lua.vm.js innerHTML error

Question

我得到了以下lua.vm.js代码:

local data=tostring(js.global.Module.read('/statsWidget.lcgi'))
print(data)
print(js.global.document.getElementById('statsWidget').innerHTML)
js.global.document.getElementById('statsWidget').innerHTML=data

虽然ajax调用和两个打印工作正常，试图设置innerHTML引发一个javascript错误:

我做错了什么?

Answer 1

我无法验证您的数据，但对我来说这是有效的:

-- working
js.global.document:getElementById('statsWidget').innerHTML= "foo"

如果失败:

-- not working
js.global.document.getElementById('statsWidget').innerHTML= "foo"

注意文档后面的冒号。它为函数添加了一个隐藏的self参数:

-- working too
js.global.document.getElementById(js.global.document,'statsWidget').innerHTML= "foo"
