javascript - 单击并向下滚动页面上的滑入式号召性用语 div buggy

Question

我有一个 div，单击它会在右侧滑入，但如果它尚未打开或打开，我也试图让它在滚动时滑入。因此，您可以单击按钮使其滑入，或者如果在您向下滚动页面时将其关闭，它会打开，然后在几秒钟后消失，或者如果单击按钮。

我有点让它工作，但有很多错误。任何帮助将不胜感激!

HTML:

<div class="floating-form" id="contact_form">
<div class="contact-opener">CTA Box Toggle</div>    
    <div class="contact_body">

        <h3>This is a CTA Box</h3>
        <p>On click it will slide out and on scroll it will scroll out as you get down the page and then go away.</p>

        <a href="#" class="btn btn-primary btn-block"><i class="fa fa-calendar-o"></i> CTA Button</a>


    </div>
</div>

jQuery:

$(document).ready(function(){ 
    var buttonhieght = $('.contact-opener').width()-52;
    var popdiv = $('#contact_form').width();
    var _scroll = true, _timer = false, _floatbox = $("#contact_form"), _floatbox_opener = $(".contact-opener") ;
    _floatbox.css("right", "-"+ popdiv+"px"); //initial contact form position
    _floatbox_opener.css("left", "-"+ buttonhieght+"px"); //initial contact form position

    //Contact form Opener button
    _floatbox_opener.click(function(){
        if (_floatbox.hasClass('visiable')){
            _floatbox.animate({'right': '-'+ popdiv+'px'}, {duration: 300}).removeClass('visiable');
        }else{
           _floatbox.animate({"right":"0px"},  {duration: 300}).addClass('visiable');
        }
    }); 
});
$(document).on('scroll', function() {
    var popdiv = $('#contact_form').width();
    var _floatbox = $("#contact_form");
    var scrollTop = $(window).scrollTop();
    if (scrollTop > 700) {
        if (_floatbox.hasClass('visiable')){
            _floatbox.animate({'right': '-'+ popdiv+'px'}, {duration: 300}).removeClass('visiable');
        }else{
           _floatbox.animate({"right":"0px"},  {duration: 300}).addClass('visiable');

问题是滚动处理程序永远不会分离，因此 #contact_form 一直显示/隐藏，直到所有滚动事件都被“清除”。我已经更新了您的 fiddle ，使其仅在页面滚动到某个点后才尝试显示一次 #contact_form，然后删除滚动处理程序。

我认为这就是您想要的:http://jsfiddle.net/50tab7vh/3/
