jQuery.inArray returns the first index that matches the item you searched for or -1 if it is not found:

if($.inArray(valueToMatch, theArray) > -1) alert("it's in there");

theArray.splice(startRemovingAtThisIndex, numberOfItemsToRemove);

Or, you can perform a "remove" using the jQuery.grep util:

var valueToRemove = 'someval';
theArray = $.grep(theArray, function(val) { return val != valueToRemove; });
