Problem With Onchange Event In The Form (Geting Latitude And Longitude)

[nita]

Hi there !

 

What i'm traying to do is to get latitude and longitude form imputed postcodes.

Which works fine as long as i stick to only one input (first or second seperate).

I can't get it to work once i try with both of them.

i'm using onchange event ..

 

Please ake a look at the form:

<form name="latlon" action="test2a.php" method='post' onchange="return usePointFromPostcode(document.getElementById('postcode').value) && usePointFromPostcode1(document.getElementById('postcode1').value) ">
<input id="postcode" type="text" size="10" /><br>
<input id="postcode1" type="text" size="10"/><br>
Latitude:<input name="lat" type="text" id="lat" size="10"/><br />
Longitude:<input name="lon" type="text" id="lon" size="10"/><br><br>
Latitude:<input name="lat1" type="text" id="lat1" size="10"/><br />
Longitude:<input name="lon1" type="text" id="lon1" size="10"/>
<input type="submit" value="Get Lat / Lon"/>
</form>

 

and a Java Script used to get latitude and longitude:

 

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");
}

 

I'm totaly stuck here. What do i do wrong?

Will appreciate any help and thank you in advance.

Maybe i'm not clear enough here ...

 

all i want is to type in 2 postodes in the form so i can get their lat / lon and pass these values to another page, (hidden inputs to be used)

 

im not so much into javascript but maybe there is some other way ...

problem is in the form (getting lat / lon works fine)

 

any suggestions ...

 

Thank You

Postcode 1:<input id="postcode1" name="postcode1"type="text" size="10" onchange="usePointFromPostcode1(document.getElementById('postcode1').value)"/><br>
