    <p>I am new to jQuery and so don't mind this question if it sounds stupid but here is something that I am trying to do :</p> <p>I have 3 functions like:</p> <pre><code>AddToCart Function which adds item to the shopping cart: //offer_id is the offer which we are trying to add to cart. addToCart: function(offer_id) { }, RemoveFromCart which removes data from the cart //target is link clicked and event is the click event. removeFromCart: function(target, event) { }, Get the current state of the cart //return string which represents current state of cart. getCartItems: function() { } </code></pre> <p>Now I am trying to do 3 things:</p> <ol> <li>if there is no <code>content</code> in cart and <code>addToCart</code> is called than <code>some action</code>, so basically here we need to check the current state of cart and that is obtained by calling <code>getCartItems</code> and if it is <code>Null</code> and than if <code>addToCart</code> is called than we perform <code>some action</code></li> <li>if there is <code>content</code> in the cart and <code>addToCart</code> is called than <code>some action</code>,so basically here we need to check the current state of cart and that is obtained by calling <code>getCartItems</code> and check if it is <code>Null</code> or not and than if <code>addToCart</code> is called than we perform <code>some action</code> if we had some content in the cart. </li> <li>if there is <code>content</code> in the cart and <code>removeFromCart</code> is called <code>some action</code>, so basically here we need to check the current state of cart and that is obtained by calling <code>getCartItems</code> and if it is not Null and if <code>removeFromCart</code> is called than we perform <code>some action</code></li> </ol> <p>Pseudocode of what I am trying to do: </p> <pre><code> if there is no content in cart and addToCart is called than $(document).track( ); if there is content in the cart and addToCart is called than $(document).track( ); if there is content in the cart and removeFromCart is called $(document).track( ); </code></pre> <p>My basic concern is that am complete newbie to jQuery and JavaScript and so am not sure how can I implement if...else logic and how can I call a function using jQuery/JavaScript. </p>

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).
