    <p>I am trying get paged json responses from Topsy (http://code.google.com/p/otterapi/) and am having problems merging the objects. I want to do this in browser as the api rate limit is per ip/user and to low to do things server side.</p> <p>Here is my code. Is there a better way? Of course there is because this doesn't work. I guess I want to get this working, but also to understand if there is a safer, and/or more efficient way.</p> <p>The error message I get is ...</p> <p>TypeError: Result of expression 'window.holdtweetslist.prototype' [undefined] is not an object.</p> <p>Thanks in advance.</p> <p>Cheers Stephen</p> <pre><code> $("#gettweets").live('click', function(event){ event.preventDefault(); getTweets('stephenbaugh'); }); function getTweets(name) { var MAX_TWEETS = 500; var TWEETSPERPAGE = 50; var BASE = 'http://otter.topsy.com/search.json?type=tweet&amp;perpage=' + TWEETSPERPAGE + '&amp;window=a&amp;nohidden=0&amp;q=@' + name + '&amp;page=1'; var currentpage = 1; alert(BASE); $.ajax({ dataType: "json", url: BASE, success: function(data) { window.responcesreceived = 1; var response=data.response; alert(response.total); window.totalweets = response.total; window.pagestoget = Math.ceil(window.totalweets/window.TWEETSPERPAGE); window.holdtweetslist = response.list; window.holdtweetslist.prototype.Merge = (function (ob) {var o = this;var i = 0;for (var z in ob) {if (ob.hasOwnProperty(z)) {o[z] = ob[z];}}return o;}); // alert(data); ;; gotTweets(data); var loopcounter = 1; do { currentpage = currentpage + 1; pausecomp(1500); var BASE = 'http://otter.topsy.com/search.json?type=tweet&amp;perpage=' + TWEETSPERPAGE + '&amp;window=a&amp;nohidden=0&amp;q=@' + name + '&amp;page=' + currentpage; alert(BASE); $.ajax({dataType: "json", url: BASE, success: gotTweets(data)}); } while (currentpage&lt;pagestoget); } }); }; function gotTweets(data) { window.responcesreceived = window.responcesreceived + 1; var response = data.response; alert(response.total); window.holdtweetslist.Merge(response.list); window.tweetsfound = window.tweetsfound + response.total; if (window.responcesreceived == window.pagestoget) { // sendforprocessingsendtweetlist(); alert(window.tweetsfound); } } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
