的indexOf（）需要找到一個字符串

所以我有一個輸入的元素，讓我做以下內數組定義的關鍵字：對角$範圍/陣列的indexOf（）需要找到一個字符串

過濾器 - 工程
在使用回車鍵時，它附加/推送到$ Scope/Array - Works
標識輸入和警報字符串中的關鍵字 - 不起作用 3.1如果我只鍵入關鍵字，例如「bguser」 3.2如果我輸入的關鍵字不多，例如「Simon Edwards bguser」
的關鍵字數組是當前定義的內聯

$scope.checkKeyword = function() { var elem = {name: $scope.addName.name}; if (['bguser', 'bgadmin'].indexOf(elem.name) >= 0) { alert(elem.name); } };

，但我想它注入可能的話從$ scope.keywordlist

$scope.keywordlist = [ 
     {name: 'bguser'}, 
     {name: 'bgadmin'}, 
     ];

我需要幫助得到這個（ 3）& 4）工作。我已在在Fiddle

下面你可以enuamrate關鍵字列表，並檢查當前關鍵字是你的輸入範圍內：

var elem = {name: $scope.addName.name}; 
    angular.forEach($scope.keywordlist, function(keyword) { 
    console.log(0); 
    if (elem.name.indexOf(keyword.name) > -1) 
     alert(elem.name); 
});

看到這個fiddle

工程就像一個魅力。謝謝。我似乎得到了一個雙重警報，但是，1.當鍵入關鍵字（我需要這個），2.當我按Enter/Return鍵（不需要這個）。這可能是由於ng-keyup，你知道如何告訴ng-keyup忽略輸入/返回鍵嗎？ – ssedwards

沒關係我已經設法解決這個問題:-)當我設置$ scope.addName.name =「」;在推完成之後，它停止了雙重警報。再次感謝。 – ssedwards
