程序代码：

<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>search</title>
    <script>
        function search() {
            var searchContent = document.getElementById("search_content").value;
            alert(searchContent);
        }
    </script>
</head>
<body>
    <input id="search_content" type="text" placeholder="输入你要搜索的内容" /><button onclick="search()">搜索</button>
