kandi X-RAY | value-string Summary
ValueString allows you to serialize an object as a culture-invariant string and parse it to any type that implements the Parse/TryParse pattern. It is intended to be used for convenience when there is a need to initialize typed instances from culture-neutral (invariant) strings - often read from a simple configuration file or a database table that contains configuration data as strings.

// ValueString uses the invariant culture when converting
// objects to string if they implement IFormattable.
// So the following value contains "1.5" (dot-separated) even if (1.5).ToString()
// returns "1,5" (comma-separated) due to the current cul

QUESTION
There is a very long select-box in my html document. Every option has got an own name. I want to convert the value-string of the selected option into a javascript-variable. Or do I have to do it with a switch-case-query? Example:
...ANSWER
Answered 2020-Nov-05 at 17:25You can select the value by looking at the event.target
. To quote the official documentation...
The target property of the Event interface is a reference to the object onto which the event was dispatched. (Source: MDN Web Docs: Event.target)
Since event.target
is the element that triggered the event, so looking at its attributes should work (whether you want value or name attribute). You can even make up your own data-attributes

QUESTION
I want to create an adjacency matrix. The matrix should show how many identical Value-strings there are per keyword.
My current approach with two for loops takes a while when working with more data. I have looked into foreach package but could not get my head around for this example. I would appreciate your help for any speed gains ;)
...ANSWER
Answered 2020-Apr-08 at 11:20It's not clear to me whether your real data starts as df

which should speed things up somewhat.

Answered 2020-Mar-13 at 04:41When Xcode says that a type or expression is ambiguous without more context, the compiler is letting you know that the expression you have provided is not specific enough, and it cannot be evaluated properly unless you give it more context (i.e. make it more specific).
In your specific case, it is complaining because you're trying to initialize a Double from an optional String . If you unwrap it, it should remove the warning:

My application dictates need of an argument provider trait
that can be added to any class
to allow passing of arbitrary number of arguments of any type with it.

Answered 2018-Feb-20 at 12:51You're having problem with type-erasure: The Option[Long]
actually store the String "value-string-arg" and doesn't care about its type which as been erased.
However, if you do optLong.get
it will then try to cast it to a Long which is the expected output. And you'll get the ClassCastException
