当我把NG-控制器DIV，而不是身体自动完成停止工作 [英] when I put ng-controller in div instead of body autocomplete stops working

问题描述

我有能力自动完成的文本框，点击后单击我按钮自动完成文本添加为​​表，这里是工作完全正常的联系，

I have a textbox with autocomplete capability and after clicking on click me button the text in autocomplete is added as in the table , here is the link that works perfectly fine,

 var app = angular.module('app', []);
app.factory('Service', function() {
    var typesHash = [ {
        id :1,
        name : 'lemon',
        price : 100,
        unit : 2.5
    }, {
        id : 2,
        name : 'meat',
        price : 200,
        unit : 3.3
    } ];

    var localId = 3;
    availableTags = [
                      "ActionScript",
                      "AppleScript",
                      "Asp",
                      "BASIC",
                      "C",
                      "C++",
                      "Clojure",
                      "COBOL",
                      "ColdFusion",
                      "Erlang",
                      "Fortran",
                      "Groovy",
                      "Haskell",
                      "Java",
                      "JavaScript",
                      "Lisp",
                      "Perl",
                      "PHP",
                      "Python",
                      "Ruby",
                      "Scala",
                      "Scheme"
                    ];
    var service = {
        addTable : addTable,
        getData : getData,
        complete:complete


    };
    return service;
    function complete($scope){
        $( "#txt" ).autocomplete({
          source: availableTags,
          messages: {
              noResults: '',
              results: function() {}
          }
        });
        $("#txt" ).on( "autocompleteselect", function( event, ui ) {
         $scope.tableTools.inputData=ui.item.value;
        } );
        } 
    function addTable(name,price) {
        typesHash.push({id:localId++, name:name, price:price,unit:1});
    }
    function getData() {
        return typesHash;
    }
});
app.controller('table', function(Service,$scope) {
    //get the return data from getData funtion in factory
    this.typesHash = Service.getData();
    //get the addtable function from factory 
    this.addTable = Service.addTable;
    this.complete=Service.complete($scope);
});

工作链接

但只要我把NG控制器=表作为tableTools的DIV，而不是身体，然后自动填入文本框的开始行动滑稽，它不能正常工作

but as soon as I put ng-controller="table as tableTools" in the div instead of body then autocompleting of text box start acting funny and it does not work properly

工作不链接

任何人都可以说明理由，并告诉我，我怎么能在这甚至把NG-控制器=表作为tableTools里面的div它的工作原理？

can anyone explain the reason and tell me how I can fix it in a way that even by putting ng-controller="table as tableTools" inside div it works?

更新：的

Update:

这里是错误：

未捕获类型错误：无法设置属性未定义inputData

这条线：

$scope.tableTools.inputData = ui.item.value;

（记住你点击建议的文本后，问题开始）

(remember the problem starts after you click on suggested text)

推荐答案

这个问题是隐藏在 angularjs 对象生命周期的missunderstanding。

The issue is hidden in missunderstanding of the angularjs object life-cycles.

这里最重要的是要知道的是：

The most important here to know is:

• 服务的（厂家/供应商...不同的创作，但最后一样）的有单身


• 控制器为实例每一查看即可。的（还有通过角应用续航时间一个控制器的多，多实例..）的

• services (factory/provider ... different creation, but at the end the same) are singletons
• controllers are instantiated per each view. (There are many, multi instances of one controller through the angular app life time..)

发生了什么？

有一个服务：

app.factory('Service', function() {
   ...

和有一个控制器，通过它的范围到该服务

and there is one controller passing its scope into that service

app.controller('table', function(Service,$scope) {
    ...
    this.complete=Service.complete($scope);

和在页面上，我们可以看到：

And on the page we can see:

// first usage of controller
// its first instance is created, $scope is passed
<div class="row commonRow" ng-controller="table as tableTools">

// second usage
// different instance is created... and it also passes the §scope
<tbody ng-controller="table as iterateTb">

但如上所述 - 服务只有一个。虽然第一个控制器通过它 $范围，第二个while以及..而导致问题确实了。

But as described above - service is only one. While first controller passes its $scope, the second does after while as well.. and that is causing the issue.

我们可以使用的服务控制器内。这就是棱角分明的设计原则。但是，我们不应该通过$范围...

We can use services inside of controllers. That is the design principle of angular. But we should not pass the $scope...
