QUESTION
Consider the following example:
https://codesandbox.io/s/vdebounce-input-override-ej4nz
It's a simplified (and mostly mocked) version of a larger app, using Observables to get filtered results from multiple APIs, based on user inputs. I need the inputs debounced.
In the app the debounce value is larger, so the issue's less noticeable, but I've lowered it in the example to make the issue easier to spot. I also tried to mock the randomness of the server response times.
The issue is that whenever I get a response back, if I'm typing in the input I lose a few characters, depending on how fast I type.
If I remove the v-debounce
directive (or the .lazy
modifier), the issue is gone, but there's no debounce.
I've also raised it on the v-debounce repo.
I know I could dump .v-debounce
altogether and use lodash's debounce inside the watch, but I was hoping I don't have to do that (since v-debounce
is supposed to be catered for Vue, right!?). I've tried to keep things as "Vue" as possible so far
Important edit: (after it was answered) It appears there are two packages defining a v-debounce
directive. The good one is here: npm, github.
ANSWER
Answered 2019-May-21 at 09:19The problem you're having is the interplay between markup rendering and event debouncing (which may be a problem of v-debounce or an intended behaviour opinions may vary):
- You are debouncing a triggering of the change event on the input element
- That debounced event triggers with the input's value at the time of call (that is, it has no memory of call data in the debounced call)
- Separately (at each actual call of the debounce) you have an asynchronous operation (mock server search) change the state of the component, and trigger a component re-render
- This re-render checks the whole of the component DOM, and "corrects" the input value it sees as wrong
- When a debounced change event triggers after an asynchronous operation, it triggers with the current DOM input value, which is by now outdated (or even some mangled mess, if you kept typing)
The main issue here is that the actual search value should be tracked. You want to debounce the search action, not the value change itself (and certainly not the input change events)
Handle the debouncing ourselvesHere is an alternative to your app, that does the following:
- Keeps a v-model -
search
- no debouncing - On change of said v-model:
- If a search is currently underway, immediately cancels it
- Triggers a debounced search action (which will only actually start when typing stops)

I don't find, how I can get Python variable, use Grunt.
What I need to learn, that solve this task?

ANSWER
Answered 2018-Apr-18 at 14:00Directly reading/running Python in JavaScript isn't really something that is easily done.
You could load the Python value as a string and manually parse it. However, I would highly recommend avoid doing this, as it either requires you to have a really simply Python file, or a really complicated string parser.
Instead, I'd recommend picking a format that can easily be read by both. JSON
is always a good choice when dealling with JavaScript and is can be read in natively:

I use Vue.js CDN and I put all the Vuejs code inside a script tag in index.html. It works fine. However, I'd like to use this component to add tags functionality.
This is how my code looks like:
...ANSWER
Answered 2018-Feb-13 at 14:59You should load the script where VTagInput
is located in your head, right after Vue. Then no need to import anything, VTagInput
will be accessible globally
