what is wrong with this jquery code

Hi I am using following code for applying multiple attributes of css through jquery. My code is

$("div:contains('Awais')").css( {text-decoration : 'underline', cursor : 'pointer'} );

I get javascript error

missing : after property i开发者_JAVA百科d
$("div:contains(John)").css( {text-dec...: 'underline', cursor : 'pointer'} ); 

But When I remoce text-decoration property the error vanishes. What is wrong with this code

text-decoration is an invalid property name unless it's enclosed in quotes as a string:

$("div:contains('Awais')").css( {'text-decoration' : 'underline', cursor : 'pointer'} );

Object properties must be enclosed in quotes unless they are valid Javascript identifiers. This is true for declarations in object literals and also for accessing using the dot notation (so object.text-decoration is invalid.

You can't use a hyphen unquoted in JavaScript, to modify text-decoration use textDecoration:

$("div:contains('Awais')").css( {textDecoration : 'underline', cursor : 'pointer'} );

Or quote it:

$("div:contains('Awais')").css( {'text-decoration' : 'underline', cursor : 'pointer'} );
