是否可以将 .live() 函数添加到 getJson 调用中？

我有这段代码：

问题是，我无法将“active”类添加到 mac div 内的 getJson 图像中。在这里集成实时功能会有帮助吗？

$.getJSON("http://api.flickr.com/services/feeds/photos_public.gne?id=59597329@N08&lang=en-us&format=json&jsoncallback=?", function(data){
    $.each(data.items, function(i,item){
        $("<img src='" + item.media.m + "'></img>").appendTo("#mac");
    });
});

$("#mac img:first").addClass('active');

function slideSwitch() {
var $active = $('#mac img.active');

if ( $active.length == 0 ) $active = $('#mac img:last');

var $next =  $active.next().length ? $active.next()
    : $('#mac img.active');

$active.addClass('last-active');

$next.css({opacity: 0.0})
    .addClass('active')
    .animate({opacity: 1.0}, 1000, function() {
        $active.removeClass('active last-active');
    });
}

$(function() {
    setInterval( slideSwitch, 5000 );
});

I have this code:

The problem is, i cant add the 'active' class to the getJson's images inside the mac div. Would integrating a live function here help at all?

$.getJSON("http://api.flickr.com/services/feeds/photos_public.gne?id=59597329@N08&lang=en-us&format=json&jsoncallback=?", function(data){
    $.each(data.items, function(i,item){
        $("<img src='" + item.media.m + "'></img>").appendTo("#mac");
    });
});

$("#mac img:first").addClass('active');

function slideSwitch() {
var $active = $('#mac img.active');

if ( $active.length == 0 ) $active = $('#mac img:last');

var $next =  $active.next().length ? $active.next()
    : $('#mac img.active');

$active.addClass('last-active');

$next.css({opacity: 0.0})
    .addClass('active')
    .animate({opacity: 1.0}, 1000, function() {
        $active.removeClass('active last-active');
    });
}

$(function() {
    setInterval( slideSwitch, 5000 );
});

你没有说出你真正想做什么。一种解决方案是将所有必须在 DOM 上运行的代码放入 Ready 处理程序中，并在数据加载后触发间隔：

function slideSwitch() {
    var $active = $('#mac img.active');
    if ( $active.length == 0 ) $active = $('#mac img:last');
    var $next =  $active.next().length ? $active.next() : $('#mac img.active');
    $active.addClass('last-active');

    $next.css({opacity: 0.0})
        .addClass('active')
        .animate({opacity: 1.0}, 1000, function() {
            $active.removeClass('active last-active');
        });
}

$(function() {
    $.getJSON("http://api.flickr.com/services/feeds/photos_public.gne?id=59597329@N08&lang=en-us&format=json&jsoncallback=?", function(data){
        $.each(data.items, function(i,item){
            $("<img src='" + item.media.m + "'></img>").appendTo("#mac");
        });
        $("#mac img:first").addClass('active');
        setInterval( slideSwitch, 5000 );
    }); 
});

You didn't say what you actually want to do. One solution would be to put all code that has to work on DOM inside the ready handler and fire the interval once the data is loaded:

function slideSwitch() {
    var $active = $('#mac img.active');
    if ( $active.length == 0 ) $active = $('#mac img:last');
    var $next =  $active.next().length ? $active.next() : $('#mac img.active');
    $active.addClass('last-active');

    $next.css({opacity: 0.0})
        .addClass('active')
        .animate({opacity: 1.0}, 1000, function() {
            $active.removeClass('active last-active');
        });
}

$(function() {
    $.getJSON("http://api.flickr.com/services/feeds/photos_public.gne?id=59597329@N08&lang=en-us&format=json&jsoncallback=?", function(data){
        $.each(data.items, function(i,item){
            $("<img src='" + item.media.m + "'></img>").appendTo("#mac");
        });
        $("#mac img:first").addClass('active');
        setInterval( slideSwitch, 5000 );
    }); 
});
