Question

我有一个图像网格，我希望一次一个地闪烁一次。几年前，我在旧网站上使用了以下代码，并希望重用代码，但我无法在新网站上使用它。

$('document').ready(function() {

    var myArray = ["img.square1","img.square2","img.square3","img.square4","img.square5","img.square6","img.square7","img.square8","img.square9","img.square10","img.square11","img.square12","img.square13","img.square14","img.square15"];

    console.log(myArray)
    var count = 15;
    function counter() {
        if(count < 16 && count > -1){
            $(myArray[count]).fadeTo(100, 0.1, function(){
                $(myArray[count]).fadeTo(100, 0.7, function(){
                    $(myArray[count]).fadeTo(200, 0.5, function(){
                        $(myArray[count]).fadeTo(500, 1);
                        count--
                console.log(count);
                    });                                      
                });

            });

        }else{
            clearInterval(myInterval);  
            //console.log("interval cleared");
        }
    }
    //counter();
    try{
        counter();
        alert('I guess you do exist');
    }
    catch(e){
            alert('An error has occurred: '+e.message);
    }

    console.log(counter());
    var myInterval = setInterval(counter(), 1100);
});

您可以使用.fadeTo()和setInterval()回调代替function counter(selector) { return $(selector).queue("images", $.map($(selector), function(image) { // `next` is a reference to the next function in `queueName`: `"images"` return function(next) { return $(image).fadeTo(100, 0.1, function() { $(this).fadeTo(100, 0.7, function() { $(this).fadeTo(200, 0.5, function() { $(this).fadeTo(500, 1, next); }); }); }); } })).dequeue("images").promise("images") } counter("img[class^=square]") .then(function() { console.log("done", this) })
