AngularJS:将新数据推送到 $scope.myList，顶部 [英] AngularJS: pushing new data to $scope.myList, top

问题描述

当我想操作 DOM 时，向 $scope.myList = [] 添加新内容的权利是什么?

What is the right to add new content to $scope.myList = [], when I want to manipulate the DOM?

我试过 $scope.myList.push(data);，它在末尾添加新数据，因此在 ng-repeater 内的 HTML 模板的末尾.我想要它在顶部.unshift-function 将重新排列数组并更新所有元素.

I've tried $scope.myList.push(data);, which adds the new data at the end, and therefore in the end of the HTML-template inside ng-repeater. I want it at the top. unshift-function will rearrange the array and update all elements.

New to angular.

也许问题应该是:我应该如何将新内容动态添加到模板顶部?

Maybe instead the question should be: How should I add new content dynamically into the top of my template?

推荐答案

每当您想添加到数组之前，您都需要重新排列整个数组.如果您可以指定data 的格式，我建议您添加一个entry_number 或id 作为data 并使用 angular filter 将新项目放置到顶部.

Whenever you want to prepend to an array, you will be rearranging the entire array. If you can dictate the format of the data, I suggest you add a entry_number or id as a field of the data and use angular filter to place the new items to the top.
