Question

我想动态加载片段并拥有以下XML-View：

Uncaught (in promise) Error: resource {= ${/BOOL_VALUE} === 'true' ? 'view/fragment1' : 'view/fragment2'}.fragment.xml could not be loaded from https://sapui5.hana.ondemand.com/1.44.14/resources/{= ${/BOOL_VALUE} === 'true' ? 'view/fragment1' : 'view/fragment2'}.fragment.xml. Check for 'file not found' or parse errors. Reason: NetworkError: Failed to execute 'send' on 'XMLHttpRequest': Failed to load 'https://sapui5.hana.ondemand.com/1.44.14/resources/%7B=%20$%7B/BOOL_VALUE%7…'true'%20?%20%27view/fragment1%27%20:%20%27view/fragment2%27}.fragment.xml'.

at constructor.init (Fragment-dbg.js:469)
at constructor.F._initCompositeSupport (Fragment-dbg.js:135)
at ManagedObject-dbg.js:427

但不知何故，当我加载它时，fragmentName中的表达式不会被评估，并且比较被视为文件名：

import sys
def hello(a, b):
    print "hello and that's your sum:"
    sum = a+b
    print sum

if __name__== "__main__":
    hello(int(sys.argv[1]), int(sys.argv[2]))

我在这里做错了什么？

我认为您不能对属性＆＃39; fragmentName＆＃39;使用表达式绑定，就像您不能使用＆＃39; id＆＃39;或者＆＃39; class＆＃39;你应该使用格式化函数。
