    <p>Here's another variant, which also does some simple parsing in case you have <code>100g</code> as input, versus <code>100</code>. Also, the data structure gets reinitialized every time, so everything does not get doubled on every click.</p> <pre><code>$(".calculate").bind("click", function(e) { //get the correct parent of the button var parent = $(this).closest("#calc"); var ingredients = {}; var extractWeight = function (input) { // you can add other logic here // to parse stuff like "1kg" or "3mg" // this assumes that everything is // in grams and returns just the numeric // value return parseInt(input.substring(0, input.length - 1)); } //get relevant data parent.find(".options").each(function(index, element) { var opt1 = $(this).children(".opt1").children("input").val(); //weight var opt2 = $(this).children(".opt2").children("input").val(); //ingredient // initialize to 0 if not already initialized ingredients[opt2] = ingredients[opt2] ? ingredients[opt2] : 0; ingredients[opt2] += extractWeight(opt1); }); });​ </code></pre> <p>Here are some tips:</p> <ul> <li><code>{}</code> is called an object literal and is used to create a new empty object</li> <li>object members can be accessed dynamically through the <code>[]</code> notation (i.e. if <code>x === "name"</code> then <code>o[x] === o.name</code>)</li> <li>variables are visible inside functions that are at the same level or deeper in the scope - like in my example I use <code>ingredients</code> in the <code>each</code> function.</li> <li>arrays in JavaScript only support numeric keys, so you won't have stuff like PHP's "associative arrays". Objects fill this gap in JS.</li> </ul>

    1. COThank you for the help, harynar's answer was closest at helping me with my problem, but your explanation was also very helpful. Unfortunately I cannot mark two as Answers so I'll rate yours up and thank you instead :)

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).
