You can make the type attribute of your button as "button". Some browsers act like submit if type is not specified.

    <button class="btn-enter-panel" onclick="getRemoteName()" type="button">enter <i class="fa fa-long-arrow-right"></i></button>


>  Always specify the type attribute for a <button> element. Different
> browsers use different default types for the <button> element.
