jQuery and Native JavaScript Array - error

var tmpANArray = [];
for (var i in associatedPpl) {
    tmpANArray.push(associatedPpl[i]);
}
alert('abo开发者_开发知识库ut to call toJSON on AssociatedPpl');
alert(tmpANArray);
// the next line fails because $.toJSON is getting fed a function
var jsonEncodedAssociatedPpl = $.toJSON(tmpANArray);

What part of JavaScript/jQuery am I missing?

UPDATE The JS JSON lib was jquery.json-1.3.min.js

You have your for cycle wrong, it is actually a foreach so your i variable should not be used to index the array, because its the value itself, change it to:

var tmpANArray = [];
for (var i in associatedPpl) {
    tmpANArray.push(i);
}

Or why not use the associatedPpl array directly?

there's no toJSON natively in Jquery. Do you mean to use getJSON()? Are you involving a function that you haven't provided information about?
