    text
    copied!<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>
