needing some advice on how to do this properly recursively.
Basically what I'm doing, is entering in a bunch of text and it returns it as JSON.
For example:
The text:
q
b
name:rawr
Returns:
[
"q",
"b",
{
"name": "rawr"
}
]
And the following input:
q
b
name:rawr:awesome
Would return (output format is not important):
[
"q",
"b",
{
"name": {
"rawr": "awesome"
}
}
]
How can I modify the following code to allow a recursive way to have objects in objects.
var jsonify = function(input){
var listItems = input, myArray = [], end = [], i, item;
var items = listItems.split('\r\n');
// Loop through all the items
for(i = 0; i < items.length; i++){
item = items[i].split(':');
// If there is a value, then split it to create an object
if(item[1] !== undefined){
var obj = {};
obj[item[0]] = item[1];
end.push(obj);
}
else{
end.push(item[0]);
}
}
// return the results
return end;
};
I don't think recursion is the right approach here, a loop could do that as well:
var itemparts = items[i].split(':');
var value = itemparts.pop();
while (itemparts.length) {
var obj = {};
obj[itemparts.pop()] = value;
value = obj;
}
end.push(value);
Of course, as recursion and loops have equivalent might, you can do the same with a recursive function:
function recurse(parts) {
if (parts.length == 1)
return parts[0];
// else
var obj = {};
obj[parts.shift()] = recurse(parts);
return obj;
}
end.push(recurse(items[i].split(':')));
Here is a solution with recursion:
var data = [];
function createJSON(input) {
var rows = input.split("\n");
for(var i = 0; i < rows.length; i++) {
data.push(createObject(rows[i].split(":")));
}
}
function createObject(array) {
if(array.length === 1) {
return array[0];
} else {
var obj = {};
obj[array[0]] = createObject(array.splice(1));
return obj;
}
}
createJSON("p\nq\nname:rawr:awesome");
console.log(data);
