Change point value via script

[James]

I'm trying to create a button which is when button clicked it will set multiple point values. I look for relevant question in this forum, unfortunately it doesnt work for me. Any help is very appreciated. Here is my code.

 <a id="476838d4-4ac0-4562-84c8-787a0f341fc1" style="position: absolute; left: 806px; top: 86px; width: 221.266px; height: 44.9063px; z-index: 3; color: rgba(255,56,47);" href="#" onclick="call_this()">Occupied</a>
     
    <script type="text/javascript">
       function call_this()
       {
           var tags = com.serotonin.m2m2.db.dao.DataPointTagsDao.instance.getTagsForDataPointId( p.getDataPointWrapper().getId() );
           var newTags = {"tags.TmpSpvCoSpvClg":"20"};
                CONTEXT_POINTS.p.getVO().setTags(newTags); 
                com.serotonin.m2m2.db.dao.DataPointDao.instance.saveDataPoint(CONTEXT_POINTS.p.getVO());
            
       
       }

If you're trying to do this from the dashboard it's not gonna work;
Scripts have to be executed within an angularJS controller;
The best thing by far you can do is to use the ma-get-point-value component.
I'm making three assumptions here:

1. You know which points you want to alter
   2)These points will not change - ie this page is static and does not need further amendments regarding the points you wish to set.
   3)You are using mango version 3 with the mangoUI dashboards

<!--  1 get the points xid value and use it in the ma-get-point-value -->

<ma-get-point-value point-xid="DP_myPointXID" point="point1"></ma-get-point-value>
<ma-get-point-value point-xid="DP_my2ndPointXID" point="point2"></ma-get-point-value>

You can find the point xid via the [mango domain]/data_sources.shtm page:

2)next: get your ma-button directive and use angular's ng-click event to set the points.
This is a bit crude but if you have little or no programming experience it's certainly one way of doing what you desire.

<ma-button label="Set Points" tooltip="Sets these points to '1'" raised="true" hue="hue-2" palette="primary" ng-click="point1.setValue('1'); point2.setValue('1');"></ma-button>

Together it looks like this:

<!--  1 get the points xid value and use it in the ma-get-point-value -->

<ma-get-point-value point-xid="DP_myPointXID" point="point1"></ma-get-point-value>
<ma-get-point-value point-xid="DP_my2ndPointXID" point="point2"></ma-get-point-value>
<!-- 2 add button with angular on click event -->
<ma-button label="Set Points" tooltip="Sets these points to '1'" raised="true" hue="hue-2" palette="primary" ng-click="point1.setValue('1'); point2.setValue('1');"></ma-button>

Good Luck

Hi James,

It looks to me like you're changing tags, not values. You could do this through the /rest/v2/data-points API or the /rest/v2/script/run endpoint if you were wanting to use a script. You do not need to preface the tag with tags. and you should go through the DataPointWrapper to ensure the tags are loaded, so currently you'd reference it like p.getDataPointWrapper().tags["tags.TmpSpvCoSpvClg"] which is probably not ideal. You can explore the API using swagger if it's enabled in your env.properties file at startup on the /swagger-ui.html page.

Thanks Fox for the samples if indeed he does mean point values!

NP, although looking at what you've stated, I've missed the mark completely... I thought he was trying to do a dashboard page, unless you're telling me the com library is in the dashboard too....

In your defense he did say,

I'm trying to create a button which is when button clicked it will set multiple point values.

But CONTEXT_POINTS and com.serotonin are definitely not features in dashboards, and exist in Mango JavaScript environments on the server side.

@mattfox can we add a delay after button is pushed?
For example,
1/ before clocking the button, the value 2 points are 0 and 0.
2/ after clocking the button, value of 2 points are 1 and 0. They keep this value in 2 seconds
3/ after 2 seconds, value of 2 points are 0 and 0.

[MattFox]

@tungthanh500 if you're using an angularjs controller, yes.

Otherwise you can use it to trigger a meta data point or scripting data source and use RuntimeManager.sleep(2000);
Between each data point supplied in the context to be changed to the desired values after each delay.
