@name Text attribute not binding
@description
This diagnostic ensures that attributes which have the "special" Angular binding prefix (attr., style., and
class.) are interpreted as bindings. For example, <div attr.id="my-id"></div> will not
interpret this as an attribute binding to id but rather just a regular attribute and will appear
as-is in the final HTML (<div attr.id="my-id"></div>). This is likely not the intent of the developer.
Instead, the intent is likely to have the id be set to 'my-id' (<div id="my-id"></div>).
What should I do instead?
When binding to attr., class., or style., ensure you use the Angular template binding syntax.
<div [attr.id]="my-id"></div> <div [style.color]="red"></div> <div [class.blue]="true"></div>
What if I can't avoid this?
This diagnostic can be disabled by editing the project's tsconfig.json file:
{ "angularCompilerOptions": { "extendedDiagnostics": { "checks": { "textAttributeNotBinding": "suppress" } } } }
See extended diagnostic configuration for more info.
