Prevent iframe refresh

[PeggyFree]

Hello,

Thank you for this precious plugin. I'll deal with json data later. For now I could'nt find a way to prevent grafana from refreshing the ajax/iframe panel. It makes my ajax panel unusable as is. How do you deal with this?

Check that your url is not changing with every request and make sure you have the setting to only reload when the url changes

Wait, actually... the 'only changes' check does not apply to iframe, but changes to the URL will cause the iframe to update

Thank you for your help. To be honnest I don't understand the role of the javascript parameters, I let them by default :

`{ from:ctrl.range.from.format('x'), // x is unix ms timestamp

to:ctrl.range.to.format('x'),

height:ctrl.height,

now:Date.now(),

interval: ctrl.template('$__interval'),

sample: 'Not escaped: $__interval',

since:ctrl.lastRequestTime }`

Do I need to change this code? I don't see a refresh command, but I may be wrong from the beginning. I just put a webcam url as an iframe.

If you don't need the parameters to change based on the page, you can remove all of them... but if that is the case, you can also just use the built-in text panel with html:

<iframe src=....

Thank you for your answer, now it is perfect. Ajax was not necessary for my need, indeed. I'll use it later for other needs. I'll have to send rest calls to Octoprint soon.
