JS 获取某个容器控件中id包含制定字符串的控件id列表

//获取某容器控件中id包含某字符串的控件id列表
//参数：容器控件、要查找的控件的id关键字 
function GetIdListBySubKey(container,subIdKey)
{
    var idList = "";
  var child=container.childNodes;
  var chileLength=child.length;
    for(var i = 0; i < container.childNodes.length;i++)
    {
        if(container.childNodes[i].attributes != null && container.childNodes[i].attributes["id"] != undefined && container.childNodes[i].id.indexOf(subIdKey) > -1)
        {
            idList += container.childNodes[i].id + ",";
        }
        if(container.childNodes[i].childNodes.length > 0)
        {
            idList += GetIdListBySubKey(container.childNodes[i],subIdKey)
        }
    }
    return idList;
} 

//调用
var doms=GetIdListBySubKey(document,"Money"); //document
console.log(doms);

//改进：直接返回控件数组
代码如下:

//改进：直接返回控件数组
//获取某容器控件中id包含某字符串的控件数组
//参数：容器控件、要查找的控件的id关键字
//返回值：查找到的控件数组
function GetConListBySubKey(container,subIdKey)
{
    var reConArry = [];
    for(var i = 0; i < container.childNodes.length;i++)
    {
        if(container.childNodes[i].attributes != null && container.childNodes[i].attributes["id"] != undefined && container.childNodes[i].id.indexOf(subIdKey) > -1)
        {
            reConArry.push(container.childNodes[i]);
        }
        if(container.childNodes[i].childNodes.length > 0)
        {
            var re = GetConListBySubKey(container.childNodes[i],subIdKey)
            for(var k = 0;k<re.length;k++)
            {
                reConArry.push(re[k]);
            }
        }
    }
    return reConArry;
}
