Question

我还在学习如何使用jQuery，我有这个脚本可以平滑滚动到我页面上的锚点。我希望它在开始滚动之前等待一秒钟，因为我有一个需要关闭的菜单。我假设我需要使用setTimeout()函数，但无法弄清楚如何在我的代码中正确实现它。

＆＃13;

<script>

  $(document).ready(function(){
	$('a[href^="#"]').on('click',function (e) {
	    e.preventDefault();

	    var target = this.hash,
	    $target = $(target);

	    $('html, body').stop().animate({
	        'scrollTop': $target.offset().top - 2
	    }, 900, 'easeInOutExpo', function () {
	        window.location.hash = target;
	    });
	});
});

</script>

Answer 1

在超时中包裹动画：

setTimeout(function() {
    $('html, body').stop().animate({
        'scrollTop': $target.offset().top - 2
    }, 900, 'easeInOutExpo', function () {
        window.location.hash = target;
    });
}, 1000);

Answer 2

您需要在事件发生后点击后添加。像这样：

$(document).ready(function(){
    $('a[href^="#"]').on('click',function (e) {
        e.preventDefault();
        // a settimeout is a function with two parameters: a function to execute, 
        // and a time to delay. So whatever you want to do, you can wrap in what is
        // called an 'anonymous' function. Used once, then forgotten about.
        setTimeout(function(){
            var target = this.hash,
            $target = $(target);

            $('html, body').stop().animate({
                'scrollTop': $target.offset().top - 2
            }, 900, 'easeInOutExpo', function () {
                window.location.hash = target;
            });
        }, 1000);
    });
});
