I have a form with a textarea that can hold a lot of values. When submitted, a php-script takes over and processes the textarea line by line. When a lot of values is submitted, it can be time-consuming for the php-script, causing the webserver to timeout.
I would like jquery/ajax to send one or a few lines of the textarea to the php-script at a time, hence feeding the php-script with a lot of smaller requests instead of one massive one. Kind of like an upload form with a progress bar, but for textarea values instead of file submition.
I have looked around and failed to find any examples or tutorials on this, and since I'm not very experienced in javascript I would really need it.
So again, the javascript would check the textarea-field when user submits the form, and send one or five values from the field at a time to a remote php-script. In the meantime the user can be presented with a "loading..."-image or a progress bar.
Based on a simple AJAX way, I can run a php process and return the result by this line Code: xmlhttp.open("GET","getuser.php?q="+str,true); There is another method using jQuery (e.g. in [URL]). But here, it shows a predefined message in these lines
Code: //hide the form $('.form').fadeOut('slow'); //show the success message $('.done').fadeIn('slow'
How I can return the output of the php script within AJAX instead of this message?
My login to the site is being processed using ajax, which does a redirect to the members page upon succesfull loggin in.The login feature however can in fact take a while because we need to initialise quite some data when a user logs in (his details, but also his privileges are loaded, his personal menu based on these privileges are being loaded, we are loading shopping cart info, we are initialising personalisation settings, and a whole lot more.It sounds like a big thing, but it isn't, and once logged in, the application is going great. the only thing is that the login proceure can take 3 - 4 seconds, and I would like to be able to show the client the progress of the serverside script:
"Searching your account..." "Validating your privileges" "Initialising your personal menu" blablabla...
To do this, I might just call an ajax call that starts the login procedure, and then issue another ajax call every 1 second or so to update the status based on some session variables I set in the login procedure and that I can serve to the client when th next ajax calls come in, but I would love for this to work a little nicer as in just needing to initialise ONE ajax call which can send back statusupdates from the server...
I have a form, and that has many fields, upon submit, it utilizes AJAX (PHP script) to store the data in the database and if the readyState is 4, (as a result of the PHP process) it shows the results on the same screen.
Now, I want to put a CONFIRMATION box, in the process, like I want the script to take input, and once the user hit submit, the php process begins, and if there is a duplicate entry it will show the message to the user like:
"Record exist" [Overwrite] [Make New] [Cancel]
the next, AJAX will continue based on the user input.
how to do this ? Should I have to make 2 Ajax Calls ? one to check for Duplicate and then one to get the input and process further ?
I guess the title says it all. I've generated two checkboxes and two textareas via an ajax requst. When I later on call anoter function I want to get the valus from the textareas and to know if weather the checkboxes are checked or not. But that seem impossible to be as you seem not to be able to select an element generated after the page load, or am I wrong ?
I'm using ajax to process a form. But my form has textareas in them. Its not passing the textarea values. Here is my javascript code: $.get( "process_order.php", $("#order").serialize(), function(data){ $('#loader').hide(); if(data) { pTag = "<img src='[URL]' width='200px'><br />Order Saved"; $('#popup').empty(); jQuery("#popup").append(pTag); jQuery("#popup").dialog('open'); } else { pTag = "<img src='[URL]' width='200px'><br />There was an error!<br /><font size='1px'>" + data + "</font>"; $('#popup').empty(); jQuery("#popup").append(pTag); jQuery("#popup").dialog('open'); }}, "html" ); I just have a simple textarea section and I NEED to allow HTML code in that text area.
I'm having some issues with getting the value of a textarea which I fetch with jquery's ajax function.I'm displaying some comments in my ajaxcontent. All the comments have a onClick quoting link which is supposed to send the id of the textarea which is to be quoted.
I'm trying to achieve something that I originally thought would be very simple, but I can't get it working....and even googling hasn't helped this time! All I want to do is update the innerHTML of a div with the content of a textarea object when a button is clicked. I'm trying to avoid having to post the form using AJAX because the button also replaces the innerHTML of a different div with the value of a text input box. Here is the code I've tried, but it doesn't work:
Code:
function previewContent(intContentId) { var titleText = document.getElementById('edit_title_' + intContentId); var titleDiv = document.getElementById('content_title_' + intContentId);
[Code]....
In this example, the titleText var represents the text input box, and the contentText var is the textarea. The titleDiv gets correctly updated with the current value of the input box, but the contentDiv doesn't seem to consider any changes I make within the textarea - it just loads the original content. This seems very strange to me. Is there an easy way to retrieve the value of the textarea?
I have created a simple AJAX chat that polls the server every 2 seconds for new messages. The messages are displayed in a div layer, and the user types new messages in a textarea, the only problem is that when a new message appears it takes the focus from the textarea so you have to keep clicking back in the textarea to keep typing. Does anyone know how I can solve this?
You have to go open the navigation box on the top left (sorry I have to simplify this in the future!) and then click the third link Compare Two Bible Texts. Once you enter a word in the first textarea and select the book, chapter, and verse it doesn't record it in the textbox underneath the verse dropdown select.
How would i change back to the default length of textarea?
I have this comment area that after clicking submit i will append the new comment in the list of comments through ajax... i got one problem though, everything is working perfectly well except for the textarea that won't change back to it's default size...
EXAMPLE:
The problem is that the textareawon't change back to it's default size // let's say that the default size is rows=3
I am currently using change and keyup to trigger a div loading process according to the select box. This works fine, when only mouse is used on the box. However, when the selection is made using arrow keys, this is what happens: Target div gets loaded fine, but when I click anywhere on the freshly loaded div content, it blinks. My guess is that change event is triggered after keyup, when it is not needed anymore. Is there an event or combination of events that detect selection change with both keys and mouse? Here's my simplified code:
Can I do the following without my program crashing? [code]...
I have created an application that does something similar to the code I just posted. However, my program crashes intermittently. Sometimes it will crash after calling jQuery.get() a few times (with several http requests still pending). Other times it will get through all of them just fine.
I want to know if Ajax can handle that many asynchronous requests without crashing? Can someone look at this to see if there is something I am missing?
I'm struggling to find out the correct bit of jQuery to use, so that I can repeat a process 4 times. I am trying to achieve the following: When 1 <a> is clicked, I want jQuery to add the class current to that <a> and the next 4 <a>. All I need to know is the correct selector or filter to use in order to achieve this?
I want to show a process dialogue to the client till my process completes on the server. As long as my process dialogue appears, client should not be able to edit the page (or page become inactive); How to do this?
FYI, I am using jQuery 1.2.3, and the latest version of the jQuery Form plugin from URL...I am able to run the ColdFusion page on the server side to get the data, and Firebug is showing that I'm getting a response...but I'm unable to populate the JSON data into selected form fields on the page.I have two HTML forms; one for the user to input his/her ID number if available, and a longer form to collect more demographic info.Why is it not working? My forehead is getting bloody from banging it against this wall.
I have a four part process to add something to my website. I'd like to have a bar at the top of my page (if you need an example, something simliar to FedEx to show where you package is along the way) that will get updated upon each page move so the user knows how far along they are in the process and how much farther they have to go?
