How to disable warnings about 'this' and strict mode using JSHint?

问题

I am writing a web app using AngularJS (v1.5) so I have some controllers, and in those controllers I am often declaring something like :

function myController($someDirectives, ...){
    var ctrl = this;
    // My code
}

The thing is when I JSHint my code, I get this warning message for all of my 'this' declared in controllers :

If a strict mode function is executed using function invocation, its 'this' value will be undefined.

I must precise that in my .jshintrc file, I set "strict":false. Does anyone know how to disable this message in particular?

Thanks in advance.

回答1:

set the configuration in .jshintrc file

{
  "validthis": true // Tolerate using this in a non-constructor 
}

回答2:

You can always override jshint options in the code-block ie.

/* jshint validthis: true */

I had the same issue, with a very similar environment angular 1.5.5 always getting the same lint warning:

If a strict mode function is executed using function invocation, its 'this' value will be undefined.

I've changed the name of my component's main function starting with upper-case and the warning disappeared

function MyController($someDirectives, ...){

I'm having the same issue. I'm doing "indirect invocation" with the function in question, not "function invocation", and 'this' is referenced many times in the function body.

In my case, I was having so many of these "errors" that jsHint quit before scanning my whole script.

To get around this I put this at the top of my script-file:

/*jshint maxerr: 10000 */

It did not suppress the errors, but at least it allowed me to scroll down to see jsHint's analysis of the entire script.
