使用javascript将查询参数传递给嵌入式iframe

function parseQueryParams(queryString) {
  var queryParams = {};
  var params = queryString.substr(1).split('&');
  
  for (var i = 0; i < params.length; i++) {
    var param = params[i].split('=');
    var key = decodeURIComponent(param[0]);
    var value = decodeURIComponent(param[1]);
    
    queryParams[key] = value;
  }
  
  return queryParams;
}

var queryParams = parseQueryParams(window.location.search);

var iframeUrl = 'https://example.com/iframe.html';

// 添加查询参数到URL中
for (var key in queryParams) {
  iframeUrl += (iframeUrl.indexOf('?') === -1 ? '?' : '&') + key + '=' + encodeURIComponent(queryParams[key]);
}

var iframe = document.createElement('iframe');
iframe.src = iframeUrl;

// 将iframe添加到页面中的某个元素中
document.getElementById('iframeContainer').appendChild(iframe);
