带有换行符的HTML中的JSON

Question

I have some Javascript on my page that makes an ajax call which returns some JSON data.

With the result I do this:

results = JSON.stringify(data, undefined, 2);
console.log(results);
$('.box').append(results);

.box is just an empty div.

console.log(results) gives me an indented result with linebreaks but the data in .box is just all in one line.

How can I make sure that the result in .box is also on multiple lines and indented?

Answer 1

.box is just an empty div.

Make it an empty <pre> instead:

<pre class="box"></pre>

Answer 2

I agree with using <pre> , but another option is to replace all \\n with <br> elements, and spaces with   . It's probably really unnecessary (since <pre> preserves the whitespace). You can try:

var data = {key1: "value1", key2: "value2", key3: {key4: "value4"}},
    results = JSON.stringify(data, undefined, 2),
    results2 = results.replace(/\n/g, "<br>").replace(/[ ]/g, "&nbsp;");
console.log(results);
$(".box").append(results2);
