Widget to display image from web-server does not update image
jimmyhartington opened this issue · comments
I have a simple widget to display an image from a webcam.
The image is located on a web-server I control and is always called the same name.
Is overwritten every minute by my camera.
But the widget seems to cache the image, since it has the same name.
Is it possible to have a widget not cache elements?
Widget code:
# Set the refresh frequency (milliseconds) to every hour
refreshFrequency: 10000
style: """
bottom: 20px // Position widget
right: 20px
widget-align = left
color: #fff
font-family Helvetica Neue
background rgba(255, 255, 255, .1)
padding 20px 20px 20px 20px
border-radius 5px
#container
text-align: widget-align
position: relative
clear: both
.ch-image
max-height: 35vh // allow the img to use up at most 35% of the desktop's height
max-width: 50vw // allow the img to use up at most 50% of the desktop's width
"""
# Render the output.
render: (output) -> """
<div id='container'>
<img class="ch-image" src="https://files.skabertrang.dk/jh/webcams/serverrum/image.jpg">
<div>
"""
If I use the menu command "Refresh All Widgets" the image updates.
If I use an AppleScript to just refresh this widget nothing updates.
tell application id "tracesOf.Uebersicht" to refresh widget id "serverroom-widget-index-coffee"
What if you add a query string with a random number so that url changes each time it refreshes?
I do not know how to do that.
Try:
<img class="ch-image" src="https://files.skabertrang.dk/jk/webcams/serverrum/image.jpg?rnd="""+Math.floor(Math.random() * 999999)+"""">
Thanks. That seems to work consistantly.
