I have a list of object and I want populate the list with another dynamic list using for each , so when I try to do so only the last value from the dynamic list is added to the other list..
some one please help
var keylist =[1,2] ;
for (var key in keylist) {
_devchanged=[
Employeemodal(
developer: key
)
];
}
You can use .add like this
var keylist =[1,2] ;
List<Employeemodal> _devchanged = [];
for (var key in keylist) {
_devchanged.add(Employeemodal(developer: key));
}

Im trying to get property from oData return model. I set data in success callback function from oData to JSON model.
oODataModel.read("/ConnObjSet?$filter=Objecttype eq 'CONNOBJ' and ConnObject eq '20000000002'",
true,
true,
false,
function _OnSuccess(oData, oResponse){
var oJSON = new sap.ui.model.json.JSONModel();
oJSON.setData(oData);
sap.ui.getCore().setModel(oJSON, "ConnectionObject");
},
This is my JSON object in console log and highlighted property I want to get. I want to get every 15 Buspartner number from whole array.
And this is what I tried to get property:
var oLog = sap.ui.getCore().getModel("ConnectionObject").oData.results;
console.log(oLog);
If you have an array of objects, you can get an array of properties from each of these objects by using the Array.map() function.
So in your case:
var aResults = this.getView().getModel().getProperty("/results");
var aBuspartner = aResults.map(function (r) { return r.Buspartner});
var oJSONModel = new sap.ui.model.json.JSONModel();
oJSONModel.setProperty("/resultarray", aBuspartner)
Please try:
var aResults = this.getView().getModel().getProperty("/results");
var oJSONModel = new sap.ui.model.json.JSONModel();
oJSONModel.setProperty("/resultarray",new Array())
for(var i = 0; i<aResults.lenght;i++){
oJSONModel.getProperty("/resultarray").push(aResults[i].Buspartner)
}
You could also try to add a filter and select to your oData.read
The oData-URL
http://services.odata.org/V2/Northwind/Northwind.svc/Products
selects all Product with all their properties
http://services.odata.org/V2/Northwind/Northwind.svc/Products?$filter=UnitsInStock%20eq%2017
shows only Products with "UnitsInStock=17"
http://services.odata.org/V2/Northwind/Northwind.svc/Products?$select=ProductID&$filter=UnitsInStock%20eq%2017
selects only the ProductID of Products with "UnitsInStock=17"
so
oODataModel.read("/ConnObjSet?$select=Buspartner&$filter=Objecttype eq 'CONNOBJ' and ConnObject eq '20000000002'"
...
should get the filtered Buspartners directly.
I am receiving the JSON object as a list of objects:
result=[{"key1":"value1","key2":"value2"}]
I am trying to retrieve the values from this list in Node.js. I used JSON.stringify(result) but failed. I have been trying to iterate the list using for(var key in result) with no luck, as it prints each item as a key.
Is anyone facing a similar issue or has been through this? Please point me in the right direction.
If your result is a string then:
var obj = JSON.parse(result);
var keys = Object.keys(obj);
for (var i = 0; i < keys.length; i++) {
console.log(obj[keys[i]]);
}
Lookslike you are pointing to wrong object.
Either do like
var result = [{"key1":"value1","key2":"value2"}];
for(var key in result[0]){ alert(key);}
or
var keys = Object.keys([{"key1":"value1","key2":"value2"}][0]);
alert(keys);
Okay, assuming that result here is a string, the first thing you need to do is to convert (deserialize) it to a JavaScript object. A great way of doing this would be:
array = JSON.parse(result)
Next you loop through each item in the array, and for each item, you can loop through the keys like so:
for(var idx in array) {
var item = array[idx];
for(var key in item) {
var value = item[key];
}
}
Wouldn't this just be:
let obj = JSON.parse(result);
let arrValues = Object.values(obj);
which would give you an array of just the values to iterate over.
A little different approach:
let result=[{"key1":"value1","key2":"value2"}]
for(let i of result){
console.log("i is: ",i)
console.log("key is: ",Object.keys(i));
console.log("value is: ",Object.keys(i).map(key => i[key])) // Object.values can be used as well in newer versions.
}
try this code:
For result=[{"key1":"value1","key2":"value2"}]
Below will print the values for Individual Keys:
console.log(result[0].key1)
console.log(result[0].key2)
This is for JsonObject (not JsonArray per se). p is your jsonobject the key pairs are key and p[key]
var p = {
"p1": "value1",
"p2": "value2",
"p3": "value3"
};
for (var key in p) {
if (p.hasOwnProperty(key)) {
console.log(key + " -> " + p[key]);
}
}
How to get the key at specified index of a object in Flex?
var screenWindowListObject:Object = {
'something' : 'awesome',
'evenmore' : 'crazy',
'evenless' : 'foolish'
};
I want key at index 1 i.e evenmore.
In JavaScript it can be possible by using the following code.
var keys = Object.keys(screenWindowListObject);
console.log(keys[1]); // gives output 'evenmore'
Is there any equivalent in Flex?
I have an object with unique keys. Values are not unique. I am displaying the values in DropDownList by adding them to an Array Collection. I have to get the key from the Object based on the selected index.
According to Adobe, "Object properties are not kept in any particular order, so properties may appear in a seemingly random order." Because of this, you'll have to invent your own order. This can be achieved by populating an array with your keys, and then sorting that.
function getKeyOrder(hash:Object, sortType:int = 3):Array {
// Returns an array with sorted key values.
/*
1 = CASEINSENSITIVE
2 = DESCENDING
3 = ASCENDING
4 = UNIQUESORT
8 = RETURNINDEXEDARRAY
16 = Array.NUMERIC
*/
var order:Array = [];
for (var k:String in hash) {
order.push(k);
}
var reverse:Boolean = false;
if (sortType == 3) {
reverse = true;
sortType = 2;
}
order.sort(sortType)
if (reverse) { order.reverse(); }
return order;
}
var screenWindowListObject:Object = {
'something' : 'awesome',
'evenmore' : 'crazy',
'evenless' : 'foolish'
};
var orderedKeys:Array = getKeyOrder(screenWindowListObject);
for each (var key in orderedKeys) {
trace(key + ":" + screenWindowListObject[key]);
}
/* Results in...
evenless:foolish
evenmore:crazy
something:awesome
*/
trace("Index 0 = " + screenWindowListObject[orderedKeys[0]])
// Index 0 = foolish
getKeyOrder() returns an array with your keys in ascending order by default. This way, you'll be guaranteed to always have the same sequence of keys, and be able to pull up the index you're looking for. Just be wary when adding more keys, as it will shift each entry depending on where it shows up in the sort.
JavaScript's Object.keys uses the same order as a for..in loop, so in AS3 you could implement it the same way:
function getKeys(object:Object):Array {
var keys:Array = [];
for(var key in object){
keys.push(key);
}
return keys;
}
Note, though, that the enumerable order of keys on an object at runtime is not necessarily the same as you've written it in code.
I just want to change all the keys in batchesX. But I can't seem to alter all keys, because of concat. This is what I learned from post.
Please advise how I can change all keys with numbers.
var batchesX = '[{"batch":"0010002033"},{"batch":"0010001917"},{"batch":"0000020026"},{"batch":"0000017734"},'+
'{"batch":"0000015376"},{"batch":"0000014442"},{"batch":"0000014434"},{"batch":"0000014426"},'+
'{"batch":"0000013280"},{"batch":"0000012078"},{"batch":"0000012075"},{"batch":"0000012072"},'+
'{"batch":"0000011530"},{"batch":"0000011527"},{"batch":"0000011342"},{"batch":"0000010989"},'+
'{"batch":"0000010477"},{"batch":"0000008097"},{"batch":"0000007474"},{"batch":"0000006989"},'+
'{"batch":"0000004801"},{"batch":"0000003566"},{"batch":"0000003565"},{"batch":"0000001392"},'+
'{"batch":"0000001391"},{"batch":"0000000356"},{"batch":"0000"},{"batch":"000"},{"batch":""},'+
'{"batch":null}]'; // 30 elements
//in JSON text
var batchi = "batch";
var obj_batchesY = JSON.parse(batchesX);
console.debug(obj_batchesY);
var obj_batchesYlength = obj_batchesY.length;
console.debug(obj_batchesYlength);
var obj_batchesX = JSON.parse(batchesX,
function(k,v)
{
for(var i=1; i <= obj_batchesYlength; i++ )
{
if(k=="batch")
{
this.batchi.concat(string(i)) = v;
}
else
return v;
}
}
);
console.debug(obj_batchesX);
Is the code too long winded?
Many thanks in advance.

The return value of the reviver function only replaces values. If you need to replace keys, then use stringify and replace before the parse call, like this:
JSON.parse(JSON.stringify({"alpha":"zulu"}).replace('"alpha":','"omega":'))
Here is how to replace all numeric keys:
function newkey()
{
return Number(Math.random() * 100).toPrecision(2) + RegExp.$1
}
//Stringify JSON
var foo = JSON.stringify({"123":"ashanga", "12":"bantu"});
//Replace each key with a random number without replacing the ": delimiter
var bar = foo.replace(/\d+("?:)/g, newkey)
//Parse resulting string
var baz = JSON.parse(bar);
Make sure each replaced key is unique, since duplicate keys will be removed by the parse method.
I'm looking to get/display the key name of an object in AS3.
I have for example :
var obj:Object = {key:"value"};
Here I try to display "key" (not its value).
The goal is to be able to merge two objects together.
Any idea ?
Thanks !
To get at the keys of an object you need to loop over them:
for (var key:String in obj) {
trace("key:", key, "value:", obj[key]);
}
Thus, merging obj1 and obj2 (with anything from the second overwriting the first) would look like this:
var merged:Object = {};
var key:String = "";
for (key in obj1) {
merged[key] = obj1[key];
}
for (key in obj2) {
merged[key] = obj2[key];
}
