Re: [YouTube-API] Re: strange search result

Hi Jeff, I invoke a search with the searchClicked function declaring showMyVideos as the callback function. We'vebeen using this technique for a while and it works robustly. It was only this morning that the search criteria I described caused the error. Its strange that an extra character in the search term can cause the error. I've tested many combinations of search terms to try to recreate so it must be rare but be good to get to the bottom of it.

My code is based on a code sample from youtube API from some time ago. Maybe I should be using a more up to date technique?

Cheers

Will

function searchClicked(e) { var q = $('#searchText').val(); //create a JavaScript element that returns our JSON data. var script = document.createElement('script'); script.setAttribute('id', 'jsonScript'); script.setAttribute('type', 'text/javascript'); script.setAttribute('src', 'http://gdata.youtube.com/feeds/' + 'videos?q='+q+'&start-index='+pageIndex+'&max-results=50&' + 'alt=json-in-script&callback=showMyVideos&' + 'orderby=relevance&sortorder=descending&format=5'); //attach script to current page - this will submit asynchronous //search request, and when the results come back callback //function showMyVideos(data) is called and the results passed to it $("body").append(script); } function showMyVideos(data) { var feed = data.feed; var entries = feed.entry || []; videoResults=[]; for (var i = 0; i < entries.length; i++) { var entry = entries[i]; var obj = new Object(); obj.ytID=ytID;

obj.playCount=entry.yt$statistics.viewCount.valueOf();

Uncaught TypeError: Cannot read property 'viewCount' of undefined

obj.thumb=entry.media$group.media$thumbnail[0].url;

obj.author=entry.author[0].name.$t;

obj.duration=entry.media$group.media$content[0].duration;

obj.description=replaceSpecialChars(entry.media$group.media$description.$t);

obj.title=replaceSpecialChars(entry.title.$t);

obj.ytLink=entry.link[0].href;

obj.cat = entry.category[1].label;

videoResults.push(obj);

}

//create instance of master view

directory = new VideoDirectoryView();

}

Hello,

 I can't reproduce what you're seeing. I also don't know what you mean
when you're talking about the viewCount property, as that's an
attribute associated with an individual video, not a search results
feed.

 Could you provide an example of the specific response values that are
causing problems?
