您需要如下所示的内容：

You need something like this:

<script>
function get_url_parameter(name) {
  return decodeURIComponent((new RegExp('[?|&]' + name + '=' + '([^&;]+?)(&|#|;|$)').exec(location.search)||[,""])[1].replace(/\+/g, '%20'))||null
}

document.addEventListener('DOMContentLoaded', doc_loaded, false);
function doc_loaded() {
    //var url = 'https://www.google.co.uk/?#q=' + get_url_parameter('q');
    var url = 'http://example.com/?#q=' + get_url_parameter('q');
    document.getElementById('iframe_id').src = url;
}
</script>
<iframe src="#" id="iframe_id" width="1000" height="500"></iframe>

但它不适用于Google，因为它发送了X-Frame-Options：SAMEORIGIN响应标题:(

but it will not work for Google because it's sending an "X-Frame-Options: SAMEORIGIN" response header :(
