In Actionscript 3.0, how do I check if var myObject:Object is functionally identical to {}?
I take it I can't do ...
if (myObject == {}) {
// etc
}
... because Objects are reference types, right?
Check that it exists at least one field :
function isEmptyObject(myObject:Object):Boolean {
var isEmpty:Boolean=true;
for (var s:String in myObject) {
isEmpty = false;
break;
}
return isEmpty;
}
This works with dynamic object and classes, to check if an object contains fields this should be a more general solution
import flash.utils.describeType;
var test:String = "test";
var data:XML = describeType(test);
trace(data..accessor.length() > 0 || data..variable.length() > 0)

Can someone tell me why these variables marked with red are not recognized as equal (==).
Google Apps Script is Javascript-based. In Javascript, you can not compare two arrays using ==.
One method is to loop over both arrays and to check that the values are the same. For example you can include the function:
function compareArrays(array1, array2) {
for (var i = 0; i < array1.length; i++) {
if (array1[i] instanceof Array) {
if (!(array2[i] instanceof Array) || compareArrays(array1[i], array2[i]) == false) {
return false;
}
}
else if (array2[i] != array1[i]) {
return false;
}
}
return true;
}
And then update the line in your code from if (responsables == gestPor) { to if (compareArrays(responsables, gestPor)) {
For other methods of comparing arrays in Javascript, see this answer.
It is because you are comparing arrays. If you are just getting a single cell value, use getValue() instead of getValues()
To make things work, change these:
var gestPor = hojaActivador.getRange(i,13,1,1).getValues();
var responsables = hojaConMails.getRange(1,n,1,1).getValues();
to:
var gestPor = hojaActivador.getRange(i,13).getValue();
var responsables = hojaConMails.getRange(1,n).getValue();
Do these to all getValues() where you're only extracting 1 cell/value.

How can i check if two or more values in the same array are the same?
just looking for an explanation thanks
Here's a simple way to check if any value exists twice:
function hasDuplicate(array:Array):Boolean {
var keys:Dictionary = new Dictionary();
for each(var item:* in array){
if(keys[item])
return true;
keys[item] = true;
}
return false;
}
trace(hasDuplicate(["a", "b", "c"])); // false
trace(hasDuplicate(["a", "b", "c", "b"])); // true
This works by looping through all values using for each, then storing each value as a key in a Dictionary. If any value already has a key in the dictionary, it's a duplicate.
I haven't wrote on AS 3 for a couple of years but answer may looks something like this:
function hasSame(arr:Array):Boolean {
arr = arr.concat().sort();
var prev = null;
for each (var a in arr) {
if (prev != null && a == prev) {
return true;
}
prev = a;
}
return false;
}
I am using the following functions on a library and then calling them like this. The issue with the code is that I am not able return the values from the code below:
Would be great if some one suggests a way to return the value back to my test. (I will post the full working code once this is solved). I have not worked with promises so if some one can suggest a solution that be great!
Resolved this!!! check my answer:
My Testcase
iit("Should Find the OrderID and update task and submit", function () {
var job_id_data= lib.getTestData('MYPROJ_TESTCASE_001'); //Problem area
console.log(job_id_data);
element(by.xpath('//input[#type=\'search\']')).sendKeys(job_id_data);
//Do other stuff
}
The below code in my function (lib) needs to return a promise, and I don't know how to do that :(
csvConverter.on("end_parsed",function(jsonObj){
//console.log(jsonObj); //here is your result json object
var foundTestData = getObjects(jsonObj, 'TC', jobreference);
console.log(returnKeyValue ); //I can see this value
returnKeyValue = getValues(foundTestData, 'JOBID'); // I cannot return this??
});
Full Not working code ...Code
var lib = require('./lib/library.js');
iit("should go to logout page", function () {
var id_data= lib.getTestData('Test.3');
//plan to use this value in my tests
});
//Library
function getTestData(jobreference) {
//Converter Class
var Converter=require("csvtojson").core.Converter;
var fs=require("fs");
var csvFileName="C:\\TestData.csv";
var fileStream=fs.createReadStream(csvFileName);
//new converter instance
var param={};
var csvConverter=new Converter(param);
var returnKeyValue="";
var result = {};
//This requires a code change:
csvConverter.on("end_parsed",function(jsonObj){
//console.log(jsonObj); //here is your result json object
var foundTestData = getObjects(jsonObj, 'TC', jobreference);
console.log(returnKeyValue ); //I can see this value
returnKeyValue = getValues(foundTestData, 'JOBID'); // I cannot return this??
});
//read from file
fileStream.pipe(csvConverter);
return returnKeyValue;
}
function getValues(obj, key) {
var objects = [];
for (var i in obj) {
if (!obj.hasOwnProperty(i)) continue;
if (typeof obj[i] == 'object') {
objects = objects.concat(getValues(obj[i], key));
} else if (i == key) {
objects.push(obj[i]);
}
}
return objects;
}
function getObjects(obj, key, val) {
var objects = [];
for (var i in obj) {
if (!obj.hasOwnProperty(i)) continue;
if (typeof obj[i] == 'object') {
objects = objects.concat(getObjects(obj[i], key, val));
} else
//if key matches and value matches or if key matches and value is not passed (eliminating the case where key matches but passed value does not)
if (i == key && obj[i] == val || i == key && val == '') { //
objects.push(obj);
} else if (obj[i] == val && key == ''){
//only add if the object is not already in the array
if (objects.lastIndexOf(obj) == -1){
objects.push(obj);
}
}
}
return objects;
}
Managed to resolve this :) with some help from my colleague (thanks :))
This post here helped me get quickly to the point
http://know.cujojs.com/tutorials/promises/creating-promises
Solution is I updated the function to the following, which basically works with Protractor Promises. Which is great.
function getTestData(jobreference) {
var Converter=require("csvtojson").core.Converter;
var fs=require("fs");
var csvFileName="TESTJOB.csv";
var fileStream=fs.createReadStream(csvFileName);
var csvConverter=new Converter(param);
//new converter instance
var param={};
var csvConverter=new Converter(param);
var d = protractor.promise.defer();
csvConverter.on("end_parsed",function(jsonObj){
var foundTestData = getObjects(jsonObj, 'TCaseID', jobreference);
returnKeyValue = getValues(foundTestData, 'ID');
console.log(returnKeyValue.toString());
d.fulfill(returnKeyValue.toString());
});
//d.reject("fail!!!!");
fileStream.pipe(csvConverter);
return d.promise;
}
I'm tying to pass the contents of
B1L_bnt.text
to
buddy_txt.text
Can anyone tell me what am doing Wong here?
function clickHandler(event:MouseEvent):void
{
/*container_mcM.removeEventListener(MouseEvent.CLICK,clickHandler);*/
var clickedObject:DisplayObject = event.target as DisplayObject;
var bobby = Object(root).littlepicker.B1L_bnt.text;
if (clickedObject.name == 'frd_bnt1')
{
Object(root).BFFwho.buddy_txt.text = "bobby";
Object(root).gotoAndPlay(15);
}
Try this:
function clickHandler(event:MouseEvent):void
{
/*container_mcM.removeEventListener(MouseEvent.CLICK,clickHandler);*/
var clickedObject:DisplayObject = event.target as DisplayObject;
var bobby = Object(root).littlepicker.B1L_bnt.text;
if (clickedObject.name == 'frd_bnt1')
{
Object(root).BFFwho.buddy_txt.text = bobby;
Object(root).gotoAndPlay(15);
}
The issue was that you were declaring a variable named bobby. When you were trying to set the text of buddy_txtyou were setting it to a literal String 'bobby' instead of the value of the variable.
how to compare two arraycollection
collectionArray1 = ({first: 'Dave', last: 'Matthews'},...........n values
collectionArray = ({first: 'Dave', last: 'Matthews'},...........n values
how to compare..if equal just alert nochange if not alert chaged
If you just want to know if they are different from each other, meaning by length, order or individual items, you can do the following, which first checks to see if the lengths are different, then checks to see if the individual elements are different. This isn't terribly reusable, it's left as an exercise for the reader to split this apart into cleaner chunks :)
public function foo(coll1:ArrayCollection, coll2:ArrayCollection):void {
if (coll1.length == coll2.length) {
for (var i:int = 0; i < coll1.length; i++) {
if (coll1[i].first != coll2[i].first || coll1[i].last != coll2[i].last) {
Alert.show("Different");
return;
}
}
}
Alert.show("Same");
}
/* elements need to implement valueOf
public function valueOf():Object{}
*/
public static function equalsByValueOf(
first:ArrayCollection,
seconde:ArrayCollection):Boolean{
if((first==null) != (seconde==null) ){
return false;
}else if(!first && !seconde){
return false;
}
if(first.length!=seconde.length){
return false;
}
var commonLength:int = first.length;
var dictionary:Dictionary = new Dictionary();
for(var i:int=0;i<commonLength;i++){
var item1:Object = first.getItemAt(i);
var item2:Object = seconde.getItemAt(i);
dictionary[item1.valueOf()]=i;
dictionary[item2.valueOf()]=i;
}
var count:int = 0;
for (var key:Object in dictionary)
{
count++;
}
return count==commonLength;
}
/* valueOf sample
* something like javaObject.hashCode()
* use non changing fields(recommended)
*/
public function valueOf():Object{
return "_"+nonChangeField1+"_"+nonChangeField2+"...";
}
I was going to say this.
if(collectionArray === collectionArray1)
But that wont work (not triple = signs). As === is used to see classes.
I would write a function called check if object exists in array.
Create an array to hold elements that are not found. eg notFound
in Collection1 go through all the element and see if they exist in Collection2, if an element does not exist, add it to the notFound array. Use the function your created in step1
Now check Collection2, if an element is not found add it to the notFound array.
There is no 5.
Dude, use the mx.utils.ObjectUtil... the creators of actionscript have already thought about this.
ObjectUtil.compare(collection1, collection2) == 0;
