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

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>

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\";
  }
 }

}

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\'
  }
 ];

//stepsData:步骤条参数
//active：设置当前激活步骤，默认为1
