我在我的主干应用程序链接中创建了来自 json 的两个 id 的问题。之前我在模板中只是变量 id。我的链接是.../tables/
在点击表格之后.../table:id/
但在表格中是下一个菜单,我需要在点击两个数组中的这个菜单 id 后,就像.../table:id/menu:id
会显示类别视图....
我的第一个表格模板
<script type="text/template" id="table-template">
<% _.each(tables, function(table) { %>
<li class="tableli" data-table_id="<%= table.get('id') %>">
<div class="obrazok"></div>
<%= table.get('name') %>
</li>
<% }); %>
</script>
第一个表视图
var TablesView = Backbone.View.extend({
initialize:function () {
this.render();
},
tagName: "ul",
events: {
"click li.tableli" : "openMenuItem"
},
openMenuItem: function(e){
currentLink = $(e.currentTarget);
tableId = currentLink.data('table_id');
app.navigate("table" + tableId + "/menus", true);
console.log("table/" + tableId + "/menus");
},
render:function () {
var that = this;
var tables = new Tables();
tables.fetch({
success: function (tables) {
var template = _.template($('#table-template').html(), {tables: tables.models});
that.$el.html(template);
}
})
}
});
好的,单击其中一个 li 后,我想拥有类似的链接...table:id/
并仅打开菜单视图
我的菜单视图:
<script type="text/template" id="menu-template">
<% _.each(menus, function(menu) { %>
<li class="menucls" data-menu_id="<%= menu.get('id') %>">
<%= menu.get('name') %>
</li>
<% }); %>
</script>
菜单视图:
var MenusView = Backbone.View.extend({
initialize:function () {
this.render();
},
tagName: "ul",
events: {
"click li.menucls" : "openMenuItem"
},
openMenuItem: function(e){
currentLink = $(e.currentTarget);
menuId = currentLink.data('menu_id');
tableId = currentLink.parent().data('table_id');
app.navigate("table" + tableId + "/menu" + menuId + "/", true);
console.log("menuId: " + menuId );
console.log("tableId: " + tableId );
},
render:function () {
var that = this;
var menus = new Menus();
menus.fetch({
success: function (menus) {
var template = _.template($('#menu-template').html(), {menus: menus.models});
that.$el.html(template);
}
})
}
});
还有我的目标....点击后我需要像这样的链接.../table:id/menu:id/
有我的 json 和集合....
表.json
[
{"name": "Table 1","stts": "redstts","id": 1},
{"name": "Table 2","stts": "redstts","id": 2},
{"name": "Table 3","stts": "redstts","id": 3},
{"name": "Table 4","stts": "redstts","id": 4},
{"name": "Table 5","stts": "redstts","id": 5}
]
菜单.json
[
{"name": "Menu 2","id": 1},
{"name": "Menu 2","id": 2}
]
var Table = Backbone.Model.extend({
defaults: {"name": "Table unahmed"}
});
var Tables = Backbone.Collection.extend({
url: 'api/tables.json',
model: Table
});
var Menu = Backbone.Model.extend({
defaults: {"name": "Menu unahmed"}
});
var Menus = Backbone.Collection.extend({
url: 'api/menus.json',
model: Menu
});
我的主要js
var AppRouter = Backbone.Router.extend({
routes: {
"" : "tables",
"orders" : "orders",
"tables" : "tables",
"table:id/menus" : "menus",
"products" : "products",
"table:id/menu:id/" : "categories"
},
initialize: function () {
this.headerView = new HeaderView();
$('.header').html(this.headerView.el);
},
tables: function () {
if (!this.TablesView) {
this.TablesView = new TablesView();
}
$('#content').html(this.TablesView.el);
this.headerView.selectMenuItem('tables-menu');
},
menus: function () {
if (!this.MenusView) {
this.MenusView = new MenusView();
}
$('#content').html(this.MenusView.el);
this.headerView.selectMenuItem('menus-menu');
},
categories: function (tableId, menuId) {
if (!this.CategoriesView) {
this.CategoriesView = new CategoriesView();
}
$('#content').html(this.CategoriesView.el);
this.headerView.selectMenuItem('categories-menu');
},
products: function () {
if (!this.ProductsView) {
this.ProductsView = new ProductsView();
}
$('#content').html(this.ProductsView.el);
this.headerView.selectMenuItem('products-menu');
}
});
utils.loadTemplate(['HeaderView'], function() {
app = new AppRouter();
Backbone.history.start();
});
我仍然尝试在没有结果的情况下使函数事件萌芽...事件是函数,但在链接中是
#tableundefined/menu1/
我非常感谢每一个答案。问候马克罗马特!
