Google App Engine Apis [已关闭](Google App Engine Apis [closed])

我是Google App Engine的新手。 我正在使用python和django rest api框架构建一个Web应用程序。 我正在为我的数据库和存储使用云bigtable,云sql和云存储。 我想知道我是否必须使用Google App Engine Apis,还是可以在django中构建自己的数据来读取和写入数据库并从云存储中获取文件? 我想尝试降低成本,而不是锁定Google App Engine。


I am new to Google App Engine. I am building a web app using python and django rest api framework. I am using cloud bigtable, cloud sql and cloud storage for my databases and storage. I wanted to know if I have to use Google App Engine Apis or can I build my own in django to read and write data to the databases and get files from cloud storage? I want to try to keep costs low and not lock in to Google App Engine.

如果你想在提交之前看到复选框项的值,可以通过javascript或jquery完成。

您可以通过document.getElementsByName(“checkme”)[0]获取复选框项的值。

但是,除非您在同一页面上处理提交,否则在提交表单时仍然难以获得复选框值。

如果您在同一页面中处理表单提交,则可以使用上面的代码获取每个复选框的值,即使是那些未选中的复选框也是如此。


If you want to see the value of the checkboxes item before submitting it can be accomplish via javascript or jquery.

You can get the value of the checkboxes item by document.getElementsByName("checkme")[0].

But still you'll have difficulty in getting the checkboxes value upon submission of the form unless you're processing the submission on the same page.

If you process the form submission in the same page you can use the code above to get the value of each checkboxes even those not checked.
