html – Mudar src da imagem com javascript

Estou tentando fazer com que a imagem mude cada vez que eu clique no botão, de modo que quando eu clico na image1 ele vire image2 e quando clique nao image2 ela volte a ser image1

<script>
function changeImage(){
  var image = document.getElementById("image");
  if(image.src = "image1.png"){
      image.src = "image2.png";
  }
  else if(image.src = "image2.png"){
      image.src = "image1.png";
  }
}

<img id="image" src="image1.png" width="490" height="364">

<button onclick="changeImage()">Mudar image</button>

só que ele só consegue virar image2, depois disso não volta a ser image1

javascript – How to add div id/class names dynamically to jquery

I am having the below code to capture the div id. I want to capture the first child div of this div. How can i do that in jquery? Pretty new to this so please be a bit kind 🙂

$('.elementor-tab-title').click(function(e) {

var id1= $(this).next("div").attr('id');
var id2=$("#"+id:first-child").attr('id'); // I know this is wrong but i am trying to capture the first child of div starting with id stored in variable id1.
  
alert("Hi "+id1);
alert("Hello "+id2); }

javascript – How can I make the quickview open in mobile?

Javascript – Como adicionar coisas no html e salvar informações do html

Se o título do tópico ficou confuso peço desculpas, porque não sei como eu faria a minha pergunta de forma resumida e correta, mas é o seguinte…

Estou na reta final de um curso de informatica (acaba dia 13 desse mês) e a última tarefa do curso é criar um app para celular usando html, css e javascript e por fim fazer o porte para celular usando o Phonegap

O problema é que o curso não ensina JS (ensina apenas html e css) e eu estou com muita dificuldade em aprender JS, além da data de entrega estar muito próxima, a ideia do meu app é criar listas

inserir a descrição da imagem aqui

Conforme esta na imagem, preciso fazer uma função para que quando eu clique no botão “Adicionar Item” na página seja adicionado outra caixa (um retangulo com input e textarea dentro dele) igual as duas que estão abaixo do input para adicionar titulo a lista

Sou muito leigo com JS, assisti várias vídeo aulas para tentar aprender, mas ainda não consegui entender nem a sintaxe básica direito

O que eu gostaria de saber é: o que eu deveria focar em aprender especificamente de JS, para fazer o botão “Adicionar Item” funcionar da forma que eu descrevi, e como eu faria para que as caixas criadas e as informações digitadas pelo cliente nos inputs e textarea salvem

Desde já peço desculpas pela minha leguisse no assunto

Meu HTML (somente o da pagina da imagem)

css – Quiero hacer una animacion en javascript, pero todo se ejecuta al mismo tiempo

he estado intentando animar unos elementos con javascript y quiero que las animaciones pasen una por una, pero todo se ejecuta al mismo tiempo.

cards.forEach(function(item, index){ //Mover las cartas
    item.classList.add("loaded");
    item.style.transitionDuration = "1300ms"; 
    item.style.transform = "translate("+move+", 50%)";
});

el cambio de clases css es este:

.fade-in{
   opacity:0;
   -webkit-transition: opacity 2s ease-in;
   -moz-transition: opacity 2s ease-in;
   -o-transition: opacity 2s ease-in;
   -ms-transition: opacity 2s ease-in;
   transition: opacity 2s ease-in;
}

.loaded{
    opacity:1;
}

Pero como se ejecuta todo al mismo tiempo, cuando hace el fade in ya hizo la transicion de item.style.transform = "translate("+move+", 50%)"; y entonces no se ve como se mueve.

How to prevent XSS attack on selected window.location in javascript

This is my code where i have a userId in a method SwitchUser_Click. I need to prevent or somehow encode the return value from the switchUser_Click as it includes the UserId of a user vulnerable to XSS attack or redirects.

function SwitchUser_Click(containerElement, OnSuccess) {
            var selecteduserId = $("select", containerElement).val();
            var makeDefault = $(":checkbox", containerElement).is(":checked");
            window.location = "Default.aspx?uId=" + selecteduserId + "&userActive=" + (makeDefault ? "1" : "0");
            OnSuccess();
        }

The belows code is called from aspx page by using Client.RegisterScript and passing the parameters. This is the only place SwitchUser_Click method is used.

function OpenSwitchUser(UserId,modCode,defUrl) {
            defaultUrl = defUrl;
            var options =
            {
                controlUrl: "~/Controls/SwitchUserDialog.ascx",
                params: { uid:UserId, mod: modCode},
                top: 70,
                width: 600,
                height: 2500,
                OKCallback: SwitchUser_Click,
                InitCallback: SwitchUserDialog_Init,
                cancelCallback: SwitchUser_Close
            };
            $.showControlDialog(options);
        }

I want to know how to encode my userId in the SwitchUser_Click method and decode it when its called. Or maybe there is some other way to do this . Thank you

javascript – Control zoom level when using geolocate.trigger() in mapbox gl js

I am using mapbox-gl in a react app to render an interactive map. On map load, I want to center the map on the user’s location while keeping the current level of zoom. Centering on the user’s location works fine with geolocate.trigger(); but the map automatically zooms way out to the continent level. Here is a simplified version of the map component of the app. I start by setting a hard-coded center point in New York which works fine, and then when trigger() runs, it gets zoomed way out. I’ve tried fiddling with all the properties of the geolocate object, but none of them has any effect on the zoom that trigger() goes to, and trigger doesn’t seem to take any arguments. Note that I’ve had to remove my mapboxgl.accessToken for security reasons.
As a side note, I’m also trying to get rid of the larger blue location confidence circle but I also can’t seem to do that despite setting showAccuracyCircle: false. Any mapbox tips?

React component:

import React from 'react';
import mapboxgl from 'mapbox-gl';
import './map.css';

mapboxgl.accessToken = 'ACCESS_TOKEN_STRING_GOES_HERE';

export class Map extends React.Component {
  constructor(props) {
  super(props);
    this.state = {
      lng: -73.9392,
      lat: 40.8053,
      zoom: 17.5
    };
  }

  componentDidMount() {
    const map = new mapboxgl.Map({
      container: this.mapContainer,
      style: 'mapbox://styles/mapbox/streets-v11',
      center: (this.state.lng, this.state.lat),
      zoom: this.state.zoom
    });

    const geolocate = new mapboxgl.GeolocateControl({
      container: this.geolocateContainer,
      positionOptions: {enableHighAccuracy: true},
      fitBoundsOptions: {linear: true, maxZoom: 10},
      trackUserLocation: true,
      mapboxgl: mapboxgl,
      showAccuracyCircle: false
      })

    map.on('load', () => {
      geolocate.trigger();
    });

    map.addControl(geolocate);

  }

  render() {
    return (
      <div>
        <div ref={element => this.geolocateContainer = element} className='mapButtons' />
        <div ref={el => this.mapContainer = el} className='mapContainer' />
      </div>
    )
  }
}
