setTimeout问题

我正在开发一个网站,其中包含两个横幅 - 一个用于移动,一个用于桌面。我已经有两个横幅,但似乎存在两个单独的javascript文件冲突的问题,因为当包含桌面横幅javascript文件时移动横幅无法正常工作。 现在我已经缩小了它,并认为桌面javascript文件中的setTimeout导致问题,因为当我删除该代码时,移动横幅正常工作。 要显示这是移动横幅的javascript代码(问题出在prev / next按钮的click事件中):

//Add click events to buttons
$('.js-showcase-next').click(function(event) {
    event.preventDefault();

    if ($(':animated').length) {
        return false;
    } else {
        // Clear the interval, animate the banner and then restart the interval
        clearInterval(banner_interval);
        bannerSwitch(banner_list, false, false);
        banner_interval = setInterval(function() {
            bannerSwitch(banner_list);
        }, wait_time);
    }

});

$('.js-showcase-prev').click(function(event) {
    event.preventDefault();

    if ($(':animated').length) {
        return false;
    } else {
        // Clear the interval, animate the banner and then restart the interval
        clearInterval(banner_interval);
        bannerSwitch(banner_list, true, false);
        banner_interval = setInterval(function() {
            bannerSwitch(banner_list);
        }, wait_time);
    }

});

这是导致问题的桌面横幅的javascript(移除时移动横幅正常工作):

 var wait = setInterval(function() {
     if (!$(currentBanner, loading).is(":animated")) {
         clearInterval(wait);
         loading.stop().fadeOut(300, function() {
             setTimeout(function() {

                 bannerInit();
             }, 800);
             startInterval();
             if (initialLoad) {
                 initialLoad = false;
                 next.slideDown();
                 previous.slideDown();
             }
         });
     }
 }, 200);

似乎setTimeout引起了问题,但我不明白为什么(它们是两个单独的javascript文件)。任何人都可以解决一些问题并且可能知道如何解决它?

更新 这是bannerInit的代码

function bannerInitControls() {
    previous.bind("click", function() {
        $(navigationSelector + currentIndex).removeClass(navigationSelectedClass);
        if (currentIndex == 0) {
            currentIndex = bannerCount;
        } else {
            currentIndex--;
        }
        $(navigationSelector + currentIndex).addClass(navigationSelectedClass);
        bannerLoad(currentIndex);
    });
    previous.bind("mouseenter", function() {
        $("#banner-nav-prev").stop().delay(300).show();
    });
    previous.bind("mouseleave", function() {
        $("#banner-nav-prev").stop().delay(300).hide();
    });
    next.bind("click", function() {
        $(navigationSelector + currentIndex).removeClass(navigationSelectedClass);
        if (currentIndex + 1 < banners.length) {
            currentIndex++;
        } else {
            currentIndex = 0;
        }
        $(navigationSelector + currentIndex).addClass(navigationSelectedClass);
        bannerLoad(currentIndex);
    });
    next.bind("mouseenter", function() {
        $("#banner-nav-next").stop().delay(300).show();
    });
    next.bind("mouseleave", function() {
        $("#banner-nav-next").stop().delay(300).hide();
    });

}

function bannerInitNavigation(index) {
    for (var i = 0; i <= bannerCount; i++) {
        var listItemClass = 'banner-nav-' + i;
        var listItemSelector = listItemClass;
        if (i == index) {
            listItemClass += ' banner-nav-current';
        }
        var listItem = '<li class="' + listItemClass + '"></li>'
        $(".banner-nav-list").append(listItem);
    }
}

在每个javascript文件中,将代码包装在

$(function(){

...your code here

});

更新: 如果检测到移动设备,则只需加载移动横幅脚本,而不是加载两个脚本,否则加载桌面版本:

var isMobile = false; //initiate as false
// device detection

if(isMobile){
    //load the mobile banner script
}else{
    //load the desktop banner script
}

这种方法的缺点是,如果新的移动设备问世,您需要更新此代码段。

另一种方法是获取屏幕大小,如下面链接中的第二个答案中所述。 来源:What is the best way to detect a mobile device in jQuery?
