如何通过GridView将复选框选中的行索引传递给JavaScript

Question

I have a gridview and i want to pass rowindex value to javascript. I tried with following code but its not working.

In Gridview

<asp:TemplateField>
     <ItemTemplate>
        <asp:CheckBox ID="chkSelect" runat="server"  onclick="javascript:return checkSts('<%# DataBinder.Eval(Container.DataItemIndex) %>')" />
     </ItemTemplate>
</asp:TemplateField> 

In Javascript:

function checkSts(i) {  alert(i); }

Answer 1

You can type it as

<input type="checkbox" onclick="return checkSts('<%#Eval("FieldName")%>')" />

and work.

Alternative with asp:checkbox

<asp:CheckBox runat="server" ID="chBEna" onclick='<%#getCode(Container.DataItem)%>' />

and on code behind

protected string getCode(object oItem)
{
    string cPid = DataBinder.Eval(oItem, "FieldName").ToString();

    return "return checkSts('" + cPid + "')";
}

both checked and works.

Answer 2

You can get rowindex of element by using parentElement to reach to the row in which particular elemnt is nested

eg.

onclick="callme(this)"

function callme(obj)
{
  obj.parentElement.parentElement.rowIndex--- this wud be rowindex of the row.
}
