推荐答案

谈到带有计时器的Asp和网页，我们说的是java脚本。不是吗？！如果您必须知道浏览器可能会在不同情况下停止java脚本。除了更改应用程序逻辑之外，你无法阻止它。

Speaking about Asp and webpages with timer mean we are talking about java script. Isn''t it?! If you you must to know that browser may stop java script in different cases. There is no way you can prevent it except changing your application logic.
