i have a table, with records pulled from a mysql database with users who can earn points. is there anyway i could have the points update live, insted of having to refresh the page?
View 1 RepliesI'm using a combination of Yahoo Pipes and rssdisplayer.js [url] to display some snippets from several RSS feeds on a new site I'm building.
The trouble I'm having is that (i) the feeds don't update when I refresh the page, I think because a cached version of the page is being loaded, and (ii) I'd like to have the div containing the feeds auto-refresh at a given time interval.
I've got a Twitter javascript working that does both these things, but can't work out how to get the rssdisplayer.js working this way.
The rssdisplayer code is:
So my problem is that i can't send form data in FF without page refresh (though in IE7-8 everything works smoothly).

I was wondering if anybody could help me out a little. My goal is to
update some information about a system every 2-5 seconds. The
information needs to be displayed in some sort of table, but the size
of the table needs to be able to shrink and grow. The main problem
here is updating the table without refreshing the entire page and
making any clicking noises. I was thinking maybe I can put the table
in an iframe and use javascript somehow to update the iframe whenever
neccesary.
I've 2 little problems in my page....i've already done the functional script in php for erasing and inserting a row into a table...but i've a problem...this row contains 2 links that are for erasing and modifying the row.... it happen that when i insert a row (that has class="edit" and it's for working on ajax...) i can erase and modify only the old rows and not the new ones...probably cause javascript takes all the element of a general class only at the loading of the page and link them to the onclick function....
I post the code here...
The html+php table
And when i insert a row into the db i update the table with this script
Where the data appended to the table is a row of the table given from the php script
Another thing,as you can see, is that i would like to know how to pop up a new alert if data from the last function on the $.post is equal to a string
I tried to do it with the compareto js function but it didn't seem to work....
I am (finally) successfully calling and running a php script using $.ajax() and now I need to update a table row as a result of that. In the ajax I have these variables for the updated row: docID, docName, docDescription. Since the docID is used elsewhere on the page, I'll need to start with the table id, which is #docsTable.
The rows that I need to update look like this:
<tr bgcolor="#EFE5D3" style="font-weight: bold;">
<td width="25px"><a class="docEditLink" name="33" href="#">Edit</a></td>
<td width="20px"><input type="checkbox" name="removeDocs[]" value="33" /></td>
<td>Document Name</td>
<td>Document Description</td></tr>
The name attribute is the docID, so that is unique within that table, for that document. So, my question is, how can I build a selector that will allow me to change the 3rd and 4th <td> tags with document name and document description, respectively?
I'm dynamically outputting the contents of a MySQL table using Python, to a HTML table, which users view (obviously) through a web browser. It looks great, but the problem is that I'd like users to be able to update these values. For example, I have the current value of certain fields in text boxes. I'd like users to be able to change those values, then hit a submit button or similar (ideally on-the-fly) to update the dB. I imagine javascript will need to pass values to a Python script, but I don't know what the best way to go about this is.
# Python code embedded in a .psp file
cursor = db.cursor()
cursor.execute("SELECT from_name, from_address, project, orb_proj, app, tier, environment,

I got this problem with live() event.I have used it as follows.
$(".addressDiv span").live("mouseover", function(){
//clickable function here......
------------------------
});
I have used the live() event to trigger the function on mouseover in the dynamically added elements. But the problem i got is that once the live event is called it takes the class of the element and stores. And when the class of that particular element is changed dynamically the live() event does not detect the new classed added dynamically, instead it takes the former class. Live() event does not update the class.

It works flawlessly on my dev page: http:[url].....But I am having issues with is on my live page: http:[url].....My first thought is that it could be a labeling issue (ie: I forgot to remove "/dev" when moving the HTML over to live) but after reviewing for an hour, I don't believe this is the issue.
Is there a trick (with javascript or something) that can change a hidden value on a page directly from the browser without using "Firebug" software? for example: <input type="hidden" name="something" value="something_else"> I need to change "something_else" to "something_else_2"

i want a value search(find) to database(table), this requires an ajax call to a server page? if want show result search live(online) and search letters to letters (transliteration), how is it?
[Code]...
I have a page, that will contain up to a couple hundred different widgets on it, that an individual will be able to browse through and choose the size and quantity of the ones they want. Each widget will have form fields associated with it: "size" (small, medium, large) and "quantity", with a "total cost" field underneath that. As the individual looks through the widgets, choosing the size and quantity of the ones they want, I'd like for the "total cost" field to be updated under each widget. I'd also like a "total order cost" field that sums up all the costs of the widgets they want.
I need the script to basically say:
If size = small, then multiply $1 by the quantity.
If size = medium, then multiply $2 by the quantity.
If size = large, then multiply $3 by the quantity.
I am new to jQuery. My background is C++ and C#. Once I have the html using selectors and filters is not hard to understand. My problem is understanding how to capture a live html page in jQuery and assign the page to an object which I can then use to extract information using basic selector and filter functions.
View 1 Replies View RelatedI got this code from w3schools and I want to alter it for my needs. However I can not get the basic example to work. I have repeatedly cross checked it and can't see any error. I wonder if anyone can spot what I am doing wrong. code...
View 2 Replies View RelatedI have a web project I've been working on in my free time using mostly jsp. It's currently set up so that if a user clicks the login button it takes them to a check-login servlet which will return whether it's a valid login or not through a session.setAttribute("loginstatus","Valid"). Everytime the check-login completes, though, it redirects back to the index.jsp.
I want it to never leave the index.jsp page, but instead just refresh the main content cell in the table. Is it possible? I've never worked much with ajax or javascript before, but have considerable experience with java
Edit: the reason I post this here instead of JSP is because I think it may require javascript or some dynamic coding of some sort

when i load page it does nothing only blank page, may have code in wrong place but not sure so can someone show me a working example so i can find out what i'm doing wrong also i would like the part of page to refresh evey 120 seconds is this possibe with jquery?
My background is C++ and C#. Using basic selectors and filters in jQuery is not a problem for me. My problem is finding the right jQuery code to capture a live html page and assign an object which contains all the html text I just captured... then I can use the object to apply basic selector and filter functions to create another page.
View 6 Replies View RelatedBasically I have site that uses iframes to load its content. In one of the frames I have an html page that contains an image, and when you mouse over the image it is supposed to fade up a little description box. Naturally when you move the mouse away, the box disappears. I have a javascript function that fades the image up and down, and it's activated via an onmouseover event that is attached to a div that contains no content, but lays over the image to define the triggering area.
I use Dreamweaver to preview my pages while they are stored on my computer, and everything works beautifully. However, once I upload the page to my site, that functionality disappears completely. Code:
Many ajax and javascript functions change the innerHTML of elements in the source, writing and rewriting things in the source
You can run any javascript function or action you want that would change the source, but when you view it, it will always show the original source before a JS function changed it
Is there a way to view the changed source after each time a JS functoin changes it??
for example:
<span id="whatever">This is the original source code</span>
then you may run this piece of JS:
whatever.innerHTML= 'Changed source code!'
but when you right click and press 'view source"
you will always get this:
<span id="whatever">This is the original source code</span>
I want to get the changed source code, maybe its possible to write the changed source code to another file, or use some kind of HTTP prog to read the changes on an html page?
I'm working on a project which requires a small portion from a large table of information to be displayed on a webpage (sort of like a magnifying glass). The display will be a table of fixed size (m by n cells). Some of the cells will be merged. When the table updates, different sets of cells may be merged.
It needs to be coded in HTML5, which I assume includes the use of JavaScript and CSS (The specs of this is rather unclear at the moment, so I'm going to cover all bases).
Anyhow, looking through the HTML5 and JavaScript tutorials, I found two ways to solve this problem. One way would be to have a script to parse out the relevant information, and have it output into a table (dynamically generating the HTML required).
The second way would be to have the script draw the table on its own in a canvas.
User events (such as arrow keys on the keyboard) will change the position of the focus (move the magnifying glass in a cardinal direction).
I hit a small snag with the first solution - Is it possible to update the table on the page (including changing the structure of it) without having to refresh?
I have been trying to figure out how to go about making a table of comments auto-refresh when someone inserts from a comment form without refreshing the whole page.I've tried looking into AJAX for this, but everything I have looked at, in terms of tutorials, just flies right over my head, and I can't really make much sense of it.
