【问题描述】:
我一直在按照 ember 快速入门指南创建一个显示一些数据 (https://guides.emberjs.com/v2.13.0/getting-started/quick-start/) 的应用程序,但我想显示来自以下 json 的产品,而不是只显示带有科学家姓名的 javascript 数组。
我已经将json文件放到了public文件夹中。
看起来像:
{
"products": [
{
"_id": "58ff60ffcd082f040072305a",
"slug": "apple-tree-printed-linen-butterfly-bow-tie",
"name": "Apple Tree Printed Linen Butterfly Bow Tie ",
"description": "This fun 40 Colori Apple Tree Printed Linen Butterfly Bow Tie features a design of various apple trees built from tiny polka dots. The back of this bow tie features a polka dot print in complementing colours which when the bow tie is tied will pop out from behind making for a subtle yet unique detail. The playful design, stand out natural linen texture, and colourful combinations make this bow tie a perfect accessory for any outfit!\n",
"standard_manufacturer": "58cbafc55491430300c422ff",
"details": "Size: Untied (self-tie) bow tie with an easily adjustable neck strap from 13-3/4'' to 19'' (35 to 48 cm)\nHeight: 6 cm\nMaterial: Printed 100% linen\nCare: Dry clean\nMade in Italy",
"sizes": [
{
"value": "Violet",
"size": "57722c80c8595b0300a11e61",
"_id": "58ff60ffcd082f0400723070",
"marked_as_oos_at": null,
"quantity": -1,
"stock": true,
"id": "58ff60ffcd082f0400723070"
},
等等。
我的显示列表的路由模型代码如下
import Ember from 'ember';
export default Ember.Route.extend({
model() {
//return ['Marie Curie', 'Mae Jemison', 'Albert Hofmann'];
return Ember.$.getJSON("/products.json");
}
});
我完全按照教程操作,除了
return Ember.$.getJSON("/products.json");
scientists.js 中的行。我的数据没有显示,我在 ember 检查器中遇到的错误是
compiled.js:2 Uncaught TypeError: Failed to execute 'getComputedStyle' on 'Window': parameter 1 is not of type 'Element'.
at E (compiled.js:2)
at Object.u (compiled.js:25)
at compiled.js:25
E @ compiled.js:2
u @ compiled.js:25
(anonymous) @ compiled.js:25
我对 ember 很陌生,对 js 也很陌生。任何帮助表示赞赏!谢谢!
