In an Angular2 typescript component I have the following local variables
teapot10: boolean = false;
teapot20: boolean = false;
teapot30: boolean = false;
I want to use these dynamically in a function like so
doSomeStuff("teapot20")
doSomeStuff(teapot: string){
this[teapot] = true
}
So in this example I pass the string name of the local variable "teapot20" and I want to use this string to manipulate the actual variable called teapot20.
Can I do this?
Thanks
You better use string literals instead of just a string:
doSomeStuff(teapot: "teapot10" | "teapot20" | "teapot30") {
this[teapot] = true
}
Or:
type PropNames = "teapot10" | "teapot20" | "teapot30";
doSomeStuff(teapot: PropNames) {
this[teapot] = true
}
This way you can make sure that no one calls it like so:
doSomeStuff("tepo10");
