Any help would be appreciate. I need to create a slider based on JSON datas from the moviedb API. I created the slider showing the title, the picture and the description within a for loop but the last thing I need to achieve is to get the movie rating but instead of the number I need to show stars (half or full filled according to the datas provided).
I'm stuck and tried different things but it doesn't work. I know it's quite simple but I'm stuck.
Many thanks for any help. Do not hesitate if you need something else because it's my first post on stackoverflow.
Here is the fiddle of my work :
https://jsfiddle.net/y2hbzej8/7/
Here is my JS code to get datas :
JS :
var urlmoviedb = 'https://api.themoviedb.org/3/movie/upcoming?api_key=e082a5c50ed38ae74299db1d0eb822fe';
$(function() {
$.getJSON(urlmoviedb, function (data) {
console.log(data);
for (var x = 0; x < data.results.length; x++) {
var title = data.results[x].original_title;
var descr = data.results[x].overview;
var note = data.results[x].vote_average;
var noteround = Math.round(2 * note) / 2;
var str = "/jj8qgyrfQ12ZLZSY1PEbA3FRkfY.jpg";
var imageurl = str.replace("/jj8qgyrfQ12ZLZSY1PEbA3FRkfY.jpg", "https://image.tmdb.org/t/p/w1280");
var image = imageurl + data.results[x].backdrop_path;
$('#image').append('<li>' + '<h2 class="h2-like mt-4">' + title + '</h2>' + '<p class="note">' + noteround + '</p>' + "<img class='img-fluid mb-4' src='" + image + "'>" + '<p class="descr">' + descr + '</p>' + '</li>');
}
});
Divide the vote_average field of each row by two since values go from 0 to 10. This will give you five stars based values.
I edited your example, I added font-awesome CSS library that will give you lots and lots of icons you can play with. Check them out
Here's the edited example on JSFiddle
var urlmoviedb = 'https://api.themoviedb.org/3/movie/upcoming?api_key=e082a5c50ed38ae74299db1d0eb822fe';
$(function() {
$.getJSON(urlmoviedb, function(data) {
console.log(data);
for (var x = 0; x < data.results.length; x++) {
var title = data.results[x].original_title;
var descr = data.results[x].overview;
var note = data.results[x].vote_average;
var noteround = Math.round(2 * note) / 2;
var str = "/jj8qgyrfQ12ZLZSY1PEbA3FRkfY.jpg";
var imageurl = str.replace("/jj8qgyrfQ12ZLZSY1PEbA3FRkfY.jpg", "https://image.tmdb.org/t/p/w1280");
var image = imageurl + data.results[x].backdrop_path;
//Translate vote average field into number of stars by dividing them by two since vote_average goes from 0 to 10
var numberOfStars = Math.round(note/2);
var stars = '';
for(var index = 0; index < numberOfStars; index++)
stars += '<span class="fa fa-star"/>';
$('#image').append('<li>' + '<h2 class="h2-like mt-4">' + title + '</h2>' + "<img class='img-fluid mb-4' src='" + image + "'>" + '<p class="descr">' + descr + '</p>' + stars + '</li>');
}
});

I am trying to get indVars to repeat for the amount of times that numInd requires. So if numInd = 3 then I'm wanting something similar to this indVars[0] = divStart + userEntryVars + divEnd -- indVars[1] = divStart + userEntryVars + divEnd ... and so on for however many numInd dictates --- Then the arrays get posted to innerHTML.
/*User Selection Of Indicators*/
var numInd = 3 /*This is amount of indicators that should show in innerHTML.*/
/*User Entry Variables Per Selection*/
var uHeight = 120
var uWidth = 225
/*Html Variables*/
var divStart = '<div class="col-sm-auto">'
var userEntryVars = '<img src="whatever.jpg" style="height:' + uHeight +'px; width: '+ uWidth + 'px">'
var divEnd = '</div>'
/*Div InnerHTML*/
var divArea = document.getElementById("IndicatorArea") ;
var out = []
var indVars = [divStart + userEntryVars + divEnd] ;
/*Loop For Number Of Indicators*/
for (i = 0; i < numInd; i++){
out.push(indVars[i])
};
console.log(out[0]) /*Returns Data I Expect*/
console.log(out[1]) /*Returns Data I Don't Expect, It Should Be Showing Same as out[0]*/
divArea.InnerHTML = indVars
So the user selects the amount of indicators that should show (indicators = boxes), then they can type in the variables that go into the innerHTML...so if they select 2, the user has to fill in 2 of the user entries for each variable because the indicators will show different data. I have tried a few variations of arrays and I have gotten close but sometimes I'm getting "undefined" and then the div counts. I'm thinking the HTML Variables should be in a for loop to loop for the number of indicators but I'm not sure. Ultimately, the number of selected indicators should be 3 different entities, and within these 3 different entities can be variable data posted by the user. Thank you in advance.
for indVars, right now you're adding together divStart + userEntryVars + divEnd.
If you want indVars[0] = divStart and indVars[1] = userEntryVars, declare it like
var indVars = [divStart, userEntryVars, divEnd]
I was able to resolve this by the following code.
/*User Selection Of Indicators*/
var numInd = 3 /*This is amount of indicators that should show in innerHTML.*/
/*User Entry Variables Per Selection*/
var uHeight = 120
var uWidth = 225
/*Html Variables*/
var divStart = '<div class="col-sm-auto">'
var userEntryVars = '<img src="whatever.jpg" style="height:' + uHeight +'px; width: '+ uWidth + 'px">'
var divEnd = '</div>'
/*Div InnerHTML*/
var divArea = document.getElementById("IndicatorArea") ;
var out = []
var indVars = divStart + userEntryVars + divEnd ;
/*Loop For Number Of Indicators*/
for (i = 0; i < numInd; i++){
out.push(indVars)
};
divArea.InnerHTML = out.join("")
I have looked at other Questions of this type and none of them solved my problem. I am having this JavaScript code:
var count1;
for (count1 = 1; count1 < 11; count1++) {
var article = res.articles[count1]
var ImageURL = res.articles[count1].urlToImage
$('#showNews').append('<div id="' + count1 + '" class="article"><div class="overlayart"><div class="art"><h3>' + article.title + '</h3 <p>' + article.description + '<br><br><button onclick="divLoad()">Follow Link</button></p></div></div></div>');
$("#" + count1).css('background-image', 'url(' + ImageURL + ')');
x = article.url;
}
function divLoad() {
alert(article.url);
};
Basically there are 10 items with different articles. Scopes of variables are all correct. I can see the links of the items when I console log them in the loop. I want to alert each URL whenever each Item is clicked for a respected button. But when I click that I get the error:
Uncaught ReferenceError: divLoad is not defined
at HTMLButtonElement.onclick
Am I missing something?
EDIT [My Full Code]:
var x;
function divLoad() {
alert(x);
};
$(document).ready(function(){
var url = 'https://newsapi.org/v2/top-headlines?country='+country+'&apiKey=MYAPIKEY';
$.getJSON(url).then(function(res){
//console.log(res)
var count1;
for(count1 = 1; count1 < 11; count1++){
var article = res.articles[count1]
var ImageURL = res.articles[count1].urlToImage
x = article.url;
$('#showNews').append('<div id="'+count1+'" class="article"><div class="overlayart"><div class="art"><h3>'+article.title+'</h3><p>'+article.description+'<br><br><button onclick="divLoad()">Follow Link</button></p></div></div></div>');
$("#"+count1).css('background-image','url(' + ImageURL + ')');
}
});
The problem is that you're always referencing one single, global variable. That variable (x) will only ever hold the last value it was set to in your for loop.
Instead, we can append the articles and give each one a data attribute - that way, we can associate each element with a specific article URL.
function divLoad(url) {
alert(url);
};
$(document).ready(function() {
var url = 'https://newsapi.org/v2/top-headlines?country=' + "test" + '&apiKey=MYAPIKEY';
$.getJSON(url).then(function(res) {
for (let count1 = 1; count1 < 11; count1++) {
let article = res.articles[count1];
$('#showNews').append('<div id="' + count1 + '" class="article"><div class="overlayart"><div class="art"><h3>' + article.title + '</h3><p>' + article.description + '<br><br><button class="article-btn">Follow Link</button></p></div></div></div>');
$("#" + count1)
.css("background-image", "url('" + article.urlToImage + "'")
.attr("data-url", article.url); //Associate the URL to the element
}
});
$("#showNews").on("click", ".article-btn", function() {
var url = $(this).closest(".article").attr("data-url"); //Get the associated URL
divLoad(url);
});
});
If you inspect the <div class="article"> now, you'll see each one has a data-url attribute that holds its URL.
Premise:
I'm playing around with javascript and have been trying to display a populated JSON file with an array of people on the browser. I've managed to display it through ajax, but now I'm trying to perform the same task with jQuery.
Problem:
The problem is that it keeps saying customerdata[i] is undefined and can't seem to figure out why.
$(function() {
console.log('Ready');
let tbody = $("#customertable tbody");
var customerdata = [];
$.getJSON("MOCK_DATA.json", function(data) {
customerdata.push(data);
});
for (var i = 0; i < 200; i++) {
//Cell for name
let nameTD = $('<td>').text(customerdata[i].first_name + ", " + customerdata[i].last_name);
//Cell for birthdate
let mDate = moment(customerdata[i].birthdate);
let formattedmDate = mDate.format('YYYY-MM-DD');
let birthdateTD = $('<td>').text(formattedmDate);
//Cell for Address
let addressTD = $('<td>').html("City: " + customerdata[i].city + '<br>' + "Email: " + customerdata[i].email + '<br>' + '<a href=' + customerdata[i].website + '>Website</a>');
//Cell for Credits
let creditTD = $('<td>').text(customerdata[i].credits);
let row = $('<tr>').append(nameTD).append(birthdateTD).append(addressTD).append(creditTD);
tbody.append(row);
}
})
SAMPLE CONTENT OF MOCK_DATA.json
[
{"id":1,"first_name":"Tracey","last_name":"Jansson","email":"tjansson0#discuz.net","gender":"Female","ip_address":"167.88.183.95","birthdate":"1999-08-25T17:24:23Z","website":"http://hello.com","city":"Medellín","credits":7471},
{"id":2,"first_name":"Elsa","last_name":"Tubbs","email":"etubbs1#uol.com.br","gender":"Female","ip_address":"61.26.221.132","birthdate":"1999-06-28T17:22:47Z","website":"http://hi.com","city":"At Taḩālif","credits":6514}
]
Firstly, you're pushing an array into an array, meaning you're a level deeper than you want to be when iterating over the data.
Secondly, $.getJSON is an asynchronous task. It's not complete, meaning customerdata isn't populated by the time your jQuery is trying to append the data.
You should wait for getJSON to resolve before you append, by chaining a then to your AJAX call.
$.getJSON("MOCK_DATA.json")
.then(function(customerdata){
for(var i = 0; i < 200; i++){
//Cell for name
let nameTD = $('<td>').text(customerdata[i].first_name + ", " + customerdata[i].last_name);
//Cell for birthdate
let mDate = moment(customerdata[i].birthdate);
let formattedmDate = mDate.format('YYYY-MM-DD');
let birthdateTD = $('<td>').text(formattedmDate);
//Cell for Address
let addressTD = $('<td>').html("City: " +
customerdata[i].city + '<br>' + "Email: " +
customerdata[i].email + '<br>' + '<a
href='+customerdata[i].website+'>Website</a>');
//Cell for Credits
let creditTD = $('<td>').text(customerdata[i].credits);
let row = $('<tr>').append(nameTD).append(birthdateTD).append(addressTD).append(creditTD);
tbody.append(row);
}
})
You also won't need to define customerdata as an empty array at all with this approach.
The problem is that data is already an array.
so you should use:
customerdata = data;
otherwhise you are creating an array in the pos 0 with all the data
In my Firefox OS app i use Flickr API to show relevant images, My URL for the call is like this.
https://api.flickr.com/services/rest/?method=flickr.photos.search&api_key=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx&lat=42.86366&lon=-75.91438&radius=3&format=json&nojsoncallback=1
and i use created a function to call the flicker api for the images. This is the function where i create the URL with the api key and latitude and longitude for the api call
function displayObject(id) {
console.log('In diaplayObject()');
var objectStore = db.transaction(dbTable).objectStore(dbTable);
objectStore.openCursor().onsuccess = function(event) {
var cursor = event.target.result;
if (cursor) {
if (cursor.value.ID == id) {
var lat = cursor.value.Lat;
var lon = cursor.value.Lon;
showPosOnMap (lat, lon);
// create the URL
var url = 'https://api.flickr.com/services/rest/?method=flickr.photos.search';
url += '&api_key=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx';
url += '&lat=' + lat + '';
url += '&lon=' + lon + '';
url += '&radius=3';
url += '&format=json&nojsoncallback=1';
$.getJSON(url, jsonFlickrFeed);
return;
}
cursor.continue();
} else {
$('#detailsTitle').html('No DATA');
}
};
}
This function gets the JSON object received from flickr. This function displays the thumbnails of the images in a jquery mobile grid.
function jsonFlickrFeed (data) {
console.log(data);
var output = '';
// http://farm{farmId}.staticflickr.com/{server-id}/{id}_{secret}{size}.jpg
for (var i = 0; i < data.photos.photo.length; i++) {
// generate thumbnail link
var linkThumb = '';
linkThumb += 'http://farm' + data.photos.photo[i].farm + '.staticflickr.com/' + data.photos.photo[i].server + '/' + data.photos.photo[i].id + '_' + data.photos.photo[i].secret + '_s.jpg';
// generate Full image link
var linkFull = '';
linkFull += 'http://farm' + data.photos.photo[i].farm + '.staticflickr.com/' + data.photos.photo[i].server + '/' + data.photos.photo[i].id + '_' + data.photos.photo[i].secret + '_b.jpg';
if (i < 20)
console.log(linkThumb);
//console.log(linkFull);
var title = data.photos.photo[i].title;
var blocktype = ((i % 3) == 2) ? 'c' : ((i % 3) == 1) ? 'b' : 'a';
output += '<div class="ui-block-' + blocktype + '">';
output += '<a href="#showphoto" data-transition="fade" onclick="showPhoto(\'' + linkFull + '\',\'' + title + '\')">';
output += '<img src="' + linkThumb + '_q.jpg" alt="' + title + '" />';
output += '</a>';
output += '</div>';
};
$('#photolist').html(output);
}
Then finally this function show the full screen view of the image. When the user taps on the thumbnail a larger image is taken and shown.
function showPhoto (link, title) {
var output = '<a href="#photos" data-transition="fade">';
output += '<img src="' + link + '_b.jpg" alt="' + title + '" />';
output += '</a>';
$('#myphoto').html(output);
}
My problem is that, i get the JSON object with the images by calling the API. i have console.log() where i output the json object and i checked all the image info is there. But when i go to the grid view and even the full view i get the default image that states that the This image or video is currently unavailable. I can't figure out what im doing wrong here.. Please help.
You may be requesting an image size that flickr does not have for that image. You are appending "_s", "_q" and "_b" to select a few sizes - so perhaps those are not available. You can check the flickr API 'photos.getSizes' to see what sizes are available. The Flickr API seems to be pretty inconvenient sometimes.

Okay, so let's say I have a textbox that you can enter something like
Sebastian Soria 3'|12' Digano
Nam Tae-Hee 23', 45'|33' Julio Vezbek
And that textarea does this upon focusing your mouse out of it, the texarea gets read line by line and each line looks for its delimeter "|" and then splits it up and divides that in home and away scorer.
Here's a JS fiddle: http://jsfiddle.net/cu24k/
I could easily do it so if it's above 10, to scrap the last 4 characters of " XX'" and 3 do " X'" and split that up and color/bold it. But then I realized, what if they scored more than once? It would be 23', 45' or longer!
So, I thought... what if I can just take apart any apostrophe, comma and number and color/bold that.
Is there a way?
I'm not 100% sure what you were trying to do, but I threw together what I think you were going for: http://jsfiddle.net/cu24k/1/
Here is the updated JS:
$(document).ready(function () {
$('.scorers').on('change', function () {
$("#home_scorers").text("");
$("#away_scorers").text("");
var lines = $('.scorers').val().split('\n');
for (var i = 0; i < lines.length; i++) {
var split = lines[i].split('|');
// get home data
var home = split[0];
var homeIndex = home.search( /\d+\'/ );
var homeTeam = home.substr( 0, homeIndex );
var homeScore = home.substr( homeIndex );
// get away data
var away = split[1];
var awayIndex = away.lastIndexOf( "'" ) + 1;
var awayScore = away.substr( 0, awayIndex );
var awayTeam = away.substr( awayIndex );
// output data
$("#home_scorers").append(
"<div>" + homeTeam +
"<b>" + homeScore + "</b>" +
"</div>");
$("#away_scorers").append(
"<div>" +
"<b>" + awayScore + "</b>" +
awayTeam + "</div>");
}
});
});
