ClientScript.RegisterClientScriptBlock对象错误

Question

 var path;
 function initialize() {   
    var polyOptions = { strokeColor: '#FF0000', strokeOpacity: 1.0, strokeWeight: 2 }
    path = new google.maps.Polyline(polyOptions);
}

function drawpoly1() { 
path.getPath().push(location);
}

我从.Net调用这个函数，通过

ClientScript.RegisterClientScriptBlock

函数被调用，但它将错误显示为

请告诉我如何处理此错误

嗨，我建议从服务器端用户ClientScript.RegisterClientScriptBlock本身调用这两个函数，因为一旦你将回发你的页面，你将丢失客户端脚本，很明显，你将找不到你声明的客户端的对象和定义。下面我展示的例子可能会对你有所帮助，试试这个：

protected void btn_Click(object sender, EventArgs e)  {    
    System.Text.StringBuilder sb = new System.Text.StringBuilder();    
    sb.Append("<script language='javascript'> var lbl; function Initialize() {");        
    sb.Append("lbl = 'lblDisplayDate';"); sb.Append("}</script>"); 

     if (!ClientScript.IsClientScriptBlockRegistered("JSScriptBlock"))    {
            ClientScript.RegisterClientScriptBlock(this.GetType(), "JSBlock", sb.ToString());   
           }

          string funcCall = "<script language='javascript'>Initialize();</script>"; 

          if (!ClientScript.IsStartupScriptRegistered("JSScript"))   { 
            ClientScript.RegisterStartupScript(this.GetType(), "JSScript", funcCall);   
          }
   }
