Google Timeline :: Bad version while using gstatic

[shyam.ag...@gmail.com]

Hi,

I have downloaded https://www.gstatic.com/charts/loader.js in my project as lib file to avoid calling JS script dynamically on the fly.

I used below code to generate timeline visualization, 

<script type="text/javascript" src="../lib/loader.js"></script>  -- (static lib folder path in my src code)

<script>

google.charts.load('1.1', {packages: ['timeline']});

google.charts.setOnLoadCallback(drawChart);

</script>

But in console, I am getting Bad version error.

Uncaught (in promise) Error: Bad version: 1.1

    at loader.js:133

When I use below code, it works perfectly.

<script src="https://www.gstatic.com/charts/loader.js"></script>
<script>
  google.charts.load('current', {packages: ['timeline']});
  google.charts.setOnLoadCallback(drawChart);

</script>  

Please let me know how to resolve this.  

Thanks,

Shyam

The loader at  https://www.gstatic.com/charts/loader.js is really just the top-level loader that then redirects to another loader based on which version you are loading as specified with your google.charts.load call.  So you are not escaping the dynamic loading of code by downloading the top-level loader.  Also, the top-level loader does get updated from time to time, at least every time there is a new release, and so it is not a good idea to save your own copy of it.  The support for loading '1.1' was added fairly recently, actually, so if your copy is older, that would explain the failure.

Hi Daniel,

Thank you for providing your input.

Could you please guide me what all libraries I need to download to stick to one version rather than using latest all the time? In my environment, we cannot access library using URL due to security constraints, can you guide me how can I proceed and what should be the version I should use?

Thanks,

Shyam Agrawal

The instructions on how to use the loader are at:   https://developers.google.com/chart/interactive/docs/basic_load_libs

Change 'current' to a particular version number, as described on the Release Notes page:

https://developers.google.com/chart/interactive/docs/release_notes

You can use your browser's debugger to observe all the files that the loader loads into your browser when you visit a page.
