JavaScript code I'm starting with:
function doSomething(url) {
$.ajax({
type: "GET",
url: url,
dataType: "xml",
success: rssToTarget
});
}
Pattern I would like to use:
//where elem is the target that should receive new items via DOM (appendChild)
function doSomething(url, elem) {
$.ajax({
type: "GET",
url: url,
dataType: "xml",
success: rssToTarget(elem)
});
}
I don't think I can get the callback to work this way, right? What is the proper pattern? I don't want to use global variables necessarily to temporarily hold the elem
or elem name.
Like this...
function doSomething(url, elem) {
$.ajax({
type: "GET",
url: url,
dataType: "xml",
success: function(xml) {
rssToTarget(xml, elem);
}
});
}
Answer to your comment: Does use of anonymous functions affect performance?
