Spotfire: How to reload/refresh a text area html through Javascript
Question
I have an HTML page which auto refreshes itself every 5 sec. This page contains 3 image from 3 different server which i want to show side by side and and refresh every 5 second.
<!DOCTYPE html> <html> <head> <meta http-equiv="content-type" content="text/html; charset=UTF-8" /> <title>HMI Remote Monitoring</title> <meta http-equiv="refresh" content="5" > </head> <body> <table> <tr> <td>Chamber 1:100.206.214.19</td> <td>Chamber 2:100.206.214.122</td> <td>Chamber 3:100.206.214.145</td> </tr> <tr> <td> <img border="2" src="http://100.206.214.19/remote/display.bmp" alt="" name="displayImage" width="400" height="240"> </td> <td> <img border="2" src="http://100.206.214.122/remote/display.bmp" alt="" name="displayImage" width="400" height="240"> </td> <td> <img border="2" src="http://100.206.214.145/remote/display.bmp" alt="" name="displayImage" width="400" height="240"> </td> </tr> </table> </body> <html>
I am using the http-equiv to refresh the html and it works fine when it's an HTML page in Collaboration view. but now I need to move this same html into a Text area visualization and the refresh doesn't work there.(Mainly coz collaboration dont accept static HTML and i'll have to keep a server running somewhere to keep the html alive.Doable but not a nice solution.)
I know a few alternatives such as using iron-python to reload the html content of the text area(Feels like a overkill + making it sleep in a loop will freeze the viz - will be an unnecessary challenge) or just use the images as labels(it has it's own challenges and is subject of another question I have raised already.) But I was wondering if there's a way we could use JavaScript(clearly I'm bad with JS, so couldn't crack it.) to reload the text area content?
Thanks for your solutions and ideas.
