Javascript调用C#静态函数

Client Code

function WriteLog( assetID, billID, billState, bizType, logInfo, linkUrl, note )
{
    var tmp = new CSFunction();
    tmp.AsseblyName = "ZCGL_Com.dll";
    tmp.TypeName = "Genersoft.JTGL.ZCGL.ZCGL_Com.AssetLogMgr";
    tmp.FunctionName = "WriteLog";
    tmp.AddParameter( "string", assetID );
    tmp.AddParameter( "string", billID );
    tmp.AddParameter( "string", billState );
    tmp.AddParameter( "string", bizType );
    tmp.AddParameter( "string", logInfo );
    tmp.AddParameter( "string", linkUrl );
    tmp.AddParameter( "string", note );
    var rtn = tmp.Execute();
    tem = null;
    return rtn;
}

Javascript 核心调用类

function CSFunction()
{
    this.AsseblyName = "";
    this.TypeName = "";
    this.FunctionName = "";
    this._paramString = "";
    this._split0 = "#;#";
    this._split1 = "#:#";
    this.AddParameter = function( type, value )
    {
        var exps = type + this._split1 + value + this._split0;
        this._paramString += exps;
    }
    this.Execute = function()
    {
        if( this.AsseblyName == "" )
        {
            window.alert( "缺少程序集参数" );
            return false;
        }
        if( this.TypeName == "" )
        {
            window.alert( "缺少类名参数" );
            return false;
        }
        if( this.FunctionName == "" )
        {
            window.alert( "缺少方法名参数" );
            return false;
        }
        var param = "";
        param += "asmb" + this._split1 + this.AsseblyName + this._split0;
        param += "type" + this._split1 + this.TypeName + this._split0;
        param += "func" + this._split1 + this.FunctionName + this._split0;
        param += this._paramString;
        param = escape( param );
        var xhttp= new ActiveXObject("Microsoft.XMLHTTP");
        try
        {
            xhttp.open("GET", "../../Public_Web/ExecCSFunction.aspx?param="+param, false);
            xhttp.send();
            var vsRetval = xhttp.responseText;       
            xhttp = null;
            if( vsRetval.substring( 0, 2 ) == "/1" )    { window.alert( vsRetval.substring( 2 ) ); return false; }
            return vsRetval;
        }
        catch(error)
        {
            window.alert( "CSFunction处理失败:" + error.description );
            return false;
        }   
    }
}
