PURPOSE:
The Purpose of this component is to restrict the copy option from the user level of apex
page.
SCENARIO :
1.Consider in our apex application we are providing any confidential message or data
that should not be copied by user level,we can restrict by this component.
2.If we want to provide any notification message for restrict the copy option for that
particular confidential page, we can use this component.
STEPS TO DO:
1.Create a page in apex and use the region to display some text that to restrict copy option
2.In that region source type the script that given below and save the page and run it.
SCRIPT EXPLANATION:
We can restrict the copy option by these ways,
1.Restrict Ctrl+C Button.
2.Restrict Mouse Right click .
This script will restrict these two ways,
//Restrict Ctrl+C Button in javascript
<head>
<script language="javascript">
<!--
function Disable_Control_C() {
var keystroke = String.fromCharCode(event.keyCode).toLowerCase();
if (event.ctrlKey && keystroke == 'c') {
event.returnValue = false;
alert('You can not copy here'); }
}
</script>
</head>
//This script will restrict the CTRL+C and stop the action in user level
<body onkeydown="javascript:Disable_Control_C()"> </body>
</html>
//Disable right mouse click Script for IE(Internet Explorer)
<script language=JavaScript>
var message = "Mouse Right Click Disabled!";
function clickIE4() {
if (event.button == 2) {
alert(message);
return false;
}
}
//Disable right mouse click Script for another browser
function clickNS4(e) {
if (document.layers || document.getElementById && !document.all) {
if (e.which == 2 || e.which == 3) {
alert(message);
return false;
}
}
}
//Here we are restrict the mouse event and mouse down event
if (document.layers) {
document.captureEvents(Event.MOUSEDOWN);
document.onmousedown = clickNS4;
} else if (
document.all && !document.getElementById) {
document.onmousedown = clickIE4;
}
document.oncontextmenu = new Function("alert(message);return false")
</script>
3.We can execute this query anywhere in the region source or in the HTML attribute
4.Here I have provide some screen-shots that will helpful for your reference.
SCREENSHOT
1.If the user try to copy the page using CTRL+C,then automatically user will get this
notification.
2.If the user try to copy by mouse then, user will get this notification that “Mouse Right
Click Disabled”.
