Doublebox
Employment/Purpose
An edit box for holding an float point value (double).
Example
<doublebox value="2.3"/>
Properties
Format
You are able to format the field by providing specifying the attribute with a formatting string. The default value is null.
<doublebox format="#,##0.##"/>
Constraint
You could specify what value to accept for input controls by the use of the constraint property. It could be a combination of no positive, no negative, no zero, no empty.
To specify two or more constraints, use comma to separate them as follows.
<doublebox constraint="no negative,no empty"/>
If you prefer to display different message to the default one, you can append the error message to the constraint with a colon.
<doublebox constraint="no negative: it shall not be negative"/>
Notes:
- The error message, if specified, must be the last element and start with colon.
- To support multiple languages, you could use the 「l」 function as depicted in the Internationalization chapter.
<doublebox constraint="no negative: ${c:l('err.num.negative')}"/>
