通过这个示例我们实现通过attachmentImage上传的图片在grid表格中显示,分成两个步骤:

1.引入DocUtils:

DocUtils = require('$UI/system/components/justep/docCommon/docUtil');

2.通过grid的cellRender方法来显示图片

例:

Model.prototype.imageGridCellRender = function(event){
		if(event.colName == "image"){
			if (event.colVal != null && event.colVal != "" && event.colVal != "[]") {
				//解析数据库中存储的json数据
				var imageJson = eval("(" + event.colVal + ")");
				var fileID = imageJson[0]["fileID"];
				var docPath = imageJson[0]["docPath"];
				//依靠上述解析出的信息获得路径
				var url = DocUtils.InnerUtils.getdocServerAction({
				     "docPath" : docPath,
				     urlPattern : "/repository/file/view/" + fileID + "/last/content",
				     isFormAction : false,
				     context : this.getContext()
			    });
				//显示图片
				event.html = "<img src="+url+" xid='image1' style='height:70px;width:70px;'></img>"
			}
		}
	};

效果图:
