[英]Why can't I require a constructor and immediately use it with browserify?
The two following lines of code should do exactly the same thing. 以下两行代码应完全相同。 The first one is a bit more verbose, but this should be the only difference.
第一个更冗长,但这应该是唯一的区别。 Still, the 2nd example results in an error.
但是,第二个例子导致错误。 Why?
为什么?
The following works: 以下作品:
var Model = require('./Model');
new Model();
However, the following results in Uncaught Error: Cannot find module './Model'
但是,以下结果为
Uncaught Error: Cannot find module './Model'
new require('./Model')();
It has to do with the operator precedence. 它与运算符优先级有关。 If you do this, it will work:
如果你这样做,它将工作:
new (require("./Model"))();
What was happening is: 发生的事情是:
(new require("./Model"))()
