eslint：禁用警告-特定 function 的“已定义但从未使用”？

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?

Just put this rule in.eslintrc.js file, please don't forget to restart serve..

module.exports = {
      rules: { 
        "no-unused-vars": "off",
      },
    }

Pretty similar to what Alex K. is proposing, there is also eslint-disable-next-line . I generally prefer that to not make the method definition line of code too long. You can use it like this:

// eslint-disable-next-line no-unused-vars
function render(){
    // do stuff
}

You can add the argsIgnorePattern option specifies exceptions not to check for usage: arguments whose names match a regexp pattern. For example, variables whose names begin with an underscore.

/* eslint no-unused-vars: ["error", { "argsIgnorePattern": "^_" }]
   @typescript-eslint/no-unused-vars: [1, { vars: 'all', 'argsIgnorePattern': '^_' }] */


function foo(x, _y) {
    return x + 1;
}
foo();
