Installation: npm install angular-utils-ui-breadcrumbs

Module dependencies:

var app = angular.module('myapp', ['ui.router.state.events','angularUtils.directives.uiBreadcrumbs']);

ui.router.state is used here .events module, because the uiBreadcrumbs depends on the $stateChangeSuccess event, and uiRouter recommends using the Transition hook after version 1.x. In order to be compatible with the original version, the deprecated state events are encapsulated into the stateEvent.js file. This file In the UIRouter package, so we need to introduce this file. The angularUtils.directives.uiBreadcrumbs module already depends on the ui.router module, and we do not need to introduce it again here.

The file directory structure is as follows:

<!--index.html-->
<!DOCTYPE html>
<html lang="en" ng-app="myapp" ng-strict-di>

The following is a detailed description of how to use the plug-in:

<ui-breadcrumbs displayname-property="data.displayName"
    [template-url=""]
    [abstract-proxy-property=""]>
</ui-breadcrumbs>

Copy after login

dispalyname-property: (required ), this attribute points to a certain attribute of the state configuration object when you declare the route. The value of this attribute is the value that the breadcrumbs will display under the route. If not specified, the name attribute of the state will be displayed.

template-url: (Optional) Specify the path of uiBreadcrumbs.tpl.html. This file is the template of the ui-breadcrumbs directive. If not specified, the following directory will be used by default. The following is the content of the source code:

　 var moduleName = 'angularUtils.directives.uiBreadcrumbs';
 var templateUrl = 'directives/uiBreadcrumbs/uiBreadcrumbs.tpl.html';

 /**
  * Module
  */
 var module;
 try {
  module = angular.module(moduleName);
 } catch(err) {
  // named module does not exist, so create one
  module = angular.module(moduleName, ['ui.router']);
 }

Copy after login

abstract-proxy-property: (optional), when using abstract state, we cannot transition to this state. Therefore we cannot display the breadcrumbs of this state, because clicking on an abstract state will cause an exception, so to solve this situation, we can let abstract-proxy-property point to a state config property, the value of which is When a certain state.name, that is, a certain route, needs to display the breadcrumbs of the abstract state, it will look for the state.name to replace the abstract state. As in the above example, we specified the state of home.info.
