Reading Twitter RSS with Google Feeds API - javascript

I have written this code:
<script type="text/javascript" src="https://www.google.com/jsapi"></script>
<script type="text/javascript">
google.load("feeds", "1");
function initialize() {
var feed = new google.feeds.Feed("http://search.twitter.com/search.rss?q=HMTL5");
feed.setNumEntries(100);
feed.includeHistoricalEntries();
//feed.setResultFormat(google.feeds.Feed.XML_FORMAT);
feed.load(function(result) {
if (!result.error) {
for (var i = 0; i < result.feed.entries.length; i++) {
var entry = result.feed.entries[i];
alert(entry.title);
alert(entry.author);
alert(entry.WHAT_SHOULD_I_TYPE_HERE);
}
I am able to get the title and author, but not the image. I need to extract the user image URL from tag but don't know how. Help appreciated.

Did you get an Answer to your Question? Why not add the following line under 'var entry =' and post the result:
var entry = result.feed.entries[i];
console.log(entry);
Or post the URL TAG output

Creating multiple array lists

Re-worded objective:
I'm creating a web page using google apps script. I want to have multiple drop downs listed on the page. I know if I use <select><option>, I can create a list of hard coded options. What I would rather do is grab the options from a google sheet to display in the drop down, this way I can update it at anytime without modifying the HTML code.
The issue: While I was successful in creating a drop down selection containing Column A values from my sheet, I'm running into an issue where Apps Script will not let me create another drop down containing the values of Column B.
This is my sheet that contains names and dietary types. Each column contains the options for each drop down.
This is what it looks like on the front end. I'd like to have another drop down beside it that contains values from Column B (as seen above).
Here is my script:
var url = "google sheets URL";
function doGet(e){
var ss = SpreadsheetApp.openByUrl(url);
var ws = ss.getSheetByName("Staff");
var list = ws.getRange(1,1,ws.getRange("A1").getDataRegion().getLastRow(),1).getValues();
var tmp = HtmlService.createTemplateFromFile("index");
tmp.list = list.map(function(r){ return r[0]; });
return tmp.evaluate();
}
This is the HTML for my selection list:
<select id="app" class="browser-default">
<option disabled selected>Select a teammate!</option>
<? for(var i=0;i<list.length;i++){ ?>
<option><?= list[i]; ?></option>
<? } ?>
</select>
It functions correctly at this point but when trying to replicate it so I can grab another column in Google Sheets and use that as another selection list,
I get: Referenceerror: "list" is not defined.
This is the script that's causing me to get the error.
var url = "google sheets URL";
function doGet(e){
var ss = SpreadsheetApp.openByUrl(url);
var ws = ss.getSheetByName("Staff");
var list = ws.getRange(1,1,ws.getRange("A1").getDataRegion().getLastRow(),1).getValues();
var tmp = HtmlService.createTemplateFromFile("index");
tmp.list = list.map(function(r){ return r[0]; });
return tmp.evaluate();
}
function doGet(f){
var ss = SpreadsheetApp.openByUrl(url);
var ws = ss.getSheetByName("Variables");
var list2 = ws.getRange(1,1,ws.getRange("A1").getDataRegion().getLastRow(),1).getValues();
var tmp2 = HtmlService.createTemplateFromFile("index");
tmp2.list2 = list2.map(function(r){ return r[0]; });
return tmp2.evaluate();
}
Here's a simple example of getting multiple list from a dialog.
Load the code and run launchDialog(). You could also add a doGet() and use return HtmlService.createHtmlOutputFromFile('aq4');
Code.gs:
function getList(n) {
var ss=SpreadsheetApp.getActive();
var sh=ss.getSheetByName('Sheet1');
var rg=sh.getRange(2,n,sh.getLastRow()-1,1);
return rg.getValues().map(function(r){return r[0]});
}
function launchDialog() {
var userInterface=HtmlService.createHtmlOutputFromFile('aq4');
SpreadsheetApp.getUi().showModelessDialog(userInterface, 'My List');
}

Tableau JavaScript API - get Selected value

I am currently researching the possibility to grabbing data from the Tableau report(s) via the JavaScript API but the closet I can get to grabbing values from a graph after filtering is selecting the value via the selectSingleValue() method.
For example: JavaScript API Tutorial
In the API tutorial tab called 'Select'. One of the examples selects the row "Marcao Sao, China". Is it possible to extract that numerical value of $52.0k ?
I have tried looking into the Objects returned (via FireBug) but I cannot seem to locate the right object. My recent location was in getActiveSheets().
Any help would be appreciated.
In the JavaScript API tutorial tab 'Events' it shows you how to add an event listener to return the selected marks. You can then loop through the marks to get the values you want.
Copy the below code block into a file, save as html and open in your favourite web browser (tested on ie11).

Changing the number of results using Google Feed API

I'm trying increase the number of items that appear on this webpage using the Google Feed API to 25 instead of 4 items:
http://ewh.ieee.org/reg/1/sac/news.php
Here is the JS:
<script src="//www.google.com/jsapi?key=AIzaSyA5m1Nc8ws2BbmPRwKu5gFradvD_hgq6G0" type="text/javascript"></script>
<script type="text/javascript">
google.load("feeds", "1");
function feedLoaded(result) {
if (!result.error) {
var container = document.getElementById("content");
container.innerHTML = '';
for (var i = 0; i < result.feed.entries.length; i++) {
var entry = result.feed.entries[i];
var div = document.createElement("div");
div.appendChild(document.createTextNode(i + ': ' + entry.title));
container.appendChild(div);
}
}
}
function OnLoad() {
var feedControl = new google.feeds.FeedControl();
feedControl.addFeed("http://feeds.feedburner.com/IeeeSpectrum", "Latest IEEE Spectrum News:");
feedControl.draw(document.getElementById("content"));
feed.includeHistoricalEntries(); // tell the API we want to have old entries too
feed.setNumEntries(25); // we want a maximum of 25 entries, if they exist
feed.load(feedLoaded);
}
google.setOnLoadCallback(OnLoad);
</script>
And the HTML:
<body style="font-family: Arial;border: 0 none;">
<div id="content">Loading IEEE Spectrum News...</div>
</body>
I tried using feed.setNumEntries(), but it doesn't seem to work. I appreciate any help. Thank you.
I found the solution to my problem:
<script type="text/javascript">
google.load("feeds", "1");
function initialize() {
var control = new google.feeds.FeedControl();
control.setNumEntries(25);
control.addFeed("http://feeds.feedburner.com/IeeeSpectrum", "Latest IEEE Spectrum News:");
control.draw(document.getElementById("content"));
}
google.setOnLoadCallback(initialize);

Using Google Images API

I'm trying to use Google's Images API to search an image and put it into my html document as a div. This is what I have so far, but nothing seems to be appearing. This is parts from http://code.google.com/apis/imagesearch/v1/devguide.html. This is my first time using an API, so I'm not sure what is really going on.

Thanks in advance!
It can't work because you are looking for a HTMLElement that has the ID='content', you haven´t anyone element with that ID
Try putting your js functions within <head></head>

</gml:posList>
</gml:LineString>
this can not get using the google ajax api .
so what should i do ..
You need to load the XML feed instead of the JSON feed to be able to get the raw XML feed as it is. With the JSON feed, it removes all but the standard RSS and Atom tags and then translates to JSON.
Set the result format to XML as
var feed = new google.feeds.Feed("...");
feed.setResultFormat(google.feeds.Feed.XML_FORMAT);
Here is a modified load function to print XML namespaced elements such as georss:point and gml:LineString.
feed.load(function(result) {
var georssNS = "http://www.georss.org/georss";
var gmlNS = "http://www.opengis.net/gml";
var items = result.xmlDocument.getElementsByTagName("item");
for(var i = 0; i < items.length; i++) {
// get <georss:point>
var georss = google.feeds.getElementsByTagNameNS(items[i], georssNS, "point")[0];
if(georss) {
console.log(georss)
}
// get <gml:LineString>
var lineString = google.feeds.getElementsByTagNameNS(items[i], gmlNS, "LineString")[0];
if(lineString) {
console.log(lineString);
}
}
});
From an example in the Google AJAX API Code Playground that works
http://code.google.com/apis/ajax/playground/?exp=feeds#load_feed
/*
* How to load a feed via the Feeds API.
*/
google.load("feeds", "1");
// Our callback function, for when a feed is loaded.
function feedLoaded(result) {
if (!result.error) {
// Grab the container we will put the results into
var container = document.getElementById("content");
container.innerHTML = '';
// Loop through the feeds, putting the titles onto the page.
// Check out the result object for a list of properties returned in each entry.
// http://code.google.com/apis/ajaxfeeds/documentation/reference.html#JSON
for (var i = 0; i < result.feed.entries.length; i++) {
var entry = result.feed.entries[i];
var div = document.createElement("div");
div.appendChild(document.createTextNode(entry.title));
container.appendChild(div);
}
}
}
function OnLoad() {
// Create a feed instance that will grab Digg's feed.
var feed = new google.feeds.Feed("http://maps.google.com/maps/ms?ie=UTF8&hl=zh-CN&vps=1&jsv=259e&msa=0&output=georss&msid=109685068115364659392.00048b5b630141d82b83a");
// Calling load sends the request off. It requires a callback function.
feed.load(feedLoaded);
}
google.setOnLoadCallback(OnLoad);
