Need to click twice to go back in history (using pushState)

Question

When the popstate event is fired and you loop through the select fields, if the condition $( this ).val() != parameterNames[index].value is satisfied, the current select value will be altered, but will also fire the change event, which, in turn, will call again the function that pushes a new state into the history. That way, if you go back in the history, you will get the same state-object.

Hence, the solution would be check if the popstate event was fired, and if so, do not call history.pushState, but, instead, history.replaceState.

function handleHistoryStates(popstateEventWasFired = false) {
    $(".chosen-select-field").each( function ( index ) {
        parameterNames[index].value = $( this ).val();
    });
    
    if (popstateEventWasFired) {
        history.replaceState(parameterNames, '', newUrl);
    } else {
        history.pushState(parameterNames, '', newUrl);
    }
}

$(".chosen-select-field").chosen().change(handleHistoryStates);


var restoreState = function(event) {
    event = event.originalEvent;
    parameterNames = event.state;
    $(".chosen-select-field").each( function ( index ) {
        if ($( this ).val() != parameterNames[index].value){
            $( this ).val(parameterNames[index].value);
            handleHistoryStates(true);
            $( this ).trigger('chosen:updated');
        }
    });
};

// Bind history events
$(window).bind("popstate",restoreState);

I guess you are Pushing the current state when you reach the state,Instead of that you Push the previous state when u reach current state.. That why when u first press the back button your poping the current state,And u need to pop the previous state and go there ...

let boxes = Array.from(document.getElementsByClassName('box'));

function selectBox(id) {
  boxes.forEach(b => {
    b.classList.toggle('selected', b.id === id);
  });
}

boxes.forEach(b => {
  let id = b.id;
  b.addEventListener('click', e => {
    history.pushState({
      id
    }, `Selected: ${id}`, `./selected=${id}`)
    selectBox(id);
  });
});

window.addEventListener('popstate', e => {
  selectBox(e.state.id);
});

history.replaceState({
  id: null
}, 'Default state', './');
