Generating fresh line with knockout effect

Currently in the process of developing a Single Page Application (SPA). Utilizing knockout and observable array to iterate through a json array. Encountering an issue where there are br tags present within the text, but when using data-bind="text: myVar" I am unable to get the line breaks to work as expected. Instead of a new line, all I see is <br /> displayed in the text. My main question is how can I make knockout's data-bind function create new lines using these br tags from the json data? I attempted to use "white-space: pre-wrap", but unfortunately it did not resolve the issue.

Answer №1

To properly display line breaks, make sure to bind using html: instead of text:.

Check out the code snippet below:

var dataModel = {
  content: ko.observable('First Line <br />Second Line <br />Third Line')
};

ko.applyBindings(dataModel);
* {
  font-family: Arial;
  }
<script src="https://cdnjs.cloudflare.com/ajax/libs/knockout/3.2.0/knockout-min.js"></script>
<h2>Text Binding:</h2>
<span data-bind="text: content"></span>
<h2>HTML Binding:</h2>
<span data-bind="html: content"></span>
