I have two fields, one is emailid and another is password in my form. I want to prevent the user from pasting into those fields. They should be forced to enter manually, like Google Forms.
You could disable ctrl+v combination and right click as well.
for IE, you may tap into following event handlers:
onpaste=return false;
oncut=return false;
oncontextmenu=return false;
oncopy=return false;.
Here is a workaround for all browsers:
function noCTRL(e) {
var code = (document.all) ? event.keyCode : e.which;
var ctrl = (document.all) ? event.ctrlKey : e.modifiers & Event.CONTROL_MASK;
var msg = Sorry, this functionality is disabled.;
if (document.all) {
if (ctrl && code == 86) {
//CTRL+V
alert(msg);
window.event.returnValue = false;
} else if (ctrl && code == 67) {
//CTRL+C (Copy)
alert(msg);
window.event.returnValue = false;
}
} else {
if (ctrl == 2) {
//CTRL key
alert(msg);
return false;
}
}
}
In HTML section, your fields would look like:
Email :<input name=email type=text value=/><br/>
Password :<input name=password type=password value=/><br/>
Confirm Email :<input name=email type=text value= onkeydown=return noCTRL(event)/>
Confirm Password :<input name=password type=password value= onkeydown=return noCTRL(event)/>
I don't think user can copy password fields if input type is password
Hope this helps.
Note:
