我通过API / Json获得Flickr画廊。我的代码存在的问题是,我获取的图片库有30张图片,但是此代码段如下:
$.each(data.album.content,function (index,content)
{
album_container.append(column);
[...]
}
仅将一个
<div>
追加到容器,而不是30,但是以正确的方式将30 a/img
追加到此唯一的column
。我不知道为什么以及如何解决它。感谢您的帮助!
var album_container = $('div#album');
function callGetAjax(url)
{
return $.get(url,{});
}
function getAlbum(feed_url)
{
callGetAjax(absolute_path+'/feed/'+feed_url)
.success(function(data)
{
})
.error(function(xhr, statusText)
{//console.log(statusText);
})
.done(function(data)
{
var loaded = 0;
album_title = data.album.album_title;
$('h1#gallery-title').html(album_title);
var column = $('<div class="col-xs-12 col-sm-6 col-md-3 col-lg-2"></div>');
$.each(data.album.content,function (index,content)
{
album_container.append(column);
$('<a/>')
.append($('<img class="img-responsive">').prop('src', content.photo))
.prop('href', content.target)
.prop('title', content.title)
.attr('data-gallery', '')
.appendTo(column)
.colorbox({rel:'gallery', speed:0, maxWidth:'95%', maxHeight:'95%'});
});
});
}
当前HTML结果:
<div class="col-xs-12 col-sm-6 col-md-3 col-lg-2">
<a href=".."><img src="..." /></a>
<a href=".."><img src="..." /></a>
<a href=".."><img src="..." /></a>
[...]
</div>
我需要的HTML:
<div class="col-xs-12 col-sm-6 col-md-3 col-lg-2">
<a href=".."><img src="..." /></a>
</div>
<div class="col-xs-12 col-sm-6 col-md-3 col-lg-2">
<a href=".."><img src="..." /></a>
</div>
<div class="col-xs-12 col-sm-6 col-md-3 col-lg-2">
<a href=".."><img src="..." /></a>
</div>
[...]
最佳答案
请记住,当文档中已经存在.append()
节点时,它将在DOM树周围移动HTML节点。就您而言,您已声明:
var column = $('<div class="col-xs-12 col-sm-6 col-md-3 col-lg-2"></div>')
…在
$.each()
循环之外,因此导致它在album_container
内部反复移动,而不是像您期望的那样被克隆。因此,您要做的是在循环中声明它,以使实例不在循环范围之内:var album_container = $('div#album');
function callGetAjax(url)
{
return $.get(url,{});
}
function getAlbum(feed_url)
{
callGetAjax(absolute_path+'/feed/'+feed_url)
.success(function(data)
{
})
.error(function(xhr, statusText)
{//console.log(statusText);
})
.done(function(data)
{
var loaded = 0;
album_title = data.album.album_title;
$('h1#gallery-title').html(album_title);
$.each(data.album.content,function (index,content)
{
// Creates a new column for every image element
var column = $('<div class="col-xs-12 col-sm-6 col-md-3 col-lg-2"></div>'),
item = $('<a/>')
.append($('<img class="img-responsive">').attr('src', content.photo))
.attr('href', content.target)
.attr('title', content.title)
.attr('data-gallery', '')
.appendTo(column)
.colorbox({rel:'gallery', speed:0, maxWidth:'95%', maxHeight:'95%'});
// Append column instance to the album container
album_container.append(column);
});
});
}
如果您还在寻找代码审查,我是否建议您从
jqXHR.success()
和jqXHR.error()
方法过渡?不推荐使用它们,而推荐使用jqXHR.done()
和jqXHR.fail()
方法。使用promise,我们的骨干如下所示:var album_container = $('div#album');
function callGetAjax(url)
{
return $.get(url,{});
}
function getAlbum(feed_url)
{
// Store returned promise from $.get() in a variable
var ajaxCall = callGetAjax(absolute_path+'/feed/'+feed_url);
// Now we listen to the promise
ajaxCall
.done(function(data) {
var loaded = 0;
album_title = data.album.album_title;
$('h1#gallery-title').html(album_title);
$.each(data.album.content,function (index,content)
{
var column = $('<div class="col-xs-12 col-sm-6 col-md-3 col-lg-2"></div>'),
item = $('<a/>')
.append($('<img class="img-responsive">').attr('src', content.photo))
.attr({
'href': content.target,
'title': content.title,
'data-gallery': ''
})
.appendTo(column)
.colorbox({rel:'gallery', speed:0, maxWidth:'95%', maxHeight:'95%'});
album_container.append(column);
});
})
.fail(function(xhr, statusText) {
// Log error
// console.log(statusText);
});
}
