我正在尝试使用Tumblr API从我的不同tumblogs收集帖子。我使用jquery tumblr plugin来做到这一点，但每个tumblog的结果都是分开的。我想将这个结果收集到一个数组中，而不是在html中渲染这个数据以排序日期...有人可以告诉我一个方向继续吗？如何使用jquery多次调用api并将结果收集到数组中？

您将需要修改jquery tumblr插件以具有一些回调函数。
尝试更换与此插件的内容...
你需要写一些回调函数和创建tumblr例如像这样...
var myResults = new Array();
var successCount = 0;
function tumblr_OnSuccess(posts) {
$(posts).children().each(function (i, item) {
myResults.push($(item).html());
});
successCount++;
if (successCount == 6) {
var d = $('<div></div>');
$(myResults).each(function (i, item) {
d.append(item);
});
$('body').append(d);
}
}
$(document).ready(function() {
$('<div></div>').tumblr({ url: 'http://kittenskittenskittens.tumblr.com', onSuccess: tumblr_OnSuccess });
$('<div></div>').tumblr({ url: 'http://kittenskittenskittens.tumblr.com', onSuccess: tumblr_OnSuccess });
$('<div></div>').tumblr({ url: 'http://kittenskittenskittens.tumblr.com', onSuccess: tumblr_OnSuccess });
$('<div></div>').tumblr({ url: 'http://kittenskittenskittens.tumblr.com', onSuccess: tumblr_OnSuccess });
$('<div></div>').tumblr({ url: 'http://kittenskittenskittens.tumblr.com', onSuccess: tumblr_OnSuccess });
$('<div></div>').tumblr({ url: 'http://kittenskittenskittens.tumblr.com', onSuccess: tumblr_OnSuccess });
});
这里是修改jQuery Tumblr Plugin
