需求：看日志时，有的sql 非常的长，参数比较多，无法直接在sql 客户端工具执行，如果一个一个的把问号占位符替换为参数太麻烦，因此写个html 小工具，批量替换：
代码：
<!DOCTYPE html>
<html lang='en'>
<head>
<head><meta charset="UTF-8"><meta name="viewport" content="width=device-width, initial-scale=1.0"><title>sql转换工具</title><meta charset="utf-8"></head>

<body><h3>源SQL:</h3><textarea type = "textarea" id ="input1" style="width:1100px;height:110px; overflow:auto; border:1px solid green;" wrap ="soft" ></textarea><h3>参数:</h3><textarea type = "text" id ="input2" style="width:1100px;height:50px; overflow:auto; border:1px solid green;" wrap ="soft"></textarea><br/><br/><button type="button" onclick ="submit()">提交</button><button type="button" onclick ="clearContent()">清空</button><button type="button" onclick ="copyText()">复制结果</button><h3>转换结果:</h3><textarea type = "text" id ="input3" style="width:1100px;height:130px; overflow:auto; border:1px solid green;"wrap ="soft" readonly></textarea></body>
