Asset.script ViewHelper `<f:asset.script>`¶

ViewHelper to add JavaScript to the TYPO3 AssetCollector. Either a file or inline JavaScript can be added.

Examples¶

<f:asset.script identifier="identifier123" src="EXT:my_ext/Resources/Public/JavaScript/foo.js" />
<f:asset.script identifier="identifier123">
   alert('hello world');
</f:asset.script>

Details¶

In the AssetCollector, the "identifier" attribute is used as a unique identifier. Thus, if assets are added multiple times using the same identifier, the asset will only be served once (the last added overrides previous assets).

Some available attributes are defaults but do not make sense for this ViewHelper. Relevant attributes specific for this ViewHelper are: async, crossorigin, defer, integrity, nomodule, nonce, referrerpolicy, src, type.
