    <p>How can I get the value of the closest textbox and assign it into a variable? Then after getting the value, change the current value of that textbox by multiplying it by the value of previous textbox. I have three instances of divs with the same input elements so I think .closest() or .next() can help me. Here is a snippet of my code</p> <p>HTML</p> <pre><code>&lt;div class="box"&gt; &lt;b&gt;1&lt;/b&gt; &lt;input type="text" name="quantity" value="1"/&gt; &lt;input type="checkbox" name="ignoreThisCheckbox" checked="checked"/&gt; &lt;input type="text" name="price" value="10"/&gt; &lt;/div&gt; &lt;div class="box"&gt; &lt;b&gt;2&lt;/b&gt; &lt;input type="text" name="quantity" value="1"/&gt; &lt;input type="checkbox" name="ignoreThisCheckbox" checked="checked"/&gt; &lt;input type="text" name="price" value="10"/&gt; &lt;/div&gt; &lt;div class="box"&gt; &lt;b&gt;3&lt;/b&gt; &lt;input type="text" name="quantity" value="1"/&gt; &lt;input type="checkbox" name="ignoreThisCheckbox" checked="checked"/&gt; &lt;input type="text" name="price" value="10"/&gt; &lt;/div&gt; </code></pre> <p>JS</p> <pre><code>$("input[name=quantity]").each(function(){ $(this).bind("change keyup", function(){ var q = $(this).val(); var p = parseFloat($(this).closest("input[name=price]").val()).toFixed(2); var amount = q * p; $(this).closest("input[name=price]").val(amount) console.log(amount); }) }) </code></pre> <p>non working demo</p> <p><a href="http://jsfiddle.net/c6yfS/" rel="nofollow">http://jsfiddle.net/c6yfS/</a></p> <p>Thank you for responses</p> <p><strong>/* NOTE */</strong></p> <p>The purpose of the checkbox is just to show that I have a checkbox in between the two elements concerned.</p>

    1. COThe .closest() method begins its search with the element itself before progressing up the DOM tree. To get the value of other element you might need to use .next() or .prev(). You can also try this but I am not sure `var p = parseFloat($(this).closest("input[name=price]").closest("input[name=price]").val()).toFixed(2);`

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.
