angularjsで関数を動的に作成する必要があります

Question

anglejsで新しい関数を作成する必要があるので、以下のようにしました。私はangular tree controlのいくつかの要素を無効にする必要があります。

$scope.filterTreeOption = { 
    dirSelectable: false, 
    multiSelection: true, 
    injectClasses: { 
     "li": "injectedTreeLi" 
    } 
} 

$scope.isFatalDisabled = false; $scope.isErrorDisabled = false; $scope.isWarnDisabled = false; $scope.isInfoDisabled = false; $scope.isDebugDisabled = false; $scope.isTomcatDisabled = false; $scope.isAgentDisabled = false; $scope.isSessionDisabled = false; $scope.isActivityDisabled = false; 

// Another function here which changes above boolean property to true if needed. 

var func = function(node) { 
    var tmp = (node.label.indexOf("Fatal") !== 0 && $scope.isFatalDisabled) && 
    (node.label.indexOf("Error") !== 0 && $scope.isErrorDisabled) && 
    (node.label.indexOf("Warn") !== 0 && $scope.isWarnDisabled) && 
    (node.label.indexOf("Info") !== 0 && $scope.isInfoDisabled) && 
    (node.label.indexOf("Debug") !== 0 && $scope.isDebugDisabled) && 

    (node.label.indexOf("Tomcat") !== 0 && $scope.isTomcatDisabled) && 
    (node.label.indexOf("Agent") !== 0 && $scope.isAgentDisabled) && 
    (node.label.indexOf("Session") !== 0 && $scope.isSessionDisabled) && 
    (node.label.indexOf("Activity") !== 0 && $scope.isActivityDisabled); 
    return tmp; 
} 

//and then I am trying to assign it to an already existing javascript object 

$scope.filterTreeOption.isSelectable = func; 

しかし、これは有効ではありません。これは正しい方法ですか、何か不足しています。助けてください。

あなたがindexOfのためと照合する必要がある値が文字列の最初のインデックスである、0ではありませんが、-1

$scope.filterTreeOption = { 
    dirSelectable: false, 
    multiSelection: true, 
    injectClasses: { 
     "li": "injectedTreeLi" 
    } 
} 

$scope.isFatalDisabled = false; $scope.isErrorDisabled = false; $scope.isWarnDisabled = false; $scope.isInfoDisabled = false; $scope.isDebugDisabled = false; $scope.isTomcatDisabled = false; $scope.isAgentDisabled = false; $scope.isSessionDisabled = false; $scope.isActivityDisabled = false; 

// Another function here which changes above boolean property to true if needed. 

var func = function(node) { 
    var tmp = (node.label.indexOf("Fatal") !== -1 && $scope.isFatalDisabled) && 
    (node.label.indexOf("Error") !== -1 && $scope.isErrorDisabled) && 
    (node.label.indexOf("Warn") !== -1 && $scope.isWarnDisabled) && 
    (node.label.indexOf("Info") !== -1 && $scope.isInfoDisabled) && 
    (node.label.indexOf("Debug") !== -1 && $scope.isDebugDisabled) && 

    (node.label.indexOf("Tomcat") !== -1 && $scope.isTomcatDisabled) && 
    (node.label.indexOf("Agent") !== -1 && $scope.isAgentDisabled) && 
    (node.label.indexOf("Session") !== -1 && $scope.isSessionDisabled) && 
    (node.label.indexOf("Activity") !== -1 && $scope.isActivityDisabled); 
    return tmp; 
} 

//and then I am trying to assign it to an already existing javascript object 

$scope.filterTreeOption.isSelectable = func;
