更改您的出版物以接受这样的pageNumber参数
Meteor.publish('posts', function (pageNumber) {
var numberOfRecordsPerPage = 10;
var skipRecords = numberOfRecordsPerPage * (pageNumber - 1);
return Post.find({
"user_id": user_id
}, {
sort: { 'cDate.timestamp': -1 }
skip: skipRecords,
limit: numberOfRecordsPerPage
});
});
在客户端，我没有过多地使用 angular-meteor。您可以使用或pageNumber在当前范围内创建属性。每当单击分页页面时更新此变量。每当更改此变量时，请使用当前页码进行订阅。this.pageNumber$scope.pageNumberpageNumber
如果它使用标准 blaze 模板，我会在这样的情况下使用响应式 var 或 session var autorun。在模板 html 中：
<template name="postsTemplate">
<ul>
<!-- you would want to do this list based on total number of records -->
<li class="pagination" data-value="1">1</li>
<li class="pagination" data-value="2">2</li>
<li class="pagination" data-value="3">3</li>
</ul>
</template>
在模板 js 中：
Template.postsTemplate.created = function () {
var template = this;
Session.setDefault('paginationPage', 1);
template.autorun(function () {
var pageNumber = Session.get('paginationPage');
Meteor.subscribe('posts', pageNumber);
});
}
Template.postsTemplate.events(function () {
'click .pagination': function (ev, template) {
var target = $(ev.target);
var pageNumber = target.attr('data-value');
Session.set('paginationPage', pageNumber);
}
});
这样，您将在客户端的任何时间点最多有 10 条记录，因此不会导致浏览器崩溃。您可能还想使用类似这样的方式限制发送给客户端的字段
Meteor.publish('posts', function (pageNumber) {
var numberOfRecordsPerPage = 10;
var skipRecords = numberOfRecordsPerPage * (pageNumber - 1);
return Post.find({
"user_id": user_id
}, {
sort: { 'cDate.timestamp': -1 }
skip: skipRecords,
limit: numberOfRecordsPerPage,
fields: {'message': 1, 'createdBy': 1, 'createdDate': 1 } //The properties inside each document of the posts collection.
});
});
最后，您将需要客户端的帖子集合中的记录总数，以显示分页链接。您可以使用不同的出版物并使用此处observeChanges官方文档中提到的概念来执行此操作
// server: publish the current size of a collection
Meteor.publish("posts-count", function () {
var self = this;
var count = 0;
var initializing = true;
// observeChanges only returns after the initial `added` callbacks
// have run. Until then, we don't want to send a lot of
// `self.changed()` messages - hence tracking the
// `initializing` state.
var handle = Posts.find({}).observeChanges({
added: function (id) {
count++;
if (!initializing)
self.changed("postsCount", 1, {count: count});
},
removed: function (id) {
count--;
self.changed("postsCount", 1, {count: count});
}
// don't care about changed
});
// Instead, we'll send one `self.added()` message right after
// observeChanges has returned, and mark the subscription as
// ready.
initializing = false;
self.added("postsCount", 1, {count: count});
self.ready();
// Stop observing the cursor when client unsubs.
// Stopping a subscription automatically takes
// care of sending the client any removed messages.
self.onStop(function () {
handle.stop();
});
});
// client: declare collection to hold count object
PostsCount = new Mongo.Collection("postsCount");
// to get the total number of records and total number of pages
var doc = PostsCount.findOne(); //since we only publish one record with "d == 1", we don't need use query selectors
var count = 0, totalPages = 0;
if (doc) {
count = doc.count;
totalPages = Math.ceil(count / 10); //since page number cannot be floating point numbers..
}
希望这可以帮助。
