JavaScript - Mini-blog/twitter Style Website Js + Xml
As part of course work for class I must write JavaScript/XML (with CSS) to carry out the following tasks. In essence it is a micro version of twitter. Users must be able to login, make posts, edit them.
A text box should appear, with reset/update buttons. When the Update button is clicked the following occurs: 1. The user name is added to the message text typed by the user 2. A time stamp is added after the message text 3. A photo is added at the left 4. Any URLs are made into hyperlinks 5. The combined photo and text, formatted suitably, is prepended to the list of previous messages below the input area, i.e. the most recent item is at the top of the places visited. 6. The message box is cleared to allow further user input. - When the Clear button is clicked the text area is cleared. Additionally 1. Using a manually created XML file users must be able to "register themselves" 2. Posts must be manually saved in an XML file which loads upon login 3. When anyone opens the default page they are presented with a list of all your journey and comments (retrieved from the server). 4. Allow a registered user who has logged in to add, delete or modify only their comments. 5. Use one or more XML files to record registered users and passwords as well as posts and comments. These are manually created in 1& 2 above. ---- I initally tackled the first section using innerHTML and other various Javascript components but am at a total loss as to how to achieve the same thing using nodes (and XML). Any help with regards with where to begin would be much appreciated.

Hi All, I am trying to create a website and am having problems editing a piece of code. A working example can be seen Here The only problem is that the "pages" are open when a user arrives on the site and I want them to be " closed" until a user clicks them, much like the "Search, Profile & Draw" tabs. I have included all the coding used to this, the only thing I haven't included are the images. Anyone got any idea how this is possible? Regards Jake Hi all, I have just joined this forum hoping for some help on a problem i am having, i have a feeling the solution is simple but im a noob at JAVA so i have no idea how to work it out. The site is.... http://inspirecalendar.net/html/purchase.html The problem is the following.... When you select US (West Coast) as your location it doesn't update the price on the right properly. If you select it first it just won't display anything. if you select it after choosing another one and hitting continue then it doesn't change. Any help would be appreciated, hope i explain the problem properly if you have any questions feel free to ask... Thnks in advance :Smiley I am looking for help to develop a java code for my e-commerce site mini cart. I have looked locally (kijiji) and on Coding Forums market place and haven't received a great response. Either the person had other projects they were working on or they were trying to "sell" me more than what I was asking for (ie web and graphic design). I have a mini cart on my site that I would like to have a few specific features. I am hoping someone in this forum can help me out (as I have received wonderful help before!!) I need a javascript code/feature that will: - highlight the most recent item that has been added to slide down mini cart window - refresh the mini cart div content to update item count and price. On the site I am hosted on there is a built in feature to show how many items are in the cart and total price, but I don't know how to get it to update successfully - when slide down mini cart window refreshes it should'nt scroll to the top (if there is a scrollbar) ie: looking to implement a javascript: void (0) if possible - have the slide down minicart window appear for 5-10 seconds then automatically slide back up. (the visitor can also have the option to close the window before the 5 seconds) I would really appreciate any help with this. I find javascript hard and I have tried to learn it, but unfortunately I can't seem to grasp it . Hi to every one. I'w created a mini javascript game for my site where you click on red button as fastest as you can for 10 seonds to achieve as best as you can click numbers per second. And the end score is a variable which I send to a function which reads the array that contains ten best scores and write your score in same array if it's among 10 best. Now I want to make somehow to save that array on server so I could read it on page load to show a high score list, but I'm having trouble to write that array in any kind of data on server that I could read it again from same data. I would be very grateful if someone can help me! Hi Everyone, Has anyone noticed the twitter confirmation box (when you hit save in Settings, the page refreshes and a white confitmation box appears along the top of the screen and disappears again in a few seconds)? Does anyone know how to go about implementing this? My JS skills would not be the best. I wonder is there a jquery plugin that I could use or similar? Thanks in advance, Brian if I have an html page that uses the <style> or a <link> to call a style sheet these properties aren't available to JavaScript is there a good way to access them? eg Code: <html>
<head>
<title>expandable text area</title>
<style type="text/css">
#expandable{
height: 100px;
}
</style>
</head>
<body>
<form>
<textarea id="expandable" cols="30" rows="10"></textarea>
</form>
</body>
<script type="text/javascript">
document.getElementById('expandable').addEventListener('click',function(){
if(!this.style.height){
this.style.height = this.scrollHeight+'px';
}
alert(this.style.height);
}, true);
</script>
</html>
In this example I have the height set but I cannot access it since it is not declared in the style attribute of the html element Hello, I have this working js twitter feed on my site, but I am trying to generate the topsy retweet button through the .js file via an innerHTML call, but its not working. the innerHTML works if I put test or something in there, so there is something within this line of code that is breaking it. Code: document.getElementById('retweet-button').innerHTML = '<div class="topsy_widget_data"><!--{"url":"'+url+'","title":"inConcert Web Solutions, Inc."}--></div>';
This is the entire script, I really appreciate any help Code: //Twitter

I have a twitter feed on my site and although am generally happy with it, the time-stamp for each tweet is several hours ahead of my time zone. I've looked through the js files to see if there is anything that allows me to set the timezone but cannot find anything. Anyone know how to reset the time to pacific standard time? Here's the URL http://www.kitchenprose.com/gmtest/index.html Can't for the life of me see anything in the code that controls time zone (would like Pacific Standard time, US) Code: $(document).ready(function() {

Many thanks! Ok so I'm making a music website for a project and we have the official Twitter widget in the sidebar. It is an external javascript file as the website must be XHTML 1.0 compliant. What I'm trying to do is make this dynamic so that when viewing different artist pages, the widget changes to that artist's Twitter Feed. I have gotten this to work when the script was fully on the page, by echoing a PHP variable in the javascript, but when it's external I can't figure it out. The file MUST be external so that it passes the XHTML 1.0 Validator. Here's the widgets code(significantly shortened, the full code is too long to post here): Code: new TWTR.Widget({
version: 2,
type: 'profile',
rpp: 4,
interval: 6000,
width: 'auto',
height: 300,
theme: {
shell: {
background: '#000000',
color: '#ffffff'
},
tweets: {
background: '#000000',
color: '#ffffff',
links: '#ff5454'
}
},
features: {
scrollbar: false,
loop: false,
live: false,
hashtags: true,
timestamp: true,
avatars: false,
behavior: 'all'
}
}).render().setUser('choiceprize').start();
All we need is to pass a string to the .setUser('choiceprize') here ^ so that instead of 'choiceprize' it is our variable. Any help is appreciated! So, say I want to grab two twitter feeds from 2 people and put them together in one feed on a page (not using the built in twitter 'goodies'). How can I do this? I'm sure it's possible...
Hey, I'm struggling to add twitter links using the current method I'm trying and I really need some help from someone with more knowledge than I. So here's the current attempt and along side is a working function that returns the html sent to it back with the links working. Code:
var ADD_tweeter=function(tweet){ var html="";var T=tweet.split(" ");for(i=0;i<T.length;i++){ if(T[i].indexOf("@")===0){ var stripped=T[i].replace("@","") , tweeter=T[i].replace(T[i], "<a href='http://twitter.com/"+stripped+"'>@"+stripped+"</a>"); T[i]=tweeter}};
for (i in T){html+=T[i]+" "} return html }
var ADD_links= function(txt){ var Txt=txt.replace(/((http|https|ftp):\/\/(([A-Z0-9][A-Z0-9_-]*)(\.[A-Z0-9][A-Z0-9_-]*)+)(\/*)(:(\d+))?([A-Z0-9_\/.?~-]*))/gi, '<a href="$1" target="_blank">$1</a>'); return Txt}
I need to devise a way to pick through and change the @twitternames to links. I thought I had it, but when I combined the actions into the script (it's a search engine for twitter subjects) ,the links get the right html, but I can't find a way to make the twitter links work correctly. I tried to follow the same formula as the working function ADD_links, but I just can't seem to understand the notation or something. Also, is $1 part of Regex? And $2? I saw several scripts that were for doing what I want to do , but they all seemed to be php scripts and I couldn't adapt any of them despite countless hours trying. Here's a link to the working page http://www.hardwoodfloorspdx.com/misc/twittersearch/ The page is pretty large so I didn't want to post the entire thing. Any help will be greatly appreciated.

Many thanks! Hello, first time poster here. I have very little understanding of Javascript and have a problem with some I'm using. It's a singleline twitter feed and you can see it top right he http://zest.explosiveapps.com/navigation.php Code: // Compatability with jQuery:
jQuery.noConflict();
window.$ = function (element) {
return document.getElementById(element);
};
/* Header and footer JavaScript */
jQuery(document).ready(function() {
var $ = jQuery;
function scroll_tweet(li){
var post = li.children("div.post"),
pWidth = post.width();
if (pWidth > parseInt(balloon.css('width'))){
var leftEnd = li.find('div.end');
if(leftEnd.length === 0){
leftEnd = $('<div class="end left" />').appendTo(li);
}
var offsX = parseInt(leftEnd.width());
post.animate({left: offsX - pWidth - 55}, 23000, 'linear', function(){post.css('left', offsX);});
}
}
function swap_tweets(current_tweet){
var next_tweet = (current_tweet + 1) % 5; /* max five tweets */
var li = $("li#tweet" + next_tweet);
$("#tweet" + current_tweet).fadeOut(300);
setTimeout(function(){
li.fadeIn(400);
}, 400);
setTimeout(function(){scroll_tweet(li);}, 3800);
display_tweet = next_tweet;
setTimeout(function(){swap_tweets(display_tweet);}, 11300);
}
var balloon = $("#twitterpost div.balloon");
display_tweet = 0;
if($("div.balloon ul li#tweet1").html() !== null){
setTimeout(function(){swap_tweets(display_tweet);}, 12000);
var firstli = $("li#tweet0");
setTimeout(function(){scroll_tweet(firstli);}, 7500);
}
});
As you can see from just watching, it has some problems. It doesn't fade out posts before displaying a new one. From what I understand it talks to the CSS to figure out the length. So maybe that's where the problem is. Code: /* twitter-bubble */
#navigation #twitterpost {
position: relative;
top: -33px;
right: 95px;
}
#navigation #twitterpost .balloon {
position: relative;
float: right;
width: 345px;
height: 21px;
overflow: hidden;
margin-top: 0px;
padding: 0;
background: url(/navigation/images/bubble.png) 0 0 no-repeat;
font-family: "Lucida Grande", "Lucida Sans Unicode", Arial, Verdana, sans-serif;
}
#navigation #twitterpost .balloon div {
font-family: "Lucida Grande", "Lucida Sans Unicode", Arial, Verdana, sans-serif;
color: #666666;
padding: 0px 0px 12px 10px;

#navigation #twitterpost .end {

Thanks in advance I am wanting to allow a user to update their twitter status from my website. I was planning on using Twitter's @anywhere feature, but this was not a very friendly solution: Take over 3 seconds to load Makes 14 requests Calls jQuery twice Then I found the Twitter REST API: https://dev.twitter.com/docs/api Using OAuth, I want the user to be able to login, and then update their status using that API. I've been trying to find tutorials on this, but I haven't found any that use the REST API to update the Twitter Status. Does anyone have code for/know of a tutorial for what I'm looking for? Hi I'm looking for a simple ticker that scrolls horizontally across the top of the homepage of a site I'm working on. Ideally I would like one for both Twitter and RSS feeds, but either is good. If anyone knows where I can find one that's simple to implement that would be great. Kind Regards |
