When I Submit The Page No Data Is Received At The Backend?
Apr 5, 2009
I have hidden form field in a page. I populate it through JS and submit it.The problem is the data is text and it is really huge. The text is around 50000 chars.So when I submit the page no data is received at the backend. I do get the data if it is less i.e if I have few chars, I do get the data in the backend.I have the following Qs:
- - Is there a limitation in the number of characters JS can handle? If yes, What is the limit?
- - Is this happening cause the hidden form field is unable to hold the data? (I dont think this is the case as the other elements like textare etc can hold the data)
On clicking a thumbnail I'm getting it's corresponding image through $.ajax method. So, the data I receive is in the form of html string i.e. <img src="image/1.jpg"/>. Now I wanted to append this data into a div which has an id "container". So I done this by: $('#container').hide().append(data).fadeIn('slow');
I have a function named "resize" which resizes the image according to the window size. Now when i tried this: // this code is in executed on success. $('#container').hide().append(data); resize( $('#container img') ); $('#container').fadeIn('slow');
I had to click a thumbnail twice to load the image into the container. I don't know why is it so. So, I tried a different route. I tried to apply resize function upon the <img> tag received as data and then append it to the container div.
Which I did like this: resize ($(data)) //alerting $(data).attr('src') shows the src of the image. $('#container').hide().append(data).fadeIn('slow'); The image loads but it is not re-sized. What should I do? The re-size function I'm talking about, u can see it here: [URL]. Right now, I'm calling the resize function in the callback of fadeIn method, the image fades in and then resizes, but that looks very ..... unprofessional and ugly.
on my page I have a link to a popup. when the user clicks on the popup how can I save the information that has already been changed on the parent page, because when the popup (child) closes it refreshes my page(parent)?
I want to be able to open a window with a variable. For example, I will use domain.com?reference=1234- This link will open a pop up window as follows:
<a href="javascript:popUp('http://www.domain.co.uk/staff/tpr/update_action_log.php?action_reference=<?php echo $row2['action_reference']; ?>')" title="Click Here edit this entry"><?php echo $row2['action_reference']; ?></a>
When I open this window, it is always showing data put in last, it isnt refreshed. I wanted to open this pop up window, enter data and then click submit and make the data enter the database and then refresh the parent window. Every time I have done this, either the parent or the pop (or both) is showing old data.
I have a credit card donation page and what I wanted to do is after they click the submit button and transaction is successfult I wanted to capture the donation amount they enter from the donation page and show it to the next page.
I'm developing a simple CMS and working on a backend now. I want each, lets say, article to have a slideshow editable through a backend site. I created a list of images loaded using PHP from a MySQL database - they are <img> objects in a single <div>. To each <img> belongs a small <div> containing 3 <a> objects formated as buttons: move up, move down, delete (the order of images does matter). This is how it looks like:
The following will submit the form data to popup by clicking the submit button. I want it will submit the form automatically to the popup, there is no submit button in this page. Basically this page should not show up.
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 implementing a drag and drop newsletter, where my users can drag content to different areas of a template. Depending on where they drop the content, I need to add different HTML attributes to some of the code (essentially need to make the images float:left if they're dropped into a certain box). I've achieved a basic version of this using this code:
$('.review_list').sortable({ receive: function(event, ui) { // somehow need to make this only apply to competition/ mainfeature
[Code].....
This adds align="left" vspace="4" hspace="4" onto any image dropped into an element with the 'review_list' class (I know I said it was float:left but this code will be emailed so I have to do it old school style...). Anyway: is there a way that I can get the element that has received the sortable item? It could be one of three in my case, and I only want this code to be added for two of them. I guess I could run a cleanup function when submitting that removed this addition for images in the other element, but this seems messier - I had assumed that the 'receive' event would return the receiving element.
I would like to request my SQL database only when i clic on the header of a mail, and avoid to preload all the mails. The other problem, much important in my case, is to mark the mail "read" or "unread". There is a column in the SQL database for this. So, the mail needs to change to "read" state when I click on his accordion's header. Before using accordion, I was using simple link which reloads all the page. I've no problem with PHP/SQL, but I'm not so good in javascript/jquery, or ajax...
So, is there any way to execute this code when I click on a header? After that, I'll asking you how to change header style to differentiate read/unread mail (in bold for example, or change background image/color).
I'm trying to parse a Json string received by $.getJSON(). I can receive the string but firebug gives me an "invalid label" error. I think it is because the string is an hash array with a number as first label, but I'm not sure. This is the string:
{"15":{"id":15,"x":0.4589937586135409,"y": 0.8324914620560137,"z":-0.9435707004102728,"rawData":"1256204002860 13 -442866538 18392602 647462767 314 1777206957 -1664784174 "}} and this is the non-working code:
I am trying to find a way to get more than one characters pasted on html text field (input type=text), using onkeydown or onkeypress, I am NOT interested in onkeyup(it works), so please do not suggest me this solution. Also I am not interested in Jquery, I do not like to use it. I need solution to work with all browsers.
I am able to do that if you type one character, by taking the character of the event, but till now I am unable to get group of characters come from the paste (ctrl+V) or by mouse.You can look at Facebook search menu that shows auto complete results, it works on events: onkeydown and onkeypress and you notice that you get the result before you release your finger, try to paste something (more than one character) and you get the result before releasing finger, how? Onkeypress and onkeydown do not show first thing you paste or type because they happen before the text being added to text field.
Code:
<input type="text" id="targetTextField" onkeydown="CapturePastedString(this.id)" /> <script> function CapturePastedString(id){ var targetTextField=document.getElementById(id); // below I need to capture the pasted string like: var pasted_string= function(){.....} targetTextField.value=pasted_string; } </script>
I need to parse an HTML string received from an AJAX request. I wrote a function that places the HTML string into an unappended (not added) <div> , which opens the string up to the DOM hierarchy. However, when I try to access the elements of this <div> , I get an error in the console that says root.getElementById is not a function. This tells me that I can't access any of the child nodes.
Here is what my script looks like:
function parseHTML(html) { var root = document.createElement("div"); root.innerHTML = html; // The error console stops at this line
I'm trying to write code where an ajax function, at a specified interval, calls php script to query a table and open a certian window according to the response(variable) received. After that, the ajax function will continue to call the same php script but will open another window only if the response or variable is different from the previous request(s). What kind of method should I use to achieve this?
In the BOTTOM Division i have a list box and Submit button in a form. User can select an item from the list box and click on the submit button. After user clicks the submit button i want to display some data/graph in the bottom division. However with my current code i see that on clicking the submit button , the data is displayed on a fresh page.
I am writing a small data entry screen that will post the form data to a page and return a message. But i cannot get the Success or Error functions working properly.
Here's the code where strData is the posted querystring of:
I'm not sure whether it should be in a form and using the onsubmit or click of a button.
Im working on a backend panel where i populate a simple table with a few text boxes in there so they can update some values. I also have at the end of every row in the table an Edit, Delete & Save button. When i hit the save button i would like to update that entry in the database.
My Problem is that i need a value from the table before hitting a submit button, and the element names are dynamically created meaning ill likely need a variable sent from php to javascript and once i have the value in javascript ill need to send it back over to the php to manipulate and send to the server.
From wat i can gather using 'document.form.element.value' is the best way to go, hence why i posted this in javascript when most of my code is php.
So when I submit with jquery, and try to get with php the data
It does not see such index.
But when I change button type to submit and remove javascript code for submitions, then it works. Have you idea, why it works differently when I submit with jquery and what to do?
I am reciving the (ajax) response res and diplaying in <div id=homepage> , i want to know is there any way to call a js function after i have recived/displayed the reponse inside <div id=homepage> .
I am working on an application and it needs to access a third party service through an iFrame. I basically need to know how I can have Javascript autofill the fields and then submit the form that is contained in an iframe. Is this possible?
I've built a form in a mobile app where the user chooses a photo from the camera roll, they hit an upload button and the image is submitted to my server. The file is renamed by the PHP script and moved to the correct folder. All this works great.
I need a way to send the new filename back to my app and I'm not sure how exactly to do that.
The reason I need the name back from the PHP script is because I will then ask my users of the app to fill in a title and description and then i just want to submit all of the data together.
