Image width renditions breaks when using Vue.js

[herbergt]

The image width renditions functionality of the image core component breaks when using with Vue.js

The error says as follows

Uncaught TypeError: Cannot read property 'removeAttribute' of null
    at unwrapNoScript (clientlib-base.js:1877)
    at init (clientlib-base.js:1797)
    at new Image (clientlib-base.js:2000)
    at HTMLDocument.onDocumentReady (clientlib-base.js:2007)

The error happens right here.

The div with the id app is being used as the Vue main template. This Vue template encompass the whole page body of the page core component.

<div data-sly-attribute.id="app" data-sly-use.templatedContainer="com.day.cq.wcm.foundation.TemplatedContainer"
         data-sly-repeat.child="${templatedContainer.structureResources}"
         data-sly-resource="${child.path @ resourceType=child.resourceType, decorationTagName='div'}"></div>

Tracing down the problem I found that the Vue.js is changing the HTML of the nonscript tag generated by the image core component, stripping off the white spaces that the component generates. When the clientlib of the image core component tries to get the generated tag image, it uses the textContent of the element as follows that._elements.noscript.textContent.trim() , but it retrieves and empty text instead of the text with the image tag, because Vue had previously removed the white spaces. This causes the clientlib to break here.

Here the link to reproduce the issue.

Any workaround to solve this?

Hi

One option you can try is to override the imageimpl for v2 and see the required items are non null.

Another option might be to check the behavior for the later image v3 core component.

Thanks
