What's the right way to decode a string that has special HTML entities in it? [duplicate] 7 answers

解码其中包含特殊HTML实体的字符串的正确方法是什么? [重复] 7个答案

Consider this for example:

考虑这个例子:

<div>
  A&
  <br>
  B
</div>

If I use $('div').html(), it returns A&<br>B. It converts A& into A& which I do not want.

如果我使用$('div')。html(),则返回A&
B.它将A&转换为A&这是我不想要的。

If use use $('div').text(), it returns A&B. It ignores the <br> which I do not want either.

如果使用$('div')。text(),则返回A和B.它忽略了我不想要的那个。

I'm looking for a way to get all the html inside the div without parsing it and without skipping over the tags like <br> either.

我正在寻找一种方法来获取div中的所有html而不解析它,也没有跳过像
这样的标签。

This is the result I want: A&<br>B. How do I achieve that?

这是我想要的结果:A&
B.我如何实现这一目标?

function decodeEntities(encodedString) {
    var textArea = document.createElement('textarea');
    textArea.innerHTML = encodedString;
    return textArea.value;
}
console.log(decodeEntities($('div').first().html()))

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div>
  A&
  <br>
  B
</div>

This is really a "hack" but it does work.

这真的是一个“黑客”,但确实有效。

$("<textarea>").html($("div").html()).val()
