    <p>I've written a plugin for jQuery, and I used the boilerplate pattern of <a href="http://jqueryboilerplate.com/" rel="nofollow">http://jqueryboilerplate.com/</a></p> <p>Inside, i have the following snippet of code:</p> <pre><code>ShoppingcartPlugin.prototype = { bindButtons : function(){ var self = this; $('.addtocart').on('click.shoppingCart', function(event){ event.preventDefault(); $('.product-size-wrong').addClass('hidden'); $('.product-added').addClass('hidden'); if(!self.validateForm()) return; self.updateProductDataInDOM(event); var b = self.addProduct(event); if(b){ self.addExtraProducts(event); //aanvullingen self.updatePrices(); self.calculateWeight(); self.calculateDeposit(); $('.product-added').removeClass('hidden'); } self.persist(); }); $("body").on("click.shoppingCart","a.removefromcart", function(event){ self.logger("a.removefromcart clicked"); event.preventDefault(); self.removeProduct(event); self.updateCartTotalPrice(); self.updatePrices(); self.calculateWeight(); self.calculateDeposit(); event.stopPropagation(); }); } } </code></pre> <p>Now, I've written a Jasmine testcase, that should simulate a click on a 'a.removefromcart' element. After that, I can spy on some Ajax call and see if the results are correct.</p> <p>So I've done this:</p> <pre><code>describe('Removing products testsuite', function(){ it('Should yield an empty cart, when the X is clicked in a cart with a single product', function(){ $('#shoppingcart').shoppingCart(); allProducts = {}; $('.addtocart').click(); //simulate click, and adding a product expect($.ajax.calls[1].args[0].data.shoppingCart[0].quantity).toBe(1); expect($.ajax.calls[1].args[0].data.shoppingCart.length).toBe(1); $('body').trigger('click.shoppingCart','a.removefromcart'); console.log($.ajax.calls); expect($.ajax.calls[2].args[0].data.shoppingCart.length).toBe(0); }); }); </code></pre> <p>the first simulation of a click works (for adding a product), but the removal doesn't get triggered, ie, the callback of the 'on' is never being called. </p> <p>The implementation works, but I 'd love to have a few testcases around this part of the plugin.</p> <p>Am I taking the right approach? Any suggestions how I could debug this, such that the .on callback gets fired?</p> <p>Edit: i should note that I used the $('a.removefromcart').on('click.shoppingCart', function(){...}); , but that has some other side-effects that I don't like, so I'd prefer to keep the click binding the same as it is now. I just want to trigger it programmatically.</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.
