I have a JSON associate array
[{"Test":"5:00pm"},{"Testing2":"4:30 pm"}]
and I want to make it so that it becomes an array where
{
theatre = Test
time = 5:00pm
},
{
theatre = Testing2
time = 4:30 pm
}
But I can't figure out how to take a key name and make it a value...
Any help? I was looking at Object.keys
but I couldn't find a suitable solution.
You have an array with object values. You'd need to loop over them:
var oldArray = [{"Test":"5:00pm"},{"Testing2":"4:30 pm"}];
var newArray = [];
for (var i = 0; i < oldArray.length; i++) {
var keys = Object.keys(oldArray[i]);
newArray.push({
theatre: keys[0],
time: oldArray[i][keys[0]]
});
}
This will give you an array stored in newArray
with two elements. The first element is an object with kvps theatre: 'Test'
and time: '5:00pm'
. The second element is an object with kvps theatre: 'Testing2'
and time: '4:30pm'
.
Try this workaround:
var json = '[{"Test":"5:00pm"},{"Testing2":"4:30 pm"}]';
var betterJson = json.replace('{"', '{"theatre":"').replace('":"','",time:"');
If the JSON is always as simple as above, then this should work. But it's brittle...
If you have a JS object, you could use Object.keys . That will work in the latest browsers.
You can also loop each item and just save the 1st item.
var result = [];
var str = [{"Test":"5:00pm"},{"Testing2":"4:30 pm"}];
for (var i = 0; i < str.length; i++) {
var obj = {};
foreach (var key in str[i]) {
obj.theatre = key;
obj.time = str[i][key];
}
result.push(obj);
}
May be a bit clunky, BUT should work cross-browser.
var js = [{"Test":"5:00pm"},{"Testing2":"4:30 pm"}]
var newJSON = []
for(var i = 0; i< js.length; i++) {
for( var key in js[i]) {
if(js[i].hasOwnProperty(key)) {
var tmpJS= {};
tmpJS['theater'] = key;
tmpJS['time'] = js[i][key];
newJSON.push(tmpJS);
}
}
}
