我创建了一个像
这样的json文件{" tests":{" CHE":{" Failover":[" Standalone Box Restart" ] "吸烟":["所有域名都被发布","没有FID复制"," PE和 RIC Mangling","实时更新 - FTN","只有一条响应消息 每个成分"," LIVE-STANDBY-LIVE Switch" ]},"查询":{ "查询":["获取区域服务" ]}}}
如何像树一样在HTML上显示真的快点。谢谢 像那样: enter image description here

你可以这样试试。
首先,您需要使用ng generate pipe testPipe
创建管道(这也将导入app.module.ts
文件中的依赖项),以便将对象转换为数组以循环遍历元素。
<强>测试pipe.pipe.ts 强>
import { Pipe, PipeTransform } from '@angular/core';
@Pipe({
name: 'keys'
})
export class TestPipePipe implements PipeTransform {
transform(value, args:string[]) : any {
let keys = [];
for (let key in value) {
keys.push({key: key, value: value[key]});
}
return keys;
}
}
在模板文件中放置下面提到的代码。
<div *ngFor="let item of data | keys">
<ul>
<li>
{{item.key}}
<ul *ngFor="let inItem of item.value | keys">
<li>
<input type="checkbox" name="">{{inItem.key}}
<ul *ngFor="let ininItem of inItem.value | keys">
<li>
<input type="checkbox" name="">{{ininItem.key}}
<ul *ngFor="let inininItem of ininItem.value | keys">
<li>
<input type="checkbox" name="">{{inininItem.value}}
</li>
</ul>
</li>
</ul>
</li>
</ul>
</li>
</ul>
</div>
您可以在组件文件中找到。
data = { "tests": { "CHE": { "Failover": [ "Standalone Box Restart" ], "Smoke": [ "All Domains Are Published", "No FID Duplication", "PE and RIC Mangling", "Real Time Updates - FTN", "Only One Response Message Per Constituent", "LIVE-STANDBY-LIVE Switch" ] }, "Queries": { "Queries": [ "Get Services For Region" ] } } }
