在 ReactJS 中设计步进表单

步进器通过一系列逻辑和编号的步骤显示进度。它们也可用于导航。保存步骤后,步进器可能会显示瞬态反馈消息。

在本文中,我们将学习如何使用react 和 material-ui 创建一个垂直步进表单。我们将创建一个垂直步进器并向其添加一个表单容器。在步进形式的所有阶段,我们将添加不同的细节。就像您有不同的阶段来填写表格一样,完成所有步骤后,您将进入决赛。

创建 React 应用程序

第 1 步:使用以下命令创建反应应用程序。

npx create-react-app my-first-app

第 2 步:通过执行命令将目录更改为该文件夹:

cd my-first-app

第 3 步:安装必要的依赖项。转到目录'src'并在那里执行命令提示符并运行命令

npm install @material-ui/core/Stepper
npm install @material-ui/core/Step
npm install @material-ui/core/StepLabel

文件结构:它将如下所示。

第四步:在根组件中导入组件。

App.js
import GeekStepper from './StepperForm'
function App() {
  return (
    
           
  ); }    export default App;


StepperForm.jsx
import React from 'react';
import { makeStyles, Theme, createStyles } 
        from '@material-ui/core/styles';
import Stepper from '@material-ui/core/Stepper';
import Step from '@material-ui/core/Step';
import StepLabel from '@material-ui/core/StepLabel';
import StepContent from '@material-ui/core/StepContent';
import Button from '@material-ui/core/Button';
import Paper from '@material-ui/core/Paper';
import Typography from '@material-ui/core/Typography';
  
const useStyles = makeStyles((theme: Theme) =>
  createStyles({
    root: {
      width: '100%',
    },
    button: {
      marginTop: theme.spacing(1),
      marginRight: theme.spacing(1),
    },
    actionsContainer: {
      marginBottom: theme.spacing(2),
    },
    resetContainer: {
      padding: theme.spacing(3),
    },
      
  }),
);
  
function getSteps() {
  return ['Enter Personal Details', 
  'Enter Education Details', 
  'Enter Address'];
}
  
function getStepContent(step: number) {
  switch (step) {
    case 0:
      return (
        
                          

                          
      );     case 1:       return (         
                          

                          
      );     case 2:       return (         
                          

                          
      );     default:       return 'Unknown step';   } }    export default function GeekStepper() {   const classes = useStyles();   const [activeStep, setActiveStep] = React.useState(0);   const steps = getSteps();      const handleNext = () => {     setActiveStep((prevActiveStep) => prevActiveStep + 1);   };      const handleBack = () => {     setActiveStep((prevActiveStep) => prevActiveStep - 1);   };      const handleReset = () => {     setActiveStep(0);   };      return (

               {steps.map((label, index) => (                        {label}                            {getStepContent(index)}               
                
                                                      
              
            
          
        ))}       
      {activeStep === steps.length && (                    Form is submitted                           )}     
  ); }


第 5 步:在此文件中,我们将实施 Stepper Form 以提交用户的个人详细信息、教育详细信息和地址。 Stepper 是在 react 中使用 material-ui 创建的。我们在这个组件中导入了不同的 ui 类,如 Stepper、StepLabel 等。

表单是使用主动步骤和 ActiveStep 实现的。这些步骤用于显示处于活动状态的表单组件并返回。

StepperForm.jsx

import React from 'react';
import { makeStyles, Theme, createStyles } 
        from '@material-ui/core/styles';
import Stepper from '@material-ui/core/Stepper';
import Step from '@material-ui/core/Step';
import StepLabel from '@material-ui/core/StepLabel';
import StepContent from '@material-ui/core/StepContent';
import Button from '@material-ui/core/Button';
import Paper from '@material-ui/core/Paper';
import Typography from '@material-ui/core/Typography';
  
const useStyles = makeStyles((theme: Theme) =>
  createStyles({
    root: {
      width: '100%',
    },
    button: {
      marginTop: theme.spacing(1),
      marginRight: theme.spacing(1),
    },
    actionsContainer: {
      marginBottom: theme.spacing(2),
    },
    resetContainer: {
      padding: theme.spacing(3),
    },
      
  }),
);
  
function getSteps() {
  return ['Enter Personal Details', 
  'Enter Education Details', 
  'Enter Address'];
}
  
function getStepContent(step: number) {
  switch (step) {
    case 0:
      return (
        
                          

                          
      );     case 1:       return (         
                          

                          
      );     case 2:       return (         
                          

                          
      );     default:       return 'Unknown step';   } }    export default function GeekStepper() {   const classes = useStyles();   const [activeStep, setActiveStep] = React.useState(0);   const steps = getSteps();      const handleNext = () => {     setActiveStep((prevActiveStep) => prevActiveStep + 1);   };      const handleBack = () => {     setActiveStep((prevActiveStep) => prevActiveStep - 1);   };      const handleReset = () => {     setActiveStep(0);   };      return (

               {steps.map((label, index) => (                        {label}                            {getStepContent(index)}               
                
                                                      
              
            
          
        ))}       
      {activeStep === steps.length && (                    Form is submitted                           )}     
  ); }

运行应用程序的步骤:通过在 src 中执行以下命令来运行您的应用程序

npm start

输出:
