        var s = document.getElementsByTagName('script')[0];
        s.parentNode.insertBefore(gcse, s);
    })();

<gcse:searchresults-only></gcse:searchresults-only>
</div>

<div class="main">
	<br/><br/>
	<form action="" method="GET">
 <input class="q" name="q" placeholder="Search by Name or type URL" title="Search ..." value="" /> 
</form>

Answer 1

我不确定结果如何，但希望这项工作能够成功。

在搜索输入中添加了id="searchbox"。和这两行。

var urlParams = new URLSearchParams(window.location.search);
document.getElementById('searchbox').value = urlParams.get('q');

您现在的完整代码如下所示。

<div class="main">
    <br/><br/>
    <form action="" method="GET">
 <input class="q" name="q" id="searchbox" placeholder="Search by Name or type URL" title="Search ..." value="" /> 
</form>
</div>
<script>
    (function() {
        var cx = '004533415228465222070:r2ak9s12hwi';
        var gcse = document.createElement('script');
        gcse.type = 'text/javascript';
        gcse.async = true;
        gcse.src = (document.location.protocol == 'https:' ? 'https:' : 'http:') + '//www.google.com/cse/cse.js?cx=' + cx;
        var s = document.getElementsByTagName('script')[0];
        s.parentNode.insertBefore(gcse, s);
    })();
var urlParams = new URLSearchParams(window.location.search);
document.getElementById('searchbox').value = urlParams.get('q');
</script>
<gcse:searchresults-only></gcse:searchresults-only>
