Iterate through titanium views and look for class

ti.getViewByClass.js

/**
 * @function getViewByClass
 * @summary This will take a class and an optional parent and find children with that class
 * @param {string} _class Class name
 * @param {object} _parent Optional Parent View to iterate through
 * @param {number} _depth Optional depth of recursiveness
 * @returns {array} Array of views with the class
 * 
 * @TODO Implement _depth and recursive calls
 */ 
exports.getViewByClass = function(_class, _parent, _depth) {
    _parent = _parent || $.main;
    var classArray = [];
    _.each(_parent.children, function(child){
        if (child.className === _class) {
            classArray.push(child);
        }
    });
    
    return classArray;
};

ti.getViewByElement.js

/**
 * @function getViewByClass
 * @summary This will take a class and an optional parent and find children with that class
 * @param {string} _element Element name
 * @param {object} _parent Optional Parent View to iterate through
 * @param {number} _depth Optional depth of recursiveness
 * @returns {array} Array of views with the class
 * 
 * @TODO Implement _depth and recursive calls
 */ 
exports.getViewByElement = function(_element, _parent, _depth) {
  /* DOES NOT WORK AT ALL - NEED TO CHECK OUT THE CHILD PROPERTIES */
    _parent = _parent || $.main;
    var classArray = [];
    _.each(_parent.children, function(child){
        if (child.className === _class) {
            classArray.push(child);
        }
    });
    
    return classArray;
};

You need to replace class.push(child); with classArray.push(child); to get it working.

Also, the 3rd @param should be named _depth, not _parent.

Updated, thanks
