Displaying Content Based Upon Internet Connectivity
Aug 13, 2010
I have a site that can be downloaded and run on a closed network (not needing an active Internet connection). I'd like a page that displays live data to a user with Internet connectivity (I can do this) but display "canned" data when the user is without an internet connection...and this difference in page display is transparent to the user. I know this can be done with php but the user without Internet connectivity will likely not be able to run php locally so the page must be an .htm file. I there a javascript somewhere that does this?
I work for masterclock. We sell network synced clocks and timing systems. One of our products is a "bell ringer." We currently control this ringer through a C++ program another one of our employees made. However, it only works on Windows systems, looks like crap, and is as confusing beyond all get-out. I have been given the task of rewriting this program in a pretty, easy, and universal format. i.e. a browser. Now to further explain the bell system program.
1. The program searches the local network for the bell system hardware. 2. User chooses appropriate hardware (if more than one bell system exists) to connect to and enters the password. 3. User edits tables stored in a local MS Access database via the bell system program UI. 4. User sends data to the bell system hardware it is connected to.
I've been racking my brain and the internet for about 6 hours trying to see what is possible. Because this all needs to be done locally I can't use any sort of server-side language like php or asp. It seems silly to make a client install a virtual server to connect to a file that is on their own computer. I'm assuming that I am pretty much limited me to javascript. I found this site but that only works with internet explorer which is almost as restricting as the program we have now.
I considered flash for a little while until I found out a swf can't connect to a database w/o using php or asp. We aren't limited to the MS Access database but it would be less work for me if we could stick with it. It may not even be possible but it seems like it should work. some way. We also considered an internal site on the bell ringer hardware itself, like routers nowadays. I think that would be an equally if not more difficult process though and I'm limited to about 500kb on its flash memory.
I'm using javascript in addition to a web service (BTBuckets) to display different content to visitors based on actions they take on my site. The javascript is working fine, but I noticed that if I simulate BTBuckets being disabled using Firefox Adblock none of the content shows up. So in the off chance of the service going offline it'll leave some pretty funky holes in the my content. I tried <noscript> tags which works with javascript off, but the content is still blank when I disable BTBuckets. I'm wondering if there's a way to display the default content if the service is unavailable?
Here's the code I'm using: In the head: <script type="text/javascript"> //<![CDATA[[ $BTB={s:XXXXX}; $BTB.jsh="[URL]"; //]]> </script> <script type="text/javascript"> document.write(unescape("%3Cscript src='" + $BTB.jsh.replace(/(https?:)/i,document.location.protocol) + "' type='text/javascript'%3E%3C/script%3E")); </script>
The code in the body used to replace an image depending on visitor behavior: <script type="text/javascript"> var _t = ""; if ($BTB.clusters["ppc_visitors"]) { _t = ""images/top-photo-tracking-number.jpg" alt="Call Toll-Free: 1-800-XXX-XXXX">"; } else { _t = ""images/top-photo.jpg" alt="Call Toll-Free: 1-800-XXX-XXXX">"; } document.write('<img src= ' + _t ); </script> <noscript><img src="images/top-photo.jpg" alt="Call Toll-Free: 1-800-XXX-XXXX"></noscript>
What I want to do is have a page that only displays if javascript is enabled(or similar) in the sense that it tells users that js is not enabled and how to enable, what were doing is creating web forms and would only like them viewable if js is enabled so that we can validate client side and reduce server load. Main reason is validation client side, cause if the initial form works well we will expand it to include forms for every type of job we can. No idea to where to start as js is not a strong point.
I have a page where I need to display 1 of 5 divs, based on the radio button that's selected. The code I'm using is from a previous page that basically did the same thing, only the user had to click on a tab, which would in turn change the style on the div from "display: none" to "". I'm assuming I can basically use the same code, but I'm not sure how to do this with radio buttons. The page I'm working with is at [URL].
Here is the code: Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "[URL]"> <html xmlns="[URL]"> <head> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" /> <title>Untitled Document</title> <style type="text/css"> .....
I am trying to display three different types of forms of the same page. One of the three will appear based on the selection. Right now my code has everything shown when you first reload the page and then when you select something it all disappears and nothing comes back. I am trying to use divs because the forms will perform the same action just with different parameters. It is a lot of code but the forms are the same thing just wrapped in a different div and I know they work. hopefully this will cut down on the amount of time you have to look at it.
Below is what I have so far: Code: <html> <head> <script type="text/javascript" language="javascript"> function choose() { document.getElementById('notes').style.display = 'none'; document.getElementById('tests').style.display = 'none'; document.getElementById('homework').style.display = 'none'; .....
I have a form with a drop down list box, few textboxes with labels and submit button. depending upon my selection I should be able to show hide textbox; assume items, 1,3,5 in the selection box shows the items other than the listbox and 2,4,6 items in the selction box if selected hides the labels and textboxes. but in all the case submit button should be present.
You've all seen it before banner codes/rss feed displayers/twitter feeds/etc. All you do is copy and paste a <script src="[URL]"></script> somewhere on your website and it retrieves the html from the remote server and displays it on your site. I have a back end php page that pulls the required information from my DB based off a userid passed to it i.e.: mywebserver.com/display.php?id=xxxx Is the javascript just a simple ajax call to my php page passing straight on the userid passed to it or is there something more complex to it? I was always under the impression you couldn't do remote ajax calls to a page on a different server, which if I get this right a script off my server included on another domain becomes a member script of that domain and not my own?
I have content inside a DIV that I want to display only the first time the page is viewed. I'm assuming this can be done with a cookie and javascript with little difficulty.
So basically it needs to write the cookie and the code for the DIV on the first load and then anytime that person returns to the page, the source for the div is omitted.
I've been researching this for a while but just am not getting anywhere.
get the information selected from the drop down boxes in my form to display in a pop up. The text field and text area information diplays fine. Can anyone tell me why this isnt working?
JavaScript....
<SCRIPT LANGUAGE="JavaScript"> <!-- Begin function displayHTML(form) {
I'm fairly new to JQuery and am trying to get my menus to load all the images before it tries to fade in. I am passing categoryid to an external php page which gets the relevant data from the database, and then displays it in the right div element.
This pops up a divs with a black alpha background, so that it appears the new content is displaying over the top of the current content. This all works fine, however the content I am displaying in the top level div is (or should be) dynamic.In order for the content to be useful I need to grab the id.Normally I would simply do this:
I'd like to put a script on the home page of one of my sites that automatically rotates content for a specific day of the week.
You can see the site HERE.
I'd like to take the first story in the NEWS & EVENTS section and make it change with each day of the week to match the corresponding stories in THIS PAGE.
I'd like to do this all with Javascript rather than server-side includes. Unfortunately, I know very little Javascript.
I have a simple script for showing my content (pictures) on other websites, but it generates the content by reading the users date (1-31), and because of that can show only certain amount of content/pictures (31) on a mountly bases. Can I edit this simple script to randomize the way the content is being displayed, so I'll be able to display a greater number of content? Example of the way the content is displayed: [URL]
Code that displays the script: Code: <script language="JavaScript" src="[URL]"></script> Script:
Code: var msg = new Array(); Stamp = new Date(); today = Stamp.getDate(); .....
function writeTip() { document.write(msg[today]); } document.write(msg[today]); document.write('<br>[<a <a target=_blank href="[URL]</a>]');
1) I have a series of divs embedded into a page, sort of like an FAQ setup. Each has a unique id like id="service1" etc.
2) i'm using an unordered list with each li being a hyperlink to the div id's
3) the div's are set up as name anchors ( <a name="service1">Service One</a. ) so I can hyperlink to them via the <a href="#service1">Service One</a> method
4) There's 22 divs and they need to be hidden until summoned. Therefore, I set $('.service').hide(); to make them all disappear.
Now, where i'm stuck is in how to summon them individually and have them appear when the appropriate list hyperlink is clicked. I'm using:
$('.servicelist a').click(function() { var toLoad = $(this).attr('href'); }
So it's telling it to load the info found at the appropriate link. This is where i'm stuck. I need help on
1) how to 'unhide' the proper div id containing the related data
2) how to point it to the right location in the page (target div)
I have enabled a hover() event on a DIV that includes an H2 element that is always displayed and a child DIV that needs to be shown/hidden. This code works wonderfully on Firefox and IE. However, it's not working in Safari (I have not tested Opera or Chrome yet)Here's my (very simple) code:
I'm new to javascript and still trying to learn my way around. Below is my code
<script type ="text/javascript"> var a1 = "2"; var t2 = "hello world"; var total = ("t" + a1); alert(total); </script>
That code will display the string "t2" rather than the value of the variable t2. How do I make javascript display the value of the variable rather than the string?
I'm using the script below in a custom HTML to generate a random line of text (not with the text shown here). This works fine BUT; I want it to go randomly through the WHOLE list without repeating lines that already have been printed. As it is now, a line of text might be printed several times in a row, which is a little annoying. I'm using a refresh button for generating a new line of text.
How can I just make it display in the order shown and just re-arrange the content so it seems random to the user? Random would the best though...
<script language="JavaScript"> <!-- var r_text = new Array (); r_text[0] = "All the leaves are brown";
The content of my webpage is all contained in hidden divs. These divs are shown when a link in the nav bar is clicked. At the moment, ALL divs are hidden on page load, only the nav bar is visible. Is there a way to have one of the divs visable when the page loads? i.e the 'home' page.
function init(){ if(document.getElementById && document.createTextNode){ var mn=document.getElementById('nav'); var as=mn.getElementsByTagName('a'); for (var i=0;i<as.length;i++){ as[i]. false} as[i]. false} } hidem(); }}
function show(l){ hidem(); var id=l.href.match(/#(w.+)/)[1]; document.getElementById(id).style.display='block' }
function hidem(){ for (var i=0;i<document.getElementsByTagName('div').length;i++){ document.getElementsByTagName('div')[i].style.display='none' }}
I have successfully loaded an element of content from another section of our website on a page, but for some reason it is firing .load() twice and displaying the section of content twice, stacked on top of each other.
i have managed to make things work how i wanted quite quickly but to be honest jQuery is so easy that i'm not sure i completely understood what i was doing .. but it's working anyways ... well almost ...I have an empty div into which i load HTML content from another page. When i click a link on the page, the content from the other page should load and then the div should change background color and then be displayed with a fade animation. When i click on another link, the displayed content should fade out and the new content fade in.Everything works more or less only that when i switch from one loaded content to another, i can briefly see the old content before the new one is displayed, so the DIV fades out, then fades in again with the old content loaded and then only the new content switches in.I think probably i have my code wrong, could someone have a look ?
$(document).ready(function() { var href = $('.bodytext a').each(function(){ var href = $(this).attr('href');
I'm making a quick and dirty Google Calendar displayer with help from Full Calendar and am struggling to display the details of each Google event correctly. As you may know, if you're not logged into Google Calendar, if you're given an event link or invitation you will be taken to a dynamically generated page displaying the basic details of that event. It includes a <link> ed stylesheet and inline style="..." for each element. I have attached a screenshot of a typical event page.
I'm trying to strip out all the style and just display the content:
eventClick: function(event) { if (event.url) { $("#details").hide().load(event.url); $("#details *").each(function(){
I have Win 7, IE9. I have a HTML file on my hard drive, with Javascript within. When I load the page, it keeps popping up Do u want to allow this content, I have to click to allow. I want to stop this, and after doing some searching I found the setting in Internet Options, Advanced - "Allow active content to run in files on my computer".
Perfect.
Doesnt work. When i check this box, the page loads without the warning, but then the Javascript just doesnt work.
Getting quite annoying, because this file is my home page.
