Question

我想在用户点击按钮时测试C＃代码端，C＃函数中的方法应该能够调用JavaScript函数来显示警告C＃公共变量的结果。不知何故，它根本不会调用任何东西。在ButtonRequest_Click函数的底部，我写了Page.ClientScript.RegisterStartupScript(this.GetType(), "CreateIsm();", "CreateIsm();", true);来在JavaScript中调用CreateIsm();函数。也许这不起作用？

这是C＃代码，

public Collection<PSObject> output = new Collection<PSObject>();
    public string deviceName = "";
    public string ipAddresses = "";
    public string YourScript = "";

protected void ButtonRequest_Click(object sender, EventArgs e)
    {
        deviceName = string.Empty;
        ipAddresses = string.Empty;
        HiddenName.Visible = false;

        string str = "";
        string ipAddress = "";
        string name = "";

        var tbids = (List<string>)Session["tbids"];

        //create a powershell
        Runspace runSpace = RunspaceFactory.CreateRunspace();
        runSpace.Open();

        RunspaceInvoke invoke = new RunspaceInvoke();

        Pipeline pipeline = runSpace.CreatePipeline();

        Command invokeScript = new Command("Invoke-Command");

        //Add powershell script file and arguments into scriptblock
        ScriptBlock sb = invoke.Invoke(@"{D:\Scripts\Get-FreeAddress.ps1 '" + DropDownListContainer.SelectedValue + "' " + DropDownListIP.SelectedValue + "}")[0].BaseObject as ScriptBlock;

        invokeScript.Parameters.Add("scriptBlock", sb);

        invokeScript.Parameters.Add("computername", TextBoxServer.Text);

        pipeline.Commands.Add(invokeScript);

        Collection<PSObject> output = pipeline.Invoke();
        runSpace.Close();
        Runspace runSpace2 = RunspaceFactory.CreateRunspace();
        runSpace2.Open();


        foreach(PSObject psObject in output)
        {
            ipAddress = "" + psObject;
            ipAddresses += "" + psObject;

            foreach(var id in tbids)
                try
                {
                    name = Request[id];
                    deviceName += Request[id] + "\r\n";

                    Pipeline pipeline2 = runSpace2.CreatePipeline();
                    Command invokeScript2 = new Command("Invoke-Command");

                    //Add powershell script file and arguments into scriptblock
                    ScriptBlock sb2 = invoke.Invoke(@"{D:\Scripts\Set-IPAddress.ps1 " + ipAddress + " " + name + "}")[0].BaseObject as ScriptBlock;

                    invokeScript2.Parameters.Add("scriptBlock", sb2);

                    invokeScript2.Parameters.Add("computername", TextBoxServer.Text);

                    pipeline2.Commands.Add(invokeScript2);


                    tbids.RemoveAt(0);

                    Collection<PSObject> output2 = pipeline2.Invoke();

                    foreach(PSObject psObject2 in output2)
                    {
                        str = str + psObject2;
                    }

                    break;
                }
                catch
                {

                }

        }


        Page.ClientScript.RegisterStartupScript(this.GetType(), "CreateIsm();", "CreateIsm();", true);

    }

html中的aspx方面的Javascript，

<%@ Page Title="Home Page" Language="C#" AutoEventWireup="true"
    CodeFile="Default.aspx.cs" CodeBehind="~/Default.aspx.cs" Inherits="_Default" %>

    <script>

     CreateIsm = function (funct) {

您可以像这样使用OnClientClick：

<asp:button id="Button1" runat="server" OnClientClick="return confirm('Ok to post?')" onclick="Button1_Click" Text="Click!" />

为什么C＃button_clicked函数后面的代码不调用Javascript函数？
