我将文本存储在一个包含多个 span 标签的变量中。
我想一次获取每个跨度内的所有内容。 我如何使用 jQuery 或 javascript 做到这一点？

更新:此解决方案已根据评论中的其他问题进行了更新:

只需获取父选择器的 .text() 属性即可。

var myWords = "<span>I</span><span> </span><span>like</span><span> </span><span>words.</span>";

/* "I like words" */
alert($(myWords).find("span").text());
alert($("p.words span").text());

<p class="words">
  <span>I</span><span> </span><span>like</span><span> </span><span>words.</span>
</p>
