我有一个数据库类别列表，如下所示：
[
"Travel",
"Apparel & Clothing",
"Footwear",
"Kids & Children",
"Grocery",
"Food & Beverage",
"Innerwear & Swimwear",
"Hotels",
"Bus Tickets",
"Mobiles & Tablets",
"Personalized Gifts",
"Jewellery & Coins",
"Car & Taxi Rental",
"Pharmacy",
"Watches",
"Bags & Wallets",
"Gifts & Flowers",
"Accessories",
"Games",
"Health",
"Beauty & Personal Care",
"Electronics"
]
我正在尝试从此类别列表创建路由，我不知道如何处理列表中某些类别的路由。
例如：
Apparel & Clothing
Bus Tickets
我如何处理＆＃39;＆amp;＆＃39;符号和角度为5的路由系统中的空间

我找到了类似于帮助器的解决方案，我们在Angular 5中有Pipes概念。
它帮助了我：
https://github.com/angular/angular-cli
我的自定义管道删除空格和特殊字符：
import { Pipe, PipeTransform } from '@angular/core';
@Pipe({
name: 'removeSpaceCharacters'
})
export class RemoveSpaceCharactersPipe implements PipeTransform {
transform(value: string): string {
let newValue = value.replace(/[^A-Z0-9]/ig, "");
return `${newValue}`;
}
}
