Update A Page On Receiving A Message From The Server
Jun 13, 2006
i am trying to put some code within my js such that, when the server
"sends it a message" it refreshes the page. now i have the refresh part
of things. the place where i am stuck is, how can my server (tomcat, am
using a java web app) send a very small piece of info to the js which
when it receives it, refreshes the page.
I've been searching for a few hours and haven't been able to find a code snippet to see if this is available. I'm attempting to pass text from my website to another website that has a form setup on it. I'd like to fill in the pertinent data for my users on the page that I load for them. I cannot make any changes to the receiving page as it is run by another company. I've pasted some of the code that is available on the receiving form.
<script type="text/javascript"> //<![CDATA[ var theForm = document.forms['form1']; if (!theForm) {
Is there any sort of js code that i could put on my website, say on the home page, that when i update the website, it displays that date of when the last update was?
I posted the same post in PHP section but thought might be related to Javascript too. So here goes:
I want to create a decent log at clients side to show alerts from server.
So, server should be able to see a list of connected clients (registered user) on the website, and select a few of them, type something in textbox, clicks send to all of selected clients, and the message is shown in the log at client's website. Also plays a simple sound file when clients receive new message in the log.
Is it somehow possible to setup a backend server to send a message to a client? Or it is a client always have to establish a connection? What I'm trying to code is a simple chat script that sends a message to the client once a member of the chatroom has logged out. The only way that I can make this work is if the client either sends a message (which is a POST call) or when a time delay occurs (I've set a timer to run every 30s after the last GET or POST call). But both of these are basically CLIENT -> SERVER calls. I don't assume that the other way (SERVER -> CLIENT) is possible? no?
I'm trying to implement a simple chatting website. For now what the code does is checking every 10 seconds if there are new posts stored in the database (newer than the last check, 10 seconds ago). Is there a more efficient way than doing this with a timer??? for example, is there some kind of event listener attached to the server that would notify the client whenever the db is updated?
I have very basic javascript skills, just started looking into jQuery and jQueryTools to enhance my websites. I have been coding PHP for about 1.5 years.I have a php form with which users can update their purchase order before making a final confirmation and payment.
Thought it would be nice if, instead of using php for redirecting to a success/fail message in a separate php file and redirecting again back to the form with a 3 second delay, I could get a jQuery script to pop up with a success/fail message, so avoiding all the clumsy php redirecting and page refreshing.I've searched for plugins, but they all act on event listeners attached to a submit button or other clickable html element.Ive searched the net for ages and can't find an easily understood explanation and complete example, where a jQuery pop up notification is displayed in response to a php script executing a db update.
I am making a call to a php file which right at this minute has no validation, all validation is been done by the jquery form plugin. the validation (xss prevention soon to be implemented) in the thanks fails I want to stop the processing of the form i.e. stop the return of success.
I am trying to create a web page in which the contents of one selection list depends upon which element in another selection list is chosen, but where the information to populate the first selection list comves from an SQL database on the web server.
There are a couple of these situations in my application but, for example, the first list might be a list of counties, and the second list a list of states/provinces. Obviously the names of counties depend upon which state/province is chosen, but there are too many possibilities to be able to embed them within the web page itself. So when the user selects a state/province I need to go to the server to ask for the list of counties.
I have seen a number of posts that sort of address this issue. For example it is suggested to use <script src="a URL"/> to ask the server side code to send up data of type "text/javascript". However the examples do not seem to address how the server side code would know which state/province the user had selected.
If there is a web site that addresses this sort of thing, I would appreciate any pointers.
I am currently programming Script Adds data to the database but if i want to Shown the data that have been added Requires refresh the page to show the Data that have been added . and I do not want this method.I want to when adding data to show updates as soon as the addition of data.This can be done by Ajax , and An example of this method used Google Gmail.
if it is possible to check which link on the page receives a focus? For example, i got Links name A1, A2, A3, A4 and A5. How to check which link is currently receiving the focus? is it possible to do?
Before the user can close a page, I would like to have a message come up that asks if this is really what they want to do. the page needs to stay open.
I got this, edited, from msdn function closeIt() { event.returnValue = ""; } <body onbeforeunload="closeIt()" >
It works just fine, too well. I get the message when the user refreshes the page, something I do not want. Any thoughts?
I have a script that parses window.location.hash to figure out which xml file to load. The xml files populate a page on a framed site. The code works correctly to a point.
If I have a seperate html page to support each xml it works. I would like to eliminate the individual html pages becuase only one should be needed.
When I use one page the first link works, then the second one does nothing (doesn't refresh the frame). If I click to a static image for the frame then click the next xml link it works.
What can I do to force the frame to update? I am clicking on a HREF link that should re-load the html page, but with the new xml data.
I am working on a website which has a large image slideshow on top, with the logo. The content articles are in separate HTML files, and are embedded in the main document with a simple PHP include function.
The problem is that clicking on a link causes a refresh of the whole site, the gallery resets to the first image, and there's a momentary flashing of the screen.
I would like to explore the options of having only the main section update (somehow) when the user browses the site, leaving the rest intact, on screen.
I am worried about these potential issues:
- Will it be Search Engine friendly? (i.e. finding and indexing the separate articles)
- The vertical size of the site expands depending on the length of the content. Will this partial refresh be compatible with this?
I followed the video tutorials on this site - pretty good. I'm now able to delete records and remove the tr on he fly. Im also able to insert a new record i my db, i the background. But how do i update my page so the post shows up? Code:
I am trying to send a javascript request from page_1.html to page_2.html, and have page_2.html rewrite the content on page_1.html,
the code I am using to request page_2.html from page_1.html (so the following code is on page_1.html, just to be clear) , this code works fine on other projects.[code]...
I am using this to update the page with new content every 60 seconds
Code:
$(document).ready(function() { var refreshId = setInterval(function() { $('#contents').load('src.php');
[code]...
What I am trying to do is, I want to load the page only if src.php has new contents, I tried this, but now luck
Code:
$(document).ready(function() { var refreshId = setInterval(function() { var current_html = $('#contents').html(); var new_html = $.load('src.php').html();
I am using the following code to show visitors when my page was updated last.
It seems really cumbersome for what it does, too.
Right now, it reads:

I wanted to add code to it so that it reads the hours and is in this format:

How can I add the "at hh:mm am/pm" part? Or is there easier code that will do this?
function getLongDateString() {month = new Array("January","February","March","April","May","June","July","August","September","October","November","December");
when I use Firefox to run my application (this involves sending an IFRAME request to the servlet and handling the response), there is no delay in displaying the data after each response. But when I use IE, there seems to be a 1-2 second delay. The script sends a request using IFrame, goes through a loop to return script tags containing data to the browser, and then data is displayed by the browser and a new request is sent. For IE, when a new request is sent, the delay in receiving the response is quite noticeable.
the second file, soapcall2.html contains just the following (no <html/>,<head/> or <body/> tags)
<script> var ServiceUrl = '/ws/'; var CreateSession = ServiceUrl + 'general.asmx?op=CreateUserSession';
[code]....
In IE 7/8 the error: event is triggered with the correct XML (XMLHttpRequest.responseText) but the textStatus reports parserror and the errorThrown returns [object error]. In firefox it runs without any problems and properly sets the sessiontoken variable.
I've got a page that has a navigation and content div.
The navigation consists of a JS tree menu that has AJAX event handlers associated to all its links so that when the user clicks on any of the links, the content div will update accordingly. The content div is making use of a number of JQueryUI elements such as tabs and accordions among others.
All the JS works fine when I initially open the page; it's only until I click on any navigation link when the problems surface. Once I do none of the JS appears enabled any more in the content div.
I've tried linking to the JS file from the AJAX PHP script called, and that gets the JS to work but only after exhibiting strange behavior - the content div flickers between a JS enabled/disabled state for a few seconds. I figured this may be because the JS file's contents will have been duplicated as it is the same script loaded when initially opening the page.
Is it possible to "Only" display a loading message and hide all page's elements and graphics until the page is fully loaded. then loading message disappear and the content fades in!?[code]...
