基本用法

简单的步骤条。

import { Component } from '@angular/core';
@Component({
  selector: 'nz-demo-steps-simple',
  template: `
    <nz-steps>
      <nz-step nzTitle="Finished" nzDescription="This is a description."></nz-step>
      <nz-step nzTitle="In Progress" nzDescription="This is a description."></nz-step>
      <nz-step nzTitle="Waiting" nzDescription="This is a description."></nz-step>
    </nz-steps>
  `
})
export class NzDemoStepsSimpleComponent {}

迷你版

迷你版的步骤条，通过设置 <nz-steps nzSize="small"> 启用.

import { Component } from '@angular/core';
@Component({
  selector: 'nz-demo-steps-small-size',
  template: `
    <nz-steps [nzCurrent]="current" nzSize="small">
      <nz-step nzTitle="Finished"></nz-step>
      <nz-step nzTitle="In Progress"></nz-step>
      <nz-step nzTitle="Waiting"></nz-step>
    </nz-steps>
  `
})
export class NzDemoStepsSmallSizeComponent {
  current = 1;
}

起始序号

通过 nzStartIndex 来设置步骤条的起始序号. 请注意 nzCurrent 也应该有对应的偏移.

import { Component } from '@angular/core';
@Component({
  selector: 'nz-demo-steps-start-index',
  template: `
    <nz-steps [nzCurrent]="current" [nzStartIndex]="3" nzSize="small">
      <nz-step nzTitle="Finished"></nz-step>
      <nz-step nzTitle="In Progress"></nz-step>
      <nz-step nzTitle="Waiting"></nz-step>
    </nz-steps>
  `
})
export class NzDemoStepsStartIndexComponent {
  current = 3;
}

带图标的步骤条

通过设置 nz-step 的 nzIcon 属性，可以启用自定义图标。

import { Component } from '@angular/core';
@Component({
  selector: 'nz-demo-steps-icon',
  template: `
    <nz-steps>
      <nz-step nzTitle="Login" nzStatus="finish" nzIcon="user"></nz-step>
      <nz-step nzTitle="Verification" nzStatus="finish" nzIcon="solution"></nz-step>
      <nz-step nzTitle="Pay" nzStatus="process" nzIcon="loading"></nz-step>
      <nz-step nzTitle="Done" nzStatus="wait" [nzIcon]="iconTemplate"></nz-step>
      <ng-template #iconTemplate><i nz-icon nzType="smile"></i></ng-template>
    </nz-steps>
  `
})
export class NzDemoStepsIconComponent {}

步骤切换

通常配合内容及按钮使用，表示一个流程的处理进度。

import { Component } from '@angular/core';
@Component({
  selector: 'nz-demo-steps-step-next',
  template: `
    <nz-steps [nzCurrent]="current">
      <nz-step nzTitle="Finished"></nz-step>
      <nz-step nzTitle="In Progress"></nz-step>
      <nz-step nzTitle="Waiting"></nz-step>
    </nz-steps>
    <div class="steps-content">{{ index }}</div>
    <div class="steps-action">
      <button nz-button nzType="default" (click)="pre()" *ngIf="current > 0">
        <span>Previous</span>
      </button>
      <button nz-button nzType="default" (click)="next()" *ngIf="current < 2">
        <span>Next</span>
      </button>
      <button nz-button nzType="primary" (click)="done()" *ngIf="current === 2">
        <span>Done</span>
      </button>
    </div>
  `,
  styles: [
    `
      .steps-content {
        margin-top: 16px;
        border: 1px dashed #e9e9e9;

      }
      button {
        margin-right: 8px;
      }
    `
  ]
})
export class NzDemoStepsStepNextComponent {
  current = 0;
  index = 'First-content';
  pre(): void {
    this.current -= 1;
    this.changeContent();
  }
  next(): void {
    this.current += 1;
    this.changeContent();
  }
  done(): void {
    console.log('done');
  }
  changeContent(): void {
    switch (this.current) {
      case 0: {
        this.index = 'First-content';
        break;
      }
      case 1: {
        this.index = 'Second-content';
        break;
      }
      case 2: {
        this.index = 'third-content';
        break;
      }
      default: {
        this.index = 'error';
      }
    }
  }
  constructor() {}
}
