改,我想更改Label.Text。但是我无法调用用.cs页编写的javascript函数。 TbUnitCost_TextChanged方法中是否有任何错误。

这是我的aspx页面

<ItemTemplate>
  <asp:TextBox Style="text-align: right" ID="TbUnitCost" runat="server" Width="80px" Text='<%#Bind("Unit_Cost")%>' AutoPostBack="true" OnTextChanged="TbUnitCost_TextChanged"  TextMode="Number"></asp:TextBox>
 </ItemTemplate>


Page后面的代码如下

 protected void TbUnitCost_TextChanged (object sender, EventArgs e)
    {
        GridViewRow currentRow = (GridViewRow)((TextBox)sender).Parent.Parent;
        int rowNo = currentRow.RowIndex;
        string gridName = "GridWorkExpenses";
        TextBox tbunitCost = (TextBox)currentRow.FindControl("TbUnitCost");
        int row = Convert.ToInt32(tbunitCost.Text);

        tbunitCost.Attributes.Add("onchange","javascript:calculateTotalCost('"+rowNo+"','"+gridName+"');");

    }


而javascript函数是:

<script type ="text/javascript">
    function calculateTotalCost(rowNo, GridName) {

        if (GridName== 'GridWorkExpenses') {
            var rowscount = document.getElementById('<%=GridWorkExpensesSheet.ClientID%>').rows.length;
            return calculateTotalUnitCost("GridWorkExpensesSheet", rowscount,rowNo);
        }
   }
 </script>

最佳答案

尝试使用此:

ScriptManager.RegisterClientScriptBlock(this, this.GetType(), "Script", "CalculateTotalCost", true);


描述任何进一步的问题(如果有)。
