javascript - 在gridview rowdatabound中设置onclientclick后javascript没有触发

Question

我想触发一个 javascript 来确认删除该行。

这是行数据绑定

Private Sub GridSlide_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridSlide.RowDataBound
    If e.Row.RowType = DataControlRowType.DataRow Then
        DirectCast(e.Row.FindControl("LinkDelete"), LinkButton).Attributes.Add("OnClientClick", "javascript:DeleteSlide('" & Convert.ToString(e.Row.RowIndex) & "')")
    End If

End Sub

这是javascript

function DeleteSlide(var_row) {
    var blnResponse = null;
    var strMessage = '';
    try {
        strMessage = 'Are you sure you want to delete this slide data?';
        blnResponse = window.confirm(strMessage);
        if (blnResponse) {
            __doPostBack('DeleteSlide()', var_row  );
        }
    }
    catch (Err) {
        alert('DeleteSlide - ' + Err.description);
    }
}

但是当我单击删除链接按钮时，javascript 不会触发。

有什么问题？

PS 我尝试使用 CommandArgument 和 Container.DataItemIndex 但这会导致更多错误，所以我最终使用了 rowdatabound。

尝试这个：

DirectCast(e.Row.FindControl("LinkDelete"), LinkButton).OnClientClick = "javascript:DeleteSlide('" & Convert.ToString(e.Row.RowIndex) & "')";
