我正在尝试使用 Oracle Jet 组件构建一个导航栏,因为我担心我的代码的模块化,所以我正在为我的导航栏提供来自我使用 requireJS 加载的另一个模块的所需信息。执行时出现此错误Message: Unable to process binding "foreach: function (){return pages }"
Message: pages is not defined
我的第一个猜测(使用断点之后)是绑定是在我的变量页面获取适当的数据之前完成的。如果是这种情况,我如何确保仅在我的变量正确初始化后才打印导航栏,如果不是,我做错了什么?
这是我的代码:
模板
<div id="topbar">
<div class="oj-sm-condense" data-bind="ojComponent:{
component: 'ojNavigationList',
selection: currentPage,
navigationLevel: 'application',
edge: 'top'}" >
<ul id="pills" >
<!-- ko foreach: pages -->
<li data-bind="attr:{id:id}">
<a data-bind="attr:{href:url}">
<p data-bind="text:label"></p>
</a>
</li>
<!-- /ko-->
</ul>
</div>
</div>
模板的 JS
define(['ojs/ojcore', 'knockout', 'ojs/ojnavigationlist'
], function (oj, ko) {
function homeContentViewModel(data) {
var self = this;
require(['banner/' + data], function (pages) {
self.pages=pages;
});
}
return homeContentViewModel;
});
数据模块
define(['ojs/ojcore', 'knockout', 'ojs/ojnavigationlist'
], function (oj, ko) {
this.currentPage=ko.observable('Page1');
var self = this;
var pages = [
{id: "id1", label:"Page1", url: "#"},
{id: "id2", label:"Page2", url: "#"},
{id: "id3", label:"Page3", url: "#"},
{id: "id4", label:"Page4", url: "#"},
{id: "id5", label:"Page5", url: "#"},
{id: "id6", label:"Page6", url: "#"},
];
return pages;
});
