jeesite4 列表页面显示多张图片

private static final String prefixPath = "https://***/patrolimg/userfiles/fileupload";

List<Tpatrol> tpatrols = page.getList();
if (tpatrols != null && tpatrols.size() >0) {
	for (Tpatrol tp : tpatrols) {
		String uid = tp.getUid();
		Tuser tuser = tuserService.get(uid);
		tp.setUid(tuser.getNickname());
		// 将图片url放入img字段中
		String patrolId = tp.getId();
		List<TpatrolImg> imgs = tpatrolImgService.getListByPatrolId(patrolId);
		String img = "";
		if (imgs != null && imgs.size() > 0) {
			for (TpatrolImg tpatrolImg : imgs) {
				img += prefixPath+tpatrolImg.getImg()+",";
			}
		}
		tp.setImg(img);
	}
}

然后在列表页面添加如下代码：

{header:${text("图片")}, name:img, index:a.img, width:300, align:"left", formatter: function(val, obj, row, act){
	var arr = row.img.split(",");
	var str="";
	for(var i=0; i<arr.length; i++){
		var str= str+<img src="+arr[i]+"style="height:80px;">;
	} 
	return str;
}},
