Body
I am using jQuery 1.7.1 (but that's probably irrelevant). I have several JavaScript arrays that are populated in several ways. The arrays, basically, look like this: <pre><code>var TreeArray = [0,1,2]; var FruitArray = [4,5,6,7]; </code></pre> I have some links that have an item type and an item id: <pre><code><a href='?' class='Link' data-itemid='123' data-itemtype='Tree'>elm</a> <a href='?' class='Link' data-itemid='789' data-itemtype='Tree'>walnut</a> <a href='?' class='Link' data-itemid='456' data-itemtype='Fruit'>orange</a> <a href='?' class='Link' data-itemid='111' data-itemtype='Fruit'>apple</a> </code></pre> When the link is clicked, the ItemType and ItemID are collected and passed to the addToArray() function: <pre><code>$Links.click(function(e) { e.preventDefault(); var ItemType = $(this).data("itemtype"); var ItemID = $(this).data("itemid"); addToArray(ItemType, ItemID); }); </code></pre> Here's where the problem is. If the ItemType is "Tree", I want to put the ItemID in the TreeArray. If the ItemType is "Fruit", I want to put the ItemID in the FruitArray. Here's my function (that doesn't work): <pre><code>var addToArray = function addToArray(ItemType, ItemID) { var WhichArray = ItemType + "Array"; WhichArray.push[ItemID]; } </code></pre> I will have quite a few different types of arrays, not just two. I will have quite a few functions. So, how can I access these arrays dynamically?

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.
