She's not really...See valorForro, is restricted to the scope of the method RemoverForro(valor), as well as land max_fields7 the $(add_button7).click(), although in that case they were not declared. .function RemoverForro(valor){ var valorForro = valor; } And you are trying to access it from:$(wrapper7).on("click","#delete", function(e){ e.preventDefault(); document.getElementById("tipo_forro_div_"+ valorForro).remove(); l--; <?= $l--?> }) To "fix" you can declare and boot out of the method and only change its value according to the conditions.var valorForro = null; function RemoverForro(valor){ valorForro = valor; } $(add_button7).click(function(e){ e.preventDefault(); if(l < max_fields7){ l++; $(wrapper7).append( '<div id="tipo_forro_div_'+ l +'" class="input-group margin">'+ '<div id="tipo_forro_nome_'+ l +'"></div>'+ '<div class="input-group-btn">'+ '<button type="button" class="btn btn-danger" id="delete" onclick="RemoverForro('+ l +')" href="#">Remover</button>'+ '</div>'+ '&emsp;<select name="forro_tipo'+ l +'" id="forro_tipo'+ l +'" required style="width: 25%; margin-bottom: 10px; margin-top: 20px" onchange ="exibir_ocultar_forro(this, '+ l +')">'+ '<option value="">Selecione</option>'+ '<option value="1">Gesso (Placas)</option>'+ '<option value="2">Gesso Acartonado</option>'+ '<option value="3">Fibra Mineral</option>'+ '<option value="4">Laje</option>'+ '<option value="0">Outros</option>'+ '</select>'+ '<div id="outros_forro'+ l +'" style="display: none; margin-bottom: 10px; margin-left: 15px; font-size: 14px"><input id="outros_forro'+ l +'" type="text" placeholder="Especifique" name= "outros_forro'+ l +'"/></div>'+ '<input type="text" style= "width: 21%; margin-left: 15px; font-size: 14px" name="forro_qtd'+ l +'" id= "forro_qtd'+ l +'" placeholder="Quantidade" required/> m²'+ '</div>'); //add input box } $(wrapper7).on("click","#delete", function(e){ e.preventDefault(); document.getElementById("tipo_forro_div_"+ valorForro).remove(); l--; <?= $l--?> });

I managed to solve it as follows:click(){ mainWindow.loadFile('index.html') }

When you use the:$('.botao').on('click'); You are linking the click event to each element that contains the existing ".botao" class in the document. The main problem of this method is that if you need to add an element dynamically with the same class ".botao", he will not own the click event, since it was added to the document later.And as for:$(document).on('click', '.botao'); In this case, the click event is linked to the document itself, not to the specific elements of the ".botao" class. This is the most recommended method of using, as when adding new elements to the document they will still have the reference of the click event linked to the document.

The problem is that in this button:<button type="button" class="close" data-dismiss="modal" aria-label="Close" onclick="javascript:window.location.reload()"><span aria-hidden="true">×</span></button> the code:onclick="javascript:window.location.reload()"causes the page to be reloaded, you can take this onclick event or put it back void.<button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">×</span></button> onclick="javascript:void(0)"

Just escape the character, this is done using the inverted bar "\". So it would be as followsdocument.getElementById('table').innerHTML += '<tr id="'+obj[i].id+file+'"><td>'+obj[i].id+'</td><td>'+obj[i].name+'</td><td align="center" valign="top"><img src="'+obj[i].picture+'"/></td><td><button onclick="remove(\''+obj[i].id+file+'\')">Excluir</button><br/><button onclick="Alterar('+obj[i].id+')">Alterar</button></td></tr>'; Or as in your example<td onclick="remove(\''+***+'\')"> For example, adding something to the tabledocument.getElementById('table').innerHTML = '<td onclick="remove(\''+***+'\')">';

You're document.querySelector("#infoRight").setAttribute('style', 'display: block;') Display block makes it break the line. You switch to inline display document.querySelector("#infoRight").setAttribute('style', 'display : inline;')

You can pass the value through Querystring, so just change where you have google.com and add the value to pass. For example$ta = "<td href=\"\" onClick=\"window.open('http://google.com?taRaiz={$RESP[taRaiz]}','Janela','toolbar=no,location=no,directories=no,status=no,menubar=no,scrollbars=no,resizable=no,width=600,height=300,left=25,top=25'); return false;\">$RESP[taRaiz]</td>"; And on the other page, to get it, you can use it <?php $taRaiz = $_GET['taRaiz']; // fazer o que precisas com esse valor

You did not initialize the Adapter object, are creating an installment of the adapter directly in the setAdapter method.To solve you can replace lvPosts.setAdapter(new AdapterListView(MainActivity.this, list, mImageLoader)); by Adaptador = new AdapterListView(MainActivity.this, list, mImageLoader); lvPosts.setAdapter(Adaptador);

I ended up solving the problem using the attribute disability , defining in the function check() disable to "", and in the function clean() to falsefunction limpar(){ nind = 0; tentativas = 5; ncertas = 0; document.getElementById("mstr").style.display = ""; document.getElementById("dca").style.display = 'none'; for(var i = 0; i < 27; i++) { tc[i].style.color = '#ffff03'; tc[i].disabled = false; } for(var i = 0; i < paltd.length; i++) { paltd[i].innerHTML = "-"; paltd[i].style.display = 'none'; } document.getElementById("ptnt").innerHTML = tentativas; } function verificar(b,num){ //alert(b); //alert(num); var nerr = 0; for (i = 0; i < palavrasecreta.length; i++) { if(b == palavrasecreta[i]) { paltd[i].innerHTML = b; ncertas += 1; tc[num-1].style.color = '#60ff90'; }else{ nerr +=1; } } if (nerr == palavrasecreta.length) { tentativas -= 1; document.getElementById("ptnt").innerHTML = tentativas; tc[num-1].style.color = '#773333'; } //alert(ncertas); tc[num-1].setAttribute("disabled", ""); verificarjogo(ncertas); }

I managed to find the solution to my problem and would like to share, if anyone else has the same scenario I had, the solution was very obvious, that is, the layout that contains the component in which I want to implement the action is being inflated inside the adapter, so that's where I need to put it, inside the getView even, I do the implentation of the click event and the code itself already brings me the change in the clicked position of the list: my problem was solved with only this code in the HinosAdapter class getView:imLike.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { Toast.makeText(context, "clicado na posição: "+position, Toast.LENGTH_SHORT).show(); imLike.setImageResource(R.drawable.ic_favorite); } });

Using the method https://developer.mozilla.org/pt-BR/docs/Web/API/WindowBase64/atob to decode the base64, you can convert the result to JSON object and take the data nome and idade.Getting the parameters in the function, you can mount a URL and open in a new window with window.open:function funcao1(dom,seg,par){ var par = atob(par).replace(/'/g,"\""); // substituo aspas simples por aspas duplas para o JSON par = JSON.parse(par); // crio o JSON par = "nome="+par.nome+"&idade="+par.idade; // monto a variável par com o nome e idade var url_ = "http://www."+dom.toLowerCase()+".com/pesquisa.php?"+par+"&segmento="+seg; window.open(url_,"_blank","..."); // abre em nova janela } As the snippet here does not open popup, the variable result url_ in the function above will be:http://www.teste.com/pesquisa.php?nome=joao&idade=29&segmento=ABCD Note: where it has "..." No window.open, you can set the properties of the window ( https://www.w3schools.com/jsref/met_win_open.asp ).

I will leave an example of how to avoid an object from one screen to another just implement by changing the get set and class.Screen 1:btnOK.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { /* Instanciando objeto que será enviado para a Tela 2 */ Usuario u = new Usuario(); /* Recebendo os valores no objeto para enviar para a próxima tela através do método putExtra() */ u.setLogin("usuario tal"); u.setSenha("123"); Intent it = new Intent(MainActivity.this, Tela2.class); //Passando os valores it.putExtra("usuario", u); startActivity(it); //Opcional: encerrar a activity //finish(); } }); Screen 2://Recebendo os valores passados como String Usuario u = (Usuario) getIntent().getSerializableExtra("usuario"); String login = u.getLogin(); String senha = u.getSenha(); Class:public class Usuario implements Serializable { //... } Source: https://github.com/thiago-cury/aulas-android/tree/master/ExIntentSegundaTelaEnviandoObjetoAPI19

Maybe you need to learn what it is https://pt.wikipedia.org/wiki/Programa%C3%A7%C3%A3o_orientada_a_eventos . Javascript is an event-oriented language (at least superficially) and this paradigm controls the flow through external indications, called https://pt.wikipedia.org/wiki/Evento_(computa%C3%A7%C3%A3o) .This means that by creating a function and assigning its execution to an event the entire section of the function code will run from this event. Basically your code is waiting for a user action to change the value of the variables, this means that the remainder of your code has already been run independently of what is before it, that is, you are checking the value of the variable before it is changed.var valor = false; function clique() { valor = true; // o valor agora é 'true', pois a função foi executada só agora console.log(valor); } // essa linha vai ser executada independente do que há antes dela. O valor ainda é 'false', pois o usuário ainda não clicou no link console.log(valor);<a href="#" onclick="clique()">Clique em mim!</a>Generally https://pt.wikipedia.org/wiki/Funcionalidade are https://pt.wikipedia.org/wiki/Algoritmo that are executed when there is a call. When writing your function you will not be running. To make the call in javascript you must start with the function name and finish by inserting the parameters between relatives nomeFuncao('parametro1'), if you have no parameter, the relatives are empty nomeFuncao().When you "link" a function to an HTML DOM event, for example onclick='nomeFuncao()', you are "saying to javascript" that when the user clicks on this DOM will run the function codes nomeFuncao without parameters.

One way to "create" a clickable div would be:#clicavel{ cursor: pointer; } #clicavel:hover{ color: red; } #clicavel:active{ color: blue; }<script> function executaAcao(){ alert("Eu vou para o Google"); window.location = "http://google.com"; } </script> <div id="clicavel" onclick="executaAcao()">CLIQUE AQUI</div>We use the method onclick to assign a javascript function to the html element and attributes :hover and :active to customize element style according to mouse actions.

You can change SVG properties with JavaScript by changing attributes with setAttribute:function alterarSvg(){ var svg_line = document.querySelector("#meusvg line"); // seleciono o line do SVG svg_line.setAttribute("x2","10"); // muda posição x2 svg_line.setAttribute("stroke","blue"); // muda a cor para azul }<svg id="meusvg" width="100" height="100"> <line x1="10" y1="10" x2="100" y2="100" stroke="green" stroke-width="4" /> </svg> <br /> <button type="button" onclick="alterarSvg()">Clique-me</button>

Set a variable within the constructor method, for example:this.interval = null; She'll keep the timer https://developer.mozilla.org/en-US/docs/Web/API/WindowOrWorkerGlobalScope/setInterval , now create a method to clean the timer:clear() { clearInterval(this.interval); this.interval = null; } In the constructor method make the bind of the new method:this.clear = this.clear.bind(this); You must make the following modifications to the methods inc and dec:inc() { if (this.interval === null) { this.interval = setInterval(this.inc, 100); } this.setState({ count: this.state.count + 1 }); } dec() { if (this.interval === null) { this.interval = setInterval(this.dec, 100); } if (this.state.count > 0) { this.setState({ count: this.state.count - 1 }); } } Change events onClick For onMouseDown and add the event onMouseUp which will execute the method clear, thus getting the code:<button onMouseUp={this.clear} onMouseDown={this.inc}>Incrementar</button> <button onMouseUp={this.clear} onMouseDown={this.dec}>Decrementar</button> Example workingclass Counter extends React.Component { constructor(props) { super(props); this.state = { count: parseInt(this.props.value) }; this.interval = null; this.clear = this.clear.bind(this); this.inc = this.inc.bind(this); this.dec = this.dec.bind(this); } inc() { if (this.interval === null) { this.interval = setInterval(this.inc, 100); } this.setState({ count: this.state.count + 1 }); } dec() { if (this.interval === null) { this.interval = setInterval(this.dec, 100); } if (this.state.count > 0) { this.setState({ count: this.state.count - 1 }); } } clear() { clearInterval(this.interval); this.interval = null; } render() { return ( <div> <p> O valor inicial é: <code>{this.props.value}</code>. </p> <div> O valor <strong>atual</strong> é: <code>{this.state.count}</code>. </div> <div> <button className="inc" onMouseUp={this.clear} onMouseDown={this.inc}>Incrementar</button> <button className="dec" onMouseUp={this.clear} onMouseDown={this.dec}>Decrementar</button> </div> </div> ); } } ReactDOM.render(<Counter value="0" />, document.getElementById('app'));button { border: 0; color: #fff; cursor: pointer; font-family: 'Verdana', sans-serif; font-size: 1em; padding: 8px; text-transform: uppercase; } .inc { background: #388E3C; margin-right: 14px; } .dec { background: #E57373; }<script src="https://cdnjs.cloudflare.com/ajax/libs/react/15.1.0/react.min.js"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/react/15.1.0/react-dom.min.js"></script> <div id="app"></div>If you prefer you can see working on https://codesandbox.io/s/jvonkwn9l5 Reference https://developer.mozilla.org/en-US/docs/Web/API/WindowOrWorkerGlobalScope/setInterval https://developer.mozilla.org/en-US/docs/Web/API/WindowOrWorkerGlobalScope/clearInterval

In your XML you can use the attribute onClick so they all make a call to the click method.XML XML XML<Button android:id="@+id/buttonOne" ... android:onClick="onButtonClick"/> <Button android:id="@+id/buttonTwo" ... android:onClick="onButtonClick"/> Activitypublic void onButtonClick(View view) { switch (view.getId()) { case R.id.buttonOne: { break; } case R.id.buttonTwo: { break; } case R.id.buttonThree: { break; } ... } } This way you can save some code lines. Another thing, depending on which functions your screen buttons have, you can also use one RecyclerView, which will also save you a lot of code. But this will depend on the function exercised by each button if they are very different, I believe that you use the example of the same code, but if you get the same end, you could use a ReylerView.For example, if you want to open a screen for each button, you could use the RV and depending on the clicked button, return one Bundle to open the corresponding screen, and so on.

If you want to use more than one event in a single button I recommend using https://developer.android.com/guide/topics/ui/controls/togglebutton.html , I think there must be a way to add more states to https://developer.android.com/guide/topics/ui/controls/togglebutton.html

In your HTML, you missed giving id "tela" input:<input id="tela" type="text" class="form-control" placeholder=""> In your JavaScript, you had placed a comma instead of closing keys between the object model and the object handlers. Besides, you were doing view.displayTela instead of calling the function doing view.displayTela(). Fixing, stay like this:var model = { tela: [""], addTecla: function(tecla){ this.tela.push(tecla); } } var handlers = { addTecla: function(tecla){ model.addTecla(tecla); view.displayTela(); } } Finally, its function displayTela was stirring innerHTML the input. Better use value in this case:var view = { displayTela: function(){ var pTela = document.getElementById('tela'); pTela.value = ''; var tela = model.tela.join(''); pTela.value = tela; } } He's got a lot of other things that he can do to get better there, but for now, he's already solved the problem. Good studies!
