miniapp | 使用 Rax 语法（类 React）编写跨多端的小程序应用。 | Frontend Framework library

Dear StackOverflow users,

I made a module for both browser and WeChat mini program. That module is written in multiple TypeScript and is compiled to one minified file. In that module, I need to use DOM/BOM APIs such as document, 'window, 'navigator. On the browser, loading and using the compiled single-file have no problem.

But on the WeChat mini-program, there's no global object as on Node. Nor there's no document and window global objects as on browser. To fix this, I made two build commands for each environment.

• grunt build, standard TS compilation for browser
• grunt wx_build, standard TS compilation and append patch code for WeChat mini program

The patched js file looks like:

I have problems with the functionality of my code when I add persons from dropdow into the list or from the list back to the dropdown then alot of bugs occurs e.x the same person get added 2 times or when I delete one person then an otherone gets deleted instead, and I'm not sure where the bug/mistake is, maybe you can help me out.

I am building a very simple RESTFUL app to see how Node and Mongo work together.

A made a function to find a "Persona" document on a mongodb by Id, so here is the code:

I have the following little app that displays a grid of photos. When a photo is pressed/clicked, then a larger version opens up.

Technically, it works. However, it's very slow in my Android virtual device. I am also seeing these messages pop-up in the Android Studio logs.

I/Choreographer: Skipped 38 frames! The application may be doing too much work on its main thread.

So I must be doing something wrong.

Given the code below, is there a way to "fix" this?

Thanks!

I'm trying to create a basic iOS-app based on ReactNative using Electrode (Walmart - http://www.electrode.io/site/docs/introduction.html)

While I can get the app to work locally on my Mac, I'm struggling to understand how the whole Over-The-Air (OTA) update can/should work.

Here's what I've done so far

• created a mini-app using ern create-miniapp TestApp
• created a GIT-repository on BitBucket
• created a Cauldron using ern cauldron repo add TestApp [Bitbucket-url]
• added a nativeapp using ern cauldron add native app TestApp

But when I run the app using ern run-ios, it still seems to point towards my local machine (I can update the index-ios.js-file and it updates in the app). So what is lacking for getting the whole OTA-setup going where another programmer can updates the index-ios.js-file in the cloud/bitbucket (I'm guessing) and update the app on the fly?

I have a note taking program that allows me to switch between notes with a press of a button. This is convenient for me. I have a little safety built in where when I have active notes in the text box, pressed any key on my keyboard while inside that text box and then tried to select a different group of notes it will ask me if I want to change notes without saving.

This works well enough however I need to find a way where it only detects if changes are made to the notes rather than detecting a key press. The reason for this is I am unable to use a "CTRL-C" to copy sections of my notes without setting in motion the events that cause the pop up warning. I would like to be able to continue Jumping from one group of notes to another unless an edit has been made to the text inside the TextBox.

If you try to copy any text that you highlight with "CTRL-C" then you will see that trying to switch notes will also ask you if you are sure you want to switch. I am trying to avoid this and I figure there should be a way to check if the notes have had any changes rather than detecting keypress inside of the TextBox.

I have tried to use textvariable with track but tkinters text box does not appear to be able to use that option.

Below is simple example of how typing in the text box and then selecting to open a different set of notes will ask you if you want to continue.

I have a clock I place in my GUI programs. Currently I use .after() to keep the clock updated. I am not sure if this method is the best option and I was trying to find a different or better solutions.

Is the way I am currently dealing with my GUI Clock the best way? Or is there something else I can be doing?

Here is an example:
