如何根据xy坐标和宽度高度安排多个html元素?(How to arrange multiple html elements based on x-y coordinates and width-height?)

我正在开发HTML5中的数字标牌应用程序,其中我将有一个屏幕将播放/显示用户设置的各种媒体。 我有多个元素,比如视频,图像,小工具,股票代码等。我有xy轴的元素和它们的高度/宽度,我想根据给出的信息精确地排列它们。 我将在xml / json中获取数据。

我用普通的CSS尝试过,但它不像预期的那样工作。 我尝试过SVG和Canvas,但他们不支持所有的html元素。


I am developing a digital signage application in HTML5 in which I will have a screen which will be playing/showing various medias setup by user. I have multiple elements like video, images, widgets, ticker etc. I have x-y axis of elements and their height/width, I want to arrange them precisely based on the information given. I will get data in either xml/json.

I have tried with plain CSS, but it not working as expected. I tried SVG and Canvas, but they do not support all the html elemnts.

最满意答案

尝试这个

$query = "update plan  SET plan_files = (case when plan_files IS NULL then '".$filenames."' else concat(plan_files , ',".$filenames."') end ) where plan_id =". $planid;

请确保$ filenames是字符串, $ planid是int。


try this

$query = "update plan  SET plan_files = (case when plan_files IS NULL then '".$filenames."' else concat(plan_files , ',".$filenames."') end ) where plan_id =". $planid;

Please make sure that $filenames is string and $planid is int.
