里面的不起作用( inside doesn't work)

里面的不起作用( inside doesn't work)

我想用货币值做输出文本：

<h:form rendered="#{not empty cartBean.cartMap}"> <h:outputText escape="false" styleClass="cart-text" value="Your shopping cart: &lt;b&gt;#{cartBean.cartDishesCount}&lt;/b&gt; items, total= &lt;b&gt;#{cartBean.updateTotalPrice()}&lt;/b&gt;"> <f:convertNumber currencyCode="USD" type="currency"/> <!-- todo - don't work --> </h:outputText> </h:form>

但<f:converNumber>忽略并且页面输出仍然如下所示： Your shopping cart: 9 items, total= 46.800000000000004

I want to do output text with value of currency:

<h:form rendered="#{not empty cartBean.cartMap}"> <h:outputText escape="false" styleClass="cart-text" value="Your shopping cart: &lt;b&gt; #{cartBean.cartDishesCount}&lt;/b&gt; items, total= &lt;b&gt;#{cartBean.updateTotalPrice()}&lt;/b&gt;"> <f:convertNumber currencyCode="USD" type="currency"/> <!-- doesn't work --> </h:outputText> </h:form>

but <f:converNumber> is ignoring and page output still looks like this:

Your shopping cart: 9 items, total= 46.800000000000004

最满意答案

尝试只有值中的值

<h:outputText value="#{cartBean.updateTotalPrice}" > <f:convertNumber currencyCode="USD" type="currency" /> </h:outputText>

转换数字需要一个数字，因为outputText的值是一个字符串，它不会识别它。

任何不是数字的东西都会单独显示。

如果你想明确指定位置，那么这是一个选项

<f:convertNumber type="currency" currencySymbol="$" locale="en_US" />

Try to have only the value in the value as in

<h:outputText value="#{cartBean.updateTotalPrice}" > <f:convertNumber currencyCode="USD" type="currency" /> </h:outputText>

The convert number expects a number, since the value of the outputText is a string, it does not recognize it.

Anything that is not the number would be displayed separately.

If you want to explicitly specify the location then this is an option

<f:convertNumber type="currency" currencySymbol="$" locale="en_US" />
