每x个项目后有不同内容的ng-repeat列表

Question

I am trying to write a list that show 5 items then some additional content then the next 5 items in the list and keep doing this until the list has finished using ng-repeat.

eg

• 1
• 2
• 3
• 4
• 5
• extra content
• 6
• 7
• 8
• 9
• 10
• extra content
• 11
• 12
• 13
• 14
• 15

I have it working with the below example however I want the extra content to appear after every 5 items. Using my method below it would be very manual to implement this if I had for example 100 items in the list. Is there a way to inject a break after every x items in the list using ng-repeat or is there a better way to approach this?

see fiddle

<div ng-app="">
        <div ng-init="friends = [
        {name:'John', age:25, gender:'boy'},
        {name:'Jessie', age:30, gender:'girl'},
        {name:'Johanna', age:28, gender:'girl'},
        {name:'Joy', age:15, gender:'girl'},
        {name:'Mary', age:28, gender:'girl'},
        {name:'Peter', age:95, gender:'boy'},
        {name:'Sebastian', age:50, gender:'boy'},
        {name:'Erika', age:27, gender:'girl'},
        {name:'Patrick', age:40, gender:'boy'},
        {name:'Samantha', age:60, gender:'girl'}
      ]">
        <ul class="example-animate-container">
          <li ng-repeat="friend in friends | limitTo: 5">
            [{{$index}}] {{friend.name}} is {{friend.age}} years old.
          </li>
            <li>extra content</li>
          <li ng-repeat="friend in friends | limitTo: 10" ng-if="$index > 5">
            [{{$index}}] {{friend.name}} is {{friend.age}} years old.
          </li>        
        </ul>
      </div>
    </div>

Answer 1

As others have pointed out, ng-repeat-start/end should solve your problem, eg:

<li data-ng-repeat-start="friend in friends">
  [{{$index + 1}}] {{friend.name}} is {{friend.age}} years old.
</li>

<li data-ng-repeat-end data-ng-if="$middle && 0 === ($index + 1) % 5">
  extra content
</li>

 <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.3.2/angular.min.js"></script> <div data-ng-app ng-init="friends = [ {name:'John', age:25, gender:'boy'}, {name:'Jessie', age:30, gender:'girl'}, {name:'Johanna', age:28, gender:'girl'}, {name:'Joy', age:15, gender:'girl'}, {name:'Mary', age:28, gender:'girl'}, {name:'Peter', age:95, gender:'boy'}, {name:'Sebastian', age:50, gender:'boy'}, {name:'Erika', age:27, gender:'girl'}, {name:'Patrick', age:40, gender:'boy'}, {name:'Samantha', age:60, gender:'girl'} ]"> <ul class="example-animate-container"> <li data-ng-repeat-start="friend in friends"> [{{$index + 1}}] {{friend.name}} is {{friend.age}} years old. </li> <li data-ng-repeat-end data-ng-if="$middle && 0 === ($index + 1) % 5"> extra content </li> </ul> </div>

This sounds like a job for ng-repeat-start.

<div ng-app="">
    <div ng-init="friends = [
    {name:'John', age:25, gender:'boy'},
    {name:'Jessie', age:30, gender:'girl'},
    {name:'Johanna', age:28, gender:'girl'},
    {name:'Joy', age:15, gender:'girl'},
    {name:'Mary', age:28, gender:'girl'},
    {name:'Peter', age:95, gender:'boy'},
    {name:'Sebastian', age:50, gender:'boy'},
    {name:'Erika', age:27, gender:'girl'},
    {name:'Patrick', age:40, gender:'boy'},
    {name:'Samantha', age:60, gender:'girl'}
    ]">
        <ul class="example-animate-container">
            <li ng-repeat-start="friend in friends">
                [{{$index}}] {{friend.name}} is {{friend.age}} years old.
            </li>
            <li ng-if="(($index+1) % 5) == 0">extra content</li>
            <li ng-repeat-end ng-hide>
                <!-- Just an element to end the loop -->
            </li>
        </ul>
    </div>
</div>
