[英]How to check if an XMLList is empty in Flex
If I have an XMLList object in Flex, what is the proper way to check to see if the list is empty? 如果我在Flex中有一个XMLList对象,检查列表是否为空的正确方法是什么? Should I just compare the result of myList.length() > 0
, myList.toString() != ""
or try another method altogether? 我应该只比较myList.length() > 0
, myList.toString() != ""
还是尝试另一种方法?
I would go with the simple myList.length() > 0
method. 我会使用简单的myList.length() > 0
方法。
You can see an example of the length()
function in the ECMAScript for XML (E4X) specification (page 104), which Actionscript implements. 您可以在ActionsScript实现的ECMAScript for XML(E4X)规范 (页面104)中看到length()
函数的示例。
