Start input with a negative charachter

[ulfojebo]

Tried using this package and it works really well.

Would like to discuss the posibility to add a "minus" charachter as the first input in a field.
The users of the system my team is building are used to this workflow when entering numbers.

I made it work on my machine but the question is if you think it should be entered here or if I should fork this project and make my own version for my specific needs.

Thanks!

Hi @ulfojebo!

There's this option: allowNegative - If true can input negative values. (default: true).

If you type 88 and then hit the minus button on the Keyboard the output becomes -88.00 (depending of your current config).

The minus charachter also appears for the user in front of the current prefix.

Is this a solution for your case?

[ulfojebo]

I know that it is possible to enter negative numbers that way but it seems unnatural.
For now I have made a small change and made it work. When you enter the first minus the value is NaN but other than that I don't see any side effects.

changeToNegative(): void { if (this.options.allowNegative && this.rawValue != "" && this.rawValue.charAt(0) != "-" && this.value != 0) { this.rawValue = "-" + this.rawValue; } if (this.rawValue.charAt(0) != "-") { this.rawValue = "-"; } }

+1 to @ulfojebo request
Also, thanks for the provided solution. Spent so many of hours searching for an alternative to avoid changing the core code but this seems to work.

I have a same issue.
I have tried @ulfojebo code and it works correctly.
I hope to merge his code into main trunk.
Thank you.

Having the same issue. And of course -- it will be very helpful and made the lib more solid. Please merge it into main branch.

@ulfojebo @betodasilva did you guys just clone the lib locally and made those changes in the changeToNegative? Or are there any other workarounds?

+1 to @ulfojebo request. I also have clients who are used to entering the negative sign as the first value when entering a negative currency value. This feature would absolutely make the lib more solid.

changeToNegative(): void { if (this.options.allowNegative && this.rawValue != "" && this.rawValue.charAt(0) != "-" && this.value != 0) { this.rawValue = "-" + this.rawValue; } if (this.rawValue.charAt(0) != "-") { this.rawValue = "-"; } }

great, this is working once we edit the core files, @nbfontana could you please take a look at this , it becomes a very important feature now.

This is a deal-breaker for us too. I used the above fix and it worked. but modifying the library is not a sustainable solution.
