    <p>One approach, which avoids iterating over an array, would be: </p> <pre><code>function getCookie(name) { var value = "; " + document.cookie; var parts = value.split("; " + name + "="); if (parts.length == 2) return parts.pop().split(";").shift(); } </code></pre> <p><strong>Walkthrough</strong></p> <p>Splitting a string by token will produce either, an array with one string (same value), in case token does not exist in a string, or an array with two strings , in case token is found in a string . </p> <p>The first (left) element is string of what was before the token, and the second one (right) is what is string of what was after the token.</p> <p>(NOTE: in case string starts with a token, first element is an empty string)</p> <p>Considering that cookies are stored as follows:</p> <pre><code>"{name}={value}; {name}={value}; ..." </code></pre> <p>in order to retrieve specific cookie value, we just need to get string that is after "; {name}=" and before next ";". Before we do any processing, we prepend the cookies string with "; ", so that every cookie name, including the first one, is enclosed with "; " and "=":</p> <pre><code>"; {name}={value}; {name}={value}; ..." </code></pre> <p>Now, we can first split by "; {name}=", and if token is found in a cookie string (i.e. we have two elements), we will end up with second element being a string that begins with our cookie value. Then we pull that out from an array (i.e. pop), and repeat the same process, but now with ";" as a token, but this time pulling out the left string (i.e. shift) to get the actual token value.</p>

    1. CO@user3132564 tried to edit this in, but its actually a comment: This method returns the wrong value when you search for a suffix of a cookie - if the value of document.cookie is "FirstName=John" and you call getCookie("Name"), you'll get back "John" even though there's no cookie by that name. It also doesn't work if one cookie's name is the suffix of another - if document.cookie is "Name=John; LastName=Doe", calling split("Name=") returns an array with three strings and the method doesn't return the right value for getCookie("Name").

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.
