如何获取URL参数并在'iframe‘中使用？

function getURLParams() {
  var params = {};
  var queryString = window.location.search.slice(1);
  var paramPairs = queryString.split('&');
  
  for (var i = 0; i < paramPairs.length; i++) {
    var pair = paramPairs[i].split('=');
    var key = decodeURIComponent(pair[0]);
    var value = decodeURIComponent(pair[1]);
    
    params[key] = value;
  }
  
  return params;
}

var urlParams = getURLParams();

var iframe = document.getElementById('myIframe');
var iframeSrc = iframe.src;

// 将URL参数添加到iframe的src属性中
iframe.src = iframeSrc + '?param1=' + urlParams.param1 + '&param2=' + urlParams.param2;
