I want to silence the JSHint warning "attrs is defined but never used" for the variable attrs
. However I do not want to use the option /* jshint unused:false */
since this will turn off the warning altogether. I want the warning to be disabled only for attrs
.
Add
/* exported variableNameHere */
at the top of your script. In your case, replace variableNameHere
with attrs
. This tells jshint that attrs
will be used elsewhere.
For multiple variables:
/* exported attrs, somethingElse, somethingElse2 */
Docs here.
You can ignore all unused local variables within a given function scope using the method outlined in this jshint commit and this GitHub issue. Example:
//jshint unused:true
var a;
function foo(b) {
//jshint unused:false
return 1;
}
foo();
// ->
// Line 1: 'a' is defined but never used.
This doesn't seem to be documented anywhere else, but works when tested on http://jshint.com/
