JSLint says “missing radix parameter”

Question

I ran JSLint on this JavaScript code and it said:

Problem at line 32 character 30: Missing radix parameter.

This is the code i

Answer 1

To avoid this warning, instead of using:

parseInt("999", 10);

You may replace it by:

Number("999");

^{Note that parseInt and Number have different behaviors, but in some cases, one can replace the other.}

Answer 2

Instead of calling the substring function you could use .slice()

    imageIndex = parseInt(id.slice(-1)) - 1;

Here, -1 in slice indicates that to start slice from the last index.

Thanks.

Answer 3

Prior to ECMAScript 5, parseInt() also autodetected octal literals, which caused problems because many developers assumed a leading 0 would be ignored.

So Instead of :

var num = parseInt("071");      // 57

Do this:

var num = parseInt("071", 10);  // 71

var num = parseInt("071", 8);

var num = parseFloat(someValue);

Answer 4

You can turn off this rule if you wish to skip that test.

Insert:

radix: false

Under the "rules" property in the tslint.json file.

It's not recommended to do that if you don't understand this exception.

Answer 5

Adding the following on top of your JS file will tell JSHint to supress the radix warning:

/*jshint -W065 */

Answer 6

Simply add your custom rule in .eslintrc which looks like that "radix": "off" and you will be free of this eslint unnesesery warning. This is for the eslint linter.
