Some jQuery methods don't their check private variables.

When faced with no arguments, most methods error out with no problems or return a value. But...

Each of the following method calls, starting with css, will return an error and stop the rest of the script.

$(document.body).css().each().filter().map().ready();
$(document.body).text('Test Completed.');

jQuery Error - no arguments with methods

Change History (4)

What is the suggested behavior for these cases?

jQuery should just return the jquery object to fail safe.

if( !arguments.length ){ return this; }

component:	unfiled → core

The cases are all incorrect uses of the methods per the documentation and api.
