一、知识点
dialog.showSaveDialog([browserWindow, ]options[, callback])
browserWindowBrowserWindow (可选)optionsObjecttitleStringdefaultPathStringfiltersArray
callbackFunction (可选)
成功使用这个方法的话，就返回一个可供用户选择的文件路径数组，失败返回 undefined.
filters 指定展示一个文件类型数组, 例子 dialog.showOpenDialog .
如果 callback 被调用, 将异步调用 API ，并且结果将用过 callback(filenames) 展示
二、示例
<!DOCTYPE html>
<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>Document</title>
</head>
<body>
<input type="button" id="btn" value="保存文件" />
<script>
const remote = require('@electron/remote');
const dialog = remote.dialog;
const fs =require('fs');
let btn = document.getElementById("btn");
btn.onclick = (e)=>{
dialog.showSaveDialog({
title:'保存文件',
defaultPath:'1.txt',
filters:[{name:'txt',extensions:['txt']}]
}).then(result=>{
console.log(result);
fs.writeFileSync(result.filePath,"123456");
}).catch(err=>{
});
}
</script>
</body>
</html>
