I need to automatically set autofocus to the input contained in a modal whenever I open it. What Javascript function can I use for this?

<input type="email" class="form-control" placeholder="Informe o e-mail" value="{{cliente.getEmail()}}" name="email" id="emailCliente" required>

javascript html

  • how are you opening this modal? will depend on it!

  • By clicking a button it opens with input. I need this input to automatically receive autofocus.

  • Put every example in your question we have no way of knowing what you did there!

By the class that is in the input form-control it seems to me that you use Bootstrap. In this part in the documentation they indicate that you use the event .on('shown.bs.modal', function () { } to interact with the modal, so in your case would look like this. See the official documentation https://getbootstrap.com/docs/4.0/components/modal/

$('#myModal').on('shown.bs.modal', function () {
    $('#myInput').focus();
})

See the model working.

You can do this by adding to the event that opens the modal

function abrirModal(){
    var element = document.getElementsByName("email")[0];
    element.focus();
}

I made some corrections to the code and you can see it working here https://jsfiddle.net/c25gvj9b/
