Here I have this code jquery:
JSON.stringify($("#vrsta_rada").select2("data"));
and I get this JSON file:
"[{"id":2,"text":"setva/zasad"},{"id":6,"text":"orezivanje"},{"id":8,"text":"skladistenje"}]"
How I can use .each function to get this string: data[0].text, data[1].text ...
so to get string from JSON above: setva/zasad, orezivanje, skladistenje
?
I'm not sure why you are stringifying the data if you want to manipulate it. So this will work:
var data = $("#vrsta_rada").select2("data");
$.each(data, function(key, value) {
var text = data[key].text
//or
var text = value.text
});
Is this what you are looking for? That will iterate through the list. I prefer to use data[key] because you can then manipulate the data and it will change the original whereas value only makes a copy.
Try
$.each(data, function(index, value) {
alert(value.text)
});

Hello I have a json data like this
KLOBS {"SL_VEF_APPLIED_VS_BOL_R1_KLOBS":["0.00247320692497939","0.000008129750823137272"]}
KL15 {"SL_VEF_APPLIED_VS_BOL_R1_KL15":["0.01890831252229754","0.9008162336184189"]}
I'm already try extract json
$.get('url_request.php?' + $(this).serialize(), function(data) {
var obj = data;
$.each(obj, function(key, value) {
console.log(key);
console.log(value);
});
});
$.each(obj, function(key, value) {
console.log(key);
console.log(value);
});
And I get result
KLOBS
{"SL_VEF_APPLIED_VS_BOL_R1_KLOBS":["0.00247320692497939","0.000008129750823137272"]}
KL15
{"SL_VEF_APPLIED_VS_BOL_R1_KL15":["0.01890831252229754","0.9008162336184189"]}
I want to get result like this:-
KLOBS
0.00247320692497939
0.000008129750823137272
KL15
0.01890831252229754
0.9008162336184189
How to call json like this ??
I don't know call multiple value data in Json.
Please help me.
Try this
var arr = {
KLOBS: {
SL_VEF_APPLIED_VS_BOL_R1_KLOBS: [
"0.00247320692497939",
"0.000008129750823137272"
]
},
KL15: {
SL_VEF_APPLIED_VS_BOL_R1_KL15: ["0.01890831252229754", "0.9008162336184189"]
}
};
Object.keys(arr).forEach(function(key, value) {
console.log(key);
Object.keys(arr[key]).forEach(function(val) {
arr[key][val].forEach(function(data) {
console.log(data);
});
});
});
In general you could do the following:
var KLOBS = {"SL_VEF_APPLIED_VS_BOL_R1_KLOBS":
["0.00247320692497939","0.000008129750823137272"]}
values = Object.keys(KLOBS).map(x=>{
return KLOBS[x];
})
values.forEach(x=>x.forEach(y=>console.log(y)))

Object.keys gives you an array of the keys in an object.
Since I do not know the structure in advance, I assume it better thinking of more than one key.
With the function map, a function is applied to each member of the array returned by Object.keys. This is used to extract the values.
The resulting structure is an array of arrays.
Therefore a double forEach is needed to display every entry of the structure.
I'm trying to iterate over this json encoded array which is a string:
"{"":{"count":{"total":112,"open":0,
"solved":0,
"deleted":106,
"closed":6},
"average_time_open_in_minutes":206,
"tickets_fortnight_week_count":11,
"tickets_last_week_count":15,"trend":1},
"Net2grid":{"count":"total":8,"open":0,"solved":0,"deleted":8},"average_time_open_in_minutes":0,"tickets_fortnight_week_count":0,"tickets_last_week_count":0,"trend":0},"Closed_by_merge":{"count":{"total":2,"open":0,"solved":0,"closed":2},"average_time_open_in_minutes":502,"tickets_fortnight_week_count":0,"tickets_last_week_count":0,"trend":0},"Analytics":{"count":{"total":1,"open":0,"solved":0,"deleted":1},"average_time_open_in_minutes":26,"tickets_fortnight_week_count":0,"tickets_last_week_count":0,"trend":0},"Meter":{"count":{"total":5,"open":5,"solved":0},"average_time_open_in_minutes":0,"tickets_fortnight_week_count":0,"tickets_last_week_count":2,"trend":1},"Installation":{"count":{"total":8,"open":5,"solved":3},"average_time_open_in_minutes":404,"tickets_fortnight_week_count":0,"tickets_last_week_count":0,"trend":0},"Other...":{"count":{"total":3,"open":2,"solved":1},"average_time_open_in_minutes":39,"tickets_fortnight_week_count":0,"tickets_last_week_count":0,"trend":0},"Meter Offline":{"count":{"total":8,"open":7,"solved":1},"average_time_open_in_minutes":8,"tickets_fortnight_week_count":0,"tickets_last_week_count":0,"trend":0},"App Usage":{"count":{"total":6,"open":5,"solved":0,"deleted":1},"average_time_open_in_minutes":8,"tickets_fortnight_week_count":0,"tickets_last_week_count":0,"trend":0}}"
An ajax call returns that string and i'm trying to only get the keys like: "app usage" and "Meter Offline" to return like so:
$.get('/ajax/ticket-and-notes-data.php', function (data) {
var problems = getProblems(data);
function getProblems(problems) {
var problemCategories = [];
$.each(JSON.parse(problems), function (key, value) {
if (key != "") {
problemCategories.push = key;
}
});
return problemCategories;
}
});
But I can't get the keys to go into the problemCategories.
I use this to set the categories in a highchart bubble chart and I will use more of the data from the string later.
I need to get this to work first.
The issue is in the way that you're using array.push. You should use array.push(item) instead of array.push = item.
I want to parse the following json:
{"key_410441":{"hashId":"hash123","tube_id":"4accdefk31"}}
Where key_410441 is the entry's name representing the object's value, and the following array is the object's data.
How can I retrieve it's value?
function defined(json) {
for (var i in json) {
var objId = json[i]. ????
}
}
Like Robo Robok said, use Object.keys(object)
if your json look like {"key_410441":{"hashId":"hash123","tube_id":"4accdefk31"}}
function defined(json) {
var hashId = json[Object.keys(json)[0]].hashId
var tube_id = json[Object.keys(json)[0]].tube_id
}
}
you can use shortcut json[Object.keys(json)] because you have olny one object
key_410441
Object keys are returned in form of an array by Object.keys(object)
I suppose you are using jquery and ajax to get a json from an external file. Then the piece of code would be:-
$.getJSON("aa.json", function(data) {
var obj = Object.keys(data),
json = data[obj];
for(var s in json) {
console.log(json[s]);
}
});
{
"id":["123"],
"optionid_123":"98"
}
I have the id as a variable, but from that how can I get the optionid_*? I tried a few things, but nothing seems to work. The each is inside of the appropriate function and jsonid contains the correct value. Here is my attempt at accessing the value 98 which doesn't work:
$.each(data.id,function(){
var jsonid = this;
console.log( data.optionid_+jsonid ); // doesn't work
});
You can use Bracket notation:
console.log( data['optionid_' + jsonid] );
I think your loop with data.id is not correct. That is
$.each(data.id, function() {..})
is incorrect.
For example if you data looks like following:
var data = [{
"id":["123"],
"optionid_123":"98"
},
{
"id":["456"],
"optionid_456":"99"
}];
Then you need to loop over data and get your required property.
$.each(data, function(index, val) {
var jsonid = val.id[0]; // as val.id is array so you need [0] to get the value
console.log(val['optionid_' + jsonid]); // bracket notation used
});

i am very new to play with JSON. I need to iterate over JSON response coming from AJAX, actually, i am fetching checkboxe values from db table in the form on 2,3,7,9,3. Now i am stuck with iteration on each number.
If you run following code in FF console area you will notice it is looping against each numeric NOT THE VALUE.
Please guide me.
var srv = {"services":"26,29"};
jQuery.each( srv.services, function(i, v) {
console.log( v );
});
Any help would be appreciated.
THanks :)
srv.services is a string of comma separated values, so $.each() won't work correctly. You can split() it into an array, though:
var srv = {"services":"26,29"};
jQuery.each(srv.services.split(","), function(i, v) {
console.log( v );
});
Working demo: http://jsfiddle.net/AndyE/veP4p/
You could also have your JSON service return an array instead of a string, e.g. {"services":[26, 29]}. This would be done for you automatically at the server if you're using proper JSON-compliant methods to encode and if the data is an array.
it is not valid json array, your json data should be something like this:
var srv = {"services": ["26", "29"]};
..or of-cause you could split your string data using js split function:
jQuery.each(srv.services.split(","), function(i, v) {
console.log( v );
});
Not sure this is an answer to your problem but given the declaration from above, try splitting on , before iterating:
var srv = {"services":"26,29"};
jQuery.each( srv.services.split(','), function(i, v) {
console.log( v );
});
(Demo)
You have to create an array first
var srv = {"services":"26,29".split(",")};
jQuery.each( srv.services, function(i, v) {
console.log( v );
});
