[Proto-Scripty] Re: Variables in $$() ?????
Thanks for that but like most things in the prototype documentation,
it
lacks the type of clarity that I can understand.
Nice way to get help... Your docs suck so just spoon feed me the
answer
The answer to your initial approach is an issue with basic javascript
string behavior and was nailed on the head by both Johnathon and David
var myVariableValue = 3;
var mySelector = input[type=radio][name='type']
[value='myVariableValue'];
In the above expression the value of myVariableValue isn't evaluated,
its literally written into the string as is, hence its not the value 3
its the string value myVariableValue
Hope you like puree'd corn template
var myTemplate = new Template(input[type=#{type}][name='#{name}']
[value='#{value}']);
var dto = { type : 'radio', name : 'type', value : '3' };
var selector = myTemplate.evaluate(dto);

need to look elsewhere.

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){

The problem with your original code was as as Jonathan said, you were
passing the string input[type=radio][name='type'][value=selectThis]
into $$ as the selector. David's suggestion fixes that by using the
*value* of selectThis rather the actual text selectThis. As the live

I've hit this in two seperate places and not exactly sure why...
(I think its the 18 hour days, 7 days a week... g)
If value is hard set with '3' the following works:
$$(input[type=radio][name='type'][value='3'])[0].writeAttribute(checked
,
checked);
However, if we use a variable (selectThis) and assign it 3 it does not
work.
var selectThis;
selectThis = '3';
$$(input[type=radio][name='type'][value=selectThis])[0].writeAttribute(c
hecked,
checked);
Type casting doesn't work either:
var selectThis;
selectThis = String('3');
$$(input[type=radio][name='type'][value=selectThis])[0].writeAttribute(c
hecked,
checked);
I'm having the same problem here too (compare o.value== 'GA' and the
select gets set to GA):
selectThis = 'GA'
$$('select#ajstate option').each(function(o){
if(o.value==selectThis){o.selected = true;$break;}
});
What am I missing here?
