push Object in array in $.each

Maybe I'm just blind, but I'm struggling for a good amount of time now:
I have a small piece of JS-Code here:
var linkInput = $('#Link input.gwt-TextBox').val();
var parentRow = $('#Link').parent().parent();
var links = linkInput.split("|");
// hide text-input
$(parentRow).hide();
// get rid of empty elements
links = links.filter(Boolean);
var aSites = [];
var oSite = {};
$(links).each(function (k, v) {
splits = v.split(".");
domainName = splits[1];
oSite.name = domainName;
oSite.url = v;
aSites.push(oSite);
});
console.log(aSites);
To specify: Get the value of an input-field, hide the row afterwards and save all the values in an object, which is then pushed into an array.
The parameter, taken from the console-tab of google Chrome:
var links = ["www.myshop1.de/article/1021581", "https://www.myshop2.de/article/1021581"] [type: object]
I thought, I iterate through all elements of this object (in that case 2 times), push the values into an object and the object into an array, to have access to all of them afterwards.
At some point however, I seem to override my former values, since my output looks like this:
0: {name: "myshop1", url: "https://www.myshop1.de/1021581"}
1: {name: "myshop2", url: "https://www.myshop2.de/1021581"}
length: 2
__proto__: Array(0)
Where is my mistake here? Is there a smarter way to realize this?
On a sidenote:
I tried to use only an array (without adding an object), but it seems like I
can't use an associative key like this:
var myKey = "foo";
var myValue = "bar";
myArray[myKey] = myValue

You should move this:
var oSite = {};
...inside the each callback below it, because you need a new object in each iteration.
Otherwise you are mutating the same object again and again, pushing the same object repeatedly to the aSites array, which ends up with multiple references to the same object.
Not related, but you can use $.map to create your array (or vanilla JS links.map()):
var aSites = $.map(links, function(v) {
return { name: v.split(".")[1], url: v };
});

Count the recurrence of a word

I am writing a function called "countWords".
Given a string, "countWords" returns an object where each key is a word in the given string, with its value being how many times that word appeared in th given string.
Notes:
* If given an empty string, it should return an empty object.
function countWords(str) {
var obj = {};
var split = str.split(" ");
return split;
}
var output = countWords('ask a bunch get a bunch');
console.log(output); // --> MUST RETURN {ask: 1, a: 2, bunch: 2, get: 1}
Have any idea?

I wont give you finished code ( thats not the sense of a homework) , but i try to get you to solve the problem on your own.
So far you've already got an array of words.
Next lets declare an object we can assign the properties later.
Then we'll iterate over our array and if the array element doesnt exist in our object as key yet ( if(!obj[array[i]])) well create a new property, with elements name and the value 1.( obj[array[i]=1; )
If the element is a key of that object, lets increase its value.
( obj[array[i]]++;)
Then return the object.

So you could use a javascript Map for this like so:
var myMap = new Map();
myMap.set(keyString, count);
and access the value of the key like so:
myMap.get(keyString);

Access value from JavaScript object via array-string

my problem is that i have a json-object with and array into here an example.
var object = {
'items':['entry1','entry2']
}
I want to access 'entry2' over a constant string that I receive and shouldn't be changed.
var string = 'items[1]';
The only way I'm solving this problem is over the eval function...
eval('object.'+string);
This returns me entry2.
Is there any other way to achieve this without using eval()?
Like object[string] or object.string

Supposing your string is always the same form, you could extract its parts using a regex :
var m = string.match(/(\w+)\[(\d+)\]/);
var item = object[m[1]][+m[2]];
Explanation :
The regex builds two groups :
(\w+) : a string
\[(\d+)\] : some digits between brackets
and those groups are at index 1 and 2 of the array returned by match.
+something parses the number. It's not strictly needed here as the array accepts a string if it can be converted but I find the code more readable when this conversion is explicited.

On top of dystroy's anwser, you can use this function:
function getValueFromObject(object, key) {
var m = key.match(/(\w+)\[(\d+)\]/);
return object[m[1]][+m[2]];
}
Example:
var object = {
'items':['entry1','entry2']
}
var string = 'items[1]';
var value = getValueFromObject(object, string); //=> "entry2"

First, you can get the array from inside:
var entries = object.items // entries now is ['entry1','entry2']
Then you need to index that to get the second item (in position 1). So you achieve what you want with:
var answer = entries[1] // answer is now 'entry2'
Of course, you can combine this to get both done in one step:
var answer = object.items[1] // answer is now 'entry2'
... I can see this is a contrived example, but please don't call your Objects 'object', or your Strings 'string' :s

try something like this
object.items[1];

Jquery fill object like array

This should be pretty easy but I'm a little confused here. I want to fill this object:
var obj = { 2:some1, 14:some2, three:some3, XX:some4, five:some5 };
but in the start I have this:
var obj = {};
I´m making a for but I don't know how to add, I was using push(), but is not working. Any help?

You can't .push() into a javascript OBJECT, since it uses custom keys instead of index. The way of doing this is pretty much like this:
var obj = {};
for (var k = 0; k<10; k++) {
obj['customkey'+k] = 'some'+k;
}
This would return:
obj {
customkey0 : 'some0',
customkey1 : 'some1',
customkey2 : 'some2',
...
}
Keep in mind, an array: ['some1','some2'] is basicly like and object:
{
0 : 'some1',
1 : 'some2'
}
Where an object replaces the "index" (0,1,etc) by a STRING key.
Hope this helps.

push() is for use in arrays, but you're creating a object.
You can add properties to an object in a few different ways:
obj.one = some1;
or
obj['one'] = some1;

I would write a simple function like this:
function pushVal(obj, value) {
var index = Object.size(obj);
//index is modified to be a string.
obj[index] = value;
}
Then in your code, when you want to add values to an object you can simply call:
for(var i=0; i<someArray.length; i++) {
pushVal(obj, someArray[i]);
}
For info on the size function I used, see here. Note, it is possible to use the index from the for loop, however, if you wanted to add multiple arrays to this one object, my method prevents conflicting indices.
EDIT
Seeing that you changed your keys in your questions example, in order to create the object, you can use the following:
function pushVal(obj, value, key) {
//index is modified to be a string.
obj[key] = value;
}
or
obj[key] = value;
I'm not sure how you determine your key value, so without that information, I can't write a solution to recreate the object, (as is, they appear random).

Jquery function consumes the array

I don't quite understand what's wrong with my function that I wrote,
When I pass an array to it, eg:
var pvars=['health/1/1.jpg','health/1/2.jpg','health/1/3.jpg','health/1/4.jpg'];
cache_threads(pvars,1);
Then I end up with an empty variable, eg:
alert(pvars);
Returns an empty string.
Here is my function:
var cache_threads=function (arruy,quant){
if (quant==undefined) quant=1;
var div=Math.ceil(arruy.length/quant);
var a = arruy;
while(a.length) {
cache_bunch(a.splice(0,div));
}
}

a and arruy are the same array.
When you .splice one, you'll be splicing the other one, too!
If you want a (shallow) copy of the array, use .slice():
var a = arruy.slice(0);
