Most of the function had to run by adding a parameter but in this case I just want to work like this:
let value = "test";
value.funcTest();
function funcTest(){
return "value replaced" + value;
}
instead of
let value = "test";
value = funcTest(value);
function funcTest(x){
return "value replaced" + x;
}
is there a way to pull this off?
Given
let value = "test";
value.funcTest();
It's only possible if you add a method to String.prototype - which is a very bad idea and shouldn't be used.
String.prototype.funcTest = function() {
return "value replaced" + this;
}
let value = "test";
console.log(value.funcTest());If you want to tie the string and a function together without using a function call of a separate identifier, a better approach would be to use an object instead, and put both in the object.
const obj = {
value: "test",
funcTest() {
return "value replaced" + this.value;
}
}
console.log(obj.funcTest());I'm not entirely sure what you're trying to do, but maybe using an object would work:
let variable =
{
value: 'test',
funcTest: function()
{
return 'value is ' + this.value;
}
};
If you don't want to have to add the parentheses you could also use a getter:
let variable=
{
value: 'test',
get funcTest()
{
return 'value is ' + this.value;
}
};
This way you could just call variable.funcTest and it would do the same thing.
