按钮onclick（）事件不应该打开链接

Question

This may sound weird, but I want to have a button with a link that does not open when the users clicks it:

<a href="http://mysite.nl/test.php?value=snow"> click</a>

I want to do this because this link has PHP values to recreate the page. The button is on with a new background colour.

I can't just use

document.body.style.backgroundColor='Snow'

because the page auto reloads and I want the colour to stay 'snow' even when the page reloads.

Can this be done? Are there better ways to permanently change the style by the click of a button?

Answer 1

You can use php SESSION for this

$_SESSION['color']='snow';

and take the value from from session by each reload. And use preventDefault() for prevent the link redirection by using javascript
