js 获取路径路径中参数的值

获取路径中参数的值, 并转换为json对象

使用正则表达式

function getParamsFromURL(url) {
  const regex = /[?&]([^=#]+)=([^&#]*)/g;
  const params = {};
  let match;
  while (match = regex.exec(url)) {
    params[decodeURIComponent(match[1])] = decodeURIComponent(match[2]);
  }
  return params;
}
 
const url = 'http://example.com?param1=value1&param2=value2';
const params = getParamsFromURL(url);
console.log(params); // 输出：{ param1: 'value1', param2: 'value2' }

使用URLSearchParams对象

function getParamsFromURL(url) {
  const searchParams = new URLSearchParams(url.split('?')[1]);
  const params = {};
  for (let param of searchParams) {
    params[param[0]] = param[1];
  }
  return params;
}
 
const url = 'http://example.com?param1=value1&param2=value2';
const params = getParamsFromURL(url);
console.log(params); // 输出：{ param1: 'value1', param2: 'value2' }
