Description Keishi Hattori 2012-05-02 01:56:35 PDT
I need this to implement the datalist UI for  <input type=email multiple>.
HTMLInputElement.value gives you the sanitized value so the whitespace between values are trimmed.
We need to append the selected suggestion to the end without modifying the rest of the text.

* You should add explanation what is these functions.  It's not clear.

* "innerTextValue" is not a good name for public API. It should be visibleValue, editingValue, userEditingValue, shownValue, etc.

* If possible, we should avoid to expose setInnerTextValue().  Can you set the value by editing commands and remove setInnerTextValue()?

Hmm. Using the "InsertText" command instantly reopens the autofill popup.  Calling hidePopup right after didn't hide it.

I'll see what I can do.

AutofillAgent was putting the textFieldDidChange event into a task queue.
I was able to work around it and achieve the original behavior by doing this. So I think I can remove setInnerTextValue.

void AutofillAgent::SetNodeText(const string16& value,
                                WebKit::WebInputElement* node) {
  string16 substring = value;
  substring = substring.substr(0, node->maxLength());

  WebKit::WebView* web_view = render_view()->GetWebView();
  if (!web_view || !web_view->focusedFrame())
    return;

  web_view->focusedFrame()->executeCommand(WebString::fromUTF8("selectAll"));
  web_view->focusedFrame()->executeCommand(WebString::fromUTF8("InsertText"), substring);
  weak_ptr_factory_.InvalidateWeakPtrs();
  MessageLoop::current()->PostTask(
                                   FROM_HERE,
                                   base::Bind(&AutofillAgent::DidSetNodeText,
                                              weak_ptr_factory_.GetWeakPtr()));
}

void AutofillAgent::DidSetNodeText() {
  WebKit::WebView* web_view = render_view()->GetWebView();
  if (web_view)
    web_view->hidePopups();
}

Done.

visibleValue is used in WebCore for something else so I went with editingValue.

Perhaps we should expose a method to append the selected suggestion, rather than exposing the internal details?

r- because of build errors.

What happens if setEditingValue() is called for non-textfield input types, or textfield without a renderer?

Yes the assertion fails. Fixed.

We had better mention the limitations of non-textfield types and renderer.

ok

nit: We prefer 4-space indentation.

> LayoutTests/fast/forms/editing-value.html:28
> +if (window.internals)
> +    internals.setEditingValue(input, " foo ");
> +shouldBe('input.value', '"foo"');

We had better show a message if window.internals is not available.

You should mention the caret position.
