Question, maybe i missed it: Its nice you can format the view like that, but what about the actual value in the component? Will the form submit a string now cause of the formatting? I'm having the problem that I want the user just to see the formatted value in the form, but if he submits it of course I just want to submit the actual number, not a string with currency symbols etc. ...
Yes, you need to convert that string value to number in your onSubmit() function. You can use Object.assign(o, form.value) to make a copy of your form.value, and then write some code to change o, so strings become numbers (regular expression + Number() or parseInt() can handle that easily). You need to make a copy because you do not want to mess up your display on front end.
@@turingcs2001 Actually, If we have precisions like 123.4567, and need to show as 123.457% with roundoff three precision and percentage symbol, by this approach the form control value is getting changed as '123.457%'.
It all worked out, thank you! But if you output the data to the html page {{ this.myForm.value | json }}, you'll see that the data changes in the model too. How can I make the data change only in the input?
This is good but it doesn't work if your input is of type number. You can do this to get rid of the currency symbol: this.currencyPipe.transform( form.fieldName, 'GBP', '', '0.2-2' ); or you could also just use the DecimalPipe the same way but the number won't display if you have thousand separators. you could change it to string and do the conversion on save to strip then convert to a number again but you lose the browsers number support e.g. mousewheel or up down arrows to change value. Probably not an issue for your scenario but it could be in other cases
Hello wang, This solution is amazing , but I am facing issue when I try to enter a value like 12345.67 .. It’s not accepting the ‘. ‘ decimal when entered manually but if I enter decimal point after entering the whole number , it is accepting
The example I supplied only works on whole dollars, not cents. Under section 'use pipe to display currency' (1:33), I wrote custom code (using regular expression) to remove 1. all leading zeros 2. anything non-digit. That's why '.' got removed. You need to modify my code to allow '.', and also change the currency pipe specification ('1.0-0' is for whole dollars only).
This is Angular, not Excel. If you want to display $ on the right hand-side, you probably need to make your own pipe because I doubt the built-in currency pipe has dollar displayed on the right setup.

@@isrozuna1586 you need to read currency pipe documentation to find out the correct argument. Try removing the 1.1-0 argument. I believe the default format shows cents.
hello dear friend! thank you for your tutorial. but I need this for controls I mean for form details. not for the main form I want to do this for details of a main form.
Well it does format the values correctly, but also puts the input-cursor always to the end of the value, which makes modifying values in the middle and front exhausting. Is there a fix for that?
Also, moving cursor to the end is the right default choice. If you move cursor to the middle or front by default, people will find it exhausting when they want to edit the end.

I guess your question is related to localization. You can use the getLocaleNumberSymbol function in order to get **your current locale's** grouping and decimal characters and then adjust the regular expression with this characters (instead of hardcoding , and .

In Reactive Form Controls Can't we use pipe in Html?
very useful. Tnx
By this approach, the form control value is changed as string with comma separated, but we need to save as number. Is that possible?
You have to write code to parse string to number

One great solution, thanks
The specified value "$1" cannot be parsed, or is out of range please help me , I am getting this error
Nice!
This is good but it doesn't work if your input is of type number.
You can do this to get rid of the currency symbol:
this.currencyPipe.transform(
form.fieldName,
'GBP',
'',
'0.2-2'
);
or you could also just use the DecimalPipe the same way but the number won't display if you have thousand separators.

thank u so much
Using a directive is cleaner.
can you elaborate more on this approach?

Use regular expression .replace(/\D/, ‘’) to remove non-digits and parseInt() to convert to number. JavaScript 101

agreed
You can subscribe to onBlur event, so nothing happens until the user mouses away
Also, moving cursor to the end is the right default choice. If you move cursor to the middle or front by default, people will find it exhausting when they want to edit the end.

form.newWorth.replace error replace is not a function
replace() is a function on a string. your newWorth is probably a number so it doesn't have a replace function.
