我正在尝试默认使用HTML设置单选按钮。在浏览器中我有:
<label><input type="radio" checked="checked" name="optradio" i="1">Nein</label>
但未选中单选按钮。
我做错了什么?

My bad. I had another radio button later on the page that was also checked and had the same name="optradio". It would uncheck the first no matter where it is ~~:-|
$(function() {
$("div").html( `
<div class="radio radio1">
<label><input type="radio" checked="checked" name="optradio" i="1">Nein</label>
</div>
<div class="radio radio3">
<label><input type="radio" checked="checked" name="optradio" i="3">2</label>
</div>
` )
;
})

我们也可以使用单一检查而不是使用checked =“checked”。
