Javascript Angularjs$stateChangeStart检查字符串是否在对象中

我的

app.run（）

中有以下代码：

在我的

$rootScope.$on（“$stateChangeStart”）

中，我想检查我的

toState.name

是否等于

window.audition.Config.somePage.routerName

的

控制台.log（）

输出以下内容：

"dashboard": {
    "routerName": "basicLayout.dashboard",
    "audience": [
        "faculty",
        "student",
        "employee"
    ]
},
"profile": {
    "routerName": "basicLayout.content",
    "audience": [
        "faculty",
        "student"
    ]
},
"academic_resources": {
    "routerName": "basicLayout.academicResources",
    "audience": [
        "student"
    ]
},
"university_services": {
    "routerName": "basicLayout.universityServices",
    "audience": [
        "student"
    ]
},
"support_center": {
    "routerName": "basicLayout.supportCenter",
    "audience": [
        "student",
        "faculty",
        "employee"
    ]
},
"progress_coach": {
    "routerName": "basicLayout.progressCoach",
    "audience": [
        "student"
    ]
}

我需要验证每次更改路由时，

toState.name

是否等于上述对象的任何

routerName

属性，是否有一种方法可以在if中执行此操作？

我实际上知道两种方法：

第一个，我见过许多人不喜欢它，但它包括检查你所在州的名称是否存在于你所在州。将其添加到

$stateChangeStart

事件函数中；您可以通过以下代码实现它。例如，如果要检查是否要进入仪表板

if (toState.name.indexOf('dashboard') > -1  ) {
            //do something. 
        }

实现它的第二种方法是使用原生$state，我认为它属于ui路由器，以防您使用该库或任何用于更改状态的库

$rootScope.$on('$stateChangeStart', function(event, toState) {...
  var stateName = $state.name; 
  console.log(stateName)
  console.log(toState)
 //Check your console because stateName and toState are formated as an 
  //object or smth like that.
 //You need to read and extract the first element of the array with a 
 //foreach. After that, you may use the real name from the state and compare
if (stateNameExtracted  === toStateExtracted){
     //do Something
    }
}

第二种方法需要更多的逻辑，但在我看来，它更干净

$rootScope.$on('$stateChangeStart', function(event, toState) {...
  var stateName = $state.name; 
  console.log(stateName)
  console.log(toState)
 //Check your console because stateName and toState are formated as an 
  //object or smth like that.
 //You need to read and extract the first element of the array with a 
 //foreach. After that, you may use the real name from the state and compare
if (stateNameExtracted  === toStateExtracted){
     //do Something
    }
}
