C# 脚本块寄存器

Question

任何人都可以帮助我，因为我试图先注册一个脚本并使用 C# 将一个名为 "DoClick()" 的函数绑定到按钮中，但在运行时发生了一些错误。请在下面查看我的代码。这样当按钮被点击时，他们调用函数“DoClick()。谢谢大家

public void regiterAdsScript(int loc)
{
    string adsLink = ads_link(loc);       
    // Define the name and type of the client script on the page.
    String csName = "ButtonClickScript";
    Type csType = this.GetType();
    // Get a ClientScriptManager reference from the Page class.
    ClientScriptManager cs = Page.ClientScript;
    // Check to see if the client script is already registered.
    if (!cs.IsClientScriptBlockRegistered(csType, csName))
    {
        StringBuilder csText = new StringBuilder();
        csText.Append("<script type=\"text/javascript\"> \n");
        csText.Append("function DoClick() { <script type='text/javascript' src='//abcd.site?id=123'></script> }  \n");
        csText.Append("</script>");
        cs.RegisterClientScriptBlock(csType, csName, csText.ToString());
        Button1.Attributes.Add("onClick", "return DoClick()");

    }
}

你的脚本注册码应该是这样的

Button1.Attributes.Add("onClick", "javascript:DoClick();");

此外，您的脚本看起来不对。无论你想让你的脚本做什么，都应该在函数声明之后。如果你想发出警报，它应该是这样的

csText.Append("function DoClick() { alert('MK'); }  \n");

您还需要在调用 Button1_Click 之前调用函数 regiterAdsScript()。我在 Page_load 本身中调用了它。以下是您的示例程序：

protected void Page_Load(object sender, EventArgs e)
{
    regiterAdsScript();  
}
protected void Button1_Click(object sender, EventArgs e)
{
    //functionality to be implemented
}
public void regiterAdsScript()
{
    string adsLink = ads_link(loc);
    // Define the name and type of the client script on the page.
    String csName = "ButtonClickScript";
    Type csType = this.GetType();
    // Get a ClientScriptManager reference from the Page class.
    ClientScriptManager cs = Page.ClientScript;
    // Check to see if the client script is already registered.
    if (!cs.IsClientScriptBlockRegistered(csType, csName))
    {
        StringBuilder csText = new StringBuilder();
        csText.Append("<script type=\"text/javascript\"> \n");
        csText.Append("function DoClick() { alert('MK'); }  \n");
        csText.Append("</script>");
        cs.RegisterClientScriptBlock(csType, csName, csText.ToString());
        Button1.Attributes.Add("onClick", "javascript:DoClick();");
    }
}
