Object doesn't support this property or method

Hi All,

I am getting an error that says "Object doesn't support this property or method"

It points to this line return ary.filter(function(elem) {  

	 $().SPServices({
	    operation: "GetListItems",
		listName: "Projects",
		async: false,
		CAMLViewFields: "<ViewFields><FieldRef Name='SiteProjectedAmount' /></ViewFields>",
		CAMLQuery: cml,
		CAMLRowlimit:100,
		completefunc: function (xData, Status) {	
		//alert(xData.responseXML.xml);
		$(xData.responseXML).find("z\\:row").each(function () {		
				var ProjectItem = new Object();
				ProjectItem["AmountProjected"] = checkForUndefined($(this).attr("ows_SiteProjectedAmount"));
				ProjectItem["ProjectNumber"] = $(this).attr("ows_ProjectNumber");
		
				AnnualizedDataArray.push(ProjectItem);
				/*var x = checkForUndefined($(this).attr("ows_SiteProjectedAmount"));
				annualCost += parseFloat(x);*/
		  });
		}
	 });
	 
var uniqBy = function(ary, key) {
    var seen = {};
    return ary.filter(function(elem) {
        var k = key(elem);
        return (seen[k] === 1) ? 0 : seen[k] = 1;
    })
}

uniqs = uniqBy(AnnualizedDataArray, JSON.stringify);
values = uniqs.map(function(x) { for(var k in x) return x[k] });
annualCost = values.reduce(function(a, b) { return a + b });

It works in jsfiddle. http://jsfiddle.net/GTpgA/41/

Any ideas?

Thanks!

What javascript framework are you using?  in your fiddle you're using mootools but this topic is listed at jQuery.  jQuery has its own filter function that may interfere but I'm suspecting after a bit of testing (changing your fiddle to use jQuery then no framework and it's still working) that the actual error is elsewhere in your code.

I would output to the console (console.log() instead of alert, you'll see more) the contents of AnnualizedDataArray before the uniqBy function, for instance to see if the data is in the format you expect.

What's the best way to see what's in an array?  This is all being done in SharePoint which is really a web page.

If you use console.log() it will dump the contents of the stay to the console. You can get to the console vis the developer tools by pressing f12

so in other words:

console.log(AnnualizedDataArray);
uniqs = uniqBy(AnnualizedDataArray, JSON.stringify);
