    copied!<p>I would handle this problem differently.</p> <p>I would assign a unique ID only to each "block" of data. Within that block I would only use classes to identify each element of the data. </p> <p>Each class within one block would be unique.</p> <p>So this is what my HTML would look like (note the class rename to make them unique within each data block)</p> <pre><code>&lt;div id="data1" class="RedColor" &gt; &lt;table class="recordTable"&gt; &lt;tr&gt; &lt;td class="studentNameData"&gt; &lt;table class="innerTab" border="0" width="100%" cellpadding="3"&gt; &lt;tr&gt; &lt;td class="studentName"&gt; ... &lt;/td&gt; ... &lt;/table&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; &lt;/div&gt; &lt;div id="data2" class="RedColor" &gt; &lt;table class="recordTable"&gt; ... </code></pre> <p>You could even get rid of the <code>div</code> wrapper and put the unique ID on each outer table.</p> <p>Now each piece of data can be uniquely identified using the form: <code>[ Data Block ID ] [ Class Name ]</code>.</p> <p>In jQuery that can be done using the <strong><a href="http://api.jquery.com/find/" rel="nofollow noreferrer"><code>.find()</code></a></strong> method.</p> <p>For example to retrieve the studentName from data block 3 I would use</p> <pre><code> $("#data3").find(".studentName").text(); </code></pre> <p>I would iterate over the data you get from the server to populate the tables. Here is an extremely simplified version just to illustrate what I described. I removed the outer DIV wrapper and added the unique ID to the table, just so you can see what that would look like: <br/></p> <h2>Simplified example:</h2> <pre><code>// Function to add an empty table with class names var $addTable = function() { // The table could be built with multiple methods too. return $('&lt;table&gt;&lt;tr&gt;&lt;td class ="name"&gt;&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;'); } $(function() { // The attribute = selector $("input[value='Get data']").click(function() { // Loading notice $("#showData").html("Loading..."); // The AJAX call to get the data using POST $.post('/ajax_json_echo/', function(data) { // Clear loading notice $("#showData").html(""); // Iterate through data // and create a table for each item. $.each(data, function(index, value) { // This is the div's unique ID var $id = "data" + index; $addTable().attr("id", $id).appendTo("#showData"); $("#" + $id).find(".name").html(value); }); }); }); });​ </code></pre> <h2><strong><a href="http://jsfiddle.net/Q9yHD/" rel="nofollow noreferrer">jsFiddle example</a></strong></h2>
