js 取url参数

// 假设当前URL是 "https://example.com/page?param1=value1&param2=value2"

// 获取查询字符串并创建URLSearchParams对象
const params = new URLSearchParams(window.location.search);

// 使用get方法获取特定参数的值
const param1 = params.get('param1'); // "value1"
const param2 = params.get('param2'); // "value2"

console.log(param1, param2);

// 假设当前URL是 "https://example.com/page?param1=value1&param2=value2"

// 获取查询字符串
const queryString = window.location.search.substring(1); // 去掉问号

// 使用正则表达式匹配参数
const params = queryString.match(/([^&=]+)=([^&]*)/g);

// 将匹配结果转换为对象
const paramObject = {};
params.forEach(param => {
    const [key, value] = param.split('=');
    paramObject[decodeURIComponent(key)] = decodeURIComponent(value);
});

console.log(paramObject.param1); // "value1"
console.log(paramObject.param2); // "value2"
