Sorry, I tried to execute this code from Internet Explorer 11. Its not working. Can you please make it work in IE 11??? Waiting for your response

Thank you. This is working well but only for the first page of a table - just the visible view.
Is there a way to tweak this to export the entire table?

@Raverito, @AShakthivel check out my fork https://gist.github.com/kalebdf/ee7a5e7f44416b2116c0/revisions#diff-eacf331f0ffc35d4b482f1d15a887d3bR135
Do a check for IE window.navigator.msSaveOrOpenBlob and then use the Blob object for IE.

Thanks very much.

ghost commented Aug 4, 2016

Hi guys,
i have a question, if someone can help me.

I did a the feature that downloads a csv file with javascript in my application.
It works good till 5000 rows circa, after that when i try to download the file the browser gives me a "Connection Error" .. but actually it isn't a network error because i have already ALL the data before to make the CSV string.

Thanks in advance,

Nico

if($text=="\xa0") { $text = ''; }

I tried to add $("#export").click(); on the end but it isn't downloading. What I supposed to do is when I refresh the page, it should automatically download the file.

I have question also here
