问题
I have a javascript file included in the <head></head> tags of my Angular 2 app. I would like to access a function in that javascript file from my typescript file, how should I do that? When I'm running the app, I can type var simplemde = new SimpleMDE() in the browser console to get my markdown editor working, but how can I do this in the constructor in my typescript file?
回答1:
Just declare it at the top of your component or wherever you need it like so:
declare var SimpleMDE: any;
Then you can call it in your constructor like you want!
回答2:
You can use namespacing, which is basically an object and it wraps all other variable & function
Like this
var SomeObject={}
SomeObject.abc = "Some Value";
SOmeObject.myFunction = function(){
// function body
}
In other file you can simply call SomeObject.abc & it will return string Some Value
You should use namespacing to avoid conflict of global window
