intro.js的React包装器无法识别元素

Question

我正在使用intro.js的react包装器。我正在尝试将其集成到功能组件中。这些步骤工作正常，但intro.js无法正确识别这些步骤中提供的元素。我尝试过用document.getElementById()和document.querySelector()来定义元素，.Nothing似乎还行得通。还有别的办法吗？

import React,{useState} from 'react'

import { Steps, Hints } from "intro.js-react";

import "intro.js/introjs.css"

import "intro.js/themes/introjs-nassim.css";

const AppIntro = () =>{

const [stepsEnabled, setStepsEnabled] = useState(false)
const [initialStep, setInitialStep] = useState(0)
const [steps, setSteps] = useState([
    {
        intro:"Welcome to our application",
        position: 'top'
    },
    {
        element:document.getElementById('.card'),
        intro: 'This is the second step',
        position: 'left'
    },
    {
        element: document.querySelector('.tableRow'),
        intro:'This is the third step',
        position: 'top'
    }
])
 const onExit = () =>{
    setStepsEnabled(false);
  }
const startIntro=()=>{
    setStepsEnabled(true)
}
return(
    <div>
    <button onClick={()=>startIntro()}>Click me</button>
    <Steps
         enabled={stepsEnabled}
         steps={steps}
         initialStep={initialStep}
         onExit={onExit}
         options=
         {{
             tooltipClass: 'customTooltip',
             showProgress: true,
             showStepNumbers: true,
             showBullets: false,
             exitOnOverlayClick: false,
             doneLabel: "Done",
             nextLabel: "Next",
             hideNext: false,
         }}
     />
     </div>
)

}导出默认AppIntro

这是我的组件

你需要更换

    {
        element:document.getElementById('.card'),
        intro: 'This is the second step',
        position: 'left'
    },
    {
        element: document.querySelector('.tableRow'),
        intro:'This is the third step',
        position: 'top'
    }

使用

    {
        element: '.card',
        intro: 'This is the second step',
        position: 'left'
    },
    {
        element: '.tableRow',
        intro:'This is the third step',
        position: 'top'
    }

这将使步骤附加到具有.card和.tableRow类的元素。如果您希望使用ID来标识要附加到的元素，可以将'.card‘替换为'# card’，以便使用card的id附加到该元素。
