数组 还是 字符串

  var ids = $.map($("#tableadd").bootstrapTable(‘getSelections‘), function (row) {
        return row.id;
    });//数组  弹出框选择id


    var picid = $("#picid").val();//字符串  已选择图片id
	ss = picid.split(",");//字符串转数组
 
	 
	var picids = $.merge(ids, ss); //合并数组
    var nary = picids.sort(); //判断是否有重复提交
		for(var i = 0; i < nary.length - 1; i++)
		{
		if (nary[i] == nary[i+1])
		{
		
		layer.msg(‘提交失败，同一站点请勿重复提交图片！‘);
		$("#box").css("display","none");
		return false;
		//alert("重复内容：" + nary[i]);
		}
		}
