AngularJS NG-重复使用自定义元素在表内被渲染诡异 [英] AngularJS ng-repeat with custom element inside a table is rendering strangely

问题描述

我想重新使用在多个地方我的HTML视图的一部分。我想重新使用的部分是一个HTML表格表格单元格。问题是，一个NG重复里面我的自定义指令是做有趣的事情。我已复制的的jsfiddle 的问题。有在的jsfiddle两个HTML表。第一是纳克重复写在视图中的表格单元，第二个是从一个指令，我的元件来的表格单元。 Chrome的开发工具报告所呈现的HTML看起来像这样。需要注意的是自定义元素仅出现一次，是表外。

I'm trying to re-use a portion of my HTML view in multiple places. The portion I want to re-use is table cells in an HTML table. The problem is that my custom directive inside a ng-repeat is doing funny things. I have reproduced the problem on jsFiddle. There are two HTML tables in the jsFiddle. The first is ng-repeat with the table cells written in the view and the second is the table cells coming from a directive, my-element. Chrome dev tools report that the rendered HTML looks like this. Note that the custom element appears only once and is outside the table.

渲染HTML

<div ng-controller="MyCtrl" class="ng-scope">
    table1
    <table class="table table-hover">
      <tbody><!-- ngRepeat: p in people -->
          <tr ng-repeat="p in people" class="ng-scope">
            <td class="ng-binding">Name: Mike</td>
            <td class="ng-binding">Age: 20</td>
          </tr>
          <tr ng-repeat="p in people" class="ng-scope">
            <td class="ng-binding">Name: Peter S</td>
            <td class="ng-binding">Age: 22</td>
          </tr>
      </tbody>
    </table>
    <br>table2
    <my-element class="ng-binding">Name: Age: </my-element>
    <table class="table table-hover">
      <tbody>
        <!-- ngRepeat: p in people -->
        <tr ng-repeat="p in people" class="ng-scope">
        </tr>
        <tr ng-repeat="p in people" class="ng-scope">    
        </tr>
      </tbody>
    </table>
</div>

HTML源

<div ng-controller="MyCtrl">
    table1
    <table class="table table-hover">
        <tr ng-repeat="p in people">
            <td>Name: {{ p.name }}</td>
            <td>Age: {{ p.age }}</td>
        </tr>
    </table>
    <br/>table2
    <table class="table table-hover">
        <tr ng-repeat="p in people">
            <my-element></my-element>
        </tr>
    </table>
</div>

来源JS

var app = angular.module('myApp', []);

app.directive('myElement', function () {
    return {
        restrict: 'E',
        template: '<td>Name: {{ p.name }}</td><td>Age: {{ p.age }}</td>'
    }
});

function MyCtrl($scope) {
    $scope.people = [{
        name: 'Mike',
        age: 20
    }, {
        name: 'Peter S',
        age: 22
    }];
}

请注意，是的jsfiddle一个简单的例子和​​常识将导致刚刚没有使用的指令在所有。然而，我的目标code的，我想重新使用一个更大的模板。我一直在使用NG-包括以及尝试，但结果是相似的。

Please note the jsFiddle is a trivial example and common sense would lead to just not using directives at all. However, my target code has a much larger template that I want to re-use. I've tried using "ng-include" as well but the result is similar.

推荐答案

＆LT; TD＆GT; 众所周知，在这样的指令奇怪的行为。相反，使用指令父＆LT; TR＆GT; 。了解更多关于这里这个问题：<一href=\"https://github.com/angular/angular.js/issues/1459\">https://github.com/angular/angular.js/issues/1459

<td> is known to behave strangely in directives like this. Instead, use a directive on the parent <tr>. Read more about this issue here: https://github.com/angular/angular.js/issues/1459

<table>
    <tr ng-repeat="p in people" my-element></tr>
</table>

下面是你如何能进一步提升您的指令，以便它更可重用。

Here is how you can further improve your directive so that it is more re-usable.

app.directive('myElement', function () {
  return {
    scope: {
      item: '=myElement'
    },
    restrict: 'EA',
    template: '<td>Name: {{item.name}}</td><td>Age: {{item.age}}</td>'
    };
});

和传递项的值像这样：

  <table>
    <tr ng-repeat="person in people" my-element="person"></tr>
  </table>
