我正在尝试改进我的小主干应用程序的导航。现在我只有一些使用 html 链接的简单导航,这些链接用于 href 元素中的#path/to/page。
我遇到的是当我点击其中一个然后点击后退按钮时,页面没有正确刷新,并且 HTML 内容没有改变。所以我正在尝试将导航功能合并到我的代码中。
我遇到的问题是我找不到与我当前使用的代码布局相匹配的示例,而且我不了解 backbone 如何工作以将我发现的东西改编成有用的东西。
这是我得到的:
app.js - 从 index.html 文件调用
require.config({
baseUrl: 'js/lib',
paths: {
app: '../app',
tpl: '../tpl',
bootstrap: 'bootstrap/js/',
},
shim: {
'backbone': {
deps: ['underscore', 'jquery'],
exports: 'Backbone'
},
'underscore': {
exports: '_'
}
}
});
require([
'jquery',
'backbone',
'app/router',
], function ($, Backbone, Router) {
var router = new Router();
Backbone.history.start();
});
app/router.js - 在 app.js 中实例化
define(function (require) {
"use strict";
var $ = require('jquery'),
Backbone = require('backbone'),
WindowView = require('app/views/Window'),
breadcrumbs = {"Home": ""},
$body = "",
$content = "",
windowView = "";
return Backbone.Router.extend({
initialize: function () {
require([], function () {
$body = $('body');
windowView = new WindowView({el: $body}).render();
$content = $("#content", windowView.el);
});
},
routes: {
'' : 'home',
'profile/login(/)' : 'candidateProfileLogin',
'profile/manage(/)' : 'candidateProfileLogin',
'profile/manage/:id(/)' : 'candidateProfileHome',
'profile/manage/:id/questionnaire/:page(/)' : 'candidateProfileQuestionnaire',
'profile/manage/:id/:section(/)' : 'candidateProfileSection',
},
home: function (){
},
candidateProfileLogin: function () {
require(['app/views/CandidateLogin'], function (CandidateLoginView) {
console.log(Backbone.history.fragment);
var view = new CandidateLoginView({el: $content});
view.render();
});
},
candidateProfileHome: function (id) {
require(["app/views/Candidate", "app/models/candidate"], function (CandidateView, models) {
var candidate = new models.Candidate({id: id});
candidate.fetch({
success: function (data) {
var view = new CandidateView({model: data, el: $content});
view.render();
},
error: function (data) {
var view = new CandidateView({model: data, el: $content});
view.render();
}
});
});
},
candidateProfileSection: function (id, section) {
require(["app/views/Candidate", "app/models/candidate"], function (CandidateView, models) {
var candidate = new models.Candidate({id: id});
candidate.fetch({
success: function (data) {
var view = new CandidateView({model: data, el: $content});
view.render(section);
},
error: function (data) {
//Output the data to the console. Let the template take care of the error pages
console.log(data);
var view = new CandidateView({model: data, el: $content});
view.render();
}
});
});
},
candidateProfileQuestionnaire: function (id, page) {
require(["app/views/Candidate", "app/models/candidate"], function (CandidateView, models) {
var candidate = new models.Candidate({id: id});
candidate.fetch({
success: function (data) {
var view = new CandidateView({model: data, el: $content});
view.render(page);
},
error: function (data) {
//Output the data to the console. Let the template take care of the error pages
console.log(data);
var view = new CandidateView({model: data, el: $content});
view.render();
}
});
});
},
});
});
app/views/Candidate.js - 我正在尝试处理点击的 View
define(function (require) {
"use strict";
var $ = require('jquery'),
_ = require('underscore'),
Backbone = require('backbone'),
tpl = require('text!tpl/Candidate.html'),
template = _.template(tpl),
CandidateErrorView = require('app/views/CandidateError'),
errtpl = require('text!tpl/CandidateError.html'),
errTemplate = _.template(errtpl);
return Backbone.View.extend({
events: {
'submit #voters-guide-personalInfo': 'savePersonalInfo',
'submit #voters-guide-essay' : 'saveEssay',
'submit #voters-guide-survey' : 'saveSurvey',
'submit #voters-guide-endorsements': 'saveEndorsements',
'submit #voters-guide-photo' : 'savePhoto',
'click #table-of-contents a' : 'navTOC',
},
savePersonalInfo: function (event) {
console.log(event);
},
saveEssay: function (event) {
console.log(event);
},
saveSurvey: function (event) {
console.log(event);
},
saveEndorsements: function (event) {
console.log(event);
},
savePhoto: function(event) {
console.log(event);
},
navTOC: function (event) {
console.log(event.target);
var id = $(event.target).data('candidate-id');
var path = $(event.target).data('path');
//router.navigate("profile/manage/" + id + "/" + path, {trigger: true});
},
render: function (page) {
//Check to see if we have any errors
if (!this.model.get('error')) {
var dataToSend = {candidate: this.model.attributes};
switch(page) {
case 'personalInfo':
template = _.template(require('text!tpl/Candidate-personalInfo.html'));
break;
case 'essay':
template = _.template(require('text!tpl/Candidate-essay.html'));
break;
case 'survey':
template = _.template(require('text!tpl/Candidate-survey.html'));
break;
case 'endorsements':
template = _.template(require('text!tpl/Candidate-endorsements.html'));
break;
case 'photo':
template = _.template(require('text!tpl/Candidate-photo.html'));
break;
default:
break;
}
this.$el.html(template(dataToSend));
return this;
} else {
this.$el.html(errTemplate({candidate: this.model.attributes}));
return this;
}
}
});
});
现在,为了解决“当我按下后退按钮时页面内容没有重新加载”的问题,我一直在研究主干可用的导航功能(这:router.navigate (片段,[选项]);
)。有很多关于如何使用它的示例,但它们似乎都与我正在使用的文件设置没有任何相似之处,所以我不确定如何最好地从我的 Angular 访问此功能。如果我在 View 中包含路由器文件并实例化它的新版本,分页 b/c 它会尝试再次运行初始化函数。
我真的不知道它应该如何工作。
有人能指出我正确的方向吗?
谢谢! --丽莎
附言如果有人有更好的想法,我会洗耳恭听!
最佳答案
您应该可以访问 Backbone
对象,在该对象中,可以使用 history.navigate
函数进行导航。如果您在 trigger: true
中调用它,您将调用该路由。例如:
Backbone.history.navigate("profile/manage", { trigger: true });
关于javascript - Backbone.js 和 router.navigate,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/23918736/
