Text input ignoring 0 as value

[dwp-dmitri-algazin]

Description of the issue

If 0 (zero) is a valid field value, govukInput() ignores it, because of this if condition:

govuk-frontend/packages/govuk-frontend/src/govuk/components/input/template.njk

Line 52 in 87d7633

{%- if params.value %} value="{{ params.value }}"{% endif %}

As we know from JavaScript, if ( 0 ) returns false, not true

Steps to reproduce the issue

Create govukInput with 0 value

Actual vs expected behaviour

I would expect to see mu input with value 0 in it

Environment (where applicable)

we use DWP Casa framework with latest GOV.UK Frontend Version: 5.0.0

• Operating system: any
• Browser: any
• Browser version: any
• GOV.UK Frontend Version: 5.0.0

when zero is a number ( 0 )

when zero is a string ( '0' )

Uh oh! @dwp-dmitri-algazin, the image you shared is missing helpful alt text. Check your issue body.

Alt text is an invisible description that helps screen readers describe images to blind or low-vision users. If you are using markdown to display images, add your alt text inside the brackets of the markdown image.
