QUESTION
Having such a simple js app:
index.html:
...ANSWER
Answered 2021-Apr-14 at 16:42Inside js1.js the function execute a promise that is asynchronous and you want it to wait for the Promise's result :
document.getElementById("app3").innerHTML = await myPromise;
At this point, the function will stop and wait for the "myPromise" to complete (resolve or reject). More on : https://developer.mozilla.org/fr/docs/Web/JavaScript/Reference/Operators/await
The function inside js2.js do not executes code that block it's execution, myDisplay2 can be executed in a synchrone way, the result of the promise will be executed later (if the promise resolve) in the :
.then(function (resp) { document.getElementById("app1").innerHTML = resp; });
To make it short, as soon as you are using "await" the function is "async".

I want to evaluate a javascript in Webview Android as given below in the code. I want to evaluate it after 3 seconds. It works, it gets evaluated after 3 seconds but it(the code inside run()) keeps repeating after every 3 seconds in an infinite loop. I just want to evaluate it once after 3 seconds

will make onPageFinished
to be called further, in which you are setting, again, your Handler
simplest way to avoid this is introducing some boolean
which will be flagged after evaluating JS and prevent second and further calls
QUESTION
I have a website which we moved from custom cms to WordPress about 2 years ago, and for the purpose of getting the old page rank back I want to set up redirects with mod_rewrite
, because some page links did change, so here is my case:
- Old page was not secure, so we moved to https
- WordPress uses W3 Total Cache and Yoast SEO plugins (if that changes anything)
- Domain is the same as it was
- Final URL needs a trailing slash for a page to display properly
So basically I want to do the following (beware of minor changes in URLs):
- Redirect
http://example.com/category_one
tohttps://example.com/category-one/
. - Redirect
http://example.com/category_one/sub_page_one
tohttps://example.com/category-one/subpage-one/
.
I managed to get the first of those redirects working, but the second one doesn't get rewritten, but my knowledge is limited here, so I'd be happy of a working example on how to "chain" both rewrites.
EDIT:
Here is my current .htaccess
:
ANSWER
Answered 2020-Sep-19 at 01:49I managed to get the first of those redirects working
Although there's nothing in the .htaccess
file you posted that appears to do this?
As you can see, I tried with normal Redirect, but what happens is URL
http://example.com/category_one/sub_page_one/
redirects tohttps://example.com/category-one/sub_page_one/
Again, the directives you posted in the question won't perform such a redirect?! There's nothing that specifically redirects HTTP to HTTPS? So, if you are seeing such a redirect you are either seeing a cached response or WordPress itself is performing this redirect. (Although the category-two
redirect(s) would produce such a result since they are in the wrong order - see below).
(Aside: In your example URLs you appear to be converting underscores (_
) to hyphens (-
) in the URL-path, however, you don't state this as a requirement and the resulting URL in your last (edited) example still contains underscores. So, I assume this is not a specific requirement and that source and target URLs can simply be different.)
You should avoid mixing mod_alias Redirect
directives and mod_rewrite RewriteRule
directives. The simpler Redirect
directive is prefix matching and always executes after mod-rewrite, despite the apparent order in the config file.
The order of these directives can also be important. They may need to be in order of specificity (depending on the directive and/or regex used). If there is any ambiguity then the most specific rule needs to be first.

I am making a shopping cart using Vuetify's current CRUD Datatable UI Component (compatible with Vue.js2), and I'm trying to add a type="number"
text-field for both columns quantity
and price
and link them to their respective value to calculate their total.
Here you can see how it can add, calculate a total from 2 static values (which I was using temporarily to test the subtotal calculation with a computed function), and delete with no problem in the following code:
HTML:

Answered 2020-Jun-23 at 04:55You just need to add template inside the table tags just like what you did with the delete icon, You need to make sure that it has it's v-slot

QUESTION
I am making a shopping cart using Vuetify's current CRUD Datatable UI Component (compatible with Vue.js2). I previously had a problem to calculate the total of a product by multiplying the product's quantity with its price. Fortunately, I was given a great solution by using a computed function detailsWithSubTotal()
to calculate the total and replacing the datatable's :item
value (previously "details"
) to :item="detailsWithSubTotal"
as you can see in the following code:
HTML

Answered 2020-Jun-22 at 22:12You can try to add detail
itself to a computed item as a link to an original item and use it to delete from the original details
