我有一些类似这样的html:
<div id="1">
<p>
Volume = <input type="text" />
<button rel="3.93e-6" class="1" type="button">Check answer</button>
</p>
<div></div>
</div>
and some JS like this:
$("button").click(function () {
var buttonNo = $(this).attr('class');
var correct = Number($(this).attr('rel'));
validate (Number($("#"+buttonNo+" input").val()),correct);
$("#"+buttonNo+" div").html(feedback);
});
What I'd really like is if I didn't have to have the class="1" on the button (I know numeric classes aren't valid, but this is a WIP!), so I could determine buttonNo based on the id of the parent div. In real life there are multiple sections looking like this.
How do I find the id of the div parenting the button.
在按钮代码中存储答案的更具语义的方式是什么.我想让非程序员在不 destruct 东西的情况下进行复制和粘贴，尽可能做到万无一失！
