Bug 71357 – Web Inspector: Cannot edit elements commented with <!--

• Component: Web Inspector (Deprecated)
• Status: RESOLVED FIXED

[Alexander Pavlov (apavlov)]

What steps will reproduce the problem?
1. Navigate to phrack.com/issues.html
2. Open developer tools 
3. Right click on super secret hidden Kiwicon endorsement


What is the expected result?

4. Get "Edit as HTML" option
5. Uncomment

What happens instead?

4. No option to edit, only Inspect Element and Word Wrap.

Please provide any additional information below. Attach a screenshot if
possible.

If I comment out any element in this fashion I cannot uncomment it via the dev tools, i have to reload the page.

I don't see why the dev tools can't edit commented elements. That doesnt make sense.

r- for two branches in setOuterHTML

> LayoutTests/inspector/elements/edit-dom-actions.html:165
> +        if (typeof dataNode === "string")

You should use different method for comment nodes.

> Source/WebCore/inspector/InspectorDOMAgent.cpp:772
> +        RefPtr<DocumentFragment> fragment = DocumentFragment::create(document);

You should use this branch for both cases.

> Source/WebCore/inspector/InspectorDOMAgent.cpp:776
> +            return;

Assign errorString here.

> Source/WebCore/inspector/InspectorDOMAgent.cpp:781
> +            return;

ditto

> Source/WebCore/inspector/InspectorDOMAgent.cpp:791
> +        if (ec)

ditto

> Source/WebCore/inspector/front-end/ElementsTreeOutline.js:1061
> +    _populateCommentContextMenu: function(contextMenu, commentNode)

You should call this method from _populateTagContextMenu (and call it _populateNodeContextMenu). Should also work for Text nodes.

If user passes TextNode id into this method, he will get an error message saying that it should always be id of the Element. But we do support nodes (see comment above). You should either support more node types and remove this assertion or not call getOuterHTML for non-Element nodes.

> Source/WebCore/inspector/InspectorDOMAgent.cpp:772
> +    if (document->isHTMLDocument())

You could put this check earlier. Can this happen at all?

> Source/WebCore/inspector/InspectorDOMAgent.cpp:787
> +        requiresTotalUpdate = htmlElement->tagName() == "HTML" || htmlElement->tagName() == "BODY" || htmlElement->tagName() == "HEAD";

no need to cast, tagName() is nodeName() for elements.
