Restricting TextInput value to 5 decimal points

[Amruta Kulkarni]

Hi All,

 

I am working on a flex application which has requirement to restrict user to enter the numbers with 5 decimal places only.I tried the 'restrict' property of TextInput control.Here is the code snippet that I tried:

 

<mx:TextInput id="txtValue" restrict="[0-9]*\.?[0-9]{0,5}" />

 but this is not working.Can anyone help me out on this?Its very urgent.

 

Thanks

Hello Amrutha,

If my understanding from ur below snippet is correct your trying to use the text input only for decimal places, if yes use maxchars to 5 and restrict from 0 to 9.

If your requirement is to have the same text input for both the integer and decimal ,  build simple custom component extending textinput to do this validation.

Cheers,

Naveen

Hi Amrutha

You can use Number Validator

Look following code

<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx">
<fx:Script>
</fx:Script>
<fx:Declarations>
<mx:NumberValidator id="numV" source="{sampleText}" property="text"
trigger="{myButton}" triggerEvent="click" domain="real" precision="5"
precisionError="Decimal Should Not be morethan 5"/>
</fx:Declarations>
<s:layout>
<s:VerticalLayout/>
</s:layout>


<mx:TextInput id="sampleText"/>
<mx:Button id="myButton" label="Validate"/>

</s:Application>

Hi
You need
to use max chars property as 5 and  0-9 in restrict property then i think solves your problem

[Amruta Kulkarni]

Thanks all for your suggestions & solutions.I solved the problem using regular expression validator.

Hi All,
Can u please help me out in the same.
I have a similar case where i need to create a regular expression where there is a number with three decimals followed by forward slash then again a number.

eg. 12.123/12/34.1234

It should trim number 4 from the decimal or else show an alert message entry is wrong.

You can try using MaskedTextInput as given below

<ns:MaskedTextInput maskText="##.###/##/##.####"/>

Then you can write your logic to split the text based on the delimiter.

Thanks,
