Trying to get a nice display of ping results.  
I tried this suggestion from @Steve-Mcl[Build automatic hyperlink in html table - #3 by Steve-Mcl](https://discourse.nodered.org/t/build-automatic-hyperlink-in-html-table/36832/3) but get an error in the 'convert pingResults to array' function.

Hopeless as I am at javascript, I cannot figure out what the error is.

Now that is a blast from the past.

the function will work, the error is most likely due to recent _improvements_ in the code editor highlighting things that _should_ be done _better_

here is an updated version of the function that should not show any warnings:

```auto
const pingResults = flow.get('pingResults') || {}
const now = new Date()

const tableData = []
for (const k in pingResults) {
    const r = pingResults[k]
    r.age = now.valueOf() - r.timestamp
    if (r.age > 18000) {
        r.state = 'old'
    }
    if (r.state === 'ok') {
        r.rowclass = 'good'
        r.stateInfo = '<i class="fa fa-thumbs-up" aria-hidden="true"></i> OK'
    } else if (r.state === 'ng') {
        r.rowclass = 'bad'
        r.stateInfo = '<i class="fa fa-thumbs-down" aria-hidden="true"></i> NG'
    } else {
        r.rowclass = 'unknown'
        r.stateInfo = '<i class="fa question" aria-hidden="true"></i> ' + r.state
    }
    tableData.push(r)
}

msg.tableData = tableData

return msg;

```

(untested)

That's a super-fast fix-n-reply, thank you! 🙂

Error has gone, but it's not showing on my dashboard.  
I reckon that's because I've forgotten how to use it, although the nodes are on a tab which is showing on the dashboard.

Found it, it's in "Home", I'll try figure out how to move it to "Dashboard".

How do I remove .99 (it's not in the ping list), and increase refresh frequency to reduce "old"?

Thank you.

delete the flow context variable named `pingResults` then run it again.

(look where debug sidebar is, chose the context viewer tab)

Got this working almost brilliantly, one nagging thing is that despite deleting the flow, the old, dummy/test pings till show. They're only there for a few seconds after hitting deploy, but they're still there.

Tried F12 console " localStorage.clear(); "  
Also tried viewing dashboard in completely different browser.

Any ideas as to where it's perhaps caching that data?

Thank you.

_Just tried on my phone - same thing there too....!_

Share your flow and I'll take a look.

hold on, did you delete the flow or the flow context variable?

Show me a screenshot of your flow context (expanded) as well as sharing your flow export.

Try unchecking `Add output messages to stored state` in ui template node.

You can add links and any other properties to the input inject

Where am I now?  
Well, the list became too long so I have split it into Pi and non Pi devices.  
I also found that the default/dummy IPs and the 30 second delay are in the second inject, so changed this to just ping my router and wait for only 3 seconds.

It's working well, and I am certainly interested in trying the suggestion from @E1cid , which I will do when I get a moment.
