//批处理方式异步获取评论记数，并填充页面 by tangwei 07.03.23 modify 07.03.23

//-----------公共函数-------------//

//根据ID取得dom对象
function $(id) {
	return document.getElementById(id);
}
//去掉末尾的符号
function myRTrim(str, trimStr)
{
    var s = new String(str);
    if (trimStr.indexOf(s.charAt(s.length-1)) != -1)
    {
        var i = s.length - 1;
        while (i >= 0 && trimStr.indexOf(s.charAt(i)) != -1){i--;}
        s = s.substring(0, i+1);
    }
    return s;
}


//-----------串联需要获取评论记数的日志，统一获取并返回填充页面-------------//
var _FeedbackCountStack = "";  //需要获取评论记数的文章ID列表
var _FeedbackCountResult = ""; //获取评论记数的结果

//添加需要获取记数的文章ID
function AddFeedbackCountStack(ID)
{   
    _FeedbackCountStack += ID + ",";
}

//获得记数
function LoadFeedbackCount()
