问题 I have a huge collection of documents and I want to extract some statistics on it. It needs to be executed periodically each 15 minutes. Most of the stats are based on the document size, so I need to fetch the documents and calculate its size. The output of my stats is just a single line with some stats, regarding the size of the documents. (I am not fetching a whole collection, just a subset of it, so I cannot use the collection stats provided by mongodb) What I'd like is to make this

问题 I have a JSON Object { "widgetSettings":[{"maxDisplay": 6, "maxPerRow": 2}], "widgets": [ {"wigetID": 1, "show": false, "weight": 0, "widgetTitle": "Widget 1", "widgetColor": "defualt"}, {"wigetID": 2, "show": false, "weight": 0, "widgetTitle": "Widget 2", "widgetColor": "defualt"}, {"wigetID": 3, "show": false, "weight": 0, "widgetTitle": "Widget 3", "widgetColor": "defualt"}, {"wigetID": 4, "show": false, "weight": 0, "widgetTitle": "Widget 4", "widgetColor": "defualt"}, {"wigetID": 5,

问题 I have the server.js file on server side and the index.html on client side. I need to call a function from the server side through maybe a button or something on the index.html and get a feedbak on the index.html that the function was executed. In the future I would also like to pass over a variable to the server side from client side. I'm rather new to node.js. Hopefully someone can help me on this. 回答1: Node.js is no different than any other server side technology: it's not client side. If

问题 What is the easiest way to have a server-side session variable in Flask? Variable value: A simple string Not visible to the client (browser) Not persisted to a DB -- simply vanishes when the session is gone There is a built-in Flask session, but it sends the session data to the client: session["secret"] = "I can see you" The data is base64 encoded and sent in a cryptographically signed cookie, but it is still trivial to read on the client. In many frameworks, creating a server-side session

问题 I need to serve large datasets into a table over the web, through a Flask web-app. I'm trying to implement server-side pagination using the bootstrap-table extension and I'm having trouble getting it to work correctly. There's something about it that I'm not understanding. When the table renders, it correctly knows the number of rows in my table, and builds an appropriate page list. However, all the rows in the table get rendered on every single page. Also, the sorting and searching

问题 I'm trying to use datatables in server-side processing mode whereby data is loaded in batches , asynchronously. This is very useful for massive datasets. The documentation is clear enough (https://datatables.net/examples/data_sources/server_side.html), however, I'm struggling to work out how to implement it within Google Apps Script and its HTMLService. What I'm currently using (which is working) is datatables loading all the data in at once : $(document).ready(function() { google.script.run

问题 This is more out of curiosity and "for future reference" than anything, but how is Comet implemented on the database-side? I know most implementations use long-lived HTTP requests to "wait" until data is available, but how is this done on the server-side? How does the web server know when new data is available? Does it constantly poll the database? 回答1: What DB are you using? If it supports triggers , which many RDBMSs do in some shape or form, then you could have the trigger fire an event

问题 The validator controls that can be used for asp.net input validation... requiredfieldvalidator regularexpressionvalidator etc Do they perfrom validation on the client side AND server side or do I need to have seperate validation in my codebehind to validate on postback (ie to prevent POST injection)? 回答1: They perform both. The validation framework that has been implemented in asp.net was designed to work both client and server side. If you have used these validators, you do not need to write

问题 I'm creating an ASP.NET web application to schedule tasks on our server from a remote location using a .NET Wrapper for Scheduled Tasks. However, I'm stuck. The user needs to be able to browse the file system on the server to retrieve a "file to run" for the new task that the user's creating in this application. I need to get the filepath/filename and pass it into the .NET wrapper. I've tried using HTMLInputFile, but I haven't found a way to make that work for me. Any help is appreciated.
