eslint: disable warning - `defined but never used` for specific function?

Question

So I have this function:

function render(){     // do stuff } 

I do not call that function, because it is called from html as an event function, like:

<textarea id="input" class="input-box" onkeyup="render()"></textarea> 

Well eslint does not see that, so it gives that warning (render is defined, but never used). Is there a way to specify that function is called elsewhere? Or just mute the warning?

For example if global variable is used, I can do /* global SomeVar*/ and it will mute warning of not defined variable. Maybe something similar could be done on functions like in example?

Answer 1

Provide a config comment telling it to ignore that rule (defined but never used is the no-unused-vars rule)

function render() { // eslint-disable-line no-unused-vars     // do stuff     var x; // still raises defined but never used } 

Answer 2

If you dont want to change the code.

ESLint provides both a way to disable, both to enable the linting via comments. You only added before functions /* eslint-disable */ and after functions /* eslint-enable */

Example

/* eslint-disable */ <-- Before function  function render(){    // do stuff }  /* eslint-enable */  <-- After function
