Hi all experts,
I try to use btob in my js to export html's table to excel.
i added this code in my js
base64 = function (s) { return window.btob(unescape(encodeURIComponent(s))) }
but for this code, it works only Firefox,Chrome and it doesn't work with IE.
When i debug IE, it displays me an error like this: Object doesn't support property or method 'btob'
I found that this method "btob" is for firefox, chrome to use only.
so does anybody know that how can do or replace this method to let IE,Chrome,Firefox work?

Thanks

TONY

Where did you get this 'btob'? If you are asking how to replace a method, don't you think you need to explain what you want to achieve?

UPDATE

Export table data to Excel using jQuery

NOTE: If you need to work above code on IE then,

Quote:
you need to set response header. If you are using ASP.NET then

Response.AddHeader("Content-Disposition", "attachment;filename=download.xls");

I hope this will help to you.
