如何顯示JavaScript確認對話框並在GridView C＃asp.net中運行功能？

Question

當我刪除GridView行時，我想顯示JavaScript確認對話框並運行一個函數。 你是怎樣做的？

像這樣：

protected void GridViewActivities_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if(e.Row.RowType == DataControlRowType.DataRow)
        {
            LinkButton lb = (LinkButton)e.Row.FindControl("LinkButton1");
            lb.Attributes.Add("onClick", "return confirm('You are sure?'); + MyFunction()");
        }
    }

如果要基於確認框結果運行函數，請嘗試以下代碼

protected void GridViewActivities_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if(e.Row.RowType == DataControlRowType.DataRow)
        {
            LinkButton lb = (LinkButton)e.Row.FindControl("LinkButton1");
            lb.Attributes.Add("onclick", "var result = confirm('You are sure?'); if(result) { MyFunction(); } return true; ");
        }
    }

如果要運行功能而不考慮確認框的結果，請嘗試以下代碼：

protected void GridViewActivities_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if(e.Row.RowType == DataControlRowType.DataRow)
        {
            LinkButton lb = (LinkButton)e.Row.FindControl("LinkButton1");
            lb.Attributes.Add("onclick", "confirm('You are sure?'); MyFunction(); return true; ");
        }
    }
