Question

I’m making an AJAX call which returns XML data, and this is my ‘success:’ function (callback):

success: function (data) { 
        var $rowArray = $(data).find("[nodeName=z:row]");
          $rowArray.each(function(index) { // for each date put it into calMap.
          calMap[$(this)[index].title] = $(this).attr("ows_Title");
          calMap[$(this)[index].date]  = $(this).attr("ows_EventDate");
          });
         }   

calMap is a global javascript object declared outside of the function.

var calMap = {};

What I want to do is create a function where I can pass in a title, have it search calMap for that title, and if found, the specific object is returned and I’ll be able to access the date property for that object.

Problem is, I can’t seem to access the data I insert into the calMap object. For starters, I just want to print the map. Tried eval‘ing it, tried alerting calMap[0], tried alerting calMap[0].title, but nothing. Can someone help me with this? Thanks!

Update:
I want to do something like this:

var data = getData("myTitle");

function getData(title) {
// if title is in calMap, something like this?
var result = (calMap[title])); 
return result;  // returns an object or NOTHING
}

then i’ll check if date is defined or not, and if it is, i’ll access its properties (ie. data.date. That make sense?

ANSWER:
I ended up using an array. STILL think I should be able to use the object MAP, but needed to get my project done.

Here’s the final code for the code that accesses the array items:

function hasCalDate(code)
{
    var matched = "";
    for (var f=0;f<calMap.length;f++){
        var re = new RegExp(code);
        if (re.test(calMap[f].title))
        {
        matched = calMap[f].title+','+calMap[f].date;
        }
    }
return matched;
};

Thanks everyone.

You need to initialize calMap as an array (i.e. square brackets, not curly ones):

var calMap = [];

Then, inside your each function, I’m guessing you want something more like

calMap.push({
    title: $(this).attr("ows_Title"),
    date: $(this).attr("ows_EventDate")
});
