Hello,
I've been working on creating a script that zooms the entire webpage. Other than using "CTRL" + "+" keys (generally compatible with all browsers) to zoom in inside a web browser, I want to put it in a different format, as a button; it would be even easier to use.
The problem is that I can't figure out how to make it work/ why it does not work. The following is my code:
Code:
<html>
<head>
<script type = "text/javascript">
document.onkeydown = function(zoomin) {
var key;
zoomin = zoomin || event;
key = zoomin.keyCode;
key == 43;
return false;
if (key == 17) {
return true;
function(zoomin){;
return false;
}
}
}</script>
</head>
<body>
<h1>Is this appearing to get bigger?</h1>
<button onclick="javascript: function('zoomin');">Zoom in</button>
</body>
</html>
Basically I was trying to use a DEC code as the code for the "CTRL" and "+" keys; then put them into a function. The "return true" under the IF statement means that I want it to hold so that the "+" key can be read as part of the script, and therefore make the page zoom in. Once that happens, it returns false.
I would appreciate any help/ suggestions. I will also try to look for a way to reset the page (100%) or zoom out as well.
