    <p>I have a form with money value input fields, the values of which are added together on keyup event and the total inserted into another input field. this works fine.</p> <pre><code>&lt;table id="itemsqty"&gt;&lt;tr&gt;&lt;th style="min-width: 4em;"&gt;Qty&lt;/th&gt;&lt;th style="min-width: 10em;"&gt;Description&lt;/th&gt;&lt;th style="width: 4em;"&gt;Price&lt;/th&gt;&lt;/tr&gt; &lt;tr&gt;&lt;td&gt;&lt;select name="qty[]" id="qty0"&gt;&lt;option selected="selected"&gt;1&lt;/option&gt; &lt;option&gt;2&lt;/option&gt;&lt;option&gt;3&lt;/option&gt;&lt;option&gt;4&lt;/option&gt;&lt;option&gt;5&lt;/option&gt;&lt;/select&gt;&lt;/td&gt;&lt;td&gt; &lt;input placeholder="Enter item name in here" type="text" name="item[]" id="item0" /&gt;&lt;/td&gt; &lt;td&gt;&lt;input class="itemprice" placeholder="Total price for this item" type="text" name="itemprice[]" id="itemprice0" /&gt;&lt;/td&gt;&lt;/tr&gt; &lt;tr&gt;&lt;td&gt;&lt;select name="qty[]" id="qty1"&gt;&lt;option selected="selected"&gt;1&lt;/option&gt;&lt;option&gt;2&lt;/option&gt;&lt;option&gt;3&lt;/option&gt;&lt;option&gt;4&lt;/option&gt;&lt;option&gt;5&lt;/option&gt;&lt;/select&gt;&lt;/td&gt;&lt;td&gt;&lt;input placeholder="Enter item name in here" type="text" name="item[]" id="item1" /&gt;&lt;/td&gt;&lt;td&gt;&lt;input class="itemprice" placeholder="Total price for this item" type="text" name="itemprice[]" id="itemprice1" /&gt;&lt;/td&gt;&lt;/tr&gt; &lt;tr&gt;&lt;td&gt;&lt;select name="qty[]" id="qty2"&gt;&lt;option selected="selected"&gt;1&lt;/option&gt; &lt;option&gt;2&lt;/option&gt;&lt;option&gt;3&lt;/option&gt;&lt;option&gt;4&lt;/option&gt;&lt;option&gt;5&lt;/option&gt;&lt;/select&gt;&lt;/td&gt;&lt;td&gt; &lt;input placeholder="Enter item name in here" type="text" name="item[]" id="item2" /&gt;&lt;/td&gt;&lt;td&gt;&lt;input class="itemprice" placeholder="Total price for this item" type="text" name="itemprice[]" id="itemprice2" /&gt;&lt;/td&gt;&lt;/tr&gt; &lt;tr id="totalrow"&gt;&lt;td&gt;&lt;a href="javascript:;" id="addanotherlnk"&gt;Add another item&lt;/a&gt;&lt;/td&gt;&lt;td style="text-align: right;padding-right: 7px;float: right;"&gt;&lt;label for="gtotal" &gt;Total:&lt;/label&gt;&lt;/td&gt;&lt;td&gt;&lt;input readonly type="text" name="gtotal" id="gtotal" value="£0.00" /&gt;&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt; </code></pre> <p>The value of the total input field (#gtotal) is updated using this script, and it works fine:</p> <pre><code>$('.itemprice').live("keyup", function (event) { var t = 0; for (var ip=0; ip &lt;3; ip++){ a = $('#itemprice'+ip).val(); a = a.replace("£",""); //t = t + a; t = Number(t) + Number(a); } //then add all values $('#gtotal').val(''); var formattedMoney = '£' + t.formatMoney(2,',','.'); $('#gtotal').val(formattedMoney); }); </code></pre> <p>Users can then add new fields using a link which fires this script:</p> <pre><code>$('#addanotherlnk').click(function(){ //count number of items of same class var ic; ic = $('.itemprice').length; $('&lt;tr&gt;&lt;td&gt;&lt;select name="qty[]" id="qty'+ic+'"&gt;&lt;option selected="selected"&gt;1&lt;/option&gt;&lt;option&gt;2&lt;/option&gt;&lt;option&gt;3&lt;/option&gt;&lt;option&gt;4&lt;/option&gt;&lt;option&gt;5&lt;/option&gt;&lt;/select&gt;&lt;/td&gt;&lt;td&gt;&lt;input placeholder="Enter item name in here" type="text" name="item[]" id="item'+ic+'" /&gt;&lt;/td&gt;&lt;td&gt;&lt;input class="itemprice" placeholder="Total price for this item" type="text" name="itemprice[]" id="itemprice'+ic+'" /&gt;&lt;/tr&gt;').insertBefore('#totalrow'); }); </code></pre> <p>This works fine and adds a unique ID to the inputs/ However, the scripts which updates the totals does not seem to recognise this new input field. I know it is something to do with the fact that this is a dynamically added field, hence why I used jquery .live() method but this did not fix the problem. </p> <p>All help is very much appreciated.</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).
