Cannot grab the follower count from the following URL. Shows up as blank. Am I grabbing the right parameters?
https://developer.foursquare.com/docs/explore#req=pages/search%3Fname%3DNintendo
function foursquareFriends(url) {
var responses = UrlFetchApp.fetch(url);
var json = responses.getContentText();
var data = JSON.parse(json);
var likes = data.response.results.followers.count;
return likes;
}
You should do this (using this)
data.response.results[0].followers.count;
(And of course if you have more than 1 value - you should iterate).

I have two var's
var a = result.master_id;
var b = result.session_name;
i want to create a json string to pass to ajax. i tried this
var userData = {'pid':a,'session' :b};
i'm storing this userData in a sessionStorage and sending to ajax . but i'm getting pid undefined error.
is this the right way to do this?
any help is appreciated.
regards,
newbie
You are using the right code to store into variable. Try to console variable to identify.
Example code given below:
let result = {
master_id: 1,
session_name: "Hardik"
}
var a = result.master_id;
var b = result.session_name;
var userData = {'pid':a,'session' :b};
console.log(userData);
I have List of items data and empty array quotations :
var data = {};
var quotations = [];
I want to fill quotations with data values ,Every time i add new data it added successfully but all data values get last value .
for example :
$("#addquotation").click(function () {
debugger;
var itemname = $("#itemname").val();
var cost =parseFloat( $("#cost").val());
var notes = $("#notes").val();
var date = $("#date").val();
data.Item = itemname;
data.Cost = cost;
data.Notes = notes;
data.Date = date;
quotations.push(data);
)};
for first time i add
"test,45,testnotes,2016-02-03" Second time i 've added
"test2,45.2,testnotes2,2016-02-05"
when i debug i get data as :
obj(0): "test2,45.2,testnotes2,2016-02-05"
obj(1):"test2,45.2,testnotes2,2016-02-05"
it seems it append last version to all data
Please Advice . Thanks
You need to declare data inside the click handler, if it's declared as a global variable you are basically always modifying and adding the same data object to the array:
var quotations = [];
$("#addquotation").click(function () {
debugger;
var data = {};
var itemname = $("#itemname").val();
var cost =parseFloat( $("#cost").val());
var notes = $("#notes").val();
var date = $("#date").val();
data.Item = itemname;
data.Cost = cost;
data.Notes = notes;
data.Date = date;
quotations.push(data);
)};
You are pushing the same object reference each time since you declared data outside of the click handler.
Change from :
var data={};
$("#addquotation").click(function () {
To
$("#addquotation").click(function () {
var data={};// declare local variable
The problem is that data is a global variable and you add a reference to data to quotations.
When the first value is pushed to quotations, data and quotations[0] refer to the same object. Here is an example of what is happening:
var a = {num: 1};
var b = a;
b.num = 2;
console.log(a.num); // prints 2
The same thing happens when an object is pushed to an array. quotations does not contain a copy of data, it contains a reference to data so that modifying data also modifies quotations. To fix this, each element of quotations must refer to a different data object. This can be accomplished by defining data inside of the function instead of outside.
Replace
var data = {};
$("#addquotation").click(function() {
// populate data, push to quotations
});
with
$("#addquotation").click(function() {
var data = {};
// populate data, push to quotations
});
how can i get the first "id_miembro" for example of this:
{"actividades":[{"id_miembro":"V-005","id_dpto":"AC-04","id_actividad":"D-01","id_seccion":"S-03"},{"id_miembro":"V-005","id_dpto":"AC-02","id_actividad":"D-01","id_seccion":"S-01"}]}
I've tried with other ways but nothing, thanks.
Parsing a JSON string in javascript can be done with JSON.parse(). For your JSON you can do this to get the id_miembro of the first item in the list.
var json = '{"actividades":[{"id_miembro":"V-005","id_dpto":"AC-04","id_actividad":"D-01","id_seccion":"S-03"},{"id_miembro":"V-005","id_dpto":"AC-02","id_actividad":"D-01","id_seccion":"S-01"}]}';
var obj = JSON.parse(json);
var actividades = obj.actividades;
var first = actividades[0];
var id_miembro = first.id_miembro;
I broke it down into seperate variables so it's easier to follow which line does what.
If your data is alread a javascript object you can skip the first two lines and just do this
var obj = {"actividades":[{"id_miembro":"V-005","id_dpto":"AC-04","id_actividad":"D-01","id_seccion":"S-03"},{"id_miembro":"V-005","id_dpto":"AC-02","id_actividad":"D-01","id_seccion":"S-01"}]};
var actividades = obj.actividades;
var first = actividades[0];
var id_miembro = first.id_miembro;
I'm having a little problem here, i have an array like this:
function crearObjetos()
{
var palabraPeso = "peso";
var palabraFecha = "Fecha";
var localStorageKey000 = "objetosPesoFecha";
var contador = 0;
var pesoFecha = new Array(); //THE ARRAY
while(contador < 365)
{
var nuevoObjeto = new Object;
var fechaActual = new Date();
nuevoObjeto.peso = 0;
nuevoObjeto.fecha = fechaActual;
nuevoObjeto.id = contador;
pesoFecha[contador] = nuevoObjeto; //SAVE OBJECTs IN THE ARRAY
contador = contador +1;
}
if (Modernizr.localstorage)
{
localStorage.setItem(localStorageKey000, pesoFecha); //STORAGE THE ARRAY
}
}
The problem is that, when i try to load the array in local storage, i can't acces any data, all are "undefined" and i don't know why... Here is how i load the data from the array (in this case only the first objetc):
function damePrimerObjetoPesoFecha()
{
//LOAD THE ARRAY FROM LOCAL STORAGE
var localStorageKey000 = "objetosPesoFecha";
var arrayDeObjetos = localStorage.getItem(localStorageKey000);
//CHECK IN AN ALERT IF THE DATA IS OK
alert("El primero que devuelve"+arrayDeObjetos[0].id);
//RETURN THE FIRSTONE
return arrayDeObjetos[0];
}
An array can't be pushed into localStorage just like how it is. You have to use JSON.stringify on it. This line :
localStorage.setItem(localStorageKey000, pesoFecha);
must be changed to
localStorage.setItem(localStorageKey000, JSON.stringify(pesoFecha));
Similarly, when you're retrieving it from localStorage, you must use JSON.parse on it to convert it back to JSON. This line :
var arrayDeObjetos = localStorage.getItem(localStorageKey000);
must be :
var arrayDeObjetos = JSON.parse(localStorage.getItem(localStorageKey000));
Now when you access the first data, you wont get undefined.
Another alternative to this would be jStorage plugin which is wrapper around localStorage. It will take all the parsing problems from you and do it by itself if you pass an array or object to it.
Hope this helps!
localStorage only stores data as string.
You can strinify your array into JSON and save that and then parse it back when you load it
localStorage.setItem(localStorageKey000, JSON.stringify(pesoFecha)); //STORAGE THE ARRAY
var arrayDeObjetos = JSON.parse(localStorage.getItem(localStorageKey000));
LocalStorage can store strings only. You also need to remember that JSON.stringify converts date objects to string, so when deserializing via JSON.parse you need to manually create date for each object from array based on that string.
Firstly:
localStorage.setItem(localStorageKey000, JSON.stringify(pesoFecha));
and then
var arrayDeObjetos = JSON.parse(localStorage.getItem(localStorageKey000));
arrayDeObjetos.forEach(function(objecto){
objecto.fecha = new Date(objecto.fecha );
})
localstorage can only store strings.
If you want to store arrays & objects, you should convert them to JSON.
Here's a small helper:
var LS = {
set: function (key, val) {
return localStorage.setItem(key, JSON.stringify(val));
},
get: function (key) {
return JSON.parse( localStorage.getItem(key) );
}
};
Use it as follows:
// Store the array:
LS.set(localStorageKey000, pesoFecha);
// Retrieve the array:
var arrayDeObjetos = LS.get(localStorageKey000);
Here's the fiddle: http://jsfiddle.net/KkgXU/
I have an array:
var pages = new Array();
I want to push my pages data to this array like this:
$('li.page').each(function () {
var datatype = $(this).attr('data-type');
var info = $(this).attr('data-info');
pages_order.push({datatype:info});
});
but this code doesn't replace datatype as variable, just puts datatype string as a key.
How do I make it place there actual string value as a key name?
I finally saw what you were trying to do:
var pages = new Array();
$('li.page').each(function () {
var datatype = $(this).attr('data-type');
var info = $(this).attr('data-info');
var temp = {};
temp[datatype] = info;
pages_order.push(temp);
});
$('li.page').each(function () {
//get type and info, then setup an object to push onto the array
var datatype = $(this).attr('data-type'),
info = $(this).attr('data-info'),
obj = {};
//now set the index and the value for the object
obj[datatype] = info;
pages_order.push(obj);
});
Notice that you can put a comma between variable declarations rather than reusing the var keyword.
It looks like you just want to store two pieces of information for each page. You can do that by pushing an array instead of an object:
pages_order.push([datatype, info]);
You have to use datatype in a context where it will be evaluated.
Like so.
var pages = [];
$('li.page').each(function () {
var datatype = $(this).attr('data-type'),
info = $(this).attr('data-info'),
record = {};
record[datatype] = info;
pages_order.push(record);
});
You only need one var it can be followed by multiple assignments that are separated by ,.
No need to use new Array just use the array literal []
You may add below single line to push value with key:
pages_order.yourkey = value;
