如何在 GridView C# asp.net 中显示 JavaScript 确认对话框并运行函数？

Question

当我删除 GridView 行时，我想显示 JavaScript 确认对话框并运行一个函数。你是怎样做的？类似的东西：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()");        }    }

Answer 1

如果你想根据确认框结果运行你的函数，试试这个代码

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; ");

        }

    }

如果您想在不考虑确认框结果的情况下运行您的函数，请尝试以下代码：

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; ");

        }

    }
