Question

I have an array

 var topics = [];

I have a list of numbers 1-10

var obj = {one:1, two:2, three:3, four:4, five:5, six:6, seven:7, eight:8, nine:9, ten:10};

I just want to push the number into the array but not sure what to call it in the push function?:

$.each(obj, function(i, val) { 
    topics.push({
        count: val
    });
    console.log(val);
});

Answer 1

If your intention is for the final array to look like this:

[ 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 ]

Then within your existing function you just need to say:

topics.push(val);

If your intention is for the final array to look like this:

[ "one", "two", "three", "four" /* etc */ ]

Then within your existing function you just need to say:

topics.push(i);

If your intention is for the final array to look like this:

[ { one : 1 }, { two : 2 }, { three : 3 } /* and so forth */ ]

Then you would do it like this:

$.each(obj, function(i, val) {
   var item = {};
   item[i] = val;
   topics.push(item);
   console.log(val);
});

You can’t just say:

topics.push( { i : val } );

Because JS object literal syntax doesn’t allow use of variables for the property names (keys) though it does allow variables for the property values, so { i : val } creates an object with one property called “i”.

In your code, if count is a variable you would use it like I showed above, i.e.,:

item[count] = val;

If “count” is the actual string that you want the property to be called then your code will work as is.
