清除 Angularjs state.go 参数 [英] Clear Angularjs state.go parameters

问题描述

我正在开发 angularjs 应用程序.它就像 CRUD 应用程序.以下是应用程序结构

I am working on angularjs app. Its like CRUD app. Below is the app structure

Home (List)        => "/#!/"
--- Details page   => "/#!/home/details/-KcXruMX3ia6rokeZjCJ"
----- Edit page    => "#!/home/edit/-KcXruMX3ia6rokeZjCJ"

编辑页面后，我将用户重定向到详细信息页面，成功消息如下.

After edit page I redirect user to details page with success message as below.

$scope.msg = {type : "success","msg" : "User Updated"};
$state.go('home.details', { id : $scope.id, msg : $scope.msg });

直到这一步它工作正常，问题是当我点击其他用户/项目并进入详细信息页面时，我仍然看到该消息.

Till this step it works fine, Problem is when I click on other user/item and come to details page I still see that message.

下面是我的详细信息控制器

Below is my details controller

myApp.controller("detailsCtrl",[
        "$scope",
        "$stateParams",
    function(
        $scope, 
        $stateParams, 
    ){
    // msg variables receives its values from previous actions 
    $scope.msg = $stateParams.msg;

}]);

如何通过使用一次来清除该消息?

How can I clear that message by using it once ?

推荐答案

如果你正在使用 ui-sref 那么你还可以提供状态参数，如 ui-sref="details({msg: ''})" 或者如果你想清除状态参数，当你转换到当前状态时，你可以提到 $state.go('.', {msg: undefined});

If you are using ui-sref then threre you can also provide the state params like ui-sref="details({msg: ''})" or if you want to clear the state params, when you are transitioning into current state you can mention $state.go('.', {msg: undefined} );
