如何在JavaSript中使用ASP.NET LinkBut​​ton [英] How to use ASP.NET LinkButton with JavaSript

问题描述

大家好，
我想将ASP.NET LinkBut​​ton与JavaSript一起使用，

我正在使用没有回发功能的Client CallBack，

我的JavaScript是:

Hi guys,
I want to use ASP.NET LinkButton with JavaSript,

i am using Client CallBack without postback,

my javascript is:

<<pre lang="xml">script type="text/javascript">
function ReceiveBikeColor(colorFile)
{
    // any code here
}

<pre lang="cs">public partial class About : System.Web.UI.Page, ICallbackEventHandler
{
    protected void Page_Load(object sender, EventArgs e)
    {
        string cbRef = ClientScript.GetCallbackEventReference(this, "arg", "ReceiveBikeColor", "context");
        string cbScript = "function GetBikeColor(arg, context) {" + cbRef + "; }";
        ClientScript.RegisterClientScriptBlock(this.GetType(), "GetBikeColor", cbScript, true);
    }

    public string GetCallbackResult()
    {
        //////////
    }
    public void RaiseCallbackEvent(string eventArgument)
    {
        ///////
    }
}

但是在将onclick属性分配给Javascript方法时，如下所示:

but when assign onclick attribute to Javascript method like that:

<asp:LinkButton id="lbtnAddToFavorites" runat="server"  OnClick="GetBikeColor()" >Add to favorites</asp:LinkButton>

它告诉我:

错误"ASP.specifictopic_aspx"不包含"GetBikeColor"的定义

并在使用OnClientClick属性时将其打​​包为Postpack

it tell me that:

Error ''ASP.specifictopic_aspx'' does not contain a definition for ''GetBikeColor''

and when use OnClientClick attribute it casue Postpack

<asp:LinkButton id="lbtnAddToFavorites" runat="server"  OnClientClick="GetBikeColor()" >Add to favorites</asp:LinkButton>

推荐答案

尝试这种方式

try that way

function GetBikeColor()
{
//Some Implementation
return false;
}

<asp:LinkButton id="lbtnAddToFavorites" runat="server"  OnClientClick="return GetBikeColor();" >Add to favorites</asp:LinkButton>

如果您试图在有人单击LinkBut​​ton时调用js函数，则可以使用OnClientClick.

确保定义了函数GetBikeColor并可以访问.

LinkBut​​ton.OnClientClick属性 [ LinkBut​​ton.OnClick方法 [

If you''re trying to call a js function when someone clicks the LinkButton, OnClientClick is the way to go.

Make sure you defined the function GetBikeColor and that it''s accessible.

LinkButton.OnClientClick Property [^]

LinkButton.OnClick Method [^]

Hope this helps!

这是正确的吗?，请使用onclientclick调用javascript.
再次尝试.祝您好运.
