    text
    copied!<p>I have a simple jQuery .post call that needs to process the returned data, and despite the numerous other similar posts, I cannot seem to get the syntax quite right.</p> <p>Here is my jquery call:</p> <pre><code>$.post("fetchAlleles.php", {mndx: mndx, sndx: sndx}, function(result) { $('#allele1').text(result[0]); $('#allele2').text(result[1]); }, "json"); </code></pre> <p>And here is the php code that is called:</p> <pre><code> $mndx = $_POST['mndx']; $sndx = $_POST['sndx']; $dbconnect = pg_pconnect("host=".$hostname." user=".$dbuser." dbname=".$dbname); if (!$dbconnect) { showerror(0,"Failed to connect to database",'fetchAlleles',16,"username=".$dbuser.", dbname=".$dbname); exit; } $sql = "SELECT allele1, allele2 FROM geno.genotypes WHERE markers_id=".$mndx." AND gsamples_id=".$sndx; $fetchresult = pg_exec($dbconnect, $sql); if ($fetchresult) { $arr = pg_fetch_array($fetchresult, 0, PGSQL_NUM); } else { echo "(25) Failed to retrieve results.&lt;BR&gt;SQL: ".$sql."&lt;/br&gt;"; } echo json_encode($arr); </code></pre> <p>Now, I know the php is working correctly, as I can see in Firebug that it returns the desired data. I just don't see how to access it using the success function. I want to assigned the return data to the value of the two elements id allele1 and allele2. </p> <p>I know I'm close, but haven't been able to find quite the right example, or decipher the jquery documentation. Any help will be much appreciated!</p> <p>--rixter</p> <p>EDIT 1: Here's the answer:</p> <p>$("#allele1").get(0).value = result[0]; $("#allele2").get(0).value = result[1];</p> <p>from Simanchal Pattanaik (found in another question)</p> <p>answered my question...thanks Simanchal!</p>
