Add the X values in Json with respect to Image

Add the X values in Json with respect to Image - javascript

In a Json, there are multiple image sources as "src" : "image.png", , "src" : "image2.png",
For image.png , right now i am fetching X value as "40" [3rd position in below image]
For image2.png , right now i am fetching X value as "100" [6th position in below image]
Requirement :
Instead of that, i need to add 1st (10) + 3rd (40) + 4th (50) positions values and fetch final X value for "src" : "image.png", as 100 [10+40+50] and
"src" : "image1.png" = 1st (10) + 6th (100) + 7th (105) positions & final value of X is 215....

let jsonData = {
"layers" : [
{
"x" : 10,
"layers" : [
{
"x" : 20,
"y" : 30,
"name" : "L2a"
},
{
"x" : 40,
"layers" : [
{
"x" : 50,
"src" : "image.png",
"y" : 60,
"name" : "L2b-1"
},
{
"x" : 70,
"y" : 80,
"name" : "L2b-2"
}
],
"y" : 90,
"name" : "user_image_1"
},
{
"x" : 100,
"layers" : [
{
"x" : 105,
"src" : "image2.png",
"y" : 110,

function getData(data) {
var dataObj = {};
let layer1 = data.layers;
let layer2 = layer1[0].layers;
for (i = 1; i < layer2.length; i++) {
var x = layer2[i].x;
var src = layer2[i].layers[0].src;
document.write("src :" + src);
document.write("<br>");
document.write("x:" + x);
document.write("<br>");
}
}
getData(jsonData);

Using a recursive function you can find all the src and its corresponding summed x values.
Below is a crude example. Refactor as you see fit.
let jsonData = {
"layers" : [
{
"x" : 10,
"layers" : [
{
"x" : 20,
"y" : 30,
"name" : "L2a"
},
{
"x" : 40,
"layers" : [
{
"x" : 50,
"src" : "image.png",
"y" : 60,
"name" : "L2b-1"
},
{
"x" : 70,
"y" : 80,
"name" : "L2b-2"
}
],
"y" : 90,
"name" : "user_image_1"
},
{
"x" : 100,
"layers" : [
{
"x" : 105,
"src" : "image2.png",
"y" : 110,
"name" : "L2C-1"
},
{
"x" : 120,
"y" : 130,
"name" : "L2C-2"
}
],
"y" : 140,
"name" : "L2"
}
],
"y" : 150,
"name" : "L1"
}
]
};
function getAllSrc(layers){
let arr = [];
layers.forEach(layer => {
if(layer.src){
arr.push({src: layer.src, x: layer.x});
}
else if(layer.layers){
let newArr = getAllSrc(layer.layers);
if(newArr.length > 0){
newArr.forEach(({src, x}) =>{
arr.push({src, x: (layer.x + x)});
});
}
}
});
return arr;
}
function getData(data) {
let arr = getAllSrc(data.layers);
for (let {src, x} of arr){
document.write("src :" + src);
document.write("<br>");
document.write("x:" + x);
document.write("<br>");
}
}
getData(jsonData);
Here is the CodePen for the same: https://codepen.io/anon/pen/Wmpvre
Hope this helps :)

You can do that using recursion. While going though nested obj you could parent x value each item in layers and check if the element in layers have src property add the previous x value to it.
let jsonData = {
"layers" : [
{
"x" : 10,
"layers" : [
{
"x" : 20,
"y" : 30,
"name" : "L2a"
},
{
"x" : 40,
"layers" : [
{
"x" : 50,
"src" : "image.png",
"y" : 60,
"name" : "L2b-1"
},
{
"x" : 70,
"y" : 80,
"name" : "L2b-2"
}
],
"y" : 90,
"name" : "user_image_1"
},
{
"x" : 100,
"layers" : [
{
"x" : 105,
"src" : "image2.png",
"y" : 110,
"name" : "L2C-1"
},
{
"x" : 120,
"y" : 130,
"name" : "L2C-2"
}
],
"y" : 140,
"name" : "L2"
}
],
"y" : 150,
"name" : "L1"
}
]
};
function changeData(obj,x=0){
if(obj.src) obj.x += x;
if(obj.layers){
for(const item of obj.layers){
changeData(item,x+obj.x || 0);
}
}
}
changeData(jsonData);
function showData(obj){
if(obj.src) document.body.innerHTML += `src:${obj.src}<br>
x:${obj.x}<br>`;
if(obj.layers){
for(let i of obj.layers) showData(i)
}
}
showData(jsonData);
console.log(jsonData);

Here is my solution with recursion and mutation. You can cloneDeep the array before if you don't want to mutate it directly.
// Code
function recursion(obj, currentX = 0) {
if(obj.src) obj.x = currentX
else if(obj.layers) {
obj.layers.forEach(subObj => recursion(subObj, (currentX + subObj.x)))
}
}
// Data
let jsonData = {
"layers" : [
{
"x" : 10,
"layers" : [
{
"x" : 20,
"y" : 30,
"name" : "L2a"
},
{
"x" : 40,
"layers" : [
{
"x" : 50,
"src" : "image.png",
"y" : 60,
"name" : "L2b-1"
},
{
"x" : 70,
"y" : 80,
"name" : "L2b-2"
}
],
"y" : 90,
"name" : "user_image_1"
},
{
"x" : 100,
"layers" : [
{
"x" : 105,
"src" : "image2.png",
"y" : 110,
"name" : "L2C-1"
},
{
"x" : 120,
"y" : 130,
"name" : "L2C-2"
}
],
"y" : 140,
"name" : "L2"
}
],
"y" : 150,
"name" : "L1"
}
]
};
// Use
recursion(jsonData)
console.log(jsonData)

let jsonData = {
"layers": [{
"x": 10,

function getData(data) {

let layer1 = data.layers;
let layer2 = layer1[0].layers;
let y = layer1[0].x;
for (i = 1; i < layer2.length; i++) {
var x = y;
x += layer2[i].x;

var src = layer2[i].layers[0].src;
document.write("src :" + src);

getData(jsonData);
getData(jsonData2);

the json part is ok. But after that in
var mask1 = $(".container").mask({
maskImageUrl: maskedImageUrla, // get image
you create only one image, with the last value of maskedImageUrla.
What you can do is store your images in an array and iterate over them, as in :
$.getJSON('2images.json', function(json)
{
const images = [];
for (let layer of json.layers)
...
for (let tl of temp.layers)
if (tl.src) {
images.push({
maskedImageUrla = 'http://piccellsapp.com:1337/parse/files/PfAppId/' + tl.src,
coordinates.x = temp.x,
coordinates.y = temp.y
})
}
...
images.forEach(image => {
var mask1 = $(".container").mask({
maskImageUrl: image.maskedImageUrla, // get image
onMaskImageCreate: function(img) {
img.css({
"position": "fixed",
"left": image.coordinates.x + "px", // get x
"top": image.coordinates.y + "px" // get y
});
}
});
fileupa1.onchange = function() {
mask1.loadImage(URL.createObjectURL(fileupa1.files[0]));
};
});

Cannot access a field in JSON

I am trying to access an image in a JSON response however the field I need to access is an id value that is unique or rather is random. We are fetching this data from a server so we cannot hard code the id's.
The JSON is as follows:
{ "error" : { "occured" : "false" },
"errors" : [ ],
"executiontime" : 2500,
"metadata" : { },
"value" : [ { "activity_duration" : "1 hour, ½ day & full day packages",
"adult_rate_high_period_high_price" : 275,
"adult_rate_high_period_low_price" : 49,
"adult_rate_low_period_high_price" : "",
"adult_rate_low_period_low_price" : "",
"amenities" : [ ],
"assets" : { "logo" : { "436209" : { "asset_type" : "image",
"caption" : "",
"credit" : "",
"description" : "",
"exists" : "true",
"height" : 82,
"label" : "Copy of Monarch logo",
"latitude" : 0,
"longitude" : 0,
"market" : "$",
"o_id" : 3221685,
"type_o_id" : 2543991,
"unique_id" : 436209,
"url" : "http://c0481729.cdn2.cloudfiles.rackspacecloud.com/p-DD951E3E-C7AF-F22C-77E98D299833B38F-2544001.jpg",
"width" : 220
} },
We are trying to display the business logo for each amenity. To do this I need to access the url field in the above JSON. How do I access the url field under assest.

The Problem is to get the id of the Logo 436209.
var theid;
var l = obj.value[0].assets.logo
for (var p in l) {
if (l[p].hasOwnProperty('unique_id')) {
theid = l[p].unique_id;
break;
}
}
This is untestet. The idee is to use the in-operator to iterate over the properties of the logo-object and get the propterty that has the unique_id.

Correction:
obj.value[0].assets.logo["436209"].url = 'foo';
// or
var foo = obj.value[0].assets.logo["436209"].url;
This assumes that your object is well formed and continues with more parts of obj.value[0].
Specifically, if your object were completed, perhaps, like this:
var obj = {
"error": { "occured": "false" },
"errors": [],
"executiontime": 2500,
"metadata": {},
"value": [{
"activity_duration": "1 hour, ½ day & full day packages",
"adult_rate_high_period_high_price": 275,
"adult_rate_high_period_low_price": 49,
"adult_rate_low_period_high_price": "",
"adult_rate_low_period_low_price": "",
"amenities": [],
"assets": {
"logo": {
"436209": {
"asset_type": "image",
"caption": "",
"credit": "",
"description": "",
"exists": "true",
"height": 82,
"label": "Copy of Monarch logo",
"latitude": 0,
"longitude": 0,
"market": "$",
"o_id": 3221685,
"type_o_id": 2543991,
"unique_id": 436209,
"url": "http://c0481729.cdn2.cloudfiles.rackspacecloud.com/p-DD951E3E-C7AF-F22C-77E98D299833B38F-2544001.jpg",
"width": 220
}
}
}
}]
};

Formatting JSON document to specification needed for visualization

I'm attempting to create a Google Chart based on data in Elastic Search. The JSON document needs to be in the following format:
{
"cols": [
{"id":"","label":"Lane","type":"string"},
{"id":"","label":"Routes","type":"number"}
],
"rows": [
{"c":[{"v":"M01"},{"v":4657}]},
{"c":[{"v":"M02"},{"v":4419}]},
{"c":[{"v":"M03"},{"v":4611}]},
{"c":[{"v":"M04"},{"v":4326}]},
{"c":[{"v":"M05"},{"v":4337}]},
{"c":[{"v":"M06"},{"v":5363}]}
]
}
My query (via ajax command) returns the following data:
$ curl http://localhost:9200/wcs/routes/_search?pretty=true -d '{"query_all":{}}}'
{
"took" : 2,
"timed_out" : false,
"_shards" : {
"total" : 5,
"successful" : 5,
"failed" : 0
},
"hits" : {
"total" : 7,
"max_score" : 1.0,
"hits" : [ {
"_index" : "wcs",
"_type" : "routes",
"_id" : "4",
"_score" : 1.0, "_source" : {"lane":"M04","routes":"102"}
}, {
"_index" : "wcs",
"_type" : "routes",
"_id" : "5",
"_score" : 1.0, "_source" : {"lane":"M03","routes":"143"}
}, {
"_index" : "wcs",
"_type" : "routes",
"_id" : "1",
"_score" : 1.0, "_source" : {"lane":"M07","routes":"80"}
}, {
"_index" : "wcs",
"_type" : "routes",
"_id" : "6",
"_score" : 1.0, "_source" : {"lane":"M02","routes":"157"}
}, {
"_index" : "wcs",
"_type" : "routes",
"_id" : "2",
"_score" : 1.0, "_source" : {"lane":"M06","routes":"101"}
}, {
"_index" : "wcs",
"_type" : "routes",
"_id" : "7",
"_score" : 1.0, "_source" : {"lane":"M01","routes":"105"}
}, {
"_index" : "wcs",
"_type" : "routes",
"_id" : "3",
"_score" : 1.0, "_source" : {"lane":"M05","routes":"160"}
} ]
}
}
The HTML/JS that I'm attempting to run (and currently returns nothing) is as follows. Could someone provide some insight as to what I may be doing wrong? It would be greatly appreciated.
<html>
<head>
<script type="text/javascript" src="https://www.google.com/jsapi"></script>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>
<script type="text/javascript">
google.load('visualization', '1', {'packages':['corechart']});
google.setOnLoadCallback(drawChart);
function drawChart() {
var jsonData = $.ajax({
url: 'http://localhost:9200/wcs/routes/_search?pretty=true'
, type: 'POST'
, data :
JSON.stringify(
{
"query" : { "match_all" : {} }
})
, dataType : 'json'
async: false
});
var json = JSON.parse(jsonData);
var jdata = '{ "cols": [{"id":"", "label":"lane", "type": "string"},' + '{"id": "", "label": "routes", "type": "number"}],' + '"rows":[{"c": [{"v":' + json.hits[0].hits[0]._source.lane + '},{"v":' + json.hits[0].hits[0]._source.routes + '}]}]';
var data = new google.visualization.DataTable(jdata);
var chart = new google.visualization.PieChart(document.getElementById('piechart_div'));
chart.draw(data, {is3D: true, title: 'Multi Routes per Lane', width: 600, height: 440});
}
</script>
</head>
<body>
<input type="button" onclick = "drawChart()" value="test">
<div id="piechart_div"> </div>
</body>
</html>

add the success handler in the ajax call. Also as Felix King pointed out, google.visualization.DataTable expects an JavaScript Object - not a string
So move all this code
var jdata = '{ "cols": [{"id":"", "label":"lane", "type": "string"},' + '{"id": "", "label": "routes", "type": "number"}],' + '"rows":[{"c": [{"v":' + json.hits[0].hits[0]._source.lane + '},{"v":' + json.hits[0].hits[0]._source.routes + '}]}]';
var data = new google.visualization.DataTable(jdata);
var chart = new google.visualization.PieChart(document.getElementById('piechart_div'));
chart.draw(data, {is3D: true, title: 'Multi Routes per Lane', width: 600, height: 440});
into the success handler
$.ajax({
url: 'http://localhost:9200/wcs/routes/_search?pretty=true'
, type: 'POST'
, data :
JSON.stringify(
{
"query" : { "match_all" : {} }
})
, dataType : 'json'
, success : function (json){ // <-- json = javascript object since you set dataType to 'json'
// your object to pass to DataTable
var jdata = {
"cols": [{
"id": "",
"label": "lane",
"type": "string"
}, {
"id": "",
"label": "routes",
"type": "number"
}],
"rows": [{
"c": [{
"v": json.hits[0].hits[0]._source.lane
}, {
"v": json.hits[0].hits[0]._source.routes
}]
}]
};
var data = new google.visualization.DataTable(jdata);
var chart = new google.visualization.PieChart(document.getElementById('piechart_div'));
chart.draw(data, {is3D: true, title: 'Multi Routes per Lane', width: 600, height: 440});
}
});

Was able to do this with the following code (thanks dinjas):
var json;
$.ajax({
url: 'http://localhost:9200/wcs/routes/_search',
type: 'POST',
data :
JSON.stringify(
{
"query" : { "match_all" : {} }
}),
dataType : 'json',
async: false,
success: function(data){
json = data;
}
})
var jdata = {};
jdata.cols = [
{
"id": "",
"label": "Lane",
"type": "string"
},
{
"id": "",
"label": "Routes",
"type":"number"
}
];
jdata.rows = [
{
"c": [
{
"v": json.hits.hits[0]._source.lane
},
{
"v": json.hits.hits[0]._source.routes
}
]
}
];

data manipulation in javascript

i have an array of information containing folders like this:
[
{
"ACLID" : 0,
"ID" : 100,
"auditInfoVersion" : 3435973836,
"createBy" : 2,
"createDate" : "04/12/2012 17:38:46",
"isSubFolder" : 0,
"name" : "Piyush1",
"objectType" : 3,
-->"parentID" : 3,
"policyID" : 2,
"sDescription" : "",
"updateBy" : 2,
"updateDate" : "04/12/2012 17:38:46"
},
{
"ACLID" : 0,
"ID" : 102,
"auditInfoVersion" : 3435973836,
"createBy" : 2,
"createDate" : "05/10/2012 12:38:25",
"isSubFolder" : 0,

"auditInfoVersion" : 3435973836,
"createBy" : 2,
"createDate" : "05/14/2012 18:00:22",
"isSubFolder" : 0,
"name" : "SegFolderWithDiffPolicy",
"objectType" : 3,
-->"parentID" : 3,
"policyID" : 39,
"sDescription" : "",
"updateBy" : 2,
"updateDate" : "05/14/2012 18:00:22"
},
{
"ACLID" : 0,
"ID" : 104,
"auditInfoVersion" : 3435973836,
"createBy" : 2,
"createDate" : "05/17/2012 14:13:56",
"isSubFolder" : 0,
"name" : "New1",
"objectType" : 3,
-->"parentID" : 100,
"policyID" : 2,
"sDescription" : "",
"updateBy" : 2,
"updateDate" : "05/17/2012 14:13:56"
},
{
"ACLID" : 0,
"ID" : 105,
"auditInfoVersion" : 3435973836,
"createBy" : 2,
"createDate" : "05/17/2012 14:14:13",
"isSubFolder" : 0,
"name" : "abcasdna",
"objectType" : 3,
-->"parentID" : 104,
"policyID" : 2,
"sDescription" : "",
"updateBy" : 2,
"updateDate" : "05/17/2012 14:14:13"
},
{
"ACLID" : 0,
"ID" : 106,
"auditInfoVersion" : 3435973836,
"createBy" : 2,
"createDate" : "05/18/2012 12:51:39",
"isSubFolder" : 0,
"name" : "new2",
"objectType" : 3,

"policyID" : 2,
"sDescription" : "",
"updateBy" : 2,
"updateDate" : "05/18/2012 12:51:39"
}
]
now the required type of data is:
[{
name:'Piyush1',
children: [{
name: 'New1',
children:[{
name: 'abcasdna'
}]
},{
name: 'New2'
}]
},{
name: 'New'
}]
Now the thing is that there could be any number of folders and any level of hierarchy.
so is there a way i can achieve this conversion?

MongoDB query AND/OR Precedent

In MongoDB, if I wanted to express A AND (B OR C), I can easily do by:
db.demo.find( { a: 1, $or: [ {b:1}, {c:1} ] });
But if I wanted (A AND B) OR C -- it does not seem to work. If I try:
db.demo.find( { $or: [ {a:1,b:1}, {c:1} ] });
the above is treating it as A or B or C, which is same as
db.demo.find( { $or: [ {a:1}, {b:1}, {c:1} ] });
At this point in time, I do not want to use Javascript expression $where to accomplish this (but will have no choice, if nothing else works) - the reason being, I am creating a general filter rules, which is being directly converted as MongoDB query.
Any help?

The query works actually, exactly as it should. The question is incorrect.
Here is what a view of what I tried and how it works!
Data:
> db.demo.find()
{ "_id" : 1, "age" : 38, "mgmt" : "no", "salary" : 100 }
{ "_id" : 2, "age" : 45, "salary" : 200, "mgmt" : "no" }
{ "_id" : 3, "age" : 50, "salary" : 250, "mgmt" : "no" }
{ "_id" : 4, "age" : 51, "salary" : 75, "mgmt" : "yes" }
{ "_id" : 5, "age" : 45, "salary" : 75, "mgmt" : "no" }
Query to get (Age>40 AND Salary>200) OR mgmt='yes'
> db.demo.find( { $or: [ { age: {$gt:40}, salary:{$gt:200} }, {mgmt: 'yes'} ] })
{ "_id" : 3, "age" : 50, "salary" : 250, "mgmt" : "no" }
{ "_id" : 4, "age" : 51, "salary" : 75, "mgmt" : "yes" }
Query to get (Age>40) OR (Salary>200) OR mgmt='yes'
> db.demo.find( { $or: [ { age: {$gt:40}}, {salary:{$gt:201} }, {mgmt: 'yes'} ] })
{ "_id" : 2, "age" : 45, "salary" : 200, "mgmt" : "no" }
{ "_id" : 3, "age" : 50, "salary" : 250, "mgmt" : "no" }
{ "_id" : 4, "age" : 51, "salary" : 75, "mgmt" : "yes" }
{ "_id" : 5, "age" : 45, "salary" : 75, "mgmt" : "no" }
All of them working as it should. Great!
