I have this JSON Object
{1: "test projekt", 4: "Second Project",
5: "Third Project", 6: "Fourth Project",
7: "5th one", 8: "6th one dude",
uhash: "7021a11332508b6e30d3b6d3e95180398228b0e4010fc3f05db81e80"}
i want to split it into:
{1: "test projekt", 4: "Second Project",
5: "Third Project", 6: "Fourth Project",
7: "5th one", 8: "6th one dude"}
and
{uhash: "7021a11332508b6e30d3b6d3e95180398228b0e4010fc3f05db81e80"}
how can I do it in js?
The easiest way to manipulate JSON is to parse it into objects, manipulate the objects and then create JSON from the objects:
var o = JSON.parse(json);
var o2 = { uhash: o.uhash };
delete o.uhash;
var json1 = JSON.stringify(o);
var json2 = JSON.stringify(o2);
Note: The JSON object is not supported in older browers, e.g. IE 7.
something like this ?
var secondObj = {uhash: firstObj.uhash};
delete firstObj.uhash;
for something more complex you can use underscore : underscorejs. take a look at groupBy or map. depends on what exactly do you need.
The for ... in loop will iterate over object keys. Be sure to limit it using the hasOwnProperty method otherwise for ... in will find all inherited keys of the object. Once you can iterate over the object, all you need to do is check the keys and populate two other objects.
var numbers = {},
uhash = {},
prop = '';
for (prop in json) {
if (json.hasOwnProperty(prop)) {
if (!isNaN(prop)) {
numbers[prop] = json[prop];
} else {
uhash[prop] = json[prop];
}
}
}
This might help
function popAttributeFromData (attrs, data) {
for (var key in data) {
if(key === attrs) {
var result = {
attrs: data[attrs]
};
delete data[attrs];
return result;
}
}
return null;
}
What it does it iterating through the keys from data until the key matches with the passed parameter attrs.
Here is the result
