Bug 190275 – Web Inspector: use iframe's name attribute for FrameTreeElement

• Component: Web Inspector
• Status: RESOLVED FIXED

[Devin Rousso]

Some iframe use the `srcdoc` attribute to set their content instead of a URL.  As a result, the main resource has no "real" URL, meaning we are unable to show anything meaningful.  For those cases (and those that have a `name` regardless), we should show the `name` somewhere in the `FrameTreeElement`s text.

I like the idea of this. Seems we could have a test for this. Do you have a screenshot of a before/after with this as well?

Is this.resource.parentFrame guaranteed to not be null?

It should always be valid.  `WI.Frame.prototype.initialize` sets the `_parentFrame`, and `this.resource` is equal to the `WI.Frame.prototype.mainResource`.  Additionally, every resource that get's added to a frame has it's `_parentFrame` set as well.

[Image] After Patch is applied

Any `WI.TreeElement` that follows a "%s (%s)" pattern is affected by this patch, where the first "%s" is the `name` of the `WI.Frame` and the second is the previously shown `url`.

I think the underscore is unnecessary. I think of underscore'd things as properties, not as getters, so this messes with my brain a bit.

You may want to move the Execution Context Picker in the Quick Console to this kind of formatting so we are consistent.
