angular6开发steps步骤条组件

本文实例为大家分享了angular6开发steps步骤条组件的实现代码，供大家参考，具体内容如下：

1、先展示步骤条效果

2、使用angular命令快速创建组件

ng g c component/steps

创建的组件在component文件夹下面

打开steps.component.ts文件，可以看到selector的值是app-steps

import { Component, OnInit} from '@angular/core';

@Component({
selector: 'app-steps',
templateUrl: './steps.component.html',
styleUrls: ['./steps.component.css']
})
export class StepsComponent implements OnInit {
constructor() { }
ngOnInit() { }
}

3、代码

1）steps.component.html

<div class="steps">
<ul class="lineUl">
<li *ngFor="let item of stepsData; let i=index" [ngClass]="{'liWidth': i+1 == stepsData.length}">
<div class="stepsIcon">
<div class="radioSelect radioSelectDisabled" [ngClass]="{'radioSelectDisabled': i+1>active}"></div>
<div *ngIf="i+1 != stepsData.length" class="line" [ngClass]="{'lineDefaule': i+2>active}">
<span *ngIf="!!item.tips">{ {item.tips}}</span>
</div>
</div>
</li>
</ul>

<ul class="text">
<li *ngFor="let item of stepsData; let i=index">
<div class="title" *ngIf="!!item.title">{ {item.title}}</div>
<div class="description" *ngIf="!!item.description">{ {item.description}}</div>
</li>
</ul>
</div>

2）steps.component.ts

import { Component, OnInit, Input } from '@angular/core';
//引入Input
@Component({
selector: 'app-steps',
templateUrl: './steps.component.html',
styleUrls: ['./steps.component.css']
})
export class StepsComponent implements OnInit {

@Input() stepsData:any;
@Input() active:string;
constructor() { }

ngOnInit() {
console.log(!!!this.active)
if(!!!this.active){
this.active="1";
}
}

}

3）steps.component.css

.steps ul{
display: flex;
}

li{
width: 100%;
text-align: center;
}

.lineUl{
padding: 0px 10%;
margin-bottom: 5px;
}

.liWidth{
width: 20px;
}

.stepsIcon{
display: flex;
}

.radioSelect {
box-sizing: border-box;
display: inline-block;
border-radius: 100%;
border: 1px solid #26a2ff;
position: relative;
width: 20px;
height: 20px;
vertical-align: middle;
background-color: #26a2ff;
}

.radioSelect::after {
border: 2px solid transparent;
border-left: 0;
border-top: 0;
content: ' ';
top: 3px;
left: 6px;
position: absolute;
width: 4px;
height: 8px;
border-color: #fff;
-webkit-transform: rotate(45deg) scale(1);
transform: rotate(45deg) scale(1);
-webkit-transition: -webkit-transform 0.2s;
transition: -webkit-transform 0.2s;
transition: transform 0.2s;
transition: transform 0.2s, -webkit-transform 0.2s;
}

.radioSelectDisabled {
background-color: #d9d9d9;
border-color: #ccc;
}

.line{
display: block;
flex: 1;
height: 16px;
border-bottom: 1px solid#26a2ff;
margin-top: -5px;
font-size: 12px;
color: #26a2ff;
}

.lineDefaule{
border-bottom: 1px solid#d9d9d9;
}

.title{
font-size: 14px;
}

.description{
font-size: 12px;
}

4、在项目中引用创建的组件

<app-steps [stepsData]="stepsData" [active]='3'></app-steps>

public stepsData:any = [
{
title:'步骤1',
description:'描述文件'
},
{
title:'步骤2',
description:'描述文件'
},
{
title:'步骤3',
description:'描述文件',
tips:'待开奖'
},
{
title:'步骤4',
description:'描述文件'
}
];
