"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);
