所以我试图通过附加渲染的部分来实现无限滚动到Masonry,而不是附加div。附加一个div - 这正是Paul Irish的Infinite Scroll jQuery plugin的工作方式。我曾经使用它,但现在它对我没用,因为我想要添加部分代替。您可能会感到困惑,但我会尝试清除与代码的混淆:
masonry.js
$scope.submit = function(username){
alert(username)
}
pagination.js
var $container = $('.postindex');
$container.imagesLoaded(function (){
$container.masonry({
itemSelector: '.posts-wrapper',
isFitWidth: true,
percentPosition: true
});
});
index.html.haml
$( document ).ready(function() {
if ($('#infinite-scrolling').size() > 0) {
$(window).on('scroll', function() {
var more_posts_url;
more_posts_url = $('.pagination a.next_page').attr('href');
if (more_posts_url && $(window).scrollTop() > $(document).height() - $(window).height() - 60) {
$('.pagination').html('<img src="/assets/ajax-loader.gif" alt="Loading..." title="Loading..."/>');
$.getScript(more_posts_url);
}
});
}
});
_post.html.haml (摘录)
.postindex.transitions-enabled.infinite-scroll.page
.postin
-@posts.each do |post|
= render 'posts/post', post: post
#infinite-scrolling
= will_paginate @posts
因此,在这种情况下,我不想附加.posts-wrapper
.post
.image.center-block
%a{id: "imageurl_#{post.id}", href: "/", "data-gallery": ""}
= cl_image_tag(post.image.full_public_id, quality:"auto", fetch_format:"auto", width:640, crop: "scale", class: "img-responsive")
div,而是追加整个posts-wrapper
部分。这正是我在实施Masonry之前编写无限滚动代码的原因:
index.js.erb的
post
这当然不适用于砌体(附加项目与现有项目重叠)。现在我该如何让它发挥作用?
如果您想知道为什么我需要附加部分而不是div,我在$('.postin').append('<%= j render @posts %>');
<% if @posts.next_page %>
$('.pagination').replaceWith('<%= j will_paginate @posts %>');
<% else %>
$(window).off('scroll');
$('.pagination').remove();
<% end %>
末尾有一段脚本,我需要确保每次帖子都是加载。这是完整的文件:
_post.html.haml (完整)
_post.html.haml
其中.posts-wrapper
.post
.image.center-block
%a{id: "imageurl_#{post.id}", href: "/", "data-gallery": ""}
= cl_image_tag(post.image.full_public_id, quality:"auto", fetch_format:"auto", width:640, crop: "scale", class: "img-responsive")
:javascript
if ($(window).width() <= 800){
$("#imageurl_#{post.id}").attr("href", '#{escape_javascript( render :partial => 'posts/imageurl800', :locals => {:post => post })}');
}
else if ($(window).width() <= 1200) {
$("#imageurl_#{post.id}").attr("href", '#{escape_javascript( render :partial => 'posts/imageurl1200', :locals => {:post => post })}');
}
else if ($(window).width() <= 1600) {
$("#imageurl_#{post.id}").attr("href", '#{escape_javascript( render :partial => 'posts/imageurl1600', :locals => {:post => post })}');
}
else {
$("#imageurl_#{post.id}").attr("href", '#{escape_javascript( render :partial => 'posts/imageurl1920', :locals => {:post => post })}');
}
是:
_imageurl800.html.haml
和= cl_image_path(post.image.full_public_id, width:800, crop:"scale", class:"img-responsive")
是:
_imageurl1200.html.haml
等等。
基本上它正在做的是,每次加载帖子时,它都会检查浏览器的宽度,并根据它以特定大小加载图库(= cl_image_path(post.image.full_public_id, width:1200, crop:"scale", class:"img-responsive")
)中的图像点击时。我希望我清楚。如果有更好的方法来解决整个问题,那么请建议。谢谢!

好的,几个小时后......
var $postbox = $('<%= j render @posts %>');
var $container = $('.postindex');
$postbox.imagesLoaded(function (){
$container.append.($postbox).masonry('appended', $postbox);
});
<% if @posts.next_page %>
$('.pagination').replaceWith('<%= j will_paginate @posts %>');
<% else %>
$(window).off('scroll');
$('.pagination').remove();
<% end %>
这对你有用。

尝试了干燥方法,它解决了我的问题。我从部分中删除了脚本,而是创建了一个js函数来搜索和替换URL中的文本。例如:
<强> _post.html.haml 强>
function urlhelper() {
$("a.post_url").each(function(){
var str = $(this).attr('href')
if ($(window).width() <= 800) {
var txt = str.replace("w_640","w_800");
} else if ($(window).width() <= 1200) {
var txt = str.replace("w_640","w_1200");
} else if ($(window).width() <= 1600) {
var txt = str.replace("w_640","w_1600");
} else {
var txt = str.replace("w_640","w_1920");
}
$(this).attr('href', txt);
});
}
$( document ).ready(function() {
urlhelper();
});
$( document ).ajaxComplete(function() {
urlhelper();
});
<强> masonry.js 强>
package sso.client;
import java.security.Principal;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.security.oauth2.client.EnableOAuth2Sso;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
@EnableAutoConfiguration
@Configuration
@EnableOAuth2Sso
@RestController
public class App {
@RequestMapping("/")
public String home(Principal user) {
return "Hello " + user.getName();
}
public static void main(String[] args) {
new SpringApplicationBuilder(App.class)
.properties("spring.config.name=client").run(args);
}
}
这解决了我的问题,但我仍然想知道是否可以通过渲染部分来为砌体添加无限滚动。所以如果你知道答案,请不要犹豫,让我知道!

这可能会有所帮助:
http://masonry.desandro.com/methods.html#appended
虽然jQuery可以使用.append()添加HTML字符串,但是附加的Mason不能。使用jQuery ajax方法(如$ .get()或$ .ajax())添加内容时,请在jQuery对象中包装HTML内容字符串,以便在附加时使用它。
// does not work
$.get( 'page2', function( content ) {
// HTML string added, but items not added to Masonry
$grid.append( content ).masonry( 'appended', content );
});
// does work
$.get( 'page2', function( content ) {
// wrap content in jQuery object
var $content = $( content );
// add jQuery object
$grid.append( $content ).masonry( 'appended', $content );
});
