Parameters

[AdRock952]

I have got a function for geocoding and would like to know if and how I can set parameters in the function

This is the function which takes a postcode as a parameter

Postcode Lookup : <input type="text" id="formPostcode" value="
<input type="button" value="Lookup (incorrect)"  onclick="incorrectGeocodeLookup(document.getElementById('formPostcode'));"/>"

/>

this is the funcion

function startGeocodeLookup(elem) {
    	    var postcode=elem.value;
    	    var formLat=document.getElementById('formLat');
    	    var formLong=document.getElementById('formLong');
    	    usePointFromPostcode(postcode,
    	    function (point) {
		if (!point) {
		    alert(postcode + " not found");
		} else {
		    formLat.value=point.lat();
          	    formLong.value=point.lng();
		}
	    }
	    );
        }

would it be possible to pass some more parameters so in these 2 lines i can choose which form elements to pass it?

var formLat=document.getElementById('formLat');
var formLong=document.getElementById('formLong');

would this work

function startGeocodeLookup(elem, start, finish) {
    	    var postcode=elem.value;
    	    var formLat=start;
    	    var formLong=finish;
    	    usePointFromPostcode(postcode,
    	    function (point) {
		if (!point) {
		    alert(postcode + " not found");
		} else {
		    formLat.value=point.lat();
          	    formLong.value=point.lng();
		}
	    }
	    );
        }

<input type="button" value="" onclick="workingGeocodeLookup(document.getElementById('formPostcode', formStart, formFinish));"/>

No, but this would:

<input type="button" value="" onclick="workingGeocodeLookup(document.getElementById('formPostcode'), formStart, formFinish);"/>

Just change the closing bracket position.

Also, you should consider using unobtrusive javascript instead of ancient-style inline event listeners.
