TypeError: csv is undefined

Subject of the issue

I love your library and I DEARLY want to use it, but it seems to have a problem loading in Firefox on client side.

Environment

• Platform: Browser
• Version: Firefox (up to date as of 2018/04/10)

Steps to reproduce

• in the html: <script type="text/javascript" src="js/jquery.csv.js"></script>
• in the index.js: var result = $.csv.toArrays(getTableString("docs/ef-fc-db-stringReadable.csv"));

Expected behavior

jquery-csv loads properly, result variable contains the 2-d array from that string

Actual behaviour

TypeError: csv is undefined - jquery.csv.js:169:9

[evanplaice]

The likely cause is that some library is loaded after jquery-csv that deletes or mutates the $/jQuery namespace

The load order should be:

1. jQuery
2. jquery-csv

Attaching to global namespaces in general is a ‘bad’ idea and will likely become an anti-pattern of developing JS libraries going forward. This library functioning as an extension of the jQuery namespace is an unfortunate artifact of the time it was originally written.

There are plans to provide to re-implement it as an ES module, completely independent of jQuery once ESM support is fully stable and available in browsers/node.

@jonathansekela Hey I was facing the same issue and discovered that it was because the argument passed to $.csv.toArrays() was undefined, check what your <<getTableString(“docs/ef-fc-db-stringReadable.csv”)>> is returning.
