How to make working WebGL build?

Hi.

Im testing WebGl. I've created a plane with button on it and make Webgl build. But it not working. Not on local: (some socket number), not on denwer. I've turned Enable exeptions and increase memory size to 1024. But he still trow errors in console. Often different, sometimes it do nothing, just print null and write "Player is loading" when im pressing fullscreen button. For now error is

Invoking error handler due to
SyntaxError: missing while after do-loop body

Is there a some video guide or some text about how to make and build small webgl app with Unity GUI?

 

On 1024 error is:

Invoking error handler due to
SyntaxError: missing while after do-loop body​

or all seems ok, but nothing happens and on header:

200 OK

On 2048 is:

Invoking error handler due to
RangeError: invalid array length
UnityConfig.js (строка 74)


RangeError: invalid array length

var buffer = new ArrayBuffer(TOTAL_MEMORY);​

Is that because 2000Mb is too much?

 

Anyone? For now ill try to download lates Unity (Used 5.0.1f3, ill try 5.1 )/

 

I think all ok with downloading file on server, because it is local virtual Web server called Denwer and i just copy files from one folder to another .
Ive downloaded last Unity version (5.1.0f3 64 bit), also ive installed VCCredist 2012 and cmake. Buildind non Develop with memory cap size 256 and EnableExeptions Explitly Thrown. All work prety fine, no alert js messages, in console there are only one error:

but program with simple script button and input field printing some text to console log works fine.

 

But building it like Development build still call out of memory error. And if you build if agail like non Dev. build all work again. Is development build needs a much more memory?

 

I've set memory size to 512, and Dev build started work without problems too. But there more errors in console:

 

Oh, thanks, sorry for disturbing.
