IE8 Object doesn't support property or method 'indexOf'

[Sergey Z]

Hi, today I'm getting following error in IE8: Object doesn't support property or method 'indexOf'

File: recaptcha__en.js, Line: 151, Column: 470 - that maps to following code return a.ua?0<=U(a.ua,5).indexOf("JS_THIRDEYE"):!1}.

This error happens on google side, when I enter window.location.href I'm getting: "https://www.google.com/recaptcha/api2/anchor?hostiemode=8&k=6Lf9zAUTAAAAAGfDJKxCEIRTZpNdS_jPn0IXoB75&co=aHR0cHM6Ly9xYS5pbmRpZ28uY2E.&hl=en&v=r20150812220525&size=normal&usegapi=1&jsh=m%3B%2F_%2Fscs%2Fapps-static%2F_%2Fjs%2Fk%3Doz.gapi.en_US.wqJ91a9E5uM.O%2Fm%3D__features__%2Fam%3DAQ%2Frt%3Dj%2Fd%3D1%2Ft%3Dzcms%2Frs%3DAGLTcCPCICLu5JaHSe0tS4iij8Ln6MXyYg#id=I0_1439799838541&parent=https%3A%2F%2Fqa.indigo.ca&pfname=&rpctoken=32098684"

On Friday recaptcha was working. Looks like code is missing polyfill for ES5 array methods for IE8. Can this be fixed, please?

Thank you.

Hi,

I have the exact same issue with recaptcha__fr.js.

Look like the polyfill exist but don't work for this part of code.

var z = Array.prototype,

        La = z.indexOf ? function(a, b, c) {

            return z.indexOf.call(a, b, c)

        } : function(a, b, c) {

            c = null == c ? 0 : 0 > c ? Math.max(0, a.length + c) : c;

            if (r(a)) return r(b) && 1 == b.length ? a.indexOf(b, c) : -1;

            for (; c < a.length; c++)

                if (c in a && a[c] === b) return c;

            return -1

Having the same issue today as well.

Works in IE8, not in emulating from IE11.

This error is occurring because IE8 does not support indexOf(), see here: https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/Array/indexOf

Hopefully they can rework this code to not use indexOf().

I am also seeing the same issue. Would be great if they could fix this one.

Also seeing this problem on a site that was seemingly working in IE8 until recently.

[David Muñoz Camarero]

Same problem. I have to use reCaptcha old in IE8 while this is broken :(.

[Kyoungmin Kim]

same problem.
I'm considering a migration to reCAPTCHA OLD version.

[Elton Koltun]

I'm having the same problem, it's the second time it occurs

Anyone have a workaround to solve Object doesn't support property or method 'indexOf' issue on IE8? It's still breaking and reCaptcha is not appearing. Do the reCaptcha devs respond to this forums and take up the issues or is there a way to report the error to the core development team? 

Thanks,

Radiant

I'm having the same issue. Has anyone been able to resolve?

a lot of people reporting this issue. I hope it's resolved soon

Interestingly the browser requirements state that only the two most recent versions of each browser are supported.

Hopefully it still gets resolved though as IE8 is still fairly commonly used.
