通过servlet打开本地图片

//li点击事件
	    $("#fileul").on("click","#fileli",function(){
	    	//图片格式
	    	var strFilter=".jpeg|.gif|.jpg|.png|.bmp|.pic|";

	    	var path=$(this).attr("path");
	    	var str=(path.substring(path.lastIndexOf('.'),path.length)).toLowerCase();
	    	if(strFilter.indexOf(str)>-1){//后缀是图片格式时才打开
	    		var filepath=parent.window.globedataserverurl + "/OpenImages?filepath="+path;//图片路径

		    	var bheight=$("body",window.parent.document).height();//获取body高度
		    	var bwidth=$("body",window.parent.document).width();//获取body宽度
		    	parent.showImagesDialog(filepath,bheight/5,bwidth/3);
	    	}
	    });
