JSON in HTML with line breaks
提问by Oskar Persson
I have some Javascript on my page that makes an ajax call which returns some JSON data.
我的页面上有一些 Javascript 可以进行 ajax 调用,返回一些 JSON 数据。
With the result I do this:
结果我这样做:
results = JSON.stringify(data, undefined, 2);
console.log(results);
$('.box').append(results);
.boxis just an empty div.
.box只是一个空的div。
console.log(results)gives me an indented result with linebreaks but the data in .boxis just all in one line.
console.log(results)给我一个带有换行符的缩进结果,但数据.box只是在一行中。
How can I make sure that the result in .boxis also on multiple lines and indented?
我怎样才能确保结果.box也在多行上并缩进?

.box is just an empty div.
.box 只是一个空的 div。
Make it an empty <pre>instead:
<pre>改为空:
<pre class="box"></pre>
回答by Ian
I agree with using <pre>, but another optionis to replace all \nwith <br>elements, and spaces with . It's probably really unnecessary (since <pre>preserves the whitespace). You can try:
我同意使用<pre>,但另一种选择是\n用<br>元素替换 all ,用 . 这可能真的没有必要(因为<pre>保留了空格)。你可以试试:
var data = {key1: "value1", key2: "value2", key3: {key4: "value4"}},
results = JSON.stringify(data, undefined, 2),
results2 = results.replace(/\n/g, "<br>").replace(/[ ]/g, " ");
console.log(results);
$(".box").append(results2);
