Java脚本

$("input").bind("keydown", function(event) {
    if (event.which === 13) {
        event.stopPropagation();
        event.preventDefault();
        $(this).nextAll("input").eq(0).focus();
    }
});

我已经更新了这个小提琴

有了这个

小提琴

http://jsfiddle.net/mparvez1986/L8Ax7/

但更新的小提琴无法正常工作，请帮助

未定义

这是因为.nextAll()仅选择下一个兄弟姐妹，而在您的第一个小提琴中输入的是兄弟姐妹，而在第二个小提琴中则没有。在您的情况下，更好的选择是使用.index()方法：

var $inputs = $("input").on("keydown", function(event) {
    if (event.which === 13) {
        event.stopPropagation();
        event.preventDefault();
        // `i` is the index of the current element 
        // in the cached jQuery collection
        var i = $inputs.index(this);
        $inputs.eq(i+1).focus();
    }
});
