    <p>I'm thinking about how to change a content of a div dynamically. So, here is the ajax request:</p> <pre><code>$.ajax({ url:'/foos', cache: false, type: 'get', }).done( function( foo_array ) { for( foo in foo_array ) { $('#foo-container').append('&lt;div class="foo-var"&gt;'+foo+'&lt;/div&gt;'); } }); </code></pre> <p>So bassically, this ajax append all foo-var divs from the server, but if the foo_array is too long or a big very big array there is a problem because i think that takes more and more time depending on the foo_array's length</p> <p>How can I append one by one??, how can I query one by one and append in foo-container instead query all foos and make an iteration??</p> <p>I want to do something like this</p> <pre><code>if(foos.hasNext()){ $.ajax..... append(foo)....} </code></pre> <p>foos is an array made by many documents from a mongodb database, so I cant get the length of the array because depends of the query's find() arguments..</p> <p>I'm using nodejs, mongodb, expressjs and jquery for ajax</p> <p>Sorry for my bad English, and thank you all!</p> <p>EDIT 2</p> <p>this is an example of the data in mongodb</p> <pre><code>{category:1, name:'robert',personal:true,option:'class'} {category:1, name:'alfredo',personal:false,option:'class'} {category:4, name:'ricardo',personal:true,option:'class'} {category:1, name:'genaro',personal:true,option:'class'} {category:2, name:'andres',personal:false,option:'class'} {category:1, name:'jose',personal:true,option:'class'} db.collection.find({personal:true}) // gives me 4 documents db.collection.find({option:'class'}) // gives me 6 documents db.collection.find({category:4}) // gives me 1 document </code></pre> <p>i dont know how many documents can get from the cursor, i need to charge one by one cause there are 5097841 documents in the databse so, ajax can take long time to return all the information, i need to query one by one if hasNext() in the cursor of mongodb</p>

    1. COI would suggest some kind of paging, where you load 10-15 items per request

    3. COif `foo_array` is truly an array you don't want to use `for/in`. Show sample of data. Comment regarding paging can also be done by multiple AJAX requests `$.each` is easy to implement http://api.jquery.com/each/

Guidance
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.
