У меня есть список элементов карты, и каждая из этих карт содержит некоторую информацию. С опцией «загрузить больше» я пытаюсь загрузить только три элемента карты одновременно, и по умолчанию изначально загружаются только два элемента. Ниже мой файл просмотра:
(function() {
var __extends = function(child, parent) { for (var key in parent) {
if (__hasProp.call(parent, key)) child[key] = parent[key]; } function
ctor() { this.constructor = child; } ctor.prototype = parent.prototype;
child.prototype = new ctor(); child.__super__ = parent.prototype;
return child; },
__hasProp = {}.hasOwnProperty;
TalentCardNew.Views.CertificationCard = (function(_super) {
__extends(CertificationCard, _super);
function CertificationCard() {
return CertificationCard.__super__.constructor.apply(this, arguments);
}
CertificationCard.prototype.template = JST['talent_card_new/templates/common/certification_card'];
CertificationCard.prototype.className = 'certification-container';
CertificationCard.prototype.events = {
'click .listCertificatesContainer': 'showMoreCertificates'
};
CertificationCard.prototype.initialize = function(options) {
if (options == null) {
options = {};
}
this.view_type = options.view_type;
this.card_data = new Backbone.Collection();
this.card_data.add(new Backbone.Model({
name: "Accounting Qualification Excellence",
place: "Accounting Institue",
valid_till: "Dec 14, 2018"
}));
this.card_data.add(new Backbone.Model({
name: "Accounting Qualification Excellence",
place: "Accounting Institue",
valid_till: "Dec 14, 2018"
}));
this.card_data.add(new Backbone.Model({
name: "Accounting Qualification Excellence",
place: "Accounting Institue",
valid_till: "Dec 14, 2018"
}));
this.card_data.add(new Backbone.Model({
name: "Accounting Qualification Excellence",
place: "Accounting Institue",
valid_till: "Dec 14, 2018"
}));
this.card_data.add(new Backbone.Model({
name: "Accounting Qualification Excellence",
place: "Accounting Institue",
valid_till: "Dec 14, 2019"
}));
this.card_data.add(new Backbone.Model({
name: "Accounting Qualification Excellence",
place: "Accounting Institue",
valid_till: "Dec 14, 2018"
}));
this.card_data.add(new Backbone.Model({
name: "Accounting Qualification Excellence",
place: "Accounting Institue",
valid_till: "Dec 14, 2018"
}));
return this.card_data.add(new Backbone.Model({
name: "Accounting Qualification Excellence",
place: "Accounting Institue",
valid_till: "Dec 14, 2019"
}));
};
CertificationCard.prototype.render = function() {
$(this.el).html(this.template({
view_type: this.view_type,
card_data: this.card_data
}));
if (this.view_type === 'my_profile') {
this.renderModal();
}
this.renderLoadMore();
return this;
};
CertificationCard.prototype.renderModal = function() {
var popup_view;
popup_view = new TalentCardNew.Views.AddCertification();
return $(this.el).find('#modalContainer').html(popup_view.render().el);
};
CertificationCard.prototype.renderLoadMore = function() {
if ((this.view_type === 'my_profile' && this.card_data.length > 2) || (this.card_data.length > 3)) {
return $(this.el).find('.listCertificatesContainer').removeClass('hide');
}
};
return CertificationCard;
})(Backbone.View);
}).call(this);
Также мой код Haml ниже:
- now = new Date()
- if @view_type == 'my_profile'
%button.certification-card.add-certification-card{"data-target" =>
"#certificationModal", "data-toggle" => "modal"}
%i.avatar--icon.fa.fa-plus-circle
%elabel= ECL.t('add', default_value: "Add")
- _.each @card_data.models, (data) =>
- expire_date = "#{data.get('valid_till')}"
- actual_date = new Date(expire_date)
.certification-card
.avatar--icon.fa.fa-users
.details
.title= "#{data.get('name')}"
.caption= "#{data.get('place')}"
- if actual_date < now
.meta-text= "Valid Till: #{data.get('valid_till')}"
- else
.meta-text= "Expired On: #{data.get('valid_till')}"
%button.btn-more.listCertificatesContainer.hide

#modalContainer
Здесь я пытаюсь отобразить все две сертификационные карты по умолчанию и загружать остальные три за один раз только по щелчку загрузки. Помощь будет признательна
