Question

在第1页上，我有一个带有onClick="window.location.href='Rendering.html?myVar1=3'"的按钮然后，我希望在第2页（myVar1）个函数中使用Rendering.html值。

在第2页中，我有：

var qs = new querystring();
var slideIndex = qs.get("myVar1")
showSlides(slideIndex);

但是，这似乎不起作用。

看看这个答案：How can I get query string values in JavaScript?

我发现功能有用：

import React, { Component } from 'react'
import { Route, Switch } from "react-router-dom";
import Amplify, { Auth  } from 'aws-amplify';
// import { AWS } from '@aws-amplify/core'; Following @Adam's comment. 
import { DynamoDB } from 'aws-sdk';

import PropTypes from 'prop-types'

import '../../stylesheets/Dashboard.css'

export default class Dynamo extends Component {

    constructor(props) {
        super(props)
        this.state = {}
    }

    componentDidMount() {
        Amplify.configure({
            Auth: {
                identityPoolId: identityPoolId,
                region: region,
                userPoolId: userPoolId,
                userPoolWebClientId: userPoolWebClientId,
            },
        });

        var context = this;
        Auth.currentCredentials().then(credentials => {
            // Constructor for the global config.
            console.log(credentials)
            var dynamodb = new DynamoDB({
                region: region,
                credentials: credentials
            }); 
...
