  1. POJavascript Onchange Event In the form (Getting Latitude And Longitude from Postcode)
    text
    copied!<p>What I'm trying to do is to get the latitude and longitude from imported postcodes. Which works fine as long as I stick to only one input (first or second separate). I can't get it to work once I try with both of them. I'm using the onchange event ..</p> <p>Please take a look at the form:</p> <pre><code>&lt;form name="latlon" action="test2a.php" method='post' onchange="return usePointFromPostcode(document.getElementById('postcode').value) &amp;&amp; usePointFromPostcode1(document.getElementById('postcode1').value) "&gt; &lt;input id="postcode" type="text" size="10" /&gt;&lt;br&gt; &lt;input id="postcode1" type="text" size="10"/&gt;&lt;br&gt; Latitude:&lt;input name="lat" type="text" id="lat" size="10"/&gt;&lt;br /&gt; Longitude:&lt;input name="lon" type="text" id="lon" size="10"/&gt;&lt;br&gt;&lt;br&gt; Latitude:&lt;input name="lat1" type="text" id="lat1" size="10"/&gt;&lt;br /&gt; Longitude:&lt;input name="lon1" type="text" id="lon1" size="10"/&gt; &lt;input type="submit" value="Get Lat / Lon"/&gt; &lt;/form&gt; </code></pre> <p>and in JavaScript this is what I used to get latitude and longitude:</p> <pre><code>function usePointFromPostcode(postcode, callbackFunction) { localSearch.setSearchCompleteCallback(null, function () { if (localSearch.results[0]) { var resultLat = localSearch.results[0].lat; var resultLng = localSearch.results[0].lng; var point = new GLatLng(resultLat, resultLng); document.forms['latlon'].lat.value = resultLat; document.forms['latlon'].lon.value = resultLng; callbackFunction(point); } else { alert("Postcode not found!"); } }); localSearch.execute(postcode + ", UK"); } function usePointFromPostcode1(postcode1, callbackFunction) { localSearch.setSearchCompleteCallback(null, function () { if (localSearch.results[0]) { var resultLat = localSearch.results[0].lat; var resultLng = localSearch.results[0].lng; var point = new GLatLng(resultLat, resultLng); document.forms['latlon'].lat1.value = resultLat; document.forms['latlon'].lon1.value = resultLng; callbackFunction(point); } else { alert("Postcode not found!"); } }); localSearch.execute(postcode1 + ", UK"); } </code></pre> <p>I'm totally stuck here. What am I doing wrong? Will appreciate any help and thank you in advance.</p>
