Change values in <td>'s with jquery <p>I have a table of values. Is it possible with JQuery by clicking on currency link to change value in cells with exchange rates? This static example table</p> <pre><code>&lt;table border="1"&gt; &lt;tr&gt; &lt;td class="currency"&gt;100&lt;/td&gt; &lt;td class="currency"&gt;200&lt;/td&gt; &lt;td class="current"&gt;now in USD&lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td class="currency"&gt;150&lt;/td&gt; &lt;td class="currency"&gt;230&lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td class="currency"&gt;400&lt;/td&gt; &lt;td class="currency"&gt;200&lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td class="currency"&gt;550&lt;/td&gt; &lt;td class="currency"&gt;2920&lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; &lt;a href="#" class="USD"&gt;USD&lt;/a&gt; &lt;a href="#" class="EUR"&gt;EUR&lt;/a&gt; </code></pre> <p>Pls look <a href="http://jsfiddle.net/halofourteen/PjPYV/2/" rel="nofollow">jsfiddle</a>. In other words by clicking on currency values must recalculate them according to rates. In my example on jsfiddle I want to understand how simply change value(for example <code>usd=1</code> <code>eur=1.3</code>) Thanks!</p>
