Issues with JSON formatting for data object in Grafana

Data is not coming in with proper JSON formatting, so I'm having to loop through items in the array to fix the formatting, parsing the changed items and I cannot use the new object(s) when everything is finished because it is no longer in an array. The data is coming in as follows:
data [datapoints: [0..1..]
target: "up{cluster="bluehills_c3260_cluster",component="atr",datacenter="bluehills",hostname="ny-153-177"...}"]
Is there an easier way to convert this using a .map function or some other method to make things cleaner and get the desired result?
I've tried several methods including .replace, .map, and .push. I've also tried JSON.stringify, but nothing else seems to work except what I currently have.
onDataReceived(data) {
var i;
for (i = 0; i < data.length; i++) { // Loop through data array
var txt = data[i].target; // Create the variable to store the data target
var j;
for (j = 0; j <= txt.length; j++) { // Loop through the data target
var newObj = txt.slice(2,j); // Remove "up"
var filteredObj = newObj // Change over to JSON format...
.replace(/=/g,' : ')
.replace(/,/g,', ')
.replace(/{/g,'{ ')
.replace(/cluster/g,'"cluster"')
.replace(/component/g,'"component"')
.replace(/datacenter/g,'"datacenter"')
}
var dataObj = filteredObj.replace(/_"cluster"/gi,'_cluster');
var finalObj = JSON.parse(dataObj);
console.log("finalObj", dataObj);
}
}
What I want is a single array with the proper JSON format for the data (target) coming in.

How about this?
const myReg = /([\w\s]+)=\"([^"]*)\"/g
const str = `data [datapoints: [0..1..] target: "up{cluster="bluehills_c3260_cluster",component="atr",datacenter="bluehills",hostname="ny-153-177"...}"]`;
let matches = null;
const resultsJson = {};
while(matches = myReg.exec(str)){
resultsJson[matches[1]] = matches[2];
}
{ cluster: 'bluehills_c3260_cluster',
component: 'atr',
datacenter: 'bluehills',
hostname: 'ny-153-177' }
Not sure if this is how you want to have the data stored but that part would be pretty easy to customize.

onDataReceived(data){
this.createCosmo(data);
}
createCosmo(data) {
var arr = $.map(data,function(value){
return value.target;
});
var arr2 = $.map(arr,function(value){
var newObj = value.slice(2); // Remove "up"
var filteredObj = newObj // Change over to JSON format
.replace(/=/g,' : ')
.replace(/,/g,', ')
.replace(/{/g,'{ ')
.replace(/cluster/g,'"cluster"')
.replace(/component/g,'"component"')
.replace(/datacenter/g,'"datacenter"')
.replace(/hostname/g,'"hostname"')
.replace(/instance/g,'"instance"')
.replace(/job/g,'"job"')
.replace(/resilience_group/g,'"resilience_group"')
.replace(/_"cluster"/gi,'_cluster')
.replace(/-"cluster"/gi,'-cluster');
var finalObj = JSON.parse(filteredObj); // Parse the Object into JSON
return finalObj;
});
}

push only unique elements in an array

I have array object(x) that stores json (key,value) objects. I need to make sure that x only takes json object with unique key. Below, example 'id' is the key, so i don't want to store other json objects with 'item1' key.
x = [{"id":"item1","val":"Items"},{"id":"item1","val":"Items"},{"id":"item1","val":"Items"}]
var clickId = // could be "item1", "item2"....
var found = $.inArray(clickId, x); //
if(found >=0)
{
x.splice(found,1);
}
else{
x.push(new Item(clickId, obj)); //push json object
}

would this accomplish what you're looking for? https://jsfiddle.net/gukv9arj/3/
x = [
{"id":"item1","val":"Items"},
{"id":"item1","val":"Items"},
{"id":"item2","val":"Items"}
];
var clickId = [];
var list = JSON.parse(x);
$.each(list, function(index, value){
if(clickId.indexOf(value.id) === -1){
clickId.push(value.id);
}
});

You can't use inArray() because you are searching for an object.
I'd recommend rewriting a custom find using Array.some() as follows.
var x = [{"id":"item1","val":"Items"},{"id":"item1","val":"Items"},{"id":"item1","val":"Items"}]
var clickId = "item1";
var found = x.some(function(value) {
return value.id === clickId;
});
alert(found);

Almost 6 years later i ended up in this question, but i needed to fill a bit more complex array, with objects. So i needed to add something like this.
var values = [
{value: "value1", selected: false},
{value: "value2", selected: false}
//there cannot be another object with value = "value1" within the collection.
]
So I was looking for the value data not to be repeated (in an object's array), rather than just the value in a string's array, as required in this question. This is not the first time i think in doing something like this in some JS code.
So i did the following:
let valueIndex = {};
let values = []
//I had the source data in some other and more complex array.
for (const index in assetsArray)
{
const element = assetsArray[index];
if (!valueIndex[element.value])
{
valueIndex[element.value] = true;
values.push({
value: element.value,
selected: false
});
}
}
I just use another object as an index, so the properties in an object will never be repated. This code is quite easy to read and surely is compatible with any browser. Maybe someone comes with something better. You are welcome to share!
Hopes this helps someone else.

JS objects are great tools to use for tracking unique items. If you start with an empty object, you can incrementally add keys/values. If the object already has a key for a given item, you can set it to some known value that is use used to indicate a non-unique item.
You could then loop over the object and push the unique items to an array.
var itemsObj = {};
var itemsList = [];
x = [{"id":"item1","val":"foo"},
{"id":"item2","val":"bar"},
{"id":"item1","val":"baz"},
{"id":"item1","val":"bez"}];
for (var i = 0; i < x.length; i++) {
var item = x[i];
if (itemsObj[item.id]) {
itemsObj[item.id] = "dupe";
}
else {
itemsObj[item.id] = item;
}
}
for (var myKey in itemsObj) {
if (itemsObj[myKey] !== "dupe") {
itemsList.push(itemsObj[myKey]);
}
}
console.log(itemsList);
See a working example here: https://jsbin.com/qucuso
If you want a list of items that contain only the first instance of an id, you can do this:
var itemsObj = {};
var itemsList = [];
x = [{"id":"item1","val":"foo"},
{"id":"item2","val":"bar"},
{"id":"item1","val":"baz"},
{"id":"item1","val":"bez"}];
for (var i = 0; i < x.length; i++) {
var item = x[i];
if (!itemsObj[item.id]) {
itemsObj[item.id] = item;
itemsList.push(item);
}
}
console.log(itemsList);

This is late but I did something like the following:
let MyArray = [];
MyArray._PushAndRejectDuplicate = function(el) {
if (this.indexOf(el) == -1) this.push(el)
else return;
}
MyArray._PushAndRejectDuplicate(1); // [1]
MyArray._PushAndRejectDuplicate(2); // [1,2]
MyArray._PushAndRejectDuplicate(1); // [1,2]

This is how I would do it in pure javascript.
var x = [{"id":"item1","val":"Items"},{"id":"item1","val":"Items"},{"id":"item1","val":"Items"}];
function unique(arr, comparator) {
var uniqueArr = [];
for (var i in arr) {
var found = false;
for (var j in uniqueArr) {
if (comparator instanceof Function) {
if (comparator.call(null, arr[i], uniqueArr[j])) {
found = true;
break;
}
} else {
if (arr[i] == uniqueArr[j]) {
found = true;
break;
}
}
}
if (!found) {
uniqueArr.push(arr[i]);
}
}
return uniqueArr;
};
u = unique(x, function(a,b){ return a.id == b.id; });
console.log(u);
y = [ 1,1,2,3,4,5,5,6,1];
console.log(unique(y));

Create a very readable solution with lodash.
x = _.unionBy(x, [new Item(clickId, obj)], 'id');

let x = [{id:item1,data:value},{id:item2,data:value},{id:item3,data:value}]
let newEle = {id:newItem,data:value}
let prev = x.filter(ele=>{if(ele.id!=new.id)return ele);
newArr = [...prev,newEle]

How can i get the fields of an index from elastic search?

I have JSON object returned from elastic search like below, I am able to get the data using this,
$scope.results = response.hits.hits;
console.log($scope.results);
var resultstofilter = [];
var resultArray = [];
for (var i=0; i<$scope.results.length; ++i) {
var result = $scope.results[i];
resultstofilter[i] = {};
for (var key in result) {
if (key === '_source' || key === 'Calls') {
var Oriobj = result[key];
resultArray.push(Oriobj);
console.log(resultArray);
$scope.resultData = resultArray;
}
}
}
for(var key in $scope.resultData) {
}
});
Result:
I need to get the fields of an index. Say in this sample.
Agent
Calls
Is there a way i can directly get the value of key like we do in c#.Something like this,
$scope.resultData["key"];

There are many ways. One of them is to use underscore _.pluck
var getIndex = _.pluck($scope.resultData,'_index');
Or:
$scope.resultData.filter(function(myObject) {
for (var prop in myObject) {
if (myObject.hasOwnProperty(prop)) {
$scope.fieldsOfIndex.push(prop);
}
}
});

How to convert arrays into an array of objects

Hi I'm trying to make an array of objects from several arrays.This is probably a very basic question, but I didn't find a proper way of doing it from searching online. :(
The original data I've got is
valueYes = [15,30,22,18,2,6,38,18];
valueNo = [23,75,45,12,45,9,17,23];
valueNotSure = [1,-1,1,1,-1,-1,-1,1];
What I want to achieve is an array like :
data = [object1, object2,.....]
Each object is made of :
object1 = {valueYes:15, valueNo:23,valueNotSure:1}
object2 = {valueYes:30, valueNo:75,valueNotSure:-1}
.......
my current code is a bit messy, which only return me an empty value of each key:
valueYes = [15,30,22,18,2,6,38,18];
valueNo = [23,75,45,12,45,9,17,23];
valueNotSure = [1,-1,1,1,-1,-1,-1,1];
var object1 = Object.create({}, {
myChoice: { value: function(myChoice) {for (var i = 0; i < len; i++){return this.myChoice[i] = myChoice[i];} } }
});

Assuming all your arrays have the same size:
valueYes = [15,30,22,18,2,6,38,18];
valueNo = [23,75,45,12,45,9,17,23];
valueNotSure = [1,-1,1,1,-1,-1,-1,1];
var data = [];
for(var i = 0; i < valueYes.length; i++){
data.push({
valueYes: valueYes[i],
valueNo: valueNo[i],
valueNotSure: valueNotSure[i]
});
}

You could use something like below;
var objs = valueYes.map(function (v, i) {
return {
valueYes: v,
valueNo: valueNo[i],
valueNotSure: valueNotSure[i]
};
});
... this uses the map() Array method, and assumes that all the arrays are the same length...

This?
var valueYes = [15,30,22,18,2,6,38,18];
var valueNo = [23,75,45,12,45,9,17,23];
var valueNotSure = [1,-1,1,1,-1,-1,-1,1];
var data = [];
valueYes.forEach(function(item, index) {
data.push({ valueYes: valueYes[index], valueNo: valueNo[index], valueNotSure: valueNotSure[index] });
});
console.log(data);

Concatenate to access an object property [duplicate]

This question already has answers here:
Closed 10 years ago.
Possible Duplicate:
Dynamic object property name
I want to dynamically generate access to an object's property.
If I try to access mydata[i].val.name I get somename.
If I try it like mydata[i] + bar[j] (where bar[j] === '.val.name') it fails.
How do I dynamically create something like this? So that I can access any property of an object using a user generated value?
Some code:
If I have an object I want to be able to iterate through its properties, gathering the ones I am interested in. Ideally I would like something like the following:
var processData = function (data, keys, values) {
var returnData = [], i, j, k;
var parsedData = JSON.parse(data);
var keys = keys || null;
var values = values || null;
var datalen = parsedData.length;
for (i = 0; i < datalen; i++) {
returnData[i] = {};
for(j = 0; j< keys.length; j++){
for(k = 0; k < values.length; k++){
returnData[i][keys[j]] = parsedData[i] + values;
}
}
}
return returnData;
};
and then use it like:
var keys = ["foo","bar"];
var values = [".val.name", ".val.date"];
processData(data, keys, values);
But this does not work and in console I see foo="[object Object].val.name" rather than the expected foo="ACME Industries".

If you want to stick to your pattern of constructing the subscript as a string with dots in it you have to roll your own lookup function, like so:
function descend(object, sub) {
var handle = object,
stack = sub.split('.'),
history = [],
peek;
while (handle[stack[0]]) {
if (peek) {
history.push(peek);
}
peek = stack.shift();
handle = handle[peek];
}
if (stack.length > 0) {
history.push(peek);
throw "Traversal error, could not descend to '" + stack.join('.') + "' from '" + history.join('.') + "'.";
}
return handle;
}
var x = {
a: {
b: {
c: 15
},
d: 4
}
};
console.log(descend(x, "a"));
console.log(descend(x, "a.b"));
console.log(descend(x, "a.b.c"));
console.log(descend(x, "a.d"));
function processData(data, keys, values) {
if (keys.length !== values.length) {
throw "Mismatched keys and value lookups";
}
var i,
len = keys.length,
gathered = {},
k,
scratch,
v;
for (i = 0; i < len; i += 1) {
k = descend(data, keys[i]);
scratch = values[i].split('.');
scratch.shift();
v = descend(k, scratch.join('.'));
gathered[keys[i]] = v;
}
return gathered;
}
var data = {
foo: {
val: {
name: "ACME Industries"
}
},
bar: {
val: {
date: (new Date())
}
}
};
var keys = ["foo","bar"];
var values = [".val.name", ".val.date"];
processData(data, keys, values);
Please note: this will not be nearly as performant as coding without this style of lookup.

If you try:
new Object() + '.john.doe'
It will concatenate as a string, so you’ll get "[object Object].john.doe".
You should create a function that can handle dynamic property names instead (and there are plenty of those). You also might want to loose the ".foo.bar" syntax as a string (unless you plan to use eval()) and work solely with arrays instead.

If I understand correctly you need to use
mydata[i]["val"]["name"]
So, I'd use something like this:
var result =getItemByValuesPath(myData[i],values);
alert(result);
function getItemByValuesPath(item, values)
{
var result = item;
var vals = values.split(".");
for(var j=0; j<values.length; j++)
{
if(result==undefined)
{
return null;
}
result = result[values[j]];
}
}
