ng-repeat 在两个数组上 [英] ng-repeat on two arrays

问题描述

我想对由两个数组组成的数组执行 ng-repeat，如下所示:

[标题:[]，链接:[]]

我的数组(标题和链接)具有相同的长度最后，我想在我的 ng-repeat 中打印的内容是这样的:

{{ array.title }}{{ 数组链接}}

例如，在 C 程序中，我必须这样做:

int i;我 = 0;而(标题[i]){printf("%s - %s", titles[i], links[i]);我++;}

解决方案

不清楚您是如何获得数据的 — [titles: [], links: []] 没有意义.

理想情况下，您将数据排列为如下所示的对象数组:

var array = [{title: "foo", link: "bar"}, {title...etc]

然后你可以使用:

{{obj.title}}, {{obj.link}}

如果您知道标题和链接的大小总是相同的，您可以这样做，但它不是很漂亮，而且可能有点脆弱:

{{title}}, {{links[$index]}}

I want to do a ng-repeat on an array which is composed of two arrays, like this :

[titles: [], links: []]

My arrays (titles and links) have the same length What i want to print in my ng-repeat, finally, is anything like that :

{{ array.title }}
{{ array.link }}

For example, in a C program i have to do that :

int i;

i = 0;
while (titles[i])
{
    printf("%s - %s", titles[i], links[i]);
    i++;
}

解决方案

It's not clear how you have your data — [titles: [], links: []] isn't meaningful.

Ideally you would arrange your data as an array of objects that looks like:

var array = [{title: "foo", link: "bar"}, {title…etc]

Then you could just use:

<div ng-repeat="obj in array">
   {{obj.title}},  {{obj.link}}

If you know that titles and links will always be the same size you can do this, but it's not very pretty and might be a little fragile:

<div ng-repeat="title in titles">
   {{title}}, {{links[$index]}}
</div>
