Morning TJ!
I know it SHOULD work... I'm just saying it didnt.
works:
// set radio button for type
selectThis = {selectID: 'type', selectValue:
transport.responseXML.getElementsByTagName('type')[0].firstChild.nodeValue
};
$$(radioTemplate.evaluate(selectThis))[0].writeAttribute("checked",
"checked");
didn't work:
var selectThis
= transport.responseXML.getElementsByTagName('type')[0].firstChild.nodeValue;
$$("input[type=radio][name='type'][value='" + selectThis +
"']").writeAttribute("checked", "checked");
ALSO:
This works:
selectThis = {matchString:
transport.responseXML.getElementsByTagName('state')[0].firstChild.nodeValue
};
$$('select#ajstate option').each(function(o){
if(o.value == selectTemplate.evaluate(selectThis)){o.selected =
true;$break;}
});
But moving it into a function doesn't:
setSelect('ajState',
transport.responseXML.getElementsByTagName('state')[0].firstChild.nodeValue);
function setSelect(strID, strValue)
{
var selectIDTemplate = new Template('#{matchID}');
var selectTemplate = new Template('#{matchString}');
var selectThis;
var selectID;
selectID = {matchID: strID};
selectThis = {matchString: strValue };
$$('select#selectIDTemplate.evaluate(selectID) option').each(function(o){
if(o.value == selectTemplate.evaluate(selectThis)){o.selected =
true;$break;}
});
}
I think I am either daft or extremely tired! LOL
