Prevent user from copying text on mobile browsers
Try putting a transparent div over the text. I have used jQuery here. That should work.
var position = $('#textInHere').position();
$('#noClickThroughThis').css({
height: ($('#textInHere').height()),
width: ($('#textInHere').width()),
position: 'absolute',
top: position.top,
left: position.left,
'z-index': 100
});
Here is a fiddle http://jsfiddle.net/lacrioque/tc4bwejn/
You can simply make the text into an image.
<style type="text/css">
div.image {
width: 100px;
height: 100px;
background-image: url-to-your-image;
}
</style>
To generate the images you can use a server side script as in the aswers of this question
or something like this:
<?php
header("Content-type: image/png");
$im = @imagecreate(210, 30)
or die("Cannot Initialize new GD image stream");
$background_color = imagecolorallocate($im, 255, 255, 255);
$text_color = imagecolorallocate($im, 0, 0, 0);
imagestring($im, 4, 5, 5, "This is a test", $text_color);
imagepng($im);
imagedestroy($im);
?>
Test here
You can prevent the user from actually selecting the text so it can not be copied - however I'd still combine this with paste detection as others recommended
.noselect {
-moz-user-select: none;
-webkit-user-select: none;
-ms-user-select: none;
user-select: none;
}
<p>this can be selected</p>
<p class="noselect">this can NOT be selected</p>
But the user can still open the page source and copy it from there.
One crazy way of doing this is, laying out another absolutely positioned element on top of this. But this will disallow clicking of links too! May be you can do it with position: relative
and a higher z-index
.
.content {position: relative;}
.content .mask {position: absolute; z-index: 1; width: 100%; height: 100%;}
.content a {position: relative; z-index: 3;}
<div class="content">
<div class="mask"></div>

Try using the touch
or longpress
events.
<!DOCTYPE html>
<html>
<head>
<script>
function absorbEvent_(event) {
var e = event || window.event;
e.preventDefault && e.preventDefault();
e.stopPropagation && e.stopPropagation();
e.cancelBubble = true;
e.returnValue = false;
return false;
}
function preventLongPressMenu(node) {
node.ontouchstart = absorbEvent_;
node.ontouchmove = absorbEvent_;
node.ontouchend = absorbEvent_;
node.ontouchcancel = absorbEvent_;
}
function init() {
preventLongPressMenu(document.getElementById('theimage'));
}
</script>
</head>
<body onload="init()">
<img id="theimage" src="http://www.google.com/logos/arthurboyd2010-hp.jpg" width="400">
</body>
</html>
