Randomising Data in The Movie DB API

I am currently developing a Mobile App using the Movie DB API.
I have currently got the data pulling through but it's being hardcoded to bring up Spiderman from the Database.
Could anyone point me in the right direction? I have attached my code below :)
$(document).on('pageinit', '#home', function(){
// $(document).ready(function(){
console.info('hi');
var url = 'http://api.themoviedb.org/3/',
mode = 'search/movie?query=',
movieName = '&query='+encodeURI('Spiderman'),
key = '&api_key=7b0b1d8b1253e2bbfcd5602f76c52fdb';
$.ajax({
url: url + mode + key + movieName ,
dataType: "jsonp",
async: true,
success: function (result) {
console.dir(result);
ajax.parseJSONP(result);
},
error: function (request,error) {
alert('Network error has occurred please try again!');
}
});
});
$(document).on('pagebeforeshow', '#headline', function(){
$('#movie-data').empty();
$.each(movieInfo.result, function(i, row) {
if(row.id == movieInfo.id) {
$('#movie-data').append('<li><img src="http://image.tmdb.org/t/p/w92'+row.poster_path+'"></li>');
$('#movie-data').append('<li>Title: '+row.original_title+'</li>');
$('#movie-data').append('<li>Release date'+row.release_date+'</li>');
$('#movie-data').append('<li>Popularity : '+row.vote_average+'</li>');
$('#movie-data').listview('refresh');
}
});
});
$(document).on('vclick', '#movie-list li a', function(){
movieInfo.id = $(this).attr('data-id');
$.mobile.changePage( "#headline", { transition: "slide", changeHash: false });
});
var movieInfo = {
id : null,
result : null
}
var ajax = {
parseJSONP:function(result){
movieInfo.result = result.results;
$.each(result.results, function(i, row) {
console.log(JSON.stringify(row));
$('#movie-list').append('<li><a href="" data-id="' + row.id + '"><img src="http://image.tmdb.org/t/p/w92'+row.poster_path+'"/><h3>' + row.title + '</h3><p>')
})
}
}

Spiderman is being hardcoded into the Url here, so you need to obtain the search string, save it in a variable and replace the hardcoded spiderman:
var searchString = 'your_search_string'
var url = 'http://api.themoviedb.org/3/',
mode = 'search/movie?query=',
movieName = '&query='+encodeURI(searchString),
key = '&api_key=7b0b1d8b1253e2bbfcd5602f76c52fdb';
Also if you just want a list of movies not necessarily related to a search string you can try the discover endpoint of Movie DB API http://api.themoviedb.org/3/discover/movie.

Cannot POST more than one value with AJAX

I stucked on one thing. I have a 2 grid inside checkboxes. When I selected that checkboxes I want to POST that row data values like array or List. Actually when i send one list item it's posting without error but when i get more than one item it couldn't post values.
Example of my grid
Here my ajax request and how to select row values function
var grid = $("#InvoceGrid").data('kendoGrid');
var sel = $("input:checked", grid.tbody).closest("tr");
var items = [];
$.each(sel, function (idx, row) {
var item = grid.dataItem(row);
items.push(item);
});
var grid1 = $("#DeliveryGrid").data('kendoGrid');
var sel1 = $("input:checked", grid1.tbody).closest("tr");
var items1 = [];
$.each(sel1, function (idx, row) {
var item1 = grid1.dataItem(row);
items1.push(item1);
});
$.ajax({
url: '../HeadOffice/CreateInvoice',
type: 'POST',
data: JSON.stringify({ 'items': items, 'items1': items1, 'refnum': refnum }),
contentType: 'application/json',
traditional: true,
success: function (msg) {
if (msg == "0") {
$("#lblMessageInvoice").text("Invoices have been created.")
var del = $("#InvoiceOKWindow").data("kendoWindow");
del.center().open();
var del1 = $("#InvoiceDetail").data("kendoWindow");
del1.center().close();
$("#grdDlvInv").data('kendoGrid').dataSource.read();
}
else {
$("#lblMessageInvoice").text("Problem occured. Please try again later.")
var del = $("#InvoiceOKWindow").data("kendoWindow");
del.center().open();
return false;
}
}
});
This is my C# part
[HttpPost]
public string CreateInvoice(List<Pm_I_GecisTo_Result> items, List<Pm_I_GecisFrom_Result> items1, string refnum)
{
try
{
if (items != null && items1 != null)
{
//do Something
}
else
{
Log.append("Items not selected", 50);
return "-1";
}
}
catch (Exception ex)
{
Log.append("Exception in Create Invoice action of HeadOfficeController " + ex.ToString(), 50);
return "-1";
}
}
But when i send just one row it works but when i try to send more than one value it post null and create problem
How can i solve this? Do you have any idea?
EDIT
I forgot to say but this way is working on localy but when i update server is not working proper.

$.ajax({
url: '../HeadOffice/CreateInvoice',
type: 'POST',
async: false,
data: { items: items, items1: items1 }
success: function (msg) {
//add codes
},
error: function () {
location.reload();
}
});
try to call controller by this method :)

Retrieving data from myapifilms.com api

I am following a tutorial on YouTube showing how to get data from the myapifilms.com api and I am having trouble rendering the data to HTML. Currently my ajax call is working and the data is showing in the console. The problem I am having is getting the data to show on the page itself. I searched through the question already asked but had no luck. Here's my js code so far:
$(document).ready(function(){
$("#searchMovie").click(searchMovie);
var movieTitle = $("#movieTitle");
var table = $("#results");
var tbody = $("#results tbody"); //table.find("tbody");
function searchMovie() {
var title = movieTitle.val();
$.ajax({
url: "http://www.myapifilms.com/imdb/idIMDB?title="+ title +"&token= + token goes here +&format=json&language=en-us&aka=0&business=0&seasons=0&seasonYear=0&technical=0&filter=2&exactFilter=0&limit=1&forceYear=0&trailers=0&movieTrivia=0&awards=0&moviePhotos=0&movieVideos=0&actors=0&biography=0&uniqueName=0&filmography=0&bornAndDead=0&starSign=0&actorActress=0&actorTrivia=0&similarMovies=0&adultSearch=0&goofs=0&quotes=0&fullSize=0&companyCredits=0",
dataType: "jsonp",
success: renderMovies
})
function renderMovies(movies) {
console.log(movies);
tbody.empty();
for(var m in movies) {
var movie = movies[m];
var title = movie.title;
var plot = movie.simplePlot;
var posterUrl = movie.urlPoster;
var imdbUrl = movie.urlIMDB;
var tr = $("<tr>");
var titleTd = $("<td>").append(title);
var plotTd = $("<td>").append(plot);
tr.append(titleTd);
tr.append(plotTd);
tbody.append(tr);
}
}
}
});
I feel like I am so close but can't quite figure what I am missing. Again I was following a tutorial so if there's a better way to accomplish this goal I'm definitely open to suggestions.
Update:
I changed my code to this and I'm getting undefined in the browser. I changed the for loop to this
success: function (movies) {
console.log(movies);
tbody.empty();
for (var m in movies) {
$(".movies").append("<h3>"+ movies[m].title +"</h3>");
$(".movies").append("<h3>"+ movies[m].plot +"</h3>");
}
}

I figured out a solution, instead of using myapifilms, I used the tmdb api instead. Changing my code to this worked:
var url = 'http://api.themoviedb.org/3/',
mode = 'search/movie?query=',
input,
movieName,
key = 'myapikey';
//Function to make get request when button is clicked to search
$('button').click(function() {
var input = $('#movie').val(),
movieName = encodeURI(input);
$.ajax({
type: 'GET',
url: url + mode + input + key,
async: false,
jsonpCallback: 'testing',
contentType: 'application/json',
dataType: 'jsonp',
success: function(json) {
console.dir(json.results);
for (var i = 0; i < json.results.length; i++){
var result = json.results[i];
$(".moviesContainer").append('<div class="movies col-md-12">'+
'<img class="poster" src="http://image.tmdb.org/t/p/w500'+ result.poster_path +'" />'
+'<h3>'+ result.title +'</h3>'
+'<p><b>Overview: </b>'+ result.overview +'</p>'
+'<p><b>Release Date: </b>'+ result.release_date +'</p>'
+'</div>');
}
},
error: function(e) {
console.log(e.message);
}
});
});

populate dropdown via ajax and automatically select a value

I'm kinda new to javascript and ajax.
The page that I'm building will ask user to select from a list. Upon selection, a dropdown will be populated from database, and a default value of that dropdown will be automatically selected.
So far I've been able to populate the dropdown OR automatically select a value. But I can't do them both in succession.
Here's the Javascript snippet that gets called upon selection of an item from a a list:
function onSelectProduct(data, index) {
//part 1: auto populate dropdown
$.ajax({
type: "POST",
async: true,
url: "http://localhost:8007/Webservice.asmx/GetUnitsByProductID",
data: "{productID: " + data.ID + "}",
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (result) {
$("#Details_" + index + "_ConversionID").empty();
$.each(result.d, function (key, val) {
var option = document.createElement('option');
option.text = val.Name;
option.value = val.ID;
$("#Details_" + index + "_ConversionID").append(option);
});
}
});
//part 2: select one of the values
var ddl = document.getElementById("Details_" + index + "_ConversionID");
var opts = ddl.options.length;
for (var i = 0; i < opts; i++) {
if (ddl.options[i].value == data.StockUnitID){
ddl.options[i].selected = true;
break;
}
}
}
I used
$("#Details_" + index + "_ConversionID").empty(); because I started with all possible options in the dropdown.
If I started with an empty dropdown, ddl.options.length will return 0 for some reason.
From my understanding, the ajax script that I wrote doesn't really change the properties of the dropdown box (ddl.options.length returns either 0 or the full list with or without the ajax operation). If that's true, then what's the right way to populate that dropdown?
Btw I'm using cshtml and .net.
Thanks!

Well you can try using $.when and .done as below:
It will execute your code once the options have been set
$.ajax({
type: "POST",
async: true,
url: "http://localhost:8007/Webservice.asmx/GetUnitsByProductID",
data: "{productID: " + data.ID + "}",
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (result) {
$("#Details_" + index + "_ConversionID").empty();
$.when(
$.each(result.d, function (key, val) {
var option = document.createElement('option');
option.text = val.Name;
option.value = val.ID;
$("#Details_" + index + "_ConversionID").append(option);
})).done(function(){
//part 2: select one of the values
var ddl = document.getElementById("Details_" + index +"_ConversionID");
var opts = ddl.options.length;
for (var i = 0; i < opts; i++) {
if (ddl.options[i].value == data.StockUnitID){
ddl.options[i].selected = true;
break;
}
}
});
}
});
I would also like to suggest one thing! Please do not use complete url as your ajax url since when you host the site this will change and http://localhost:8007/ will no longer be available!

You can write following code in Ajax Success :
$("#Details_"+index +"_ConversionID").val('value you want to select');
Thanks

jQuery UI AutoComplete: Only allow selected valued from suggested list

I am implementing jQuery UI Autocomplete and am wondering if there is any way to only allow a selection from the suggested results that are returned as opposed to allowing any value to be input into the text box.
I am using this for a tagging system much like the one used on this site, so I only want to allow users to select tags from a pre-populated list returned to the autocomplete plugin.

You could also use this:
change: function(event,ui){
$(this).val((ui.item ? ui.item.id : ""));
}
The only drawback I've seen to this is that even if the user enters the full value of an acceptable item, when they move focus from the textfield it will delete the value and they'll have to do it again. The only way they'd be able to enter a value is by selecting it from the list.
Don't know if that matters to you or not.

I got the same problem with selected not being defined. Got a work-around for it and added the toLowerCase function, just to be safe.
$('#' + specificInput).autocomplete({
create: function () {
$(this).data('ui-autocomplete')._renderItem = function (ul, item) {
$(ul).addClass('for_' + specificInput); //usefull for multiple autocomplete fields
return $('<li data-id = "' + item.id + '">' + item.value + '</li>').appendTo(ul);
};
},
change:
function( event, ui ){
var selfInput = $(this); //stores the input field
if ( !ui.item ) {
var writtenItem = new RegExp("^" + $.ui.autocomplete.escapeRegex($(this).val().toLowerCase()) + "$", "i"), valid = false;
$('ul.for_' + specificInput).children("li").each(function() {
if($(this).text().toLowerCase().match(writtenItem)) {
this.selected = valid = true;
selfInput.val($(this).text()); // shows the item's name from the autocomplete
selfInput.next('span').text('(Existing)');
selfInput.data('id', $(this).data('id'));
return false;
}
});
if (!valid) {
selfInput.next('span').text('(New)');
selfInput.data('id', -1);
}
}
}

http://jsfiddle.net/pxfunc/j3AN7/
var validOptions = ["Bold", "Normal", "Default", "100", "200"]
previousValue = "";
$('#ac').autocomplete({
autoFocus: true,
source: validOptions
}).keyup(function() {
var isValid = false;
for (i in validOptions) {
if (validOptions[i].toLowerCase().match(this.value.toLowerCase())) {
isValid = true;
}
}
if (!isValid) {
this.value = previousValue
} else {
previousValue = this.value;
}
});

This is how I did it with a list of settlements:
$("#settlement").autocomplete({
source:settlements,
change: function( event, ui ) {
val = $(this).val();
exists = $.inArray(val,settlements);
if (exists<0) {
$(this).val("");
return false;
}
}
});

i just modify to code in my case & it's working
selectFirst: true,
change: function (event, ui) {
if (ui.item == null){
//here is null if entered value is not match in suggestion list
$(this).val((ui.item ? ui.item.id : ""));
}
}
you can try

Ajax submission and handling
This will be of use to some of you out there:
$('#INPUT_ID').autocomplete({
source: function (request, response) {
$.ajax({
type: 'POST',
contentType: 'application/json; charset=utf-8',
url: autocompleteURL,
data: "{'data':'" + $('INPUT_ID').val() + "'}",
dataType: 'json',
success: function (data) {
response(data.d);
},
error: function (data) {
console.log('No match.')
}
});
},
change: function (event, ui) {
var opt = $(this).val();
$.ajax({
type: 'POST',
contentType: 'application/json; charset=utf-8',
url: autocompleteURL,
data: "{'empName':'" + name + "'}",
dataType: 'json',
success: function (data) {
if (data.d.length == 0) {
$('#INPUT_ID').val('');
alert('Option must be selected from the list.');
} else if (data.d[0] != opt) {
$('#INPUT_ID').val('');
alert('Option must be selected from the list.');
}
},
error: function (data) {
$(this).val('');
console.log('Error retrieving options.');
}
});
}
});

I'm on drupal 7.38 and
to only allow input from select-box in autocomplete
you only need to delete the user-input at the point,
where js does not need it any more - which is the case,
as soon as the search-results arrive in the suggestion-popup
right there you can savely set:
**this.input.value = ''**
see below in the extract from autocomplete.js ...
So I copied the whole Drupal.jsAC.prototype.found object
into my custom module and added it to the desired form
with
$form['#attached']['js'][] = array(
'type' => 'file',
'data' => 'sites/all/modules/<modulname>_autocomplete.js',
);
And here's the extract from drupal's original misc/autocomplete.js
modified by that single line...
Drupal.jsAC.prototype.found = function (matches) {
// If no value in the textfield, do not show the popup.
if (!this.input.value.length) {
return false;
}
// === just added one single line below ===
this.input.value = '';
// Prepare matches.
=cut. . . . . .

If you would like to restrict the user to picking a recommendation from the autocomplete list, try defining the close function like this. The close function is called when the results drop down closes, if the user selected from the list, then event.currentTarget is defined, if not, then the results drop down closed without the user selecting an option. If they do not select an option, then I reset the input to blank.
//
// Extend Autocomplete
//
$.widget( "ui.autocomplete", $.ui.autocomplete, {
options: {
close: function( event, ui ) {
if (typeof event.currentTarget == 'undefined') {
$(this).val("");
}
}
}
});

You can actually use the response event in combination to the change event to store the suggested items like so:
response: function (event, ui) {
var list = ui.content.map(o => o.value.toLowerCase());
},
change: function (event, ui) {
if (!ui.item && list.indexOf($(this).val().toLowerCase()) === -1 ) { $(this).val('');
}
