Safari showing JS error, but Chrome doesn't

I'm quite new to JS. I've been developing a couple of JS function. They work in Chrome. Yesterday I tried it in Safari and it's spitting out errors.

The function:

Request.SetForm = function (form, ruleset = [], messageset = null, focus = null, special = false, ignore = false) {

// Code here

}

I'm calling it like:

var $validator = Request.SetForm(arguments here);

Now Safari says:

ReferenceError: Can't find variable: Request

Well as I said, Chrome doesn't say anything and it works fine. What's wrong here?

Solution

  • Don't forget to declare the Request before using. use

    var Request = {};

    Then use

    Request.method = function(){}

    Because some older versions can't resolve a variable if not declared ( Normally the issue happen when we use in use strict mode.

    Or else, Request may be a keyword or built in method in the version of safari you are using. So just change the name.
