    <p>I have read through some of the suggested questions but I am not sure exactly how to implement them:</p> <ul> <li><a href="https://stackoverflow.com/questions/2101259/jquery-js-get-text-from-field-on-keyup-but-with-delay-for-further-typing">(jquery/js) - get text from field on keyup, but with delay for further typing</a></li> <li><a href="https://stackoverflow.com/questions/1909441/jquery-keyup-delay">How to delay the .keyup() handler until the user stops typing?</a></li> <li><a href="https://stackoverflow.com/questions/1620602/javascript-jquery-make-an-ajax-request-when-a-user-is-typing-in-a-textarea">How to trigger an onkeyup event that&#39;s delayed until a user pauses their typing?</a></li> </ul> <p>I have 8 textboxes, 7 are used for numeric input and the 8th is a total. i.e. 7.5 + 7.5 + 7.5 + 7.5 + 7.5 + 0.0 + 0.0 = 37.5</p> <p>I have the jQuery working so that it monitors each textboxes keyup() and adds all of the values and calculates the total.</p> <p>I decided that I want to format the users input in the 7 textboxes so that it comes out like #.# if they enter "1" or ".1" i.e. "1.0" or "0.1".</p> <p>The problem is that I need to add a delay before the input is formatted and I am unsure as to how I do it with javascript and/or jquery.</p> <pre><code> &lt;script type="text/javascript"&gt;

    1. COOn a completely unrelated note. I would recommend DRYing out your code. You do the exact same thing 7 times, and in that process, you do another thing 7 times each.

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
