Is there any way to stop the job?

Burma

When pressed on the button, I have a window on my left of the map, and the possibility of placing the marker on the screen, after the window is closed, the possibility of placing the marker should disappear. I got him on the chequebox so he could only work when he was switched on, and then he turned off, but it didn't work. I'm just starting to work with that language, and I'm happy to have any help. Thank you.

document.querySelector('.checkbox').addEventListener('click',() =>{
  if(document.querySelector('.checkbox').checked){
      var theMarker = {};
  map.on('click', function (e) {
    lat = e.latlng.lat;
    lon = e.latlng.lng;

    console.log("You clicked the map at LAT: " + lat + " and LONG: " + lon);
    //Clear existing marker,

    if (theMarker != undefined) {
      map.removeLayer(theMarker);
    }
    ;

    //Add a marker to show where you clicked.
    theMarker = L.marker([lat, lon]).addTo(map);

  });

}else {

}

});

Complete the function by the operator https://developer.mozilla.org/ru/docs/Web/JavaScript/Reference/Statements/return
Pay attention to: He's not just gonna stop the job, but he's gonna get the meaning back. That means that the challenge to the function will be what you've returned as a result.
Cease the cycle work;

As I commented on @Triby's response, apart from solving the problem of putting the array of students into the builder, this is far from being POO. For several reasons:the current methods that are called in the class builder do nothing but sneeze there, every time the class is instituted, these methods will jump;Plus a class that asks you what she should give you (in the case of total students) has no use. In order to know the number of students in the Hall, the number of items in the pupil array should be counted.The method asignarNombres It is also questionable. In a usual context an array of students would be filled from outside and in the class there might be a method to update some student if needed.There's supposed to be a class. Alumno to be able to use their methods and make the most of the POO.This would be a basic model of your class with some improvements that already point to what the POO proposes./*Clase Alumno*/ class Alumno { constructor(nombre, edad) { this._nombre = nombre; this._edad = edad; this.asistencias = 0; } set nombre(nombre) { this._nombre = nombre; } get nombre() { return this._nombre; } toString() { return ${this._nombre} \t ${this._edad} \t ${this.asistencias}; } } /Clase Salon/ class Salon { constructor(alumnos) { this.alumnos = alumnos; } contarAlumnos() { /Simplemente contamos al erray/ return this.alumnos.length; } listarAlumnos() { /Nótese que aquí usamos el método toString de la clase Alumno/ let s = ""; this.alumnos.forEach(function(obj){ s+=obj.toString()+'\n'; }); return s; } updateAlumno(index, nombre) { this.alumnos[index].nombre = nombre; } addAlumno(alumno) { this.alumnos.push(alumno); } tomarAsistencia() { this.alumnos.forEach(function(obj){ // for (var key in lstAlumnos) { // var mItem = this.alumnos[key]; let s = prompt(¿Está presente ${obj.nombre}?); if (s.toUpperCase() === 'P') { obj.asistencias++; } }); } /No me meto con este método, entendiendo lo otro podrás resolverlo de la mejor manera/ static mostrarAsistencias(alumnos) { for (let alumno in alumnos) { document.write( ${alumnos[alumno][0]}<br> Asistencias: ${alumnos[alumno][1]}<br> Inasistencias: 5 - ${alumnos[alumno][1]}<br> ); if (alumnos[alumno][1] < 6) { document.write('Reprobado por inasistencias<br><br>'); } else { document.write('<br>'); } } } } /Creamos una lista de alumnos/ let lstAlumnos = [new Alumno('Pedro', 20), new Alumno('Marta', 22)]; /Se la pasamos al constructor de Salon/ let mSalon = new Salon(lstAlumnos); console.log(Total de alumnos: ${mSalon.contarAlumnos()}); console.log('Lista de alumnos inicial: '); console.log(mSalon.listarAlumnos()); /Cambiamos el nombre de uno/ mSalon.updateAlumno(0, 'Peter*'); mSalon.tomarAsistencia(); console.log('Lista con asistencia y nombre de Pedro cambiado: '); console.log(mSalon.listarAlumnos()); /Llegó un nuevo alumno/ mSalon.addAlumno(new Alumno('Carla',20)); mSalon.tomarAsistencia(); console.log('Lista actualizada: '); console.log(mSalon.listarAlumnos());

Function setInterval() Returns the ID to the newly established interval for subsequent removal. To remove the function clearInterval()♪Accordingly, a global variable (which is generally poor) and a function is used to remove the interval in this case clearInterval()var intervalId = 0; function start_add() { var data = $("#test").val(); $("#test").val(parseInt(data) + 1); } $("#refresh").click(function() { if(intervalId > 0) { clearInterval(intervalId); $(this).text('Старт'); intervalId = 0; } else { intervalId = setInterval(start_add, 2000); $(this).text('Стоп'); } });#refresh { color: #FFED6D; font: 14px Arial, Helvetica; font-weight: bold; text-align: center; background: #0084EE; padding: 2px 10px; margin: 15px; cursor: pointer; width: 100px; border: 1px solid #777; } #refresh:hover { background: #2F9AEE; }<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script> <div id="refresh">Старт</div> <br> <br> <input type="text" name="test" id="test" value="1">

Always use ; and here is why:JavaScript is a language that makes statements to the browser. The character used to separate these statements is ; and the same must always be used.The code can work without the point and comma after a statement, but for this it is necessary that there is an end-of-line or a correct syntax.Thank you to @Gabriel Gartz for alerting the fact that any logical operator, mathematician or scope delimitation allows to generate the code equally.The biggest problem comes from the fact that we all want to optimise the downloaded files for the browser, as is the case with the files .js and .css which for which we apply compression (remove line breaks, comments, spaces and tabs). In these cases, if there is no proper separation of statements to the browser, they will be interconnected and syntax errors will arise.Let's see with examples: http://jsfiddle.net/zuul/6pxSy/ (click to open JSFIddle)Make an alert without the statement tab ;:alert("olá") Everything goes as expected, we got an alert. http://jsfiddle.net/zuul/6pxSy/1/ (click to open JSFIddle)Perform two alerts without the statement separator, but each alert on your line separated so by the "end-of-line":(r, n or rn depending on the operating system where the file was created)alert("olá") alert("olá novamente") Everything goes as expected, we got two alerts. http://jsfiddle.net/zuul/6pxSy/3/ (click to open JSFIddle)Perform two separate alerts with the statement separator ;:alert("olá"); alert("olá novamente") Everything goes as expected, we got two alerts. http://jsfiddle.net/zuul/6pxSy/6/ (click to open JSFIddle)Perform two alerts without separation declarations ; and with compressed code:alert("olá")alert("olá novamente") Nothing happens and we get a script error on the page:SyntaxError: missing ; before statement alert("olá")alert("olá novamente") http://jsfiddle.net/zuul/6pxSy/7/ (click to open JSFIddle)Based on the attention call made by @Gabriel Gartz, one can verify that if the syntax is correct, the code is executed without errors, even if the statements are separated by something other than the ;:alert('foo')&alert('bar')|alert('zaz') It will generate three alerts as expected.Automatic insert and comma (;)There are some statements that automatically receive an insertion ;:DeclarationExample of the Declarationempty;variablevar a = 1;expressiongreeting = "Hello " + name;do-whiledo qualquerCoisa while (condição);continuecontinue;break breakbreak;returnreturn;♪throw "Error2";They are declarations that must be terminated with the declaration tab ;, reason why they receive automatic insertion of the same if it is not found.What rules for this to happen:The code reading is performed from left to direct. If one is found symbol offensive that is not allowed in any production of grammar, automatic insertion of a point and comma occurs if one of the following conditions is true:O symbol offensive is separated from symbol previous in at least one "end-of-line";O symbol offensive is }.Notes:The automatic insertion of declaration tabs is an extensive topic subject to many rules, but explains why we can get the code to work without using the statement tab when we have a "end-of-line" or a valid syntax.In the case of files already compressed to delete the required characters to the full, it becomes almost impossible to automatically insert the declaration tab because one of the above conditions is no longer present.Documentation: http://bclary.com/2004/11/07/#a-7.9 (English)

Since the fields to, from, subjectand html are always fixed, I would recommend you first to fill in that structure (in the self-executable example, the variable message). Then, depending on that logic (the if you check if there are attachments or not), you would add or not to that base structure the corresponding part of attachments.// Puedes utilizar esta variable para simular si hay o no attachments const hasAttachment = true; // Estructura básica, campos que irán si o si let message = { to: 'to', from: 'Hola ', subject: 'subject', html: 'tplHtml', }; // En función de la condición, si es verdadera, añadimos la parte de los attachments if(hasAttachment) { const attachment = 'contenido del fichero'; message.attachments = [ { content: attachment, filename: "terminosCondicones.pdf", type: "application/pdf", disposition: "attachment" } ]; } console.log('Mensaje: ', message);I hope it serves you. Any doubt, you can use the comments.

I don't think it's complicated. We need to do exactly as you described. We're only interested in the meanings, so we're clearing the keys:var a_values = Object.keys(a).map(function(key){ return a[key]; }); var b_values = Object.keys(b).map(function(key){ return b[key]; }); Then we're looking for a unique set:var res = []; for (var a_key in a_values) { if (b_values.indexOf(a_values[a_key]) == -1) { res.push(a_values[a_key]); } } Working example: https://jsfiddle.net/ejbszs0v/1/

Shortly, there's a number equal to 0. true♪Therefore, the cycle for and while In your examples, it looks virtual:while (true) { // do smth. } When variable i It's 0, it's not going to change. false and the cycle is no longer complete.while(0) { console.log('я не выполнюсь'); } console.log('такие дела ¯\(ツ)/¯');

The solution you seek goes through the correct use of the directive ngForm.It serves exactly for you to isolate the scope of each form and disable the save button of each input individually. For example in the code below:<div ng-repeat="item in habilidades"> <ng-form name="itemForm"> <input type="text" name="nomeItem" ng-model="item.nome" required> <button ng-disabled="[CONDIÇÃO PARA DESABILITAR]"> Salvar </button> <ng-form> </div> Where is condition to disable you can use various expressions such as:!itemForm.$valid itemForm.$invalid Where itemForm is the property name the ng-form, that is, you check all validations of all inputs of the form (in this case in particular is only the required required of one input).Or it is possible to check the validity of a input specific so:!itemForm.nomeItem.$valid itemForm.nomeItem.$invalid Where nomeItem is the property name the input inside the form itemForm.If there are any questions, you can search for form validations in these links: https://docs.angularjs.org/api/ng/directive/ngForm https://docs.angularjs.org/api/ng/type/form.FormController

Sadly cutting the recording with a combination of keys is not that simple. As indicated by https://github.com/Uberi/speech_recognition/blob/master/reference/library-reference.rst :`recognizer_instance.record(source: AudioSource, duration: Union[float, None] = None, offset: Union[float, None] = None) -> AudioData: Records up to duration seconds of audio from source (an AudioSource instance) starting at offset (or at the beginning if not specified) into an AudioData instance, which it returns.If duration is not specified, then it will record until there is no more audio input.Therefore, you have two more hand alternatives.Set a fixed duration of recording.audio = r.record(source, duration=20) Use silence detection.r.adjust_for_ambient_noise(source, duration=1) audio = r.record(source) I know you've tried the second one, but maybe it'll help you check the documentation, since it's important for it to work out that while it's calibrating it is trying to be quiet, and you can also use the parameter. duration to try to have a good calibration.

I don't think so. The ability to write a literate code will come over time if, of course, practice regularly. For a newcomer (especially for only three months of experience) ovnocode and slow speed is a perfectly normal picture. He just has nowhere to know how to write the code literate and fast (and unfortunately not even in institutions). Over time, if a newcomer has a head on his shoulders and a desire to develop, he will build positive and negative experiences, learn to distribute his time and effort in a literate manner, and the process will move from a dead end. The basic conditions are regular practice and self-learning. The painting you described is very familiar to many (reading your lines, remembering that almost the same thing happened to me) - breaks of time, regular beans, love of crutches, pervasive ovinecode, out of control. There's no silver bullet here, it's a growth disease. It is cured over time, subject to the above conditions. In any case, a good help will be help in caring in other people's originals (Githab at your service), reading the appropriate literature. http://www.ozon.ru/context/detail/id/3159814/ McConella or http://www.ozon.ru/context/detail/id/1308678/ Faulera. Also inquire about the refactoring - the study of its principles can help to understand how the code should be written. If you're writing on C# in Visual Studio, then Resharper could be the most excellent assistant for you. He can see a thousand potential problems in your code and just make it easier. Also, the existence of a mentor who could show and explain something might be very beneficial. It's usually harder.
