I have a web page that displays records from a database. I want to
allow the user to specify his own "page size" - that is, the number of
records to be displayed on a given page. I have a place set up for him
to enter a value and save it to a cookie. My problem is, I can't
figure out a good, simple way to pass that value back to the server.
The page is accessed in various ways: it's first viewed by selecting
it from a javascript menu. Then the page itself contains a form with a
series of buttons that allow the user to jump to a specific page above
or below the current page. There are also "sort links" at the top of
the columns of data which refresh the data sorted in a different way.
In all of these cases, I will need to pass the page size back to the
server.
I tried storing the page size in a hidden input field. This works but
it's not available on the first request (from the menu). I thought
about passing in the value as a query string (mypage.htm?PS=123) but I
can't figure out how to attach the value to all of the various
requests (menu, form and links).
how do i pass values back to javascript from the server via ajax? I don't want to pass entire html. Is there any way to simply pass a JavaScript object or an array without stuff like xml and json? I could probably do an eval() on the result to convert it to a javascript understandable array, but maybe there's a more clever way to do that?
I have a problem with writing cookie from Jacascript. My problem is that I have two server, one is A, and the other is B.
(1) I call a aaa.html from A. In aaa.html : ... <iframe id="frame1" src='http://B/bbb.html'></iframe> ... (2) In bbb.html : document.cookie="key=123"; alert(document.cookie);
I fail to write key=123 to cookie. Is this because of different ip? Is there any other way to write cookie?
I have an external javascript sheet with an array of images w/text and the following code:
var current = 0; function update() { var pic = slides[current];[code]....
When the user clicks the link, it should open the page to the slideshow and it should start on slide[8]. I think what I need to do is pass the value of the cookie to the variable "current", but I don't know how to do that. Also, I only need the cookie to last long enough for the new page to load (about 20 seconds), but all of the cookie scripts I've found set expiration in days.
New to the forums so nice to meet you all... I have an asp.net app that is written in C#. The app connects to a webpage, logs in and pulls some data down from a site (all server side). After the initial log in I am storing the cookie and passing it on subsequent requests. I would like to provide functionality that will log end-users into the 3rd party website and redirect their browser (_blank) to a particular webpage. Is it possible to pass the cookie collection from asp.net to javascript and have javascript do the browser _blank redirect?
i have a client php file and a server side running only php file the client.php and server.php are 'connected' through javascript and flash in client.php. so server.php runs in the background of client.php
now i want to pass the cookie from client.php to server.php through ajax the ajax in client.php:
Code:
<script type="text/javascript"> var cookie_value = $.cookie(id); $.ajax({ url: "server.php",
I have created an entry form that I display in a modal dialog. I have two buttons on the form: "Add and close", and "Add and allow me to add another". However the only time my modal form will post back to the server is after the form has been closed. I want to do the following: The user opens the form in a modal dialog. The user enters data, and clicks the "Add and allow me to add another" button. The page sends the user input to the server, which adds the input to a database and updates a datagrid on the page. This updated datagrid is visible behind the modal form, so the user can see it happening in the background The form clears all input fields and the user goes again. Any code I write that calls the server (button click events, ajax calls, etc) are ignored, unless the modal form has been closed.
I have these two functions below and when i try to change the back url string value on the main server to check_out.php like it is on the dev. environment nothing happens. It keeps going back to the myaccount.php. It works fine on the development environment.
function stateChanged() { if (xmlHttp.readyState==4 || xmlHttp.readyState=="complete")[code]....
I'm spawning a child window from a parent. In the child I'm dynamically building a table. When I click "finished" I want the entire table to go back to the parent and replace the original table "shell" (an empty <table> </table> tag-pair).
Note: The table ID is the same at the parent and child. This allows the replacement to work repeatedly. The child window closes but I don't see the table on the parent.
I get the feeling I'm mixing DHTML and DOM (ie "window.opener....") and .. well, I don't know what to think.
Is it OK to nest DOM functions as shown in the code?
I've tried a couple of different things - I'd like to use "replaceNode", but the syntax is not clear in the reference I have.
[b]The problem{/b] Below is the function triggered by the child window "finished" button's onclick event.
I suspect the variable assignment is wrong as an alert box immediately after it (removed in this sample) did not show up.
function finished() { var oldReport = window.opener.document.getElementbyId('DBReportsTable'); oldReport.firstChild.removeNode(true); // the <tbody> oldReport.appendChild(document.getElementById('DBReportsTable').firstChild); window.close(); return true; } // finished()
I'm using a geolocator service to find the zipcode of a web page visitor using the code below. This will be used to serve up ads to the visitor based on their zip code. The question is, how do I pass the zip code value from the script into an ASP variable, such as a cookie or session object?
I am using PlainAjax. [URL] Here is my code and it is not working if i called from Javascript function.

But i am not able to get any value in my php program. or is anyother way to pass the variable from Javascript (except pass thru url query string, this is not secure)
I know at this point is that these is a difference in the array formatting between PHP and JS. The magic bullet is supposed to be json. However, this code does not work as advertised.
[Code]...
The variable $prt is list of associative arrays, so to get a value in a particular row manually , $prt[0]['location'] should give me the value for location in the first row of output. All of this works just fine if i hard code this in html and php. However, I want to dynamically produce the rows as needed which requires that a loop employed. The application also requires that the user may add a row which also need to be accounted for when posting.
I think the best solution is to make this a totally javascript entity. All I need to do is to be able to pass in the server side data. Calling JS from PHP does not work, although i have found many places where they show basically the same code , claiming that it works. think json needs a bit of tweaking to make this happen, but i'm not sure how to proceed.
how to pass javascript variable values to server side code i used a hidden field and passed he value in it . i do get the value in hidden field but on using request("hdfield") its blank how do i get the value frm javascript
I am trying to pass an argument to a function to process server responses. My original line of code looked like this: [url]
This works well enough as is, but I am trying to pass arguments to the function, and everything I am reading says to contruct the code like this: [url]
Every example I have come across uses this same approach, but I keep getting the error "Expected ';'" pointing to this line and then the code fails to execute. I just cannot see where there is anything missing, and it looks pretty much identical to my examples.
I have also tried replacing the call to the function with the actual code in long-form, and the result is the same.
I'm trying to create a simple checkout system that utilizes cookies to pass information from page to page. Currently, my entire script works fine except for the read cookie portion. I cannot figure out what is wrong with it. It has been validated and the syntax is fine; it just doesn't work. I use the function with the onload call on my html file such as:
Can I make a list of hyperlinks that users can customize and save as a cookie by clicking a button and automatically retrieve the cookie so it remembers their list next time? This is kind of what I want to do:
I am making a sort of text based game (Just a hobby) I like to do that sort of thing. So, anyway, considering all I can really do is code HTML, and very, very light javascript, I kinda need some help.
I basicly know how to do everything except affect & Use the cookies. So what I need to do with them is to
#1.) Have a code to change the cookie number, say... on the click of a button.
#2.) Have a code where it only displays certain text if the cookie is a certain number.
I cant code JS and have no idea how hard/easy this is.
If it is insanely hard & needs a master coder, just tell me and ill take it off. I dont want to be wasting anyones time.
