Actionscript – Restrict numbers 1-10 in textInput Box in Flex

actionscriptactionscript-3apache-flexflex3flex4

I have a TextInput box. I have to restrict a range more than 1,2,3,4,5,6,7,8,9,10 numbers only in the text Box.If i enter any number above that it should be allowed. If enter 11 or more than that, it should not allow to enter. it should allow from 1- 10 digits in the text box.
If enter 11 or 0 it should not allow and more than 10 should not allowed.

Please help me how to restrict it in TextInput Box in Flex. If any one knows about thte regular expression, please help me out .

If the only thing that the user can input are numbers 1 to 10,
try using the NumericStepper component instead.

This component has the features you describe built in.

For example:

<s:NumericStepper minimum="1" maximum="10" value="0" stepSize="1" maxChars="10"/>

Where:

minimum is the minimum allowed value
maximum is the maximum allowed value
value is the initial value
maxChars is the amount of characters allowed
stepsize is the amount by which the amount can be increased or decreased with the arrow buttons

Regex – Regular expression to check comma separted number values in Flex

Your example data consists of three decimal integers, each having an optional leading plus or minus sign, separated by commas with no whitespace. Assuming this describes your requirements, the Javascript/ActionScript/Flex regex is simple:

var re_valid = /^[-+]?\d+(?:,[-+]?\d+){2}$/;
if (re_valid.test(data_string)) {
    // data_string is valid
} else {
    // data_string is NOT valid
}

However, if your data can contain any number of integers and may have whitespace the regex becomes a bit longer:

var re_valid = /^[ \t]*[-+]?\d+[ \t]*(,[ \t]*[-+]?\d+[ \t]*)*$/;

If your data can be even more complex (i.e. the numbers may be floating point, the values may be enclosed in quotes, etc.), then you may be better off parsing the string as a CSV record and then check each value individually.
