You can use each() or curry(). In this situation, you don't need a
certain scope so curry() is more suitable than bind(). See example below.
- Ken Snyder
// using each() makes each iteration call a function in its own scope
ret.each(function(data, i) {
var item = document.createElement('div');
var id = data.id[i]
var headline = data.headline[i];
var html = headline + "<hr />";
// don't forget to use a unique id value
item.id = "item" + i;
item.onclick = function(){fc.selectArticle(id, headline);};
item.innerHTML = html;
div.appendChild(item);
});
// using curry returns a new function with the current variable values
enclosed in that scope
for (i=0; i<rowCount; i++) {
var item = document.createElement('div');
var id = ret.id[i]
var headline = ret.headline[i];
var html = headline + "<hr />";
// don't forget to use a unique id value
item.id = "item" + i;
item.onclick = (function(id,
headline){fc.selectArticle(id,headline);}).curry(id, headline);
item.innerHTML = html;
div.appendChild(item);
}
