setInterval 有参数定时执行

function refreshStatus(){
	var idarr = new Array();
	$(".locState span").each(function(){
		idarr.push(this.id);
		
	});
	alert(idarr)
	iCount = setInterval( function ()
     {
        startRequest(idarr);
    },1000);
}
	

function startRequest(idarr){
		alert(idarr);
}

无参数：

<pre name="code" class="javascript">function getFileList(){
	iCount = setInterval("startRequest()",1000);
}
