my javascript Application works on firefox and chrome very well. But it seams to be broken on Internet Explorer (IE 8).
I did not get an error Message on the console-log. By debugging the code I notice, that the application breaks on the following line:
series.reduce(visit, []);
The whole function exits at this point.
I know, that reduce works for arrays, but console.info(typeof(series)) tells: object
But this object exactly looks like an array - and it works on FF/Chrome. Could this be the reason, why IE stops processing the function at this point? And: how to handle this at IE?
Thank you.
Reduce is not supported until IE 9 : https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/array/reduce#Browser_compatibility
That link does have a workaround bit of code for browsers that don't support reduce.
You can also find other ES5 JavaScript array functions polyfills here:
