前言

在HTML5的世界中,之所以有框架的出现,是为了能够方便快捷的开发出我们想要的产品,今天我们来讲一下SAPUI5中一个非常重要而又比较常见的语法——$运算符在xmlView中的使用。

判断语句

不多说,直接上代码:

<!--Set to visible if the status is critical and the amount is above the threshold (note escaping of &&)-->
visible="{= ${status} === 'critical' &amp;&amp; ${amount} > 10000 }"
<!--Text for amount level using language-dependent texts from the resource model.-->
text="{= ${/amount} > 10000 ? ${i18n>/high} : ${i18n>/normal} }"
<!--Set to visible if the rating is VIP, ignoring case or if the order amount is greater than 10,000.-->
visible="{= ${/rating}.toUpperCase() === 'VIP' || ${/orderAmount} > 10000 }"
<!--Set to visible if the rating contains VIP, ignoring the case. -->
visible={= RegExp('vip', 'i').test(${/rating}) }
<!--Text is maximum of three values.-->
text="{= Math.max(${/value1}, ${/value2}, ${/value3}) }"
<!--Control is enabled only if the order status is set.--> 
enabled="{= ${/orderStatus} !== null }"
