Question

="" 上的自定义属性中获取数据请检查代码底部的javascript代码。我的目标是将所有data-cc属性值作为数组存储到名为“collection”的变量中。我已经做了下面的代码，但是我缺少的东西根本不起作用。提前致谢

Answer 1

使用.each()循环抛出图像并将值添加到数组

请参阅代码段

＆＃13;

var collection = [];
$('[data-cc]').each(function() {
  collection.push($(this).attr('data-cc'));
});

console.log(collection);

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<p id="fl">
  <img src="/images/flags/il.svg" data-cc="a" class="zastavica" />
  <img src="/images/flags/il.svg" data-cc="b" class="zastavica" />
  <img src="/images/flags/il.svg" data-cc="c" class="zastavica" />
