Populate new feature attribute table, sequential numbering

williamcarr — Wed, 30 Apr 2014 10:59:12 GMT

I am attempting to add sequential numbering to newly added graphics, but I'm a little lost on logic. Would this be possible with an i = i + 1 loop? Basically I need to populate an attribute field of a feature layer with a prefix and a number (J1, J2, J3 ect.)

That should work. Increment i for every graphic you create using i++; or i=i+1; and then set your attribute to 'J' + i;

              var i= i + 1;
  var attr = {"cycle":"J"+ i};
           
           
featureLayer.applyEdits([graphic], null, attr);
          console.log(" Fire on everything!");

I've been playing around with this, but it's not inputting the value. Is that even set up right? It will add the point, but no attributes.

I'm not familiar with the the applyEdit's method of the FeatureLayer but i have used something like this to add attributes to a new graphic.

var attr= {"cycle": "J" + 1};

var graphic= new Graphic(geometry, symbol, attr, infoTemplate);

I got it to add the variable (when I changed it to a stationary number), but it's not adding the sequence.

  var geometry;
       function addGraphic(pt){
          var symbol = new SimpleMarkerSymbol(
            SimpleMarkerSymbol.STYLE_CIRCLE, 
            12);
          graphic = new Graphic(pt, symbol,attr);
          map.graphics.add(graphic);
          
             var i ;
              var attr = {};
          attr["asdf"] ="J"+ i + 1;
             
             
          
          new esri.geometry.Point(pt, map.spatialReference);
          
          var newFeature = new esri.Graphic(geometry, null,null);
           
           graphic.setAttributes(attr);
   
           
           
featureLayer.applyEdits([graphic], null, null);
          console.log(" Fire on everything!");

Any thoughts?

How about this

 var i = 0;        function addGraphic(pt) {            console.log("addingGraphic");            i++;            var symbol = new SimpleMarkerSymbol( SimpleMarkerSymbol.STYLE_CIRCLE,12);             var template = new InfoTemplate("results", "${*}");                           var attr = {};            attr["asdf"] = "J" + i;             var graphic = new Graphic(pt, symbol, attr,template);            map.graphics.add(graphic);                                 //featureLayer.applyEdits([graphic], null, null);            //console.log(" Fire on everything!");        }

That got it!!!

Thanks for all your help!

 var i = 0;
        var geometry;
       function addGraphic(pt){
          var symbol = new SimpleMarkerSymbol(
            SimpleMarkerSymbol.STYLE_CIRCLE, 
            12);
            i++;
          graphic = new Graphic(pt, symbol,attr);
          map.graphics.add(graphic);
          
             
              var attr = {};
          attr["asdf"] = i;
             
             
          
          new esri.geometry.Point(pt, map.spatialReference);
          
          var newFeature = new esri.Graphic(geometry, null,null);
           
           graphic.setAttributes(attr);
   
           
           
featureLayer.applyEdits([graphic], null, null);
          console.log(" Fire on everything!");
