Disable/enable an input with jQuery? $input.disabled = true; or $input.disabled = "disabled"; Which is the standard way? And, conversely, how do you enable a disabled input? Answer: jQuery 1.6+ To change the disabled property you should use the .prop() function. $("input").prop('disabled', true); $("input").prop('disabled', false); jQuery 1.5 and below The .prop() function doesn't exist, but .attr() does similar: Set the disabled attribute. $("input").attr('disabled','disabled'); To enable again, the proper method is to use .removeAttr() $("input").removeAttr('disabled'); In any version of jQuery You can always rely on the actual DOM object and is probably a little faster

How can I refresh a page with jQuery? How can I refresh a page with jQuery? Answer: Use location.reload(): $('#something').click(function() { location.reload(); }); The reload() function takes an optional parameter that can be set to true to force a reload from the server rather than the cache.
