I've had a look at it but unable to get anything working from it, the closest thing I have to what I need is the Websters code, it nearly suits my needs. Did it really work for you? Add a comment.

As the table size is so big is it possible to cycle through each table block and update ones what are different? How reliable is this? I have a requirement to refresh an image once a minute in a browser for monitoring an industrial process. Alternatively, you can use the false keyword to reload the page from the cache. You can also use JavaScript to refresh the page automatically after a given time period.

Here, we are refreshing the page 5 seconds after the page loads. This results in the page continuously refreshing every 5 seconds. You can achieve the same effect using the HTML meta tag. Use this countdown example to notify users for upcoming events or a deal that is going end very soon, etc.

The JavaScript setInterval method can be used for a variety of purpose, using various execution methods, such as a button click. I have just showed two simple examples on how to use the method to execute a function automatically and repeatedly. This in case you do not want to use JavaScript or jQuery for this purpose. I have a JSP page which has to display the status of various jobs that are running. Some of these jobs take time, so it takes a while for their status to change from processing to complete.

Is it a good idea to have a javascript function that would refresh the page every 30 seconds or so? Are there any ramifications for having a script that is constantly refreshing a page? There are multiple solutions for this. If you want the page to be refreshed you actually don't need JavaScript, the browser can do it for you if you add this meta tag in your head tag.

If you really want to do it with JavaScript, then you can refresh the page every 30 seconds with Location. If you don't need to refresh the whole page but only a part of it, I guess an AJAX call would be the most efficient way. If you want refresh the page you could use like this, but refreshing the page is usually not the best method, it better to try just update the content that you need to be updated.

Use setInterval instead of setTimeout. Though in this case either will be fine but setTimeout inherently triggers only once setInterval continues indefinitely. Stack Overflow for Teams — Collaborate and share knowledge with a private group.
