## Behavior

User click on `Donate` button → was redirected to `Bitcoin-Redirect` page in current tab → was opened bitcoin wallet of user → in current tab was opened page, on which `Donate` button is situated.

## Solution

You need use redirects.

### Source of `Donate` button

	[![Bitcoin Donate Button](http://Kristinita.ru/Donate-files/Bitcoin-Donate-button.png)](http://Kristinita.ru/Donate-files/Bitcoin-Redirect)

If you click the image, you will go to a page **<http://Kristinita.ru/Donate-files/Bitcoin-Redirect>**. See [**answer on Meta Stack Exchange**](https://meta.stackexchange.com/a/38917/326972), how use Markdown markup for this construction. Alternative worked HTML source:

	<a href="http://Kristinita.ru/Donate-files/Bitcoin-Redirect"><img src="http://Kristinita.ru/Donate-files/Bitcoin-Donate-button.png"></a>

### Source of `Bitcoin-Redirect` page

	<script>
    window.location.href = "bitcoin:17uctxtsWG3gpyAy6iJ8AVd5rdSjkJH2?label=In%20the%20treatment%20of%20Sasha's%20teeth&amount=0.0037";
    history.back();
	</script>

Use JavaScript methods [**window.location.href**](http://javascript.ru/window-location) and [**history.back**](http://javascript.ru/window.history).
