I have a queryFeatures on a featureLayer that is based on mutiple objectIds. I need to iterate through each feature and store attributes in an array. I need to keep each feature's array in another array (or maybe an object?) so I can have it as input to my chart.
gQuery = new Query();
gQuery.objectIds = idList; //defined earlier
seriesList.length = 0; //declared earlier as seriesList = [];
featureLayer.queryFeatures(gQuery, function(results) {
arrayUtils.forEach(results.features, function (result){
var list = createRateList(result);
console.log("list is " + list);
seriesList.push({data: list});
});
});
function createRateList(results){
var atts = results.attributes;
var county = atts.County;
rateList.length = 0;
reverseRateFields.length = 0;
//gets the rate values for selected county for all years, list of field defined earlier
arrayUtils.forEach(reverseRateFields, function (field){
rateList.push(atts[field]);
});
return rateList;
}
At the point I have do a console.log on list, it contains the values I expect. I add it to my seriesList and it still looked OK. Going to the next feature, I the console.log display what I expect from the list, but what I push to seriesList affects what's already in there. Examining the contents of seriesList shows the initial item [0] with content I just added from the 2nd time through. This continues through how ever many features I had from queryFeatures until I have a seriesList full of the exact same list of values, which are from the final feature.
I don't know if I have a looping problem, or don't understand the nature of array variables.
