Thank you. You are dealing with angular. I don't know much about angular.
Tag: template node
JS start looking it now. Thanks, Man I tried, it doesn't seem work. Anytime you need to post a chunk of code or formatted text, put a line before and after it that contains only 3 backtics — that will keep it from escaping your quotes and such.
Please see this post for more information on how to effectively post here. However, your msg. In order for this template to work, you will need to wrap your array in another array, containing this one array. Are you planning on displaying more than one row of data? Ok, here is an example flow with a function that picks a random company name out of a list and a random number for the Stock price.
It puts them in a flow variable and limits the number to 10 entries. Updates happen every 3 seconds. It then sends the array to the template node and you can watch the new entry appear at the top of the list and the 10 entry gets pushed off the bottom.

Now, I want to replace the fixed IP address inside src with the one obtain from hostIP node I placed the following code inside the template node:. Please read the following post How to share code or flow json. I need to insert the IP address as it will be different for different RPi, so the value " How to do it?
My problem is how to insert that address into the template node inside the iframe src. I'm still stack, no solution, no help. Use a debug node on the hostip node to find out what it is sending out. Then change the template node to use he correct variable. Passing msg. Hi, I have a template node to display video from uv4l Inside it the following code works: Now, I want to replace the fixed IP address inside src with the one obtain from hostIP node I placed the following code inside the template node:.
I'm new too but you can link to a gist or a paste text file or just past directly here as quote. How to code the template node to pass the IP address?I've had a lightbulb moment over past 24 hours on how useful the template node can be. Previously, I'd only ever used it in one flow and I'd only copied and pasted it so didn't bother working out what it really doing. But I've just realised it it is a VERY simple way of prefixing and appending text to payloads and means I don't have to write JSONata in change nodes or function nodes to get simple jobs done.
If you have a value lets say a temperature reading in msg. I'm now off to amend my flows. I concur, it is also very nice to use to create 'new' objects.
I am glad that NR has all the flexibility one wants. Yes it is a simplistic example. This is what I've discovered - the template node is really good for simple stuff where all you want to do is re-arrange the msg a bit or add a bit of text to it. Ok I can't figure it out. Assume I have an inject node with msg payload as a string "Good afternoon" and I want to move it to msg.
Can you show me an example because I can't figure out how to do it. The output field for the template node would have to be set to be msg. Be careful to put quotes around the original payload placeholder, unless you can guarantee that the replaced value will not cause some invalid JSON syntax white space, punctuation, etc.
Also, since the "context" of the musctache evaluator is already set to the input msg object, you don't need the "msg. Note that this will cause the existing msg.node red Intput/Output HTML
But for a simple case like that - it would be easier to actually just use a change node. Very very true and simple why do I always forget the 'move' option. I should just give up today. I think I am coming down with a cold and my synapes feel like they are moving thru molasses. Using template node and mustache syntax simply FAQs.
I am trying to send a message after the update of a round slider in an template node written in HTML. This is the code:. Basically I was expecting that a message should be triggered by the command return vol in the function traceEventbut this is not working.
In my experience, it can be even simpler than that -- depending upon what data you are trying to send back to your node-red flow. The angular scope already contains a send msg function, so you can trigger that directly from any angular event in this example, on the ng-click event of the button -- using the plain html onclick event would not have the same access to the angular scope. If you define your traceEvent e function inside the angular scope, it should be available to be called from the slider library something like this, untested :.
If on the other hand you are using the template-ui node as part of the node-red-dashboard then you need to look at using angular to build a component, not a full html page. Learn more. Ask Question.

Unfortunately not I kind of gave up for the moment and decided to use a normal angular slider. If possible you can let me know your application details and scenario, I will try to provide you the solution.
You can let me know here: roundsliderui. Active Oldest Votes. SteveR SteveR 6 6 silver badges 7 7 bronze badges. Thanks a lot for your great hints SteveR! Do you mean somethink like this? It is actually not working Thanks for the great hints! I am actually using the template-uibut I decided to this approach because of the round Slider, better in terms of design than the usual slider from angular.

As mentioned - you can use a change node to get at the value and put in into the msg.
Value not msg. Can someone give some examples of extracting data using the change node? An example of adding a topic with change node? Changing a topic? I can see just below but the counter value is not updating yet in Gauge. In text I see counter value updatted. In a previous reply, cymplecy showed you how to copy msg.
Perhaps you know this already, but let me repeat here as many people don't know or have forgotten it. You want to use this statement: scope.
