我是一名新程序员,我对学习JavaScript非常感兴趣。我正在制作一个用户输入金额的输入框。我希望它保存到用户nextTime编辑/更新它,但我很难做到。我一直在互联网上寻找这样的一个月,但找不到我理解的东西。我知道一种使用Cookies的方法,但我真的不知道如何编写cookie,我只需要一些提示并帮助完成。 感谢。
HTML
<form id="update" onsubmit="return false" method="post">
<td><input class="rateContainer" value="Rate" disabled></td>
<td><input type="number" id="rate"></input></td>
<td><input type="submit" value ="Update" onclick="Update();" /></td>
</form>
JAVASCRIPT
function Update() {
var Update = document.getElementById("rate").submit;
}

不要使用cookies。使用sibling(X,Y) :-
mother(Out1,X),
father(Out2,X),
mother(Out1,Y),
father(Out2,Y).
