一个接一个地淡入LI，然后重定向

Question

我需要淡入列表，然后等待几秒钟然后重定向到新页面。

这是我为了逐渐消失而产生的。如何在此结尾添加延迟，然后重定向？

    function fadeLi(elem) {
        elem.fadeIn(800, function() {
            fadeLi($(this).next().delay(900));
        });

    }

    fadeLi( $('#welcome li:first'));

感谢您的帮助。

很好的递归。这允许您检查jQuery对象的长度，以检测您已用尽列表项。

function fadeLi(elem) {
    // elem is a jQuery object which support length property
    if (elem.length === 0){
        // we are out of elements so we can set the location change
        setTimeout(function(){
            // set the window location to whatever url you like
            window.location = 'https://www.where.ever/you/are/taking/the/user';
        // adjust the timeout in milliseconds
        }, 900);
        // in this case you no longer want to recursively call so return
        return;
    }
    elem.fadeIn(800, function() {
        // note: I don't think delay call has any impact here.
        fadeLi($(this).next().delay(900));
    });

}

fadeLi( $('#welcome li:first'));
