将\\ n替换为 <br> 不管用

Question

In my mongoDB:

description: "Test\n\nTest"

When I try to show it in my ejs file the text ignores de "\\n"

Test Test

My HTML

<div id="description">
    <%= test.description %>
</div>

I tried to fix this using this code :

var desc = $('#description').text();
desc.replace("\n", "<br>");

$('.description').text(desc);

Also tried:

desc.replace(/(?:\r\n|\r|\n)/g, '<br />');

and:

desc.split("\n").join("<br />");

None of this worked

If I print var desc = $('#description').text(); in the Chrome console, it shows this:

              Test

Test

What I'm doing wrong and how do i fix this?

Answer 1

Use html() instead of text() as you want to change the HTML markup.... text() will ignore the <br> tags

Also you are just replacing the value not updating it.....need to put the replaced value in the desc variable by

desc = desc.replace(/\n/g, "<br>");

Also desc.replace("\\n", "<br>"); will just replace the first \\n match

Stack Snippet

 var desc = "Test\\n\\nTest" desc = desc.replace(/\\n/g, "<br>"); $('#description').html(desc);

Answer 2

Using your code, desc.split("\\n").join("<br />"); works fine for me.

 var desc = $('#description').text(); console.log("original text = " + desc); desc = desc.split("\\n").join("<br />"); console.log("using split/join = " + desc);
