为什么这个 jquery 只对 html 中的第一个输入起作用？

//check answer on ENTER keyboard press
$("body").on("keypress", "input:text[name=guesslogo]", function(e){
    if (e.keyCode == 13) {  
        $(this).siblings(".check").trigger("click");
    }
});

html，在这个 html 示例中，它仅适用于最后一个：S

    <h2>Level: 1 - 3</h2>

我已经复制并测试了您的代码，它似乎在这里工作得很好：

http://jsfiddle.net/YeFVt/

$(document).on("keypress", "input:text[name=guesslogo]", function(e){
    console.log(e.keyCode);
    if (e.keyCode == 13) {  
        console.log('got here');
        $(this).siblings(".check").trigger("click");
    }
});

这可能与您的 .check 链接在您的实时代码中无法正常工作有关？

最后一个错误与<input>未关闭的标签有关。
