重点AngularJS输入杀死名单NG-重复过滤器 [英] AngularJS input with focus kills ng-repeat filter of list

问题描述

显然，这是由我作为新AngularJS引起的，但我不知道是什么问题。

Obviously this is caused by me being new to AngularJS, but I don't know what is the problem.

基本上，我有一个项目清单，并用于过滤坐落在一个蹦出侧抽屉列表中输入控制。结果
这完美的作品，直到我添加了一个指令，将焦点设置到输入控制，当它变得可见。然后重点工作，但过滤器停止工作。没有错误。删除焦点={{打开}}从标记，使过滤器的工作。

Basically, I have a list of items and an input control for filtering the list that is located in a pop out side drawer.
That works perfectly until I added a directive to set focus to that input control when it becomes visible. Then the focus works, but the filter stops working. No errors. Removing focus="{{open}}" from the markup makes the filter work.

对焦方式从这个计算器后采取：
如何设置焦点AngularJS？

The focus method was taken from this StackOverflow post: How to set focus in AngularJS?

下面是code ...

Here is the code...

/* impersonate.html */
<section class="impersonate">
    <div header></div>
    <ul>
        <li ng-repeat="item in items | filter:search">{{item.name}}</li>
    </ul>
    <div class="handle handle-right icon-search" tap="toggle()"></div>
    <div class="drawer drawer-right" 
         ng-class="{expanded: open, collapsed: !open}">
        Search<br />
        <input class="SearchBox" ng-model="search.name" 
               focus="{{open}}" type="text">
    </div>
</section>


// impersonateController.js
angular
    .module('sales')
    .controller(
        'ImpersonateController',
        [
            '$scope',
            function($scope) {
                $scope.open = false;
                $scope.toggle = function () {
                    $scope.open = !$scope.open;
                }
        }]
    );

// app.js
angular
    .module('myApp')
    .directive('focus', function($timeout) {
        return {
            scope: { trigger: '@focus' },
            link: function(scope, element) {
                scope.$watch('trigger', function(value) {
                    if(value === "true") { 
                        console.log('trigger',value);
                        $timeout(function() {
                            element[0].focus(); 
                        });
                    }
                });
            }
        };
    })

任何援助将大大AP preciated！

Any assistance would be greatly appreciated!

谢谢！

推荐答案

的焦点指令使用一个的隔离范围的

scope: { trigger: '@focus' },

所以，通过添加指令到输入 -tag， NG-模式=search.name不再指向 ImpersonateController ，但这一新的隔离范围。

So, by adding the directive to the input-tag, ng-model="search.name" no longer points to ImpersonateController but to this new isolated scope.

而不是尝试：

ng-model="$parent.search.name"

P.S：下一次，请尝试发布的可复制的code。我不得不做出了相当多的这一切是如何应接线的假设。

P.s.: next time, please try to post copyable code. I had to make quite a lot of assumptions of how all this should be wired up.
