I have a password change code on my page. How do I do with javascript to compare if the new password entered in the two fields are equal? Here is my current code: 

<!-- Modal 4 -->
    <div class="modal fade" id="password" role="dialog" data-backdrop="false" style=" background: rgba(0,0,0,0.5);">

Try this way 

    <head>
    <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script></head><inputtype="password" id="senha1" />
    <input type="password" id="senha2" />

 <button type="button" onclick="teste()">Valida</button>

    <script>
    function teste(){
    var senha1 = $('#senha1').val();
    var senha2 = $('#senha2').val();
    if(senha1 == senha2){
    alert('As senhas são iguais');
    }else{
    alert('As senhas são diferentes');
    }
    }
    <script>
