Hi iisboy,

It took me long time to test it and find solution. Sorry for late reply.

The error code is line 10:doc.write "<meta http-equiv='X-UA-Compatible' content='IE=edge' />", not set doc = CreateObject("htmlfile"). But when I tested it in visual studio, all work well.  I don't think it is a problem of code.

You just need to change the identity of application pool to local system, it can work whether IE 8 or 10.

if u not in win7,in 2012 server +, or win7 in IE10+,my little code run very well.i use your way to  change the identity of application pool to local system,Everything as before.So i guess my win 7 or IE8 not support the method "doc.frames.json",the code must run in IE10+.thanks again for you help me ,I thank you from the bottom of my heart.

I find some article later ,then i at last find a Real reason.

Chrome 23, IE 10, and Safari 6 were the first browsers to fully support ECMAScript 5.

Internet Explorer 9 does not support ECMAScript 5 "use strict".

So,if u not use IE10,then the browser will not support ECMAScript 2009, also known as ES5.

the same time ,JSON.parse() will not run in browser ,because JSON.parse() is a ES5 Features.
