How do you evaporate? "sdasd, dsada, dasdas, dasdas" in such a way ["sdasd", "dsada", "dasdas", "dasdas"]
In JSON.parse makes a mistake:
JSON.parse: unexpected character at line 1 column 1 of the JSON data... ♪

You don't have a line in JSON format, that's a mistake.
The solution is:
```
var str = "sdasd, dsada, dasdas, dasdas";
var array = str.split(", ");
```

The problem is that you're binding the call to the elimination function at the event show.bs.modal which is the event that is launched when displaying the window. I don't know what your HTML is, but I understand it will be something like what I put you next. In that case you must binde the removal function to the "Ok" button click (class .btn-ok) of the modal window:$(document).ready(function() { $('#confirm-delete').on('show.bs.modal',function(){ $('.btn-ok').click(function(){ console.log("Llamamos a la función de eliminación"); }); }); $('#go').click(function() { $('#confirm-delete').modal('show'); }) });</code></pre><pre class="snippet-code-html lang-html prettyprint-override"><code><script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <script src="https://netdna.bootstrapcdn.com/bootstrap/3.0.0/js/bootstrap.min.js"></script> <link href="https://netdna.bootstrapcdn.com/bootstrap/3.0.0/css/bootstrap.min.css" rel="stylesheet"/> <div class="modal fade" id="confirm-delete" aria-hidden="true"> <div class="modal-dialog"> <div class="modal-content"> <div class="modal-header"> <h4 class="modal-title">Eliminar registro</h4> </div> <div class="modal-body"> <label>¿Estás seguro de eliminar el registro?</label> </div> <div class="modal-footer"> <button type="button" class="btn btn-default btn-ok" data-dismiss="modal">Sí</button> <a class="btn btn-danger" data-dismiss="modal">No </a> </div> </div> </div> </div> <button id="go"> X </button></code></pre></div></div></p>

Your response is a JSONObject since he comes in {} but the fine element is JSONArray Comes in. []:JSONObject jsResponse = new JSONObject(response);// pasas tu response a un JSONObject JSONArray jsonArray = jsResponse.getJSONArray("multas"); // a ese JSONObject le extraes un JSONArray llamado multas Then you run it to extract its values: for (int i = 0; i < jsonArray.length(); i++) { JSONObject elemento = jsonArray.getJSONObject(i); String title = elemento.getString("title") }

To achieve it first you need to make a couple of adjustments to your radio_button:Remove the key value (this is assigned directly in the second argument, so it only leaves the value).Add a class (i.e. class) to be able to identify when you click either radio_button.Remove the key id (this is generated automatically using the name and value of the element).Considering the above, your elements should be seen. radio_button:<div class="form-group col-xs-6"> <%= f.label :Competition_type %> <br> <%= f.radio_button :type_competition, "regression", checked: true, class: "my-radio" %> <%= f.label :type_competition, "Regression"%>   <%= f.radio_button :type_competition, "classification", class: "my-radio" %> <%= f.label :type_competition, "Classification"%> </div> And use the following script to update the options select:<script type="text/javascript"> $(document).ready(function() { $('.my-radio').change(function() { if($(this).val() == "regression") { var options = { 'Mean Absolute Error': 'mean_absolute_error', 'Root Mean Squared Error': 'root_mean_squared_error', 'Weighted Mean Absolute Error': 'weighted_mean_absolute_error' }; } else { var options = { 'Accuracy': 'accuracy', 'Mean Utility': 'mean_utility' }; } $('#selectMetric').empty(); $.each(options, function(key, value) { $('#selectMetric').append('<option value="' + value + '">' + key + '</option>'); }); }); }); </script> The script does the following:Detects when the user clicks either radio_button and perform the function.Valid if radio_button to which he clicked has as value 'regression'or has another value, and assigns the corresponding (in the form of hash) in the variable opciones.Removes the element options select.Itera the variable opciones to add each option to the element select.

I found the problem!According to this insert in the ionic team:https://github.com/ionic-team/ionic/issues/12238 An error in the structure is occurring, the solution was the installation of correction via npm as informed in the insue:npm install ionic-angular@nightly --save That's mine. .remove() works perfectly now.

You had it almost right, except for the moment with the names of JObject. Since the object's name will be unknown, use a dictionary like this:var data = JsonConvert.DeserializeObject<Dictionary<string,Data>>(json); public class Data { [JsonProperty("Id")] public int Id { get; set; } [JsonProperty("Type")] public string Type { get; set; } [JsonProperty("Name")] public string Name { get; set; } }

It makes mistake at first because you are trying to use the JSON without it being completely downloaded.An asynchronous discharge is usually used, and an operation called callback is executed.Another way is to make a timer, to wait for so many seconds and try to stop again, with a try / catch... You can try as many times as you like whileuntil the file is completely downloaded.

I'd do that. Removed it to look like a template.<a href="#">FirstLink</a> <a href="#">SecondLink</a> <a href="#">ThirdLink</a> <style> .red-bg{ background-color: red; } </style> <script> document.querySelectorAll("a").forEach(a => { a.addEventListener("click", func); }); function func(){ let x = document.getElementsByClassName("red-bg")[0]; if (x) { x.classList.remove("red-bg"); } this.classList.add("red-bg"); } </script>There's no need to look for all the elements and clean up each background, there's enough to find one of the references already made, because it's always alone.

Like this:"<tr><td><a href='".$object['link']."'>".$object['title']."</a></td><td>".$object['link']."</td></tr>"; Well, if you're gonna need one of two to get it, "<tr><td onclick='window.location.href=document.getElementById(\"link\").innerHTML'>".$object['title']."</td><td id='link'>".$object['link']."</td></tr>";

I am not that much familiar with intern.js. But I've worked in webdriver.io - with Mocha. In that, achieved the abstract tests by created custom modules for the commonly used functions(for example, populating the input test data email id) and imported the modules in individual tests wherever it required.

I've already solved my problem, I share the code in case anyone happens the same. Dim respuesta = obj.login If respuesta.HasRows Then Session.Timeout = 5 Dim key = Session.SessionID Dim array As New JArray() While respuesta.Read obj.id = respuesta(0) For index As Integer = 0 To respuesta.FieldCount - 1 array.Add(respuesta(index)) Next End While Dim o As New JObject() o("Id") = array(0) o("NombreUsuario") = array(1) o("Clave") = array(2) o("CorreoElectronico") = array(3) o("Token") = key Dim dict As New Dictionary(Of String, JObject) dict.Add("data", o) respuesta.Close() obj.TokenKey = key Dim token = obj.token If token Then Response.AddHeader("Content-Type", "application/json") Response.AddHeader("Access-Control-Allow-Origin", "*") Dim stringb As New StringBuilder stringb.Append("{") stringb.Append(Chr(34) & "statusCode" & Chr(34) & ": 200,") stringb.Append(Chr(34) & "statusText" & Chr(34) & ":" & Chr(34) & "OK" & Chr(34) & ",") For Each a In dict stringb.Append(Chr(34) & a.Key.ToString & Chr(34)) stringb.Append(":") stringb.Append(a.Value.ToString) stringb.Append("}") Next Response.Write(stringb) Else print_json("401", "Error de autenticacion", Nothing) End If

The following approach should be taken to import local files:import React from 'react'; import ReactDOM from 'react-dom'; import './index.css'; import * as serviceWorker from './serviceWorker'; import audioSRC from "./media/linkin_park-faint.mp3"; class TimerWrapper extends React.Component { constructor(props) { super(props); this.startTimer = this.startTimer.bind(this); this.state = { timeLeft: null, // Указывает на оставшееся время. Изначально равен null timer: null // Отсылается на наш таймер. Изначально равен null }; } startTimer(timeLeft) { // Вызывается при нажатии на button clearInterval(this.state.timer); // Избавляемся от запусков нескольких таймеров одновременно при нажатии на разные кнопки let timer = setInterval(() => { let timeLeft = this.state.timeLeft - 1; // Отнимает 1 секунду от оставшегося времени if (timeLeft === 0) { // Если оставшееся время равно 0, clearInterval(timer); // очищаем таймер, чтоб таймер не уходил в минус } this.setState({ timeLeft: timeLeft // timeLeft из строки 10 равен timeLeft из строки 17 }); }, 1000); return this.setState({timeLeft: timeLeft, timer: timer}); } render() { return( <div> <h2>Timer</h2> <div> <Button time = '5' startTimer = {this.startTimer}/> <Button time = '10' startTimer = {this.startTimer}/> <Button time = '15' startTimer = {this.startTimer}/> </div> <TimerDisplay timeLeft = {this.state.timeLeft}/> <audio id="end" preload="auto" src={audioSRC}></audio> </div> ) } } class Button extends React.Component { handleStartTimer() { return this.props.startTimer(this.props.time) } render() { return <button onClick = {this.handleStartTimer.bind(this)}> {this.props.time} секунд</button> } } class TimerDisplay extends React.Component { render() { if (this.props.timeLeft === 0) { document.getElementById("end").play() } if (this.props.timeLeft === 0 || this.props.timeLeft === null) { return <div></div> } return <h1>Осталось {this.props.timeLeft} секунд</h1> } } ReactDOM.render(<TimerWrapper />, document.getElementById('root')); serviceWorker.unregister();

HttpClient, DefaultHttpClient, httpGet and ClientProtocolException are classes of https://httpd.apache.org/ , you have to change your implementation using https://developer.android.com/reference/java/net/HttpURLConnection.html if you need to use the Apache classes temporarily, you have to add within your file build.gradle:android { ... ... useLibrary 'org.apache.http.legacy' ... } the recommended is to change https://developer.android.com/reference/java/net/HttpURLConnection.html As for this line you have a problem: String strData = jsonObject.getString(""); is incorrect to have a empty string, you have to define which value to get from the json.or removes that line and defines the name of the array:// String strData = jsonObject.getString(""); JSONArray jsonContent = new JSONArray("nombre del array");

A solution is to convert json in one http://php.net/manual/es/function.json-decode.php .For example:$json = new stdClass(); $json->type = "registrarUsuario"; $json->action = "insert"; $json->status = FALSE; // Indicando true como segundo parámetro obtenemos una matriz asociativa. $datos = json_decode($this->input->post('registrarEmpresa'), true); // Sectores $secores = $datos['registrarEmpresa'][1]; $temp = array(); foreach ($secores as $info) { $temp[] = $info['sector_emp']; } $json->sectors = implode(', ', $temp); // Productos $productos = $datos['registrarEmpresa'][2]; $temp = array(); foreach ($productos as $info) { $temp[] = $info['producto']; } $json->products = implode(', ', $temp); // Certificaciones $certificaciones = $datos['registrarEmpresa'][3]; $temp = array(); foreach ($certificaciones as $info) { $temp[] = $info['certificacion']; } $json->certifications = implode(', ', $temp); header('Content-type: application/json; charset=utf-8'); echo json_encode($json);

I sort of figured it out, so I had to check the key on null, and if storage null was now, I'd have to record the meaning of the function. Thank you all for tips and thoughts, if there's any code tips, I'll be happy to read them."use strict" const date = new Date(), myDay = date.getDay(); let rand, clientLocalHour = date.getHours(), timeFrom = 9, timeTo = 22, firstId = document.getElementById('workoutsАorToday'), secondId = document.getElementById('trialWorkouts'); function workouts(min, max) { rand = Math.floor(Math.random() * (max - min) + min); return rand; } if ('countWorkdayTrening' || 'countWorkdayTrialTrening' || 'countWeekendTrening' || 'countWeekendTrialTrening') === null) { localStorage.setItem('countWorkdayTrening', workouts(10, 20)); localStorage.setItem('countWorkdayTrialTrening', workouts(5, 10)); localStorage.setItem('countWeekendTrening', workouts(1, 9)); localStorage.setItem('countWeekendTrialTrening', workouts(1, 3)); } function recalculationOfData() { if (clientLocalHour >= timeFrom && clientLocalHour <= timeTo) { if (myDay === 1 || myDay === 2 || myDay === 3 || myDay === 4 || myDay === 5) { firstId.innerHTML = localStorage.getItem('countWorkdayTrening'); secondId.innerHTML = localStorage.getItem('countWorkdayTrialTrening'); } else if (myDay === 0 || myDay === 6){ firstId.innerHTML = localStorage.getItem('countWeekendTrening'); secondId.innerHTML = localStorage.getItem('countWeekendTrialTrening'); } } else { firstId.innerHTML.innerHTML = 0; secondId.innerHTML = 0; } }; recalculationOfData();
