| Post subject: | Eidogo's problem when keyboard support is enabled |
When turning on Eidogo's keyboard support, allowing web users to replay a game using keyboard (the arrow keys), there appears to be some bad side effect. I experienced this and had to disable keyboard support on go4go.net. For example, pressing '1' on keyboard actually plays the game forward (try this on any 19x19 posts containing a game records). This causes problem when the same web page contains a form (such as a comment box or a user login area) because one cannot input number '1' into these fields, at least on some variants of Linux systems I've tested. I wonder if anyone else experienced the same? Can anyone suggest a possible solution. I've done a little bit research on Google - this seems to have something to do with Javascript stealing focus in some situations. |

I'm on a 64-bit Debian box, and I haven't had this issue with either Firefox or Chrome. If I click on Eidogo, Eidogo will have focus and handles the input from my keyboard. If I click on a text field, the focus gets transferred to that. |

Not sure why, may have something to do with 19x19 displaying Eidogo player in an iframe. |

It also seems to work correctly on GoGameGuru. Maybe you could look into the similarities of how these two sites do it? |

These are about the two most popular Go sites. If they do not experience any problem, I should not either. In fact gogameguru also embeds Eidogo player in an iframe, as 19x19 does. Must be a good technical reason to do so. I will try the same idea. |

It turns out that putting Eidogo inside an iframe does fix the problem on go4go.net. When I examine things in detail, I found that the Eidogo player contains a number of example html files and one of which is called "example_iframe.html" containing a message in an textarea: Quote: You can type and use arrow keys in this box while still having keyboard shortcuts when the player above has focus. So I guess its author faced similar technical problems before. It is a pity these rather important details are not documented. Eidogo is no doubt a wonderful piece of technical work, but like many open-source projects it has little documentation. |
