Mark Coleman's answer is certainly far better than the selected answer, but if you want to avoid the global variable for the timeout ID (the doit variable in Mark's answer), you could do one of the following:

(1) Use a an immediately invoked function expression (IIFE) to create a closure.

$(window).resize((function() { // This function is immediately invoked
                               // and returns the closure function.
    var timeoutId;
    return function() {
        clearTimeout(timeoutId);
        timeoutId = setTimeout(function() {
            timeoutId = null; // You could leave this line out.
            // Code to execute on resize goes here.
        }, 100);
    };
})());

(2) Use a property of the event handler function.

$(window).resize(function() {
    var thisFunction = arguments.callee;
    clearTimeout(thisFunction.timeoutId);
    thisFunction.timeoutId = setTimeout(function() {
        thisFunction.timeoutId = null; // You could leave this line out.
        // Code to execute on resize goes here.
    }, 100);
});
