I have to implement a javascript function which would mask the content of a textbox (just as in a password field) when the cursor is
outside of the textbox but display the content when the cursor is within the textbox.
Any pointer to where such problem is solved or approach to implement this would be greatly appreciated.

Is there any forum / community which is popular and entirely devoted to javascript?

Thanks in advance.

You can easily change the type of your input field with the onfocus and onblur events. So when the text field is focused, you set its type to 'text' and when the focus is lost (onblur) you can set its type to 'password' using javascript...

(That wouldn't actually do what the OP wants, though; you'd have to look at mouse in/out events.)

And Internet Explorer, always the life of the party, can be finicky about changing the type of an input element.

What might work better is to have two elements, one a text field, one a password field, whose visibility is toggled.

Seems like a really weird requirement though...

I actually see this feature on a lot of wireless router config and WEP auth. I believe even OSX has a "show characters" button that lets you unmask the password field with typing in your wireless access password.

Well with non IE browsers, you can swap the type. With IE browsers you either needs to use a hidden field and swap/replace the text in the textbox OR you have to create and remove elements OR you need to show hide elements [password and plain textbox].

Thanks everyone for the inputs.


I did something like below and it works:

<html>

<head>
<scrfieldt type="text/javascrfieldt">
var globalvariable;

function onBodyLoad()
{

globalvariable = document.getElementById('test').cloneNode(true);

}

function UnMask(field){

var NewField=globalvariable.cloneNode(true);

if( field.type == 'password')
{
NewField.type = 'text';
NewField.value = field.value;
field.parentNode.replaceChild(NewField,field);

}

}

function Mask(field){


var NewField=globalvariable.cloneNode(true);

if(NewField.type == 'text')
{

NewField.type='password';
NewField.value = field.value;

field.parentNode.replaceChild(NewField,field);

}


}

</scrfieldt>
</head>

<body onLoad="onBodyLoad()">


<input id="test" type="text" onBlur = "Mask(this);" onFocus = "Unmask(this);" >
<input id="test1" type="text" >
</body>
</html>
