我正在制作预订比较引擎，我有一个非常敏感的问题。
这笔交易是我有3-4种不同的来源来比较结果。并且每个数据提供者都有自己的API，并且在每种搜索方法中都有另一个分页，因此您可以向他们发送请求：
你基本上回来了：
所以我通过JQuery填充它们。实际上Ajax GET请求被发送到我的
www.mysite.com/search_script.php
结果填充。
让我们说：
在我们的网站上，我们需要安排好的分页。说好，我的意思是专业，所以我们不加载太多的浏览器，服务器也有太多的API查询。
我原以为我可以这样做：
如果在我的网站中我每页有10个结果的分页，那么我会查询这两个来源，并要求每页发回5个结果。
但我会遇到两类问题：
第1页返回23 of 2 2nd only 4
5 + 4,5 + 0,5 + 0 ......
两者都超过5，但是一个比第二个结束，让我们说12和5 5-5,5-0,5 / 0
...
不是一个好的解决方案......
这种情况的锻炼是什么？

，第二个是相同的......
答案 0 :(得分：0)
您需要为每个连接创建对象。
此对象将加载加载到数组的内容。它们可以表示为：
function Connection( searchQuery, callback )
{
var result = []; // use to save what you load
this.total; // total searching found
this.getResult = function( start, length, callback ){}; // it's is one of the possibilities.
// this function should verify if the content is already loaded in result[] or not. If not, load then. There is no problem of loading more then needed.
}
当你得出结论时，它应该以类似的方式工作：
var conn = new Connection( "...", objectIsWorkable ); // load the first XX results and get the total found stuff.
conn.getResult( 0, 5, whenLoaded );
完成这项工作后，你可以做你真正想要的事情：
var pageController = function( queries, callback )
{
var ITEM_PER_CONNECTION = 5;
var ITEM_PER_PAGE = 10;
var conns = []; // used to save all connections
var pages = []; // use to save the pages to be loaded
var loaded = 0;
var onLoadedCallback = callback;
var totalConnPage;
var onPageLoadedCallback;
var tempPage; // the items loaded are saved here.
var appendToTempPage = function( value )
{
for( var i in value ) tempPage.push( value[i] );
loaded++;
if( loaded == totalConnPage ) onPageLoadedCallback( tempPage );
}
this.loadPage = function( num, callback )
{
onPageLoadedCallback = callback;
loaded = 0;
tempPage = [];
totalConnPage = 0;
var current = pages[num];
for( var i = 0; i < current.length; i++ )
{
if( current[i] != null )
{
conns[i].getResult( current[i][0], current[i][1], appendToTempPage );
totalConnPage++;
}
}
}
var makePages = function()
{
// get the total
var total = 0;
var totals = [];
for( var i in conns )
{
total += conns[i].total;
totals.push( 0 );
}
// create the page list
while( total > 0 )
{
var temp = total > ITEMS_PER_PAGE ? ITEMS_PER_PAGE : total;
total -= temp;
var page = [];
var index = 0;
while( temp > 0 )
{
if( totals[index] < conns[index].total )
{
if( conns[index].total - totals[index] >= ITEM_PER_CONNECTION )
{
var next = temp > ITEM_PER_CONNECTION ? ITEM_PER_CONNECTION : temp;
page.push( [totals[index], next] );
totals[index] += next;
temp -= next;
}
else
{
var next = conns[index].total - totals[index];
next = next > temp ? temp : next;
page.push( [totals[index], next] );
totals[index] += next;
temp -= next;
}
}
else
page.push( null );
index++;
}
pages.push( page );
}
}
var inited = function()
{
pages[loaded] = 0;
loaded++;
if( loaded == conns.length )
{
makePages();
onLoadedCallback();
}
}
// init
for( var i in queries )
conns.push( new Connection( queries[i], inited ) );
}
最重要的是makePages，可能是你想要做的事情。但是你的问题有点长了，然后我再添加一些东西就不会让人感到困惑。
您可以将makePage更改为以您的方式工作。我们的想法是将所有页面内容保存在pages var。
