Changing a button's onclick and stay()

[itrollmework 0]

function changeBtn(btn)
{
if (! btn.style)
{
alert("Big no for you and dont ask y, just cant do it D:");
return;
}
btn.style.background = "#00FF00";
btn.style.color = "black";
return;
}

<input type="button" id="btn1" value="glowwwww!!!" onclick="changeBtn(this)"></td>

so i found this code on the internet, and it is very useful...

sadly.... every time i refresh the page the button will go back to default color...

 

how can i make it stay green even tho i refresh the page???

thankyou

This is JavaScript topic, NOT Java, they are different.

 

You cannot truly make it permanent with JavaScript, you can store its current styling using cookie, or using web storage, but if the user clears cache/history it will revert to original state.
