我不断收到以下错误，但我找不到有关其含义的文档。我知道它涉及严格的 javascript 格式，我想通过遵守格式来解决它。

JSCS: Operator / should stick to following expression.

//Slow Scroll
    if ( window.addEventListener ) window.addEventListener('DOMMouseScroll', wheel, false);
    window.onmousewheel = document.onmousewheel = wheel;

    function wheel(event) {

        var delta = 0;
        if ( event.wheelDelta ) delta = event.wheelDelta / 120;
        else if ( event.detail ) delta = -event.detail / 3;

        handle ( delta );
        if ( event.preventDefault ) event.preventDefault();
        event.returnValue = false;

    }

    function handle(delta) {

        var time = 500,
        distance = 300;

        $( 'html, body' ).stop().animate(
            {
            scrollTop: $( window ).scrollTop() - ( distance * delta )
            },
        time);

    }

最佳答案

要遵守规则，您只需重写 event.wheelDelta/120 和以下行，以便 / 遵循以下表达式:event.wheelDelta/120。

    if ( event.wheelDelta ) delta = event.wheelDelta /120;
    else if ( event.detail ) delta = -event.detail /3;

disallowSpaceAfterBinaryOperators: true 行导致了这一点。您可以在此处查看文档:disallowSpaceAfterBinaryOperators .
