Javascript delete JSON elements - php

Question

I have this JSON string in a PHP page:
{
"elements": [{
"type": "pie",
"alpha": 0.3,
"animate": [{
"type": "fade"
}, {
"type": "bounce",
"distance": 5
}],
"start-angle": 0,
"tip": "#val# de #total# #percent#",
"colours": ["#d01f3c", "#356aa0", "#C79810"],
"values": [{
"value": 1,
"label": "procesador amd sempron 140"
}, {
"value": 1,
"label": "procesador sempron le130"
}, {
"value": 1,
"label": "procesador amd a4-3300 x2"
}, {
"value": 1,
"label": "procesador intel celeron g530"
}]
}],
"title": {
"text": "Procesadores, Reinicio",
"style": "color: #356aa0; font-size: 20px"
},
"bg_colour": "#FFFFFF",
"x_axis": null
}
I call it like this:
$.getJSON("restart_proce.php", function(json)
{
console.log(json);
I need to transform it to this:
[{\"value\": 1, \"label\": \"procesador amd sempron 140\" }, { \"value\": 1, \"label\": \"procesador sempron le130\" }, { \"value\": 1, \"label\": \"procesador amd a4-3300 x2\" }, { \"value\": 1, \"label\": \"procesador intel celeron g530\" } ]
I'm trying to delete elements like this:
delete json.elements[3];
but it doesn't delete anything. How can I make it work?

Answer 1

Removing an item from an Array:
There are several ways. The splice method is the most versatile:
data.items.splice(3, 1); // Removes three items starting with the 2nd,
splice modifies the original array, and returns an array of the items you removed.

Answer 2

Try this:
json.elements.splice(3, 1);
See: Array.splice

Answer 3

Just modify the values directly before console.log(json)
json= json.elements[0].values
Or in the restart_proce.php php page just echo
echo json_encode($data['elements'][0]['values']); // if associative array is used.

Answer 4

Try this:
var data = {"result":[
{"FirstName":"Test1","LastName":"User","Email":"test#test.com","City":"ahmedabad","State":"sk","Country":"canada","Status":"False","iUserID":"23"},
{"FirstName":"user","LastName":"user","Email":"u#u.com","City":"ahmedabad","State":"Gujarat","Country":"India","Status":"True","iUserID":"41"},
{"FirstName":"Ropbert","LastName":"Jones","Email":"Robert#gmail.com","City":"NewYork","State":"gfg","Country":"fgdfgdfg","Status":"True","iUserID":"48"},
{"FirstName":"hitesh","LastName":"prajapti","Email":"hitesh.prajapati#phptalent.com","City":"","State":"","Country":"","Status":"True","iUserID":"78"}
]
}
alert(data.result);
delete data.result[3];
alert(data.result);
working JSFiddle
or You can use splice to remove elements from an array.
