webcomponents.js (and min.js) error in Safari (with polymer versions 0.5.3 & 0.5.4)

[Kelly St. John]

I'm currently using polymer version 0.5.4, and receiving the following console error in Safari 5.1.7, specifically relating to webcomponents.min.js:

ReferenceError: Can't find variable: Window (webcomponents.min.js.11)

When I switch over webcomponents.js, I receive the following error:

SyntaxError: Cannot declare a parameter named 'textContent' in strict mode (webcomponents.js:1948)

The site runs fine in Chrome v40.0, and IE 11 (albeit slow in IE) without any errors.

Any suggestions?  Is this a known issue?  I noted comments relating to a fixed Polyfill in Safari for Polymer 0.5.4, but it doesn't seem to have resolved the issue in my case.  I should also note that this Safari issue only began with Polymer version 0.5.3.

Hi Kelly,

Polymer only supports the evergreen browsers -- the latest versions of Chrome, Safari, IE and Firefox. According to the browser compatibility page, that includes Safari 6+.

https://www.polymer-project.org/resources/faq.html#browsersupport

The problem fixed in 0.5.4 was an issue that affected Safari 7 & 8.

My bad...when I recently downloaded the latest available Safari for Windows for testing purposes, I failed to realize the version was so much older than the current versions available for Mac & iOS...

I suppose then, the only way to truly test is on an actual Apple device with a more recent version of Safari.

Thanks!

Yeah, I'm afraid so -- they discontinued Safari for Windows in 2012, I think. And unlike IE, they don't provide prefab VMs for testing Safari.

There are some services that let you do testing online.  I've used Browserstack (http://www.browserstack.com/), for example, which lets you test on a variety of 

OSes and browsers.

Cheers,

Arthur
