jQuery widget method not being detected

For the life of me I cannot see the suttle difference between copied code. The _getMiscData method in a child widget apparently doesn't exist according to the parent widget. Can someone explain this?
I tried different method names in case I was using a reserved word. I tried private and public method with same result.
$(function() {
$.widget("custom.textquestion", $.custom.base, {
_create: function() {
this.element.data("_getControlValue", this.getControlValue());
},
getControlValue: function() {
this.element.attr("usersanswer", this.getResponseJSON());
},
_getAnswerSelection: function(answer) {
var qname = this._getQuestionName();
var type = this.getType();
return '<div class="radio span6"><label><input type="text" class="answerfield" name="optradio-' + qname + '" value="' + answer.answertext + '"></label></div>'
},
_getAnswersDiv: function(answers) {
// DIV is required for wrapping around list of answers
// so that they can be added all at once.
var answerdivs = '<div class="answerlist">'
for (k = 0; k < answers.length; k++) {
answerdivs += this._getAnswerSelection(answers[k]);
}
answerdivs += '</div>';
return answerdivs;
},
_getPopulatedEditor: function(answers) {
var editanswerdiv = "";
for (p = 0; p < answers.length; p++) {

The custom.base widget shouldn't return with "this.getMiscData is not a function"

Replacing placeholder values within a string

Not sure why my code is not working because the code I took from below is working in JSFiddle here
String.prototype.interpolate = (function() {
var re = /\[(.+?)\]/g;
return function(o) {
return this.replace(re, function(_, k) {
return o[k];
});
}
}());
var _obj = {
hey: 'Hey',
what: 'world',
when: 'today'
}
document.write(
'[hey]-hey, I saved the [what] [when]!'.interpolate(_obj)
);
But my code below doesn't seem to be doing the same thing. It still has the bracket values [NAME][ADDRESS][PHONE] and not the replaced data values:
$(document).ready(function () {
$('#goSearching').click(function () {
var isNumber = $.isNumeric($('#searchBox').val());
var theSearch = $('#searchBox').val();
var theURL = '';
if (isNumber) {
if (theSearch.length >= 10) {
//Search by NPI#
$('#titleOfSearchResult').html('P search results by NPI #:');
theURL = 'http://zzzzz.com:151/P/GetNPI/';
} else {
//Search by P #
$('#titleOfSearchResult').html('P search results by P #:');
theURL = 'http://zzzzzz.com:151/P/GetNo/';
}
} else {
//Search by P Name
$('#titleOfSearchResult').html('P search results by P Name:');
theURL = 'http://zzzzz.com:151/P/PName/';
}
$.ajax({
url : theURL + $('#searchBox').val() + '/',
type : 'GET',
dataType : 'xml',
timeout : 10000,
cache : false,
crossDomain : true,
success : function (xmlResults) {
console.log(xmlResults);
var _htmlObj = {};
$(xmlResults).find("P").each(function() {
_htmlObj = {
NAME : $(this).find("pName").text(),
ADDRESS : $(this).find("pSpecialty").text(),
PHONE : $(this).find("pUserid").text()
}
console.log($(this).find("pName").text());
console.log($(this).find("pSpecialty").text());
console.log($(this).find("pUserid").text());
$("#theResults").append(
'<p><strong>[NAME]</strong></p>' +
'<p>[ADDRESS]</p>' +
'<p>[PHONE]</p>' +
'<p> </p>'.interpolate(_htmlObj)
);
});
},
error : function(jqXHR, textStatus) {
console.log("error: " + textStatus);
}
});
});
String.prototype.interpolate = (function () {
var re = /\[(.+?)\]/g;
return function (o) {
return this.replace(re, function (_, k) {
return o[k];
});
}
}());
});
In the console it outputs the correct returned values but it won't replace those values with the placeholders [NAME][ADDRESS][PHONE].
Any help to fix this issue would be great! Thanks!

You're only calling interpolate on the last string
'<p><strong>[NAME]</strong></p>' +
'<p>[ADDRESS]</p>' +
'<p>[PHONE]</p>' +
'<p> </p>'.interpolate(_htmlObj)
Member access has a higher precedence than addition, so it needs to be:
('<p><strong>[NAME]</strong></p>' +
'<p>[ADDRESS]</p>' +
'<p>[PHONE]</p>' +
'<p> </p>').interpolate(_htmlObj)

How to count duplicate array elements? (javascript)

I'm trying to make an XML based menu with JavaScript, XML and jQuery. I've been successful at getting the categories of the menu, but haven't been able to generate the items in the categories.
My script is as follows, and later in this thread, I've asked for suggestions for this code:
var animalsXMLurl = 'http://dl.dropboxusercontent.com/u/27854284/Stuff/Online/XML_animals.xml';
$(function() {
$.ajax({
url: animalsXMLurl, // name of file you want to parse
dataType: "xml",
success: function parse(xmlResponse) {
var data = $("item", xmlResponse).map(function() {
return {
id: $("animal_id", this).text(),
title: $("animal_title", this).text(),
url: $("animal_url", this).text(),
category: $("animal_category", this).text().split('/'),
};
}).get();
var first_item = category_gen(data, 0);
$('ul.w-nav-list.level_2').append(first_item);
var categnumber = new Array();
for (i = 1; i <= data.length; i++) //for splitting id, and getting 0 for category_number (1 or 2 or 3...and so on)
{
categnumber[i] = data[i].id.split('_');
console.log(categnumber[i][0]);
for (j = 1; j <= data.length; j++) //appending via a function.
{
var data_text = category_or_animal(data, categnumber, j);
console.log(data_text);
$('ul.w-nav-list.level_2').append(data_text);
}
}
function category_or_animal(d, catg, k) {
var catg1 = new Array();
var catg2 = new Array();
var catg1 = d[k].id.split('_');
if (d[k - 1]) {
var catg2 = d[k - 1].id.split('_');
//if(d[k-1].id)
if (catg1[0] != catg2[0])
return category_gen(d, k);
} else
return '</ul>' + animal_gen(d, k);
}
function category_gen(d, z) {
var category_var = '<li class="w-nav-item level_2 has_sublevel"><a class="w-nav-anchor level_2" href="javascript:void(0);"><span class="w-nav-title">' + d[z].category + '</span><span class="w-nav-arrow"></span></a><ul class="w-nav-list level_3">';
return category_var;
}
function animal_gen(d, z) {
var animal_var = '<li class="w-nav-item level_3"><a class="w-nav-anchor level_3" href="animals/' + d[z].url + '"><span class="w-nav-title">' + d[z].title + '</span><span class="w-nav-arrow"></span></a></li>';
return animal_var;
}
}, error: function() {
console.log('Error: Animals info xml could not be loaded.');
}
});
});
Here's the JSFiddle link for the above code: http://jsfiddle.net/mohitk117/d7XmQ/4/
In the above code I need some alterations, with which I think the code might work, so I'm asking for suggestions:
Here's the function that's calling separate functions with arguments to generate the menu in above code:
function category_or_animal(d, catg, k) {
var catg1 = new Array();
var catg2 = new Array();
var catg1 = d[k].id.split('_');
if (d[k - 1]) {
var catg2 = d[k - 1].id.split('_');
//if(d[k-1].id)
if (catg1[0] != catg2[0])
return category_gen(d, k);
} else
return animal_gen(d, k) + '</ul>';
}
At the if(catg1[0] != catg2[0]) it checks if the split string 1_2 or 1_3 is equal to 1_1 or 1_2 respectively. By split, I mean the first element: 1 .... if you have a look at the xml: [ :: Animals XML :: ], you'll see that the animal_id is in the format of %category_number% _ %item_number% ... So I need to create the menu with CATEGORY > ITEM (item=animal name)
Now if I could return category_gen() + animal() with animal(){ in a for loop for all the matching category id numbers} then maybe this could be complete! But I don't of a count script for conditioning the for loop (i=0;i<=count();i++)...
Would anyone know of how to get this script functioning?

Hard to tell what the provided JSFiddle is trying to do.
This is my best stab at it. I used JQuery to parse the XML out into categories and generate lists of items.
http://jsfiddle.net/d7XmQ/8/
"use strict";
var animalsXMLurl = 'http://dl.dropboxusercontent.com/u/27854284/Stuff/Online/XML_animals.xml';
$(function () {
var $menu = $('#menu');
$.ajax({
url: animalsXMLurl, // name of file you want to parse
dataType: "xml",
success: handleResponse,
error: function () {
console.log('Error: Animals info xml could not be loaded.');
}
});
function handleResponse(xmlResponse) {
var $data = parseResponse(xmlResponse);
createMenu($data);
}
function parseResponse(xmlResponse) {
return $("item", xmlResponse).map(function () {
var $this = $(this);
return {
id: $this.find("animal_id").text(),
title: $this.find("animal_title").text(),
url: $this.find("animal_url").text(),
category: $this.find("animal_category").text()
};
});
}
function createMenu($data) {
var categories = {};
$data.each(function (i, dataItem) {
if (typeof categories[dataItem.category] === 'undefined') {
categories[dataItem.category] = [];
}
categories[dataItem.category].push(dataItem);
});
$.each(categories, function (category, categoryItems) {
var categoryItems = categories[category];
$menu.append($('<h2>').text(category));
$menu.append(createList(categoryItems));
});
}
function createList(categoryItems) {
var $list = $('<ul>');
$.each(categoryItems, function (i, dataItem) {
$list.append(createItem(dataItem));
});
return $list;
}
function createItem(dataItem) {
return $('<li>').text(dataItem.title);
}
});

You can solve this without using any for/while loop or forEach.
function myCounter(inputWords) {
return inputWords.reduce( (countWords, word) => {
countWords[word] = ++countWords[word] || 1;
return countWords;
}, {});
}
Hope it helps you!

Autocomplete with javascript, not passing the variables

I'm using this autocomplete code to be able to pull stock information:
var YAHOO = {};
YAHOO.util = {};
YAHOO.util.ScriptNodeDataSource = {};
var stockSymbol;
var compName;
YUI({
filter: "raw"
}).use("datasource", "autocomplete", "highlight", function (Y) {
var oDS, acNode = Y.one("#ac-input");
oDS = new Y.DataSource.Get({
source: "http://d.yimg.com/aq/autoc?query=",
generateRequestCallback: function (id) {
YAHOO.util.ScriptNodeDataSource.callbacks =
YUI.Env.DataSource.callbacks[id];
return "&callback=YAHOO.util.ScriptNodeDataSource.callbacks";
}
});
oDS.plug(Y.Plugin.DataSourceJSONSchema, {
schema: {
resultListLocator: "ResultSet.Result",
resultFields: ["symbol", "name", "exch", "type", "exchDisp"]
}
});
acNode.plug(Y.Plugin.AutoComplete, {
maxResults: 10,
resultTextLocator: "symbol",
resultFormatter: function (query, results) {
return Y.Array.map(results, function (result) {
var asset = result.raw,
text = asset.symbol +
" " + asset.name +
" (" + asset.type +
" - " + asset.exchDisp + ")";
return Y.Highlight.all(text, query);
});
},
requestTemplate: "{query}&region=US&lang=en-US",
source: oDS
});
acNode.ac.on("select", function (e) {
alert(e.result.raw.name);
stockSymbol = e.result.raw.symbol;
compName = e.result.raw.name;
alert("stockSymbol is "+stockSymbol);
alert("compName is "+compName);
});
});
I have a text field where the text is being entered, then I need to display a few pieces of information based on what was entered:
$(document).ready(function(e) {
//$(".selector").button({icons: {primary: "ui-icon-search"}});
//$(".home").button({icons: {primary: "ui-icon-home"}});
var q = window.location.href.split("?ac-input=");
alert("q is "+q)
if (q && q[1])
$("input").val(q[1]);
alert("what is this?" +q[1]);
runForm();
});
..........
function runForm(){
$("#stock_news").html("");
//var stockSymbol = e.result.raw.symbol;
alert('stockSymbol in runForm is ' +stockSymbol);
alert('compname is runForm is '+compName);
var newsStocks = "http://query.yahooapis.com/v1/public/yql?.......";
$.getJSON(newsStocks, function(data) {
var headlines = data.query.results.a;
newStr = "<h3>Current Headlines</h3>";
newStr += "<ol>";
for(var i=0; i<headlines.length; ++i){
var news = headlines[i];
newStr += "<li><a href='"+news.href+"'>"+news.content+"</a></li>";
}
newStr += "</ol>";
$("#stock_news").html(newStr);
});
htmlStr = '<img src="http://chart.finance.yahoo.com/z?s='+stockSymbol+'&t=5d&q=l&l=off&z=s&region=US&lang=en-EN"/>';
$("#stock_graph").html(htmlStr);
}
What is happening is, the stockSymbol and compName are correctly set from entering, but for some reason nothing renders on the page, as q is undefined....Any ideas on where I am messing up here?
Figured it out. I needed to call runForm inside the acNode.ac.on("select", function (e)

PhantomJS -- Scraping data feed -- Some AJAX content not loading, even with generous setTimeout

I have a generic PhantomJS setup for scraping feeds (we are doing this with owner's permission, for a client) -- you give it a URL, jQuery/javascript code for turning the page, and a selector to select links from the feed.
