HTML 的 successHandler 函数中未显示来自服务器端函数的 GAS 数据
GAS Data from server side function not seen in successHandler function in HTML
我有一个 sheet 绑定的 Apps 脚本。我在日志中看到了我的服务器端代码 (listCourses)，并且找到了大量数据，最后一条语句是 return 数据，但客户端 withSuccessHandler 代码 (afterServerRepl(e)) 中的 JSON.stringify 看到空值？
以下代码来自 Alan Wells 的回答。我将其命名为“tinyTestHtml.html”。
<!DOCTYPE html>
<html>
<head>
<!-- tinyTestHtml.html -->
<meta http-equiv="content-type" content="text/html; charset=utf-8" />
<title>Choose a class</title>
<base target="_top">
<?!= HtmlService.createHtmlOutputFromFile('cssStyle').getContent(); ?>
</head>
<body>
This is the body
<script>
window.onload = function() {
console.log('hah! it ran. ');
google.script.run
.withSuccessHandler(afterServerRepl)
.listCourses();
};
function afterServerRepl(e) {
console.log('Server reply was successful!');
console.log(JSON.stringify(e) );
};
// window.afterServerRepl = function(e) {
// console.log('Server reply was successful!');
// console.log(JSON.stringify(e) );
// };
</script>
</body>
</html>
此 HTML 是从绑定到跨页的自定义菜单中显示的 sheet。以下是 fakeListCourses，因为只有在 Google 教室中有课程时才会得到输出。真正的代码包含在底部。您可以看到结果与名称和 ID 的二维数组相同。
function listCourses() {
console.log('Begin listCourses');
let unsrtCrsList = [

这是创建侧边栏的函数，它是一个模板，确实使用了 EVALUATE。

console.log('Begin showTinyTestHtml');
const ui = SpreadsheetApp.getUi();

我根据实际 listClasses 函数的 JSON.stringify 构建了假列表 类。我比较了排序代码和原始代码的输出，除了排序顺序之外看不出有什么不同。但是，当我在以下两个版本的 getFiles 之间切换时，带有排序的版本在 successHandler 中显示为 null。
这是任何人都可以 运行 的代码（不需要 类）。使用 inMimeType = 'EVERYTHING' 得到与原来相同的结果。新代码对文件进行排序。原代码没有。原始代码和新代码找到相同数量的文件，但新代码数据对进程开始的 HTML 中的 successHandler 不可见。

console.log(JSON.stringify(e) );
var data = {};

如果我按如下方式使用您的代码部署网络应用程序：
function doGet() {
console.log('Begin showTinyTestHtml');
/**
* Opens a sidebar to allow person to a single class
*/
let template = HtmlService
.createTemplateFromFile('tinyTestHtml');
let htmlOutput = template.evaluate()
.setTitle('Choose a Class')
.setWidth(400);
return htmlOutput;
}
当我访问 Web 应用程序时 URL 我阅读了控制台并且有 JSON 字符串，如下图所示：
更新：
如果我“按原样”使用您的脚本和 运行 编辑器中的函数 showTinyTestHtml，我也会得到预期的结果。
