JSF currencySymbol

[Mathew Lee]

Hi,

I am trying to understand following code but could not understand.



<h:inputText id="sal" value="#{ManagedBean.sal}">
<f:convertNumber currencySymbol="$" type="currency"/>
</h:inputText><br>
<h:message for="sal" style="color:BLUE"/>
<h:outputText value="#{ManagedBean.sal}">
<f:convertNumber currencySymbol="$" type="currency"/>
</h:outputText>


Especially what currencySymbol is doing.

Please advise. Any links, ideas, suggestions, sample code, resources highly appreciated. Thanks in advance

Well, you understand that currency means money, right? Money amounts are basically numbers, usually preceded (or succeeded) by currency symbols. So the numeric value in the managed bean will be converted to a string in HTML that has a dollar sign in front of it. That's all. Nothing too complicated going on there.

By the way, the current best practice is to use currencyCode instead of currencySymbol.

Also, when you declare a converter for currency, by default it uses whatever currency symbol is in effect for the locale. An explicit "currencySymbol" attribute overrides this.
