Parsing JSON array created from PHP array - javascript

{
"3": {
"id": "3",
"ocena_ocena": "2",
"ocena_profesor": "\u041c\u0430\u0440\u043a\u043e \u041c\u0430\u0440\u043a\u043e\u0432\u0438\u045b",
"ocena_napomena": "",
"ocena_datum": "31.12.2015."
},
"1": {
"id": "1",
"ocena_ocena": "5",
"ocena_profesor": "\u041c\u0430\u0440\u043a\u043e \u041c\u0430\u0440\u043a\u043e\u0432\u0438\u045b",
"ocena_napomena": "",
"ocena_datum": "22.12.2015."
}
}
I am using ajax to get this JSON. I tried parsing it like this:
request.done(function(response) {
alert(response.ocena_ocena);
});
Could someone please help me with this?
I also need to know how can I do a foreach statement with json?

Since your JSON represents a JavaScript object, you should include the attribute name (if we consider JavaScript object to be a map, then, we need to use the key).
Try
response["1"].ocena_ocena
or
response["3"].ocena_ocena
Since you are returning a JSON object from server instead of an array, to iterate over its properties, you could do
for (var i in response) {
console.log(response[i].ocena_ocena);
}
or
Object.keys(response).forEach(function f(e) {console.log(response[e].ocena_ocena)})
If you could modify your server side code to return JSON that looks like this,
[
{
"id": "3",
"ocena_ocena": "2",
...
},
{
"id": "1",
"ocena_ocena": "5",
...
}
]
then you could iterate over it more easily
response.forEach(function f(e) {console.log(e.ocena_ocena)})

How to access the right json value that is located through an array?

I'm currently using the fixture file to make sure it will be easier to call the right value.
cy.fixture('latestLead.json').then(function (lead) {
this.lead = lead
})
My son file is the following:
{
"status": 0,
"result": {
"totalSize": 1,
"done": true,
"records": [
{
"attributes": {
"type": "Lead",
"url": "/services/data/v51.0/sobjects/Lead/111111111"
},
"Id": "111111111",
"Name": "Andres Latest Test"
}
]
}
}
The way that I'm trying to get the right value is the following:
cy.get(".gLFyf").type(this.lead.result.records.Id)
I'm able to get totalSize or done from the result object, but I'm not able to get any other value higher than that object. How can I get the Id value from the records Array?
You can access an array item (in your case it's the object) using the index position (in your case it's zero)
cy.get(".gLFyf").type(this.lead.result.records[0].Id)
try this
cy.get(".gLFyf").type(this.lead.result.records[0].Id)

Geolib and getPreciseLocation through an Array

I have an array and I need to order the data of it by the distance of a specific point.
Knowing that .sort() won't work since I'm dealing with coordinates, I've been using a library called Geolib which has a function called getPreciseLocation() which is exactly what I need, but it doesn't seem to work while iterating through an array.
Here is the array containing the data I will be using.
Data:
[
{
"id": "1",
"Point": "27.1597268, 40.6646601"
},
{
"id": "2",
"Point": "11.1640393, 49.648713"
},
{
"id": "3",
"Point": "26.1539253, 42.6599287"
},
{
"id": "4",
"Point": "21.1597268, 44.6646601"
},
{
"id": "5",
"Point": "10.1640393, 43.648713"
},
{
"id": "6",
"Point": "26.1539253, 61.6599287"
}
]
The code I've been trying to use to iterate through the array.
let DistancesFromUserLocation = [];
this.state.Data.forEach(item => {
DistancesFromUserLocation.push(geolib.getPreciseDistance({latitude: 30.1891168, longitude: 11.6226982}, item.Point))
})
As a disclaimer: I only need to get to receive the distance of each array object to a new array.
I've tried and researched many things and get around the solution, but just about thinking that I am getting to the solution, something would go wrong.
You need to push the generated distance each iteration to DistancesFromUserLocation array.
let DistancesFromUserLocation = [];
this.state.Data.forEach(item => {
// push each distance to `DistancesFromUserLocation`
DistancesFromUserLocation.push(
geolib.getPreciseDistance(
{latitude: 30.1891168, longitude: 11.6226982},
item.Point
);
)
})
Only then you can use the Array.sort().
console.log(DistancesFromUserLocation.sort());
EDIT:
Check my working example here at codesandbox.

How can I combine this data into one Object?

This one is a tricky one.
So, lets say I have two JS objects that are fetched via REST call, via two callbacks.
So, we have:
call1() - POST method - parsed JSON to JS object, route: {{url}}/data
call1.json:
"data": [
{
"id": "1",
"volume:" "2000"
},
{
"id": "2",
"volume:" "3000"
},
{
"id": "3",
"volume:" "4000"
},
{
"id": "4",
"volume:" "5000"
}
];
call2(req.body.id) - GET method - parsed JSON to JS object, route: {{url}}/data/:id
For example, if I pass req.body.id as = 1 got from the first response, it will open data for that id. So:
return call2(2) will return the data from this JSON: call2.json:
"data": [
{
"id": "1",
"add_data": "important string",
"add_data_2": "important string two"
},
];
The bottom line is, when doing the {{url}}/data route call - call() I need to serve all the data from {{url}}/data/:id routes, and bind them to the correct id. So, for example, the scenario I am trying to achieve is this:
Inside call(): get call1.json: data, do as many call2(req.body.id) calls as there are ids in the first object and then combine add_data and add_data_two values in the first object. So for example the final object would look like this.
console.log(response)
"data": [
{
"id": "1",
"volume:" "2000",
"add_data": "important string",
"add_data_2": "important string two"
},
{
"id": "2",
"volume:" "3000",
"add_data": "important string",
"add_data_2": "important string two"
},
{
"id": "3",
"volume:" "4000",
"add_data": "important string",
"add_data_2": "important string two"
},
{
"id": "4",
"volume:" "5000",
"add_data": "important string",
"add_data_2": "important string two"
}
];
This is what I have tried so far:
async get_data(req) {
try {
const objFirst = await call1(); //gets data
let objTwo = '';
for (let i = 0; i < objFirst.data.length; i++) {
objTwo = await call2({id: objFirst.data[i].id}) //gets data
}
return objFirst;
} catch(err) {
console.log("Error: ", err)
}
}
But it does not work. How can I get all data, and make as many as call2(id) as there are ids and combine that all in one object? Basically, I need to repeat this callback -> call2(id) as many ids we receive in call1().
Thanks, sorry if it looks like a mess.
You can use the map function and spread operator for this. Something like below.
Call2 function just simulates what an endpoint would return, but you get the idea.
var data = [
{
id: 1,
add_data: "1111"
},
{
id: 2,
add_data: "2222"
}
];
var data2 = [
{
id: 1,
volume: "bla"
},
{
id: 2,
volume: "bla"
}
];
function call2(id) {
return data2.filter(x => x.id == id)[0];
}
var result = data.map(x => {
var response = call2(x.id);
return {
...x,
...response
}
})
console.dir(result[0]);
The speed of your solution (loop through an array and doing http calls to get more data is really slow). If you have a lot of these functions that needs to combine data from different datasources, and depending on your project size, i would look into either RXJS or GraphQL (If you really need performance). RXJS have great functions to merge, combine, map etc data.

How to parse a JSON array string in JavaScript?

I have an JSON array like this
var filter_value_data = [{"Status":[{"name":"Open","id":"1"},{"name":"Pending","id":"2"},{"name":"Resolved","id":"3"},{"name":"Closed","id":"4"},{"name":"Evaluation","id":"5"}]},{"Payment Status":[{"name":"Paid","id":"10"},{"name":"UnPaid","id":"11"},{"name":"Part Paid","id":"12"}]},{"Priority":[{"name":"Low","id":"6"},{"name":"Medium","id":"7"},{"name":"High","id":"8"},{"name":"Urgent","id":"9"}]}]
I have tried filter_value_data["Status"] which is obviously wrong. How do I get the JSON elements for Status using the names like Status,Payment Status?
filter_value_data is an array (having []), so use filter_value_data[0].Status to get the first element-object with property "Status".
It is always good to format your code in order to see the hierarchy of the structures:
var filter_value_data = [
{
"Status": [
{
"name": "Open",
"id": "1"
}, {
"name": "Pending",
"id": "2"
}, ...
]
}, {
"Payment Status": [
{
"name": "Paid",
"id": "10"
}, ...
]
}, {
"Priority": [
{
"name": "Low",
"id": "6"
}, ...
]
}
];
With your current JSON you can't get the elements with the name alone.
You can get Status with filter_value_data[0]['Status'] and Payment status with filter_value_data[1]['Payment Status'].
This is because the keys are in seperate objects in the array.
In order to get them with filter_value_data['Status'] you need to change your JSON to
var filter_value_data = {
"Status":[
{"name":"Open","id":"1"},
{"name":"Pending","id":"2"},
{"name":"Resolved","id":"3"},
{"name":"Closed","id":"4"},
{"name":"Evaluation","id":"5"}
],
"Payment Status":[
{"name":"Paid","id":"10"},
{"name":"UnPaid","id":"11"},
{"name":"Part Paid","id":"12"}
],
"Priority":[
{"name":"Low","id":"6"},
{"name":"Medium","id":"7"},
{"name":"High","id":"8"},
{"name":"Urgent","id":"9"}
]
};
I wrote this on my phone so it's not as well-formatted as usual. I'll change it ASAP.
With your current JSON, created a result which might be helpful for you.
JS:
$.each(filter_value_data,function(ind,val){
var sta = val.Status; // Status Object get displayed
for(var i=0;i<sta.length;i++){
var idVal= sta[i].id;
var nameVal = sta[i].name;
Statusarray.push(idVal,nameVal);
console.log(Statusarray);
}
})
FiddleDemo
You can use below code, it will return status object
filter_value_data[0]['Status']
filter_value_data[0]['Payment Status']
to get Single value you use :
filter_value_data[0]['Status'][0]['name']

Parse JSON with jQuery

I am trying to parse the following JSON with jQuery and get each id value. Can anyone advise?
[
{
"id": "1",
"name": "Boat"
},
{
"id": "2",
"name": "Cable"
}
]
So far I have:
$.each(test, function(i,item){
alert(item);
});
But that simply lists every value. How can I
That'll list every object in your array, to get the id property of the one you're on, just add .id like this:
$.each(test, function(i,item){
alert(item.id);
});
If test is a string containing JSON, you can parse it with jQuery.parseJSON, which will return a JavaScript object.
If test is written like this:
var test = [
{
"id": "1",
"name": "Boat"
},
{
"id": "2",
"name": "Cable"
}
];
...it already is a JavaScript object; specifically an array. jQuery.each will loop through each array entry. If you want to loop through the properties of those entries as well, you can use a second loop:
$.each(test, function(outerKey, outerValue) {
// At this level, outerKey is the key (index, mostly) in the
// outer array, so 0 or 1 in your case. outerValue is the
// object assigned to that array entry.
$.each(outerValue, function(innerKey, innerValue) {
// At this level, innerKey is the property name in the object,
// and innerValue is the property's value
});
});
