I know this questions exists like 100 times, but I just can't transfer the solutions to my code, so I hope you can help me. This should be pretty easy but I just don't get it working.
This is just my code with other variable because of reasons:
My Code:
for (var key in array) {
}
The JSON I want:
[{
key: "One",
y: 5
}, {
key: "Two",
y: 2
},];
Pseudo JSON:
[{
key: key,
y: array[key].data
},{
key: key,
y: array[key].data;
},];
You can try this solution:
var data = [];
for (var key in array) {
data.push({
key : key,
y : array[key].data
});
}
console.log(data);
But, what about Pseudo JSON:?
DEMO - See console (chrome) for output
I don't understand what is 'array'. Is it an object or an array?
I think what you want might be this, if 'array' is an array:
var new_arr = [];
your_array.forEach( function(entry) {
new_arr.push({key: entry, y: entry.data}); // you should change it according to your need.
})
return JSON.stringify(new_arr);
Or if 'array' is just an object, you may need this:
var new_arr = [];
for (key in array) {
new_arr.push({key: key, y: array[key].data}); // you should change it according to your need.
}
return JSON.stringify(new_arr);
JSON is just a syntax for expressing objects and arrays independently of a scripting language's syntax.
Apparently you want to convert your array into another structure and have this expressed in JSON. The conversion to JSON is usually performed by the built-in function JSON.stringify.
Assuming your array isn't really an array (which has only numeric indices, usually without gaps), but more an object-like structure, I'd suggest the following code:
var data = []
for (var key in array)
{
data.push({key: key, y: array[key].data});
}
var json = JSON.stringify(data);
//...
If array really was an array you shouldn't use a for-in-loop. Otherwise you should consider renaming it to avoid confusion.
you can use following line to create an array of json
var jsonArr = [];
then you can create json object from following line
var obj = new Object();
put data in json object as following
obj['id'] = 123;
obj['name'] = 'ABC';
then put json object in json array as
jsonArr.push(obj);
you want to add multiple objects in json array then simply create json object and add one by one using push method.
[{"id":"123","name":"ABC"}]
