ui-router $transitions 用法

1. //route redirection
$transitions.onStart({to: 'manage'}, function (trans) {
    var params = trans.params();
    return trans.router.stateService.target('manage.department', params);
});
$transitions.onStart({to: 'home'}, function (trans) {
    return trans.router.stateService.target('home.task');
});

2.//监听路由变化
$rootScope.$on('$locationChangeStart', function (event, toState, fromState) {
   // toState,fromState为URL
　　paramsSvc.tableEditGroupId = 'ALL';
});

3.执行条件：从一个路由离开时，判断路由不等于某个路由时：
$transitions.onSuccess({from: 'manage.database.data'}, function (trans) {
    if (trans.to().name != 'manage.database.data') {
        paramsSvc.columnCondition = [];
    }
});

4.页面切换执行
$transitions.onSuccess({}, function (trans) {
　　//获取路由名称
　　var currentRoute = transition.to().name;
　　var fromRoute = transition.from().name;
　　//获取路由参数
　　var currentRouteParams = transition.params('to');
　　var fromRouteParams = transition.params('from');
});
