I have an array full of values, myArray[]
I'm trying place this array in a hash table to pass over the socket from my node.js server.
I want the array in the hash table to contain all the same information as myArray.
var item = [
{ hashArray: [] }
];
for (var i = 0; i < myArray.length; i++) {
item.hashArray.push(myArray[i]);
}
I receive the error that I can't call push of undefined.
Thanks for any help!
EDIT: Thanks very much everyone, I see what I was doing wrong!
You're creating item as an array with an object on the zero'th index:
var item = [
{ hashArray: [] }
];
Either let item be the object:
var item = {
hashArray: []
};
I assume this to be what you want, unless item is meant to be an array, in which case you should push() to item[0]:
item[0].hashArray.push(myArray[i]);
EDIT
On a side-note, why not just let the hashArray array hold the values from myArray?
var item = {
hashArray: myArray
};
(Asking out of curiosity here :) )
you wraped the object containing hashArray in an array. To access the field hashArray you have to do the following:
item[0].hashArray.push(...)
item[0].hashArray.push(myArray[i]);
or
var item = { hashArray: [] };
