Re: How to get a group of units through javascript SDK?

Denisse, to get all unit groups You have access to - just try to use:

wialon.core.Session.getInstance().getItems("avl_unit_group")

or

wialon.core.Session.getInstance().searchItems({itemsType:"avl_unit_group",propName:"",propValueMask:"",sortType:""}, 1, 0xFFFFFFFF, 0, 0xFFFFFFFF, function() {console.log(arguments);});

if You want to get unit groups of some specific account use such request:

wialon.core.Session.getInstance().searchItems({itemsType:"avl_unit_group",propName:"sys_billing_account_guid",propValueMask:"X",sortType:""}, 1, 0xFFFFFFFF, 0, 0xFFFFFFFF, function() {console.log(arguments);});

replace X with account id You are interested in

Re: How to get a group of units through javascript SDK?

Denisse, to get units of each group that belong to some account You can do the following:

wialon.core.Session.getInstance().searchItems({itemsType:"avl_unit_group",propName:"sys_billing_account_guid",propValueMask:"X",sortType:""}, 1, 0xFFFFFFFF, 0, 0xFFFFFFFF, function(code, data) {
     if (code || !data || !data.items)
          return;
     var units = [];
     for (var i = 0; i < data.items.length; i++) {
          var group = data.items[i];
          var groupUnits = group.getUnits();
          for (var j = 0; j < groupUnits.length; j++) {
               units.push(groupUnits[j]);
          }
     }
     console.log(units);
     if (units.length)
          wialon.core.Session.getInstance().searchItems({itemsType:"avl_unit",propName:"sys_id",propValueMask:units.join(","),sortType:""}, 1, 0xFFFFFFFF, 0, 0xFFFFFFFF, function() {console.log(arguments);});
});

Hi deal good day,

The detail of my query is that I am getting the units that belong to a group but wanting to get their position or names I can not. I put the code that modifies according to Playground. Some suggest or idea please, I will be very important, thanks

// Print message to log
function msg(text) { $("#log").prepend(text + "<br/>"); }

Re: How to get a group of units through javascript SDK?

Denisse, you don't get units because only unit_groups were added to session.
Just add units to updateDataFlags:

[{type: "type", data: "avl_unit_group", flags: flags, mode: 0}, {type: "type", data: "avl_unit", flags: flags, mode: 0}]

Add lastPosition data flag: wialon.item.Unit.dataFlag.lastPosition

Also change code of getting units' positions:

    msg(unidades.length);
    for(var j=0;j<inidades.length;j++){
       var u = wialon.core.Session.getInstance().getItem(inidades[j]);
       msg(u.getPosition()); //THIS PROBLEM NO INFORMATION
    }

Re: How to get a group of units through javascript SDK?

mshamsan hello,
You can try to use search items by properties request. This request allows to get internal IDs of the items and other properties. You can use it to get all available unit groups names and IDs and array of units' IDs included in each group.
Example of the request: https://hst-api.wialon.com/wialon/ajax.html?svc=core/search_items&params={"spec":{"itemsType":"avl_unit_group","propName":"sys_name","propValueMask":"*","sortType":"sys_name"},"force":1,"flags":1,"from":0,"to":0}&sid=ACTIVE_SID

The units IDs will be available in the "u" parameter array.
Then you can use IDs of the units t search specific unit details with search item by ID request.
