Call external Javascript function from react components

Question

Im not sure if this has been asked before or anybody has encountered the same issue on reactjs. So the scenario is like this, I have an index.html file that include

Answer 1

Try this solution to call global functions from React with TypeScript enabled:

Either in index.html or some_site.js

function pass_function(){
  alert('42');
}

Then, from your react component:

window["pass_function"]();

And, of course, you can pass a parameter:

//react
window["passp"]("react ts");

//js
function passp(someval) {
  alert(`passes parameter: ${someval}`);
}
