Javascript Prototype Best Practice Event Handlers
- by nahum
Hi this question is more a consulting of best practice, Sometimes when I'm building a complete ajax application I usually add elements dynamically for example. When you'r adding a list of items, I do something like:
var template = new Template("<li id='list#{id}'>#{value}</li>");
var arrayTemplate = [];
arrayOfItem.each(function(item, index){
arrayTemplate.push(template.evaluate( id : index, value : item))
});
after this two options add the list via "update" or "insert"
----- $("elementToUpdate").update("<ul>" + arrayTemplate.join("") + "</ul">);
the question is
how can I add the event handler without repeat the process of read the array, this is because if you try add a Event before the update or insert you will get an Error because the element isn't still on the DOM.
so what I'm doing by now is after insert or update:
arrayOfItem.each(function(item, index){
$("list" + index).observe("click", function(){
alert("I see the world");
})
});
so the question is exist a better way to doing this??????
