oke thx,
now i try to sending data message from node red to front end is work. But, if i sending data more than one for the same time this not work. can u explain this ?
Hi, can you please explain this a little more? I am not clear what you are sending more than one of? Are you sending multiple messages very quickly? Two properties in a single message?
BTW, sorry for the late reply, been rather busy this week.
yes i want to send multitape message very quickly,
because i am making project to monitoring machine, and i have more than 100 machines, and 1 machine have 2 variable time respon and time working.
I appreciate your taking the time to answer my question. It has really helped me, thank you

Thanks, I'll try and take a look later on.
oke thanks
For starters, have you checked that all of your resources are actually loading? Secondly, you are not loading the resources in the recommended order which may also have an impact.
For uibuilder v1, this is the standard set of js resources, please note that some start with / and some with ./
<!-- These MUST be in the right order. -->
<script src="/uibuilder/socket.io/socket.io.js"></script>
<script src="./uibuilderfe.min.js"></script>
<!-- --- Vendor Libraries - Load in the right order --- -->
<script src="https://cdn.jsdelivr.net/npm/lodash@4/lodash.min.js"></script>
<script src="./vendor/vue/dist/vue.js"></script>
<script src="https://unpkg.com/babel-polyfill@latest/dist/polyfill.min.js"></script>
<script src="./vendor/bootstrap-vue/dist/bootstrap-vue.js"></script>
<!-- <script src="./vendor/bootstrap-vue/dist/bootstrap-vue.min.js"></script> -->
<!-- --- Custom code goes in here --- -->
<script src="./index.js"></script>
Load your other scripts after these (except additional vendor scripts that you probably want to go before index.js), not before. Check your head as well to make sure that the css files are in the right order and all loading.
Also, are you sure you really need jQuery as well as vue? That seems rather overkill.
When I did sort that out - bearing in mind that I don't have all of your scripts - your page killed my browse completely! Haven't had a chance to work out what is going wrong. You might want to temporarily strip out all the extras and just get your timing script working with some really simple html first then we can work out what is happening.
sorry, but my page work well with jQuery.
but i'm still confused with method of .msg
can i get multiple msg.payload from node red?
uibuilder: The main global object containing the following...
* Methods:
* .onChange(attribute, callbackFn) - listen for changes to attribute and execute callback when it changes
* .get(attribute) - Get any available attribute
* .set(attribute, value) - Set any available attribute (can't overwrite internal attributes)
* .msg - Shortcut to get the latest value of msg. Equivalent to uibuilder.get('msg')
* .send(msg) - Shortcut to send a msg back to Node-RED manually
* .debug(true/false) - Turn on/off debugging
* .uiDebug(type,msg) - Utility function: Send debug msg to console (type=[log,info,warn,error,dir])
* Attributes with change events (only accessible via .get method except for msg)
* .msg - Copy of the last msg sent from Node-RED over Socket.IO
* .send - Copy of the last msg sent by us to Node-RED
* .ctrlMsg - Copy of the last control msg received by us from Node-RED (Types: ['shutdown','server connected'])
* .msgsReceived - How many standard messages have we received
* .msgsSent - How many messages have we sent
* .msgsCtrl - How many control messages have we received
* .ioConnected - Is Socket.IO connected right now? (true/false)
* Attributes without change events
* (only accessible via .get method, reload page to get changes, don't change unless you know what you are doing)
* .debug - true/false, controls debug console logging output
* ---- You are not likely to need any of these ----
* .version - check the current version of the uibuilder code
* .ioChannels - List of the channel names in use [uiBuilderControl, uiBuilderClient, uiBuilder]
* .retryMs - starting retry ms period for manual socket reconnections workaround
* .retryFactor - starting delay factor for subsequent reconnect attempts
* .ioNamespace - Get the namespace from the current URL
* .ioPath - make sure client uses Socket.IO version from the uibuilder module (using path)
* .ioTransport - ['polling', 'websocket']
You can subscribe to listen for incoming msg's.
For Vue, you do that in the mounted function in your Vue app:
uibuilder.onChange('msg', function(newVal){
console.info('[uibuilder.onChange] property msg changed!', newVal)
vueApp.msgRecvd = newVal
})
Then inside that listening function, you can check for other properties on the msg object (newVal is the new value of the msg object in the example above) if you are wanting to take different actions depending on the content of the msg received.
So you can feed in as many messages of any number of different types that you like
In addition, there is another special msg type recognised by uibuilder which is a control msg, this is differentiated by the msg.uibuilderCtrl property being set to true (see the inputHandler function in uiblib.js).
// If we receive a control message from Node-RED
uibuilder.onChange('ctrlMsg', function(newVal){
console.info('[uibuilder.onChange] property msgCtrl changed!', newVal)
vueApp.msgCtrl = newVal
})
That is used internally by uibuilder but you can also use it, as described in the WIKI, to make sure that new (or reloaded/reconnected) client connections receive some historic or initialisation data from, for example, a cache of data.
To do the same things using jQuery, you - as usual - have to wait for jQuery to be ready and then:
uibuilder.onChange('msg', function(newVal){
console.info('property msg changed!')
console.dir(newVal)
$('#showMsg').text(JSON.stringify(newVal))
//uibuilder.set('msgCopy', newVal)
})
But you really don't need both jQuery and VueJS. I would pick one or the other as it is entirely probable that they are fighting over the same parts of the DOM. If what you need to do works fine with jQuery and that is what you are familiar with, I would strip out the VueJS parts and stick with jQuery. You can add bootstrap to that.
Final part of the answer is that uibuilder.msg isn't generally accessed directly as indicated in the descriptive text. You access it via the listener which fires a function whenever the uibuilder.msg property changes as shown above. uibuilder.msg is there as a convenience in case you need the current value of the msg elsewhere in your processing, it saves you having to manually create a reference to it.
How can I extract the only payload from the full message?
Last Message Received = {
"_msgid": "e0f4f64c.d2a048",
"topic": "uibuilder",
"payload": 1571305017394
}
I don't need to show topic or _msgid. Please help on that. Thanks
write in function node after uibuilder node (msg.payload.[yourobject])
I really appreciate your replay. Can you please give me an example flow? I will be really grateful.
Thanks again.
Or you can just modify this flow:

This example flow to get spesific value object..
Open your uibuilder, click button Increment
this is uibuilder v.2.05

Please spend some time playing with Node-RED and JavaScript so that you know how to deal with the basics. There are a number of good tutorials around that don't take long to go through but will give you a good understanding of how to work with variables, objects, etc.

Thanks for your kind advice. I am really new in javascript.
I will follow your advice.
I have created a webpage using Dashboard:
it's working fine. But I just want to switch from Dashboard to uibuilder.
For this, I actually need to display some sensors value dynamically in the webpage. and also insert and retrieve data from the database.
I have tried webchocked but only one data I can send(the same problem, I don't know much about javascript).
By the way, thanks again.
