JavaScript -获取编码的URI的url参数

function getURLParameters(url) {
  var params = {};
  var paramArray = url.split('?')[1].split('&');
  
  for (var i = 0; i < paramArray.length; i++) {
    var param = paramArray[i].split('=');
    var paramName = decodeURIComponent(param[0]);
    var paramValue = decodeURIComponent(param[1]);
    params[paramName] = paramValue;
  }
  
  return params;
}

var url = "https://example.com/?name=%E5%BC%A0%E4%B8%89&age=20";
var params = getURLParameters(url);

console.log(params.name); // 输出：张三
console.log(params.age); // 输出：20
