Check if a array is contained in another - javascript

Im struggling with a piece of code i have below and cant seam to find something like it anywhere on stacks.
I have tried using the JavaScript .indexof(is returning all that doesn't contain variables) as well as the .match(shows all even if contain part of the word. i need it to be exact for obvious reasons) and even jquery.
I was wondering if anyone can help me.
I have a script that pulls data from the server into the following array.
from there i need to be able to compare this array with data that is on the page. if it exists in the server i want to highlight the checkbox i have created. when i did .match it found all variables that contained say the characters foo but i need exact matches not just if it contains.
see below for what i currently have. (note that the variables aren't set in stone and some may be different that will be contained in others which is why they need to be exact)
var industriesget = [ "Servers & Software", "Environmental Issues", "Hotels & Tourism"];
var industries = [ "Servers & Software", "Environmental Issues", "Hotels & Tourism", "Liquor, Wine & Beer", "Defense Industries", "Publishing & Printing", "Real Estate", "Not For Profit", "Food Services", "Corporate & Banking", "Agriculture & Fishing", "Communications", "Manufacturing", "Mining", "Entertainment & Gambling", "Retail Sales", "Signage & Fitouts", "Construction", "Transportation", "Public Utilities", "Education" ];
for ( var i = 0; i < industries.length; i++ ) {
//another for loop to run through the matches?
if..........
document.write( "<label for='" + industries[ i ] + "' class='col-md-2 col-xs-5' style=' float:left; height:55px;' valign='middle'>" + industries[ i ] + "<input valign='middle' type='checkbox' style='vertical-align: middle;text-align: center;' name='products' id='" + industries[ i ] + "' checked></label>" );
else{
document.write( "<label for='" + industries[ i ] + "' class='col-md-2 col-xs-5' style=' float:left; height:55px;' valign='middle'>" + industries[ i ] + "<input valign='middle' type='checkbox' style='vertical-align: middle;text-
}
}

Is this what you are looking for? This is simplest way.
var industriesget = [ "Servers & Software", "Environmental Issues", "Hotels & Tourism"];
var industries = [ "Servers & Software", "Environmental Issues", "Hotels & Tourism", "Liquor, Wine & Beer", "Defense Industries", "Publishing & Printing", "Real Estate", "Not For Profit", "Food Services", "Corporate & Banking", "Agriculture & Fishing", "Communications", "Manufacturing", "Mining", "Entertainment & Gambling", "Retail Sales", "Signage & Fitouts", "Construction", "Transportation", "Public Utilities", "Education" ];
for ( var i = 0; i < industries.length; i++ ) {
//another for loop to run through the matches?
if(industriesget.indexOf(industries[i])!== -1)
document.write( "<label for='" + industries[ i ] + "' class='col-md-2 col-xs-5' style=' float:left; height:55px;' valign='middle'>" + industries[ i ] + "<input valign='middle' type='checkbox' style='vertical-align: middle;text-align: center;' name='products' id='" + industries[ i ] + "' checked></label>" );
else{
document.write( "<label for='" + industries[ i ] + "' class='col-md-2 col-xs-5' style=' float:left; height:55px;' valign='middle'>" + industries[ i ] + "<input valign='middle' type='checkbox' style='vertical-align: middle;text-")
}
}
If you want to find whether industriesget is subset of industries, then try using
var intersectionIndustries = industries.filter(function(n) {
return industriesget.indexOf(n) !== -1;
});
and check
(intersectionIndustries.length == industriesget.length)
,if true then its subset, else there are non existent entries in industries get.

Use this:
pass two arrays to this function and check if the flag is true or not:
var industriesget = [ "Servers & Software", "Environmental
Issues", "Hotels & Tourism"];
var industries = [ "Servers & Software", "Environmental Issues", "Hotels
& Tourism", "Liquor, Wine & Beer", "Defense Industries", "Publishing &
Printing", "Real Estate", "Not For Profit", "Food Services", "Corporate &
Banking", "Agriculture & Fishing", "Communications", "Manufacturing",
"Mining", "Entertainment & Gambling", "Retail Sales", "Signage &
Fitouts",
"Construction", "Transportation", "Public Utilities", "Education" ];
if(arr(industriesget,industries)) {
alert("contains");
}
Where our function is:
function arr(industriesget,industries)
{
var flag=false;
for(var i=0;i<industriesget.length;i++)
{
if(industries.includes(industriesget[i])) {
flag = true;
}
}
return flag;
}

Not showing json parsed data in an unordered list

I have the following json file which I want to show as a list.
[
{
"shopName": "The Coffee Connection",
"address": "123 Lakeside Way",
"phone": "16503600708",
"prices": [
{
"Cafe Latte": 4.75,
"Flat White": 4.75,
"Cappucino": 3.85,
"Single Espresso": 2.05,
"Double Espresso": 3.75,
"Americano": 3.75,
"Cortado": 4.55,
"Tea": 3.65,
"Choc Mudcake": 6.40,
"Choc Mousse": 8.20,
"Affogato": 14.80,
"Tiramisu": 11.40,
"Blueberry Muffin": 4.05,
"Chocolate Chip Muffin": 4.05,
"Muffin Of The Day": 4.55
}
]
}
]
I want to iterate over the prices and show them in in a listView. I am using the the following Ajax function and function to extract this data. Unfortunately when I run my code I have an empty list.
$.ajax({
type: 'GET',
url: '/data/hipstercoffee.json',
success: function(data) {
// console.log('success', data);
let widget = show(data);
$("#Meals").html(widget);
}
});
and my other function is.
$.ajax({
type: 'GET',
url: '/data/hipstercoffee.json',
dataType:'json',
success: function(data) {
var data = JSON.parse(data)[0];
// console.log('success', data);
let widget = show(data);
$("#Meals").html(widget);
}
});
I am getting unexpected o at JSON at position 1 error.
Your prices is an array with a single element (object). So you need to process this object. Something like this.
var data = [{
"shopName": "The Coffee Connection",
"address": "123 Lakeside Way",
"phone": "16503600708",
"prices": [{
"Cafe Latte": 4.75,
"Flat White": 4.75,
"Cappucino": 3.85,
"Single Espresso": 2.05,
"Double Espresso": 3.75,
"Americano": 3.75,
"Cortado": 4.55,
"Tea": 3.65,
"Choc Mudcake": 6.40,
"Choc Mousse": 8.20,
"Affogato": 14.80,
"Tiramisu": 11.40,
"Blueberry Muffin": 4.05,
"Chocolate Chip Muffin": 4.05,
"Muffin Of The Day": 4.55
}]
}];
function show(data) {
var ul = '<ul>' +
Object.keys(data[0].prices[0]).map(function(key) {
return '<li>' + key + ': ' + data[0].prices[0][key] + '</li>';
}).join('') +
'</ul>';
$('#result').html(ul);
}
show(data); //for demonstration purpose
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="result">loading...</div>
JSON is a string. You have to decode the it first to turn it into a javascript object. Also notice that an array [] is wrapped around the actual data object.
var data = JSON.parse(data)[0];
Tip: When retrieving data, always output it first (console.log(data)) in your success message, to see how the data is structured. You will spot things like the array much faster that way. Once your code is working, remove the output.

Json, get info within another level

I have json code that comes out like:
{
"player": [{
"player_id": "1",
"player_name": "Maxfly",
"player_image": "res_573fc05f57c0e.png",
"player_background_image": "images/player_backgrounds/581046687fd89.jpg",
"player_info": "",
"player_region": "North America",
"player_teams": [{
"id": "1",
"team_name": "Test Team",
"team_link": "test-team"
}, {
"id": "65",
"team_name": "Test Team 2",
"team_link": "test-team-2"
}]
}]
}
I've managed to get the player_id and player_name etc. My question is how to I just get the teams? I've tried the following:
$.getJSON("jsonlink",
function(data) {
$.each(data.player.player_teams, function(i,player_team){
var append_data = "<div class='item team_item'><div class='row'><div class='col col_img'><a href='/t/" + player_team.team_name + "' ></a></div></div></div>";
$("#popin-container").append($('<div>' + append_data + '</div>').hide().fadeIn(800));
});
});
Trying to figure out what I'm doing wrong. Is my json object correct?
Thanks!
Your data.player.player_teams is wrong, as data.player is an array, and not an object. You need to loop through it, or in simple way, you need to attach a [0] like this:
$.each(data.player[0].player_teams, function(i, player_team) {

Using each in PHP like jquery

I'm used to using jQuery's each to go through an array and now I need to do the same in PHP, but I'm not quite sure how. PHP's each doesn't work quite the same way.
Given the following array, I know in jquery I could do something like the following to get the id value from each of the entry fields:
$.each(obj.entry, function(i, data) {
console.log(data.id);
});
The question I have is how to do this same thing in PHP. I tried:
//code to generate `$json` up here
echo $json; //returns array shown below
$newarray =json_decode($json, true);
$broke = each($newarray);
What do I need to do differently to get all the id from all the entries? Assume there will be around 100 or so.
Example JSON object below:

foreach($newarray as $key => $value) {
echo $key; // 0, 1, 2, etc
echo $value['id'] ; // echos ID
}
As your JSON String represents an object I would leave it as an object i.e. loose the ,true in the json_decode()
$jObj = json_decode($json);
foreach( $jObj->entry as $entry ) {
echo $entry->id . PHP_EOL;
echo $entry->title . PHP_EOL;
echo $entry->updated . PHP_EOL;
}
To make a new object out of what you take from the original data you coudl do something like this
$jObj = json_decode($json);
$new = new stdClass(); // create a new object
foreach( $jObj->entry as $entry ) {
$t = new stdClass();
$t->id = $entry->id;
$t->title = $entry->title;
$t->updated = $entry->updated;
$new->entries[] = $t; // create an array of objects
}
$newJsonString = json_encode($new);
PHP has foreach for this kind of operation
foreach($data as $key=> $value){
echo $value['id'];// or whatever you need
}
You can use php foreach loop:
foreach($newarray as $key => $value) {
// do smthg here
}
You can use for and foreach statements.
$row = json_decode($jsonString);
foreach($row as $key => $value) {
echo $key, '=>', $value;
// for you in $value will be key id $value['id']
}

Fill tree json data to dropdown box

I have json data in tree format:
[
{
"beer_names": [
"Apple Ale",
"Bad Seed Pumpkin Ale"
],
"brewery": "Basil T's Brew Pub and Italian Grill"
},
{
"beer_names": [
"5 C's IPA",
"Bottle Rocket IPA",
"Kate The Great Russian Imperial Stout",
"Wheat Wine"
],
"brewery": "Portsmouth Brewery"
},
{
"beer_names": [
"Black Forest Dunkelweizen",
"Equinox E.S.B.",
"Evolutionary IPA",
"G.E. Lite",
"Nut Brown",
"Red",
"Smoked Porter"
],
"brewery": "Glen Ellyn Sports Brew"
}
]
So I want to fill this data to Dropdown box like this:
--Basil T's Brew Pub and Italian Grill
--------Apple Ale
--------Bad Seed Pumpkin Ale
--Portsmouth Brewery
--------5 C's IPA
--------Bottle Rocket IPA
--------Wheat Wine
--------Kate The Great Russian Imperial Stout
--Glen Ellyn Sports Brew
--------Black Forest Dunkelweizen
--------Equinox E.S.B.
--------Evolutionary IPA
--------G.E. Lite
--------Nut Brown
--------Red
--------Smoked Porter
Or a tree view allow for select value name of child equipment?
Here you are:
var data = [{
"beer_names": [
"Apple Ale",
"Bad Seed Pumpkin Ale"
],
"brewery": "Basil T's Brew Pub and Italian Grill"
}, {
"beer_names": [
"5 C's IPA",
"Bottle Rocket IPA",
"Kate The Great Russian Imperial Stout",
"Wheat Wine"
],
"brewery": "Portsmouth Brewery"
}, {
"beer_names": [
"Black Forest Dunkelweizen",
"Equinox E.S.B.",
"Evolutionary IPA",
"G.E. Lite",
"Nut Brown",
"Red",
"Smoked Porter"
],
"brewery": "Glen Ellyn Sports Brew"
}];
$.each(data, function(index, value) {
var str = '<optgroup label="' + value["brewery"] + '">';
$.each(value['beer_names'], function(index, value) {
str += '<option value="' + value + '">' + value + '</option>';
});
str += '</select>';
$('select').append(str);
});

Javascript Search Nested Object with Regex

I have this:
var foo = {
"Category1": [
{"Company1": {"URL": ["DomainName1", "DomainName2"]}},
...
],
...
}
Normally, I would access the DomainName1 like this:
foo["Category1"][0]["Company1"]["URL"][0]
However, I want to search all of foo for a certain DomainName, and I don't know any other information. I know that I could use several nested for loops, but that is very, very slow. What is an efficient way to do this? I was thinking of something along the lines of a '*' in place of ["Category1"], [0], etc. but I don't know how to do that.
Any help would be greatly appreciated.
My answer may be opinionated however still... With tens of thousands objects you're trying to re-invent the wheel. This is an exact candidate for a database storage. Either SQL or non-SQL like MongoDB.
This is a good problem to solve it using Jsonpath.
For instance, you can use this expression to look for all URL:
var out = jsonPath(json, "$..URL[*]").toJSONString() + "\n";
document.write(out);
You can use an expression to match the domain you want.
For your case, you can use this expression:
$..URL[?(#.indexOf('DomainName1') != -1)]
