Just learning javascript & html.
I am trying to get a value from some jsonp. This is what is being returned
detail( {
"StatusCode": 0,
"StatusInfo": "Processed and Logged OK",
"PageNumber": 1,
"TotalPageCount": 1,
"TotalProductCount": 1,
"PageProductCount": 1,

"ProductId": "255163145",
"ProductType": "QuantityOnlyProduct",
"UnitPrice": 0.575,
"UnitType": "100g"
}
]
} )
My code is as follows:
<!DOCTYPE HTML>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<title>Tesco JSONP</title>
</head>
<body>
<button id="detail">detail</button>
<script type="text/javascript">
function detail(data) {
document.getElementById('name').innerHTML = (data.Products.Name)
}
function data() {
var script_elem = document.createElement('script'),
url = "http://www.techfortesco.com/groceryapi_b1/restservice.aspx?command=PRODUCTSEARCH&JSONP=detail&searchtext=5010204736716&page=1&sessionkey=123456789"
script_elem.setAttribute('src', url);
document.head.appendChild(script_elem);
}
document.getElementById('detail').addEventListener('click', data, false);
</script>
<div id="name"></div>
</body>
</html>
When run I am getting undefined. I'm guessing that my syntax (data.Products.Name) is incorrect. If I try (data.StatusCode) then I get the correct result.
Can someone please advise.
Best wishes.
data.Products is an array.
You need to specify which element you want to acess in the array.
In this case you only have one element, so the correct syntax would be data.Products[0].name

I created a project and I'm trying to add gogocartoJs in it.
The project works but the map is not showing.
I tried with the guides I found in the site, it looks plain and easy, but there is an step that I'm not understanding (please dont just copy/paste a piece of the site like it was obvious what it is the mistake, because it is not for me)

<div id="gogocarto"></div>

<script>
$(document).ready(function() {
carto = goGoCarto("#gogocarto", {
data: {
taxonomy: taxonomy,

}
});
});
</script>

I expect the map to show, and it doesnt
I added the project to github to show better
https://github.com/Aredros/testGogo/tree/master/dist
elements & taxonomy are js variables containing data you must provide according to the format described in the documentation.
// taxonomy
let taxonomy = {
"options":[
{
"id": "eu1",
"name":"Belgium",
"color":"#9acd32",
"icon":"fa-solid fa-building"
},
{
"id": "eu2",
"name": "Netherland",
"color": "#ffa500",
"icon": "fa-solid fa-fan"
},
{
"id": "eu3",
"name": "Luxembourg",
"color": "#a52a2a",
"icon": "fa-solid fa-money-bill-1"
}
]
}
The only missing info in the documentation is the id key in the taxonomy which must be referenced in your elements source dataset.
// elements
let elements = [
{
"title": "Brussels",
"geo": {
"latitude":50.84,
"longitude":4.34
},
"taxonomy": [ "eu1" ],
},
{
"title": "Namur",
"geo": {
"latitude":50.45,
"longitude":4.88
},
"taxonomy": [ "eu1" ],
},
{
"title": "Liege",
"geo": {
"latitude":50.62,
"longitude":5.60
},
"taxonomy": [ "eu1" ],
},
{
"title": "Rotterdam",
"geo": {
"latitude":51.88,
"longitude":4.51
},
"taxonomy": [ "eu2" ],
},
{
"title": "Amsterdam",
"geo": {
"latitude":52.07,
"longitude":5.12
},
"taxonomy": [ "eu2" ],
},
]
Idealy you should build an API returning taxonomy classification & elements data. Then perform ajax call in your html page.
$.ajax({
type: 'GET',
url: '/ajax/url_to_get_elements',
dataType: 'json',
success: function(elements, status) {
build_map(elements);
}
});
// build map = function with 1 arguments (elements) where you put the call to goGoCarto and options...
You can define more than 1 taxonomy group (Example above is about English countries) with the name you want => Cfr. Advanced Taxonomy with Categories. Your elements can then have multiple taxonomy reference listed [ "eu1", "week22", 14 ]. Items in the list can be Integer or String. The only important thing is the ID key and the taxonomy order! Keep the same order in your taxonomy than in your key "taxonomy": in your elements data sources!
Point of attention
Because the library is highly configurable with options, colors and icons it is important to put all your <scripts> tags inside <head> tags of your html page!
I have a remote page, below shows its source code,
<!DOCTYPE html>
<html>
<head>
<title>somethingg blabla</title>
</head>
<body>
<script type="text/javascript">
function blala( ) { /*** code **/ }
var sitedata = {
"count": 1,
"threads": {
"38752": {
"thread_id": 38752,
"node_id": 4,
"title": "The ShadyCraft Beta Launch!",
"prefix_id": 19,
"content": {
"count": 1,
"content": {
"226167": {
"post_id": 226167
}
}
}
}
}
};
var extra_codes_here = 'blabla';
</script>
<h1>Hello world</h1>
</body>
</html>
I have code for curl this page and i got this source code, but how to get the value var sitedata to php array ,
$doc; // your document
preg_match('/var\ssitedata\s=\s({.*});/s', $doc, $matches);
$json = $matches[1];
print_r(json_decode($json, true));
and your json is incorrect.
"post_id": 226167,
to
"post_id": 226167
I'm just starting to use javascript and json.
I need to read data (get Information function) from a json file when processing an event in a javascript function without using jquery or any other librery. I don't know if I am missing something in the code, or if I have to create an Request and handle the callback, or if I need to import additional javascript to use json. Because I don't know how to make it work. all i get is undefined. Any help is aprreciated.
The json file:
"hotels": [
{
"name": "Hotel Sunny Palms",
"imgUrl": "imgs/sunny.jpg",
"rating": 5,
"price": 108.00
},
{
"name": "Hotel Snowy Mountains",
"imgUrl": "imgs/snowy.jpg",
"rating": 4,
"price": 120.00
},
{
"name": "Hotel Windy Sails",
"imgUrl": "imgs/windy.jpg",
"rating": 3,
"price": 110.00
},
{
"name": "Hotel Middle of Nowhere",
"imgUrl": "imgs/nowhere.jpg",
"rating": 4,
"price": 199.00
}
]
my javascript is
function hot1(){
var text = '{"hotels": [{"name": "Hotel Sunny Palms","imgUrl": "http://www.pruebaswebludiana.xyz/imgs/sunny.jpg","rating": 5,"price": 108.00}]}';
var obj = JSON.parse(text);
document.getElementById("img-container").innerHTML =
obj.imagUrl+ "<br>"+ obj.name+ " " +obj.rating+ " " +obj.price;}
and my html code is
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=2" />
<link rel='stylesheet' href='style.css' type='text/css' media='all' />
</head>
<body>
<nav></nav>
<div class="container">
<div>
<ul>
<li onclick="hot1()">Hotel Sunny Palms</li>
<li onclick="hot2()">Hotel Snowy Mountains</li>
<li onclick="hot3()">Hotel Windy Sails</li>
<li onclick="hot4()">Hotel Middle Of Nowhere</li>
</ul>
</div>
<div class="banner-section" id="img-container">
</div>
</body>
</html>
Your JSON file contains an array in the property hotels, you probably need to work with one of those, e.g.:
var jsonText = ...;
var parsedObject = JSON.parse(jsonText);
var hotels = parsedObject.hotels;
var hotel = hotels[0]; // instead of 0, pass the index of the needed hotel
document.getElementById("img-container").innerHTML =
hotel.imgUrl + "<br/>" + hotel.name + " " + hotel.rating + " " + hotel.price;
{"hotels": [{"name": "Hotel Sunny Palms","imgUrl": "http://www.pruebaswebludiana.xyz/imgs/sunny.jpg","rating": 5,"price": 108.00}]}
You get undefined because you are trying to read the name (and other properties) of the outer object.
The outer object doesn't have those properties. It has one property: hotels.
The value of the property is an array.
That array contains an object.
The properties you are trying to access exist on that object.
i.e.
obj.hotels[0].name // etc
Here is the Live Example what I currently have now : https://dl.dropboxusercontent.com/u/11126587/input%20Tag%20Creation/tag.html
What I am wanting is that if I click on the "+ Add Another Segment" text it will Create same input box with same tag effect Like what currently have now(You can write Something and press the Enter To See the Tag Effect) .

It looks like you are trying to use Kendo Grid, which is a part of Kendo Web, but only have a reference to Kendo Mobile (i.e. kendo.mobile.min.js). You need to add a script reference to either kendo.web.min.js or kendo.all.min.js. Take a look at this jsfiddle, paying particular attention to the External Resource (i.e. kendo.all.min.js)
P.S. SO won't let me post a link to jsfiddle without some code, so here is part of the code again, to satisfy their requirements:
