ng-重复完成事件 [英] ng-repeat finish event

问题描述

我想用表格调用一些针对 div 的 jQuery 函数.该表填充了 ng-repeat.

当我调用它时

$(document).ready()

我没有结果.

还有

$scope.$on('$viewContentLoaded', myFunc);

没有帮助.

ng-repeat 填充完成后有什么方法可以立即执行函数吗?我已经阅读了关于使用自定义 directive 的建议，但我不知道如何将它与 ng-repeat 和我的 div 一起使用...

解决方案

确实，您应该使用指令，并且没有与 ng-Repeat 循环结束相关的事件(因为每个元素都是单独构造的，并且具有自己的事件).但是 a) 使用指令可能就是你所需要的，b) 有一些 ng-Repeat 特定属性可以用来制作on ngRepeat 完成"事件.

具体来说，如果您只想为整个表格设置样式/添加事件，您可以在包含所有 ngRepeat 元素的指令中使用.另一方面，如果你想具体地处理每个元素，你可以在 ngRepeat 中使用一个指令，它会在每个元素被创建后作用.

然后，您可以使用 $index、$first、$middle 和 $last 属性用于触发事件.所以对于这个 HTML:

<div ng-repeat="事物中的事物" my-repeat-directive>东西{{东西}}

你可以像这样使用指令:

angular.module('myApp', []).directive('myRepeatDirective', function() {返回函数(范围，元素，属性){angular.element(element).css('color','blue');如果(范围.$last){window.alert("我是最后一个！");}};}).directive('myMainDirective', function() {返回函数(范围，元素，属性){angular.element(element).css('border','5px 纯红色');};});

在这个 Plunker 中查看它的实际效果.希望能帮到你！

I want to call some jQuery function targeting div with table. That table is populated with ng-repeat.

When I call it on

$(document).ready()

I have no result.

Also

$scope.$on('$viewContentLoaded', myFunc);

doesn't help.

Is there any way to execute function right after ng-repeat population completes? I've read an advice about using custom directive, but I have no clue how to use it with ng-repeat and my div...

解决方案

Indeed, you should use directives, and there is no event tied to the end of a ng-Repeat loop (as each element is constructed individually, and has it's own event). But a) using directives might be all you need and b) there are a few ng-Repeat specific properties you can use to make your "on ngRepeat finished" event.

Specifically, if all you want is to style/add events to the whole of the table, you can do so using in a directive that encompasses all the ngRepeat elements. On the other hand, if you want to address each element specifically, you can use a directive within the ngRepeat, and it will act on each element, after it is created.

Then, there are the $index, $first, $middle and $last properties you can use to trigger events. So for this HTML:

<div ng-controller="Ctrl" my-main-directive>
  <div ng-repeat="thing in things" my-repeat-directive>
    thing {{thing}}
  </div>
</div>

You can use directives like so:

angular.module('myApp', [])
.directive('myRepeatDirective', function() {
  return function(scope, element, attrs) {
    angular.element(element).css('color','blue');
    if (scope.$last){
      window.alert("im the last!");
    }
  };
})
.directive('myMainDirective', function() {
  return function(scope, element, attrs) {
    angular.element(element).css('border','5px solid red');
  };
});

See it in action in this Plunker. Hope it helps!
