Comparison between bo-html and bo-text

As I was going through the documentation for the bindonce directive, a question popped into my head regarding the distinction between bo-html and bo-text.

  • bo-html:

This evaluates "markup" and displays it as HTML within the element.

  • bo-text:

This evaluates "text" and outputs it as plain text inside the element.

Therefore, I assumed that this code would function properly:

<span bo-html="<strong>SomeText</strong>"></span>

However, what I received was an error message:

Error: [$parse:syntax] Syntax Error: Token '<' not a primary expression at column 1 of the expression

Isn't <strong> just basic markup?

If this approach doesn't work (possibly due to a syntax issue...), could someone clarify the actual difference between bo-text and bo-html?

Answer №1

If you are looking to insert a string into bo-html, make sure to define it as a string since it requires a variable input.

<span bo-html="'<strong>SomeText</strong>'"></span>

Alternatively:

$scope.myVariable = '<strong>SomeText</strong>';
<span bo-html="myVariable"></span>

The difference lies in how you specify the content. Here's an example to illustrate:

$scope.myVariable = '<strong>SomeText</strong>';
<span bo-html="myVariable"></span> // Outputs <strong>SomeText</strong> as HTML
<span bo-text="myVariable"></span> // Outputs <strong>SomeText</strong> as text
