我之前已经这样做了。在这里尝试我的解决方案 http://jsfiddle.net/R8PhF/3/

I've already done that before. Try my solution here http://jsfiddle.net/R8PhF/3/

$(document).ready(function(){
    $('#mytextbox').keyup(function(e){
        var code = (e.keyCode ? e.keyCode : e.which);
        if(code == 13) {
            var tabables = $("*[tabindex != '-1']:visible");
            var index = tabables.index(this);
            tabables.eq(index + 1).focus();
        }        
    });
});​
