Is there a way to use gdata api to retrieve the list of all labels in a blogger?
I need to create a menu based on that list, but cannot simply list all posts and get it, because it is a busy blog and has more than 2000 posts.
Here is the most easy way to get a list of labels by using json call:
<script>
function cat(json){ //get categories of blog & sort them
var label = json.feed.category;
var lst=[];
for (i=0; i<label.length; i++){
lst[i] = label[i].term ;
}
alert(lst.sort()); //use any sort if you need that
}
</script>
<script src="http://yourblog.blogspot.com/feeds/posts/summary?alt=json&max-results=0&callback=cat"></script>
Just use your blog url.
Very simple, I give you two ways
With Javascript API
First, you must use:
<script type="text/javascript" src="http://www.google.com/jsapi"></ script>
<script type='text/javascript'>
google.load("gdata", "1.x", { packages : ["blogger"] });
</script>
Second, you can use the code below to retrieve the labels
postRoot.entry.getCategories()[i].getTerm()
For more tutorials, you can read from http://www.threelas.com/2012/05/how-to-retrieve-posts-using-blogger.html and http://www.threelas.com/2012/04/basic-blogger-javascript-api.html
With JSON
with json, if you want to learn how to retrieve the list of labels, use this object
json.feed.entry[i].category[j].term
for more detail tutorials, read from http://www.threelas.com/2012/02/basic-blogger-json-feed-api.html and http://www.threelas.com/2012/09/blogger-json-feed-with-jquery-ajax.html
The way I found was using the Blogger's own gadget called Labels. It prints the list of labels and their usage count within some unordered lists(ul) and links(a). You can pull the labels from that after they are loaded using javascript as follows:
$(".list-label-widget-content a").each(function (i, el) {
var labelText = $(el).text();
// do what you want with the labels
});
in the end, remove the Labels div element (<div class='widget Label' id='Label1'>)
Widget to server the same purpose is provided by bloggers itself.
Widget provides various options like -
You can either show all Labels or choose from your existing List
You can sort the Labels alphabetically or by number of times that label is used (frequency).
You can choose to display these as a List or as a cloud (jumbled).
You can see the same in my blog - Link
I don't see a method to get the list of labels in a blog, but you can retrieve all posts (https://developers.google.com/blogger/docs/2.0/json/reference/posts/list) and check the labels field for each of them: https://developers.google.com/blogger/docs/2.0/json/reference/posts#resource
First add the JQuery through the following code in console.
var jq = document.createElement('script');
jq.src = "https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js";
document.getElementsByTagName('head')[0].appendChild(jq);
// ... give time for script to load, then type (or see below for non wait option)
jQuery.noConflict();
Once you are done with this we can take advantage of the JQuery and get the list of labels
Now what I am doing will work for the Blogger Theme Notable and newly added Theme for blogger.
Normally in these themes you will see Labels in the rights side toogle menu of the page.
So What you need it Click on the Label and Click on Show more.
Now Open Browser Debugging console and declare and variable.
var str = "";
Now run the two codes below
1. $('.first-items .label-name').each(function(){str = str + ", "+($(this).text())})
2. $('.remaining-items .label-name').each(function(){str = str + ", "+($(this).text())})
3. str
all the labels you will be get in comma(;) separated format.

I need to create a link for a set of documents. They are created dynamically, thus the names are also different, f.ex. Test, Test2, so one.
I need to show the link like "Document TestN", where links changed according to the current document. I can now create the links by a href="id" onklick=bla+bla+bla", but the name does not change. Instead of 'Dashboard' I need to get 'Dashboard of "ConcreteSite"', where I can get names by pageHeader:
document.getElementById("pageHeading").appendChild(pageHeading);
<script language="javascript" type="text/javascript">
var siteNameAsParam = window.location.search;
var scrt_var = siteNameAsParam.split("siteName=")[1];
</script>
<p>You are here: Dashboard </p>
Based on your code I think this is what you're after but more detail on what you're trying to do would be great.
<p>You are here: Dashboard </p>
<p>You are here: Dashboard </p>
<script>
document.addEventListener('DOMContentLoaded', function(event) {
var links = document.getElementsByTagName("a");
for (i = 0; i < links.length; i++) {
var siteNameAsParam = window.location.search;
var scrt_var = siteNameAsParam.split("siteName=")[1];
links[i].href = links[i].href + '?siteName=' + scrt_var;
links[i].innerText += ' fred';
}
}, false);
</script>
This does the following:
On page load gets all links on the page
loops through the links and grabs the query strings from the url
splits the query string on siteName
sets each link url to add the query string
updates the links text to append the query string (or undefined if it doesn't exist (see note below)
Note: your code implies you already have a query string in the url of siteName=SITENAMEHERE. Also, depending what you're trying to achieve, there are probably much better approaches. This I hope answers your current question but I think you should review how other achieve what you're after.
Update:
Here is a jsfiddle with a different working sample of what I think you might want. Hopefully it helps. there are comments in the fiddle. I think you want to try doing more when the link is created (set the event listener there, update the text as desired, etc.) instead of on the click event.
I've the following question, let say we have a div like this:
These are dynamically formatted divs, with the classes 'row', 'element' and 'isotope-item' are always present. Everything in between can vary per div.
What I want is to the following:
As you see the commmas are no longer there and seperate classes between the commas are now one class.
Anyone any idea?
I already have the following to remove the commas:
$('div.element').each(function () {
var _sCurrClasses = jQuery(this).attr('class');
jQuery(this).attr('class', _sCurrClasses.replace(/,/g, ' '));
});
I would advise doing this backend,but in JavaScript you could:
This will not account for the space in the words though.
You would need to pass then trough separately one by one and replace.
or store them in a data-attribute and format when you need them.
<string>
var classesFormat = classes.replace(/,/g, '');
var classesList = classesFormat.split(" ");
for(String c : classesList)
{
$("#id").addClass(c);
}
</string>
So you could create a data-attribute for each one instead.
Go through each one, format and the add to class.
<div data-id="Microsoft Office," class="test test test">
With the script
$(this).attr("data-id") // will return the string "Microsoft Office,"
or .data() (if you use newer jQuery >= 1.4.3)
$(this).data("id") // will return the Microsoft Office,
And then do your replace after that and addClass.
I don't think classes work like you think they do
the first PICTURE you posted would result in that div having the follwing classes
row
element
Microsoft
Office,
My
SQL,
Page
Rank
isotope-item
Note the , is PART of the class
You want, according to the second PICTURE
row
element
MicrosoftOffice
MySQL
Page
Rank
isotope-item
Removing , is just as you posted ... the problem is, how do you determine which spaces to remove, and which to keep?

Hi I'm using a CMS which dynamically creates textareas on product pages of an ecommerce site. The text area has a different ID on each different product page. I am in need of some javascript that will check if all textareas on a page are empty and if so display a warning message. I cant assign an id to the text areas so cant use this script I normally use. Any help is much appreciated!
function validate() {
var val = document.getElementById('textarea').value;
if (/^\s*$/g.test(val)) {
alert('Wrong content!');
}
}
Hey Benjamin thanks for your reply, I couldn't get the code working in comments, thinking I'm having a bad day. So as i was trying to say I'm not the greatest at Javascript (but eager to learn!) I've added this to my page but it doesn't appear to work:
<script>
var areas = document.getElementsByTagName("textarea");
// now iterate them for
(var i=0;i<areas.length;i++){
var val = areas[i].value;
if (/^\s*$/g.test(val)) {
// whatever
}
} </script>
With this as in the body
<div class="description">Further Details <br>
<textarea id="catProdInstructions_6486638" class="productTextarea"></textarea>
</div>
Thanks for your time on this :)
You can use getElementsByTagName to fetch all <textarea>s.
It returns a NodeList of all the text areas currently in the page which you can iterate.
var areas = document.getElementsByTagName("textarea");
// now iterate them
for(var i=0;i<areas.length;i++){
var val = areas[i].value;
if (/^\s*$/g.test(val)) {
// whatever
}
}
The NodeList returned is live , this means that it'll update itself automatically as new textarea elements are added dynamically even if you fetch them with ajax or create them with code.
I am using a third party javascript plugin to develop a two-column table functionality as per my requirements. The plugin accepts an input json array which looks something like the following:
var data = {"Project" : [{'Start':'02/20/2012',
'End':'02/20/2012',
'Content':'Project Description',
'Group' : 'Table Group 1'
},...
] };
Group in the above json when used in the plugin can be given any type of content (custom html content as well) which it renders internally as:
var items = []; //json array items will be pushed by items.push from input `data` json
for(var i=0,im = items.length;i<im;i++){
var group = items[i].Group;
groupDiv.innerHtml = group;
}
In my case, to the Group item of the json array item, I am passing a custom HTML which looks like the following:
var customHtml = '<div><span class="button-red"></span>'+
'<div class = "quick-info-hide">' +
'Some Custom Content from input' +
'</div></div>'
I am generating this customHtml from some input (another larger json) and sending it to the plugin and was trying not to modify the plugin itself. However, I had to modify the plugin to add a certain functionality here (row expansion on/off) which is kind of troubling me now.
When the row is not expanded, customHtml's span and div should have class style1, and if it expanded, customHtml's span and div should have class style2.
However, inside the plugin, customHtml is assigned without any if condition of expansion/collapse. Since the plugin was not built with a logic of row expansion/collapse on click, it wasn't expected to do so as well. I want to change the styles here on expansion/collapse to assign to groupDiv.innerHtml i.e customHtml which probably can be done by another variation of customHtml1 which will have different styles.
What is the best approach to do this?
Should I add an if condition here and send two variations of customHtml in the plugin and apply the suitable one on respective if condition? Is there a better method as well in this case to not spoil the generic approach of the plugin (which I seem to be doing here with modification)?
I'm trying to write some code in javascript that uses a user's cookies to display a box containing some information. The page opens with some boxes containing news articles from Google News RSS feeds. I'm using a 3rd party app for the RSS; the feed is included in the HTML code as such:
<script language="JavaScript" src="http://www.feedroll.com/rssviewer/feed2js.php?src=http%3A%2F%2Fnews.google.com%2Fnews%3Fq%3Dbarack%2Bobama%26output%3Drss&num=4&date=y&targ=y&utf=y&css=feed" charset="UTF-8" type="text/javascript"></script>
The user can move the boxes around, and I want to store the box locations using cookies so that if a user revisits the page, the boxes will be in the same location. However, when I try to load the page from the information in the cookies, the boxes are blank. This is an example of what my code looks like (RSS feed for news using keyword "Barack Obama"):
// Render boxes into HTML
function renderItem(container) {
var wrapper = document.getElementById(container);
var div_box = document.createElement('div');
var feed_url = 'http://www.feedroll.com/rssviewer/feed2js.php src=http%3A%2F%2Fnews.google.com%2Fnews%3Fq%3Dbarack%2Bobama%26output%3Drss&num=4&date=y&targ=y&utf=y&css=feed';
var div_box_feed = document.createElement('div');
var feed_script = document.createElement('script');
feed_script.setAttribute('language', 'JavaScript');
feed_script.setAttribute('src', feed_url);
feed_script.setAttribute('charset', 'UTF-8');
feed_script.setAttribute('type', 'text/javascript');
div_box_feed.appendChild(feed_script);
div_box.appendChild(div_box_feed);
wrapper.appendChild(div_box);
}
When the page loads, the box appears but the news articles from the RSS feed are not there and the box is empty. When I look at the source code, however, it is identical to the code of the initial boxes (which did display the news articles).
Does anybody know what's wrong?
Thanks!
You never declared column_div here:
wrapper.appendChild(column_div);
Did you mean:
wrapper.appendChild(div_box);
?
I believe that by default script elements created in this manner have their async attribute set to true, so the rest of your code will execute before your JS has been retrieved.
Where does the column_div variable come from?
You're missing a question mark to separate the post variables from the URL, so the URL is resolving to
var feed_url = 'http://www.feedroll.com/rssviewer/feed2js.php%20src=http%3A%2F%2Fnews.google.com%2Fnews%3Fq%3Dbarack%2Bobama%26output%3Drss&num=4&date=y&targ=y&utf=y&css=feed';
It should be
var feed_url = 'http://www.feedroll.com/rssviewer/feed2js.php?src=http%3A%2F%2Fnews.google.com%2Fnews%3Fq%3Dbarack%2Bobama%26output%3Drss&num=4&date=y&targ=y&utf=y&css=feed'
