Add the element to a fresh collection of objects using an associative array

Can you help me figure out what's causing an issue when attempting to add a new element to an associative array of objects?

var storeData3 = [  
{ 'key1' : 'value1' },  
{ 'key2' : 'value2' },  
{ 'key3' : 'value3' },  
{ 'key6' : null},  
{ 'key7' : ''},  
{ 'key8' : ""},  
{ 'key9' : null},  
{ 'key10' : 'value4'}
]; //as JSON object

var i=0;

storeData3=JSON.stringify(storeData3, function(key, value)
{if(!value)
{
    i++;

};

return value;
});

JSON.parse(storeData3);

function insert(name, number) 
{
    storeData3.push({name: number});        
}

if(i>0) insert('keyX','null');

The error message reads "TypeError: storeData3.push is not a function".

Answer №1

It seems like you are trying to use the push method on the storeData3 variable, which is currently set as a string.

The following line of code

storeData3 = JSON.stringify(storeData3, function(key, value) ...

is actually converting the variable into a JSON string representation.

To fix this, you should either:

storeData3 = JSON.parse(storeData3);

or consider using a different variable altogether.

Answer №2

If you're looking to save the parsed JSON data back into variable storeData3,

JSON.parse(storeData3);

the correct way to do it is

storeData3 = JSON.parse(storeData3);

Answer №3

To successfully integrate the JSON.parse function into your code, you must include it within the array like so: 

storeData = JSON.parse(storeData3);
