在Backbone.js中有條件地執行路由

Question

我致力於在ebrian.js中實現ACL，我正在尋找一種根據某些功能的結果有條件地觸發路由的方法。 我應該使用execute還是route？

 function isRouteAuthorized(route, name) { // returns true or false depending on some conditions } Backbone.Router.extend({ routes: {"": "users", "resources": "resources",}, route: function (route, name, callback) { if (isRouteAuthorized(route, name)) { //follow to route // How to achieve this ?? } else { //go to error route // How to achieve this ?? } }, users: function () { //display users view }, resources: function () { //display resources view }, error: function () { //display error view } });

使用router.navigate()方法使用其他路由。 您需要將{trigger: true}作為選項傳遞給它，以便它也調用指定的路由器方法。

 Backbone.Router.extend({ routes: {"": "users", "resources": "resources",}, execute: function (callback, name, args) { if (condition) { //follow to route callback.apply(this, args); } else { //go to error route this.navigate('error', {trigger: true}); } return false; }, users: function () { //display users view }, resources: function () { //display resources view }, error: function () { //display error view } });
