javascript - 使用 JavaScript 调用事件 click

Question

可以用 JavaScript 调用事件 click 吗？怎么办？

我试图在单击按钮时调用此事件。

我动态创建按钮，因此 id 不断变化

这是我如何动态制作按钮并分配事件点击

protected void Page_Init(object sender, EventArgs e)
        {
            ScriptManager.RegisterStartupScript(this, this.GetType(), "Pop", "showAndHide();", true);

            Button Btn_clic = (Button)sender;
            var name = Btn_clic.Text;

            List.ListUsers listArea = new List.ListUsers();
            List<Data.Area> Area = listArea.AreaList();

            List<Data.Area> ListOfEquiposOk = Area.Where(x => x.AREA == name && x.STANDBY == 0).ToList();

            List<Button> Botones = new List<Button>();

            var TeamFCH = ListOfEquiposOk.Select(x => x.TEAM).Distinct().ToList();

            foreach (var team in TeamFCH)
            {
                Button newButton = new Button();
                newButton.CommandName = "Btn" + Convert.ToString(team);
                newButton.ID = "Btn_" + Convert.ToString(team);
                newButton.Text = team;
                newButton.CommandArgument = name;

                newButton.Click += new System.EventHandler(newButton_Click);


                Botones.Add(newButton);

                GoodPanel.Controls.Add(newButton);
                newButton.CssClass = "btn-primary outline separate";
            }
        }

protected void newButton_Click(object sender, EventArgs e)
        {
            ScriptManager.RegisterStartupScript(this, this.GetType(), "Pop", "ModalGood();", true);

            Button Btnclick = (Button)sender;
            var team = Btnclick.Text;
            string name = Btnclick.CommandArgument;

            List.ListUsers listArea = new List.ListUsers();
            List<Data.Area> Area = listArea.AreaList();

            List<Data.Area> ListOfToolsOk = Area.Where(x => x.AREA == name && x.TEAM == team && x.STANDBY == 0).ToList();

            var ToolArea = ListOfToolsOk.Select(x => x.TEAM);
            Grv_Eng.DataSource = ListOfToolsOk;
            Grv_Eng.DataBind();
        }

如果您想分配 OnClick 事件，请按如下操作。

Button Btnclick = new Button();
Btnclick.Click += newButton_Click;
Btnclick.Text = "MyButton";
Btnclick.ID = "MyButtonID";

PlaceHolder1.Controls.Add(Btnclick);

如果您想引用动态 ID，请在 aspx 页面上使用 FindControl 和 ClientID。

document.getElementById("<%= PlaceHolder1.FindControl("MyButtonID").ClientID %>").click
