Pass a variable to a function from inside an ajax call

Question

I tried to use this loop to read some urls to read their modified time:

var arr = [];

//... fill arr with push

for (var e in arr) {
        nodename=arr[e].hos         


        

Answer 1

your are directly executing the method and passing its result as the callback for the success callback.

the xhr is already passed as the 3rd argument so try

success: function(nn,status, xhr) {
            $('#host_'+nn).append("last modified: " + xhr.getResponseHeader("Last-Modified"));
        }

if you have to pass the nodename as well, the you need to use a function that returns a function

success: (function(nn){
              return function(data ,status, xhr) {
                 // you can use nodename here...
                 $('#host_'+nn).append("last modified: " + xhr.getResponseHeader("Last-Modified"));
            };
        })(nodename)
