I work primarily with php, and haven't had much experience with JavaScript. I was wondering if JavaScript is suitable for automatically updating a database with the contents of a text area, at intervals of 3 minutes... without refreshing the page? It doesn't have to change the content of the text area, just take a snapshot of it. I am trying to develop an 'autosave' feature.
View 3 RepliesIf I have a jquery var, such as:
var foo = $(this).fieldValue();
And within the </script> block I have a bit of PHP code that generates json, I want to pass the var to the php/mysql code such as:
Code:
$sql="Select from table where qid='foo'
In other words, how does a php/mysql query, in php code, grab the value of a previously declared Jquery var?
Does anyone know how to set a javascript variable as a query result from a MySQL database.
As an example, like this:
Set this query:

Firstly this isnt a double post, I stupidly posted in the Java forum not the java script forum. Im trying to create a dynamic table based on the selections of multiple lists as per here Screen Shot
A user would select thier choices from the various lists and then add them to a table - this is where my question comes in. How do I achieve creating a table which will grow depending on how many additions a user adds?
Hope I make sense, Im trying to get my head around this.
I want to add a comment system after my article, <form id="postform" class="postform"> is written into a MYSQL_QUERY result circle. but after post a comment, the current posted comment will be showed in all the <div class="post_comment"></div>, how to modify jquery ajax part so that the current posted comment only be showed in its own <div class="post_comment"></div>?

View 9 Replies View RelatedI have a page of rows of dynamic data... the user can click on a link for each entry... that allows them to open a popup window... add / edit or delete some sub-entries for each entry.
When they close the popup window, how can I get the background page to refresh and show the updated data... without pressing the refresh button...
a) could I get the page to refresh automatically every 30 seconds ?
b) could I get the popup to switch focus to the window that opened the popup and then refresh that page?
I'm currently trying to refresh a DIV on my page that is linked to MYSQL (changes if database has 1 or more rows) without refreshing the entire page, I've tried using javascript although it didn't seem to work and so Im back to the drawing board, Im not very experienced with Jquery or Javascript to do it on my own, I only know PHP, CSS, HTML the easier ones
how I could possibly go about this... - I don't want to use Iframes either as the the div is a button which opens a hidden div on the page (parent page) so I don't think iframes would be best either
I am attempting to create a profile page with PHP utilizing AJAX technologies as well. I need profile data to auto-refresh on the page when a change is made in the database but every 15-30 seconds intervals are fine too. I would really like to use AJAX/PHP for this because I think it will be good for me to know and learn.
I have checked the internet for this and all of the examples show a form select/combobox where you select a "User" and then it populates the information automatically in a div below.
But... I need AJAX or PHP to READ THE VARIABLE FROM THE URL instead of a form(Combobox) and ultimately refresh the data on the page with the results from the DB query in the php file.
I'm wondering how to add predefined text to many input fields on click of an image. so I have 4 images and I click one and 4 fields are filled with predefined text. If I click another the text is changed with some other predefined text.

View 3 Replies View RelatedHere is what I have at [URL]...Basically I setup a function for message selection that will call an AJAX request. Once content is loaded via .html() in my #messages div, I could not click links from within and have to use .delegate().
The code works fine when I copy and paste code from my message_click function, but if I access the function from within .delegate(), it does not work. Is it possible to use a predefined function with .delegate() or will I have to continue to reuse code?
I'm an experienced programmer (c, perl , python, bash) but absolutely newcomer with Javascript. The code I'm experimenting with is shown below. What I'm trying to do at this point is define a function in a script section in the head of my html page, then call that function in the onclick action of a form button. Sounds trivially simple, but for some reason it isn't doing what I expect. The eventual result will be that the Javascript will launch a Silverlight video player using the values supplied by the end user, but for now I just want to get the basic buttons to work.
<code>
<html>
<head>
<title>Silverlight player</title>
<script type="text/javascript">
var vProto;
var vServer;
var vStream;
function showMe() {
alert("In the function");
vProto = document.getElementById('proto').value;
vServer = document.getElementById('server').value;
vStream = document.getElementById('stream').value;
return false;
}
function alertMe() {
alert(document.getElementById('server').value);
return false;
} .....
I have been reading and practicing Javascript for the last month and so far I'm happy with it. I noticed that you can add Event Listeners and trigger a function based on that event but I also noticed that you could add an event directly to any element as an attribute, something like:
Code:
<p onclick="doSomething()">Click Me</p>
function doSomething(){
//do something
}
So my question is why would someone add and event listener instead of adding that event directly in the element (as the sample above)? The reason I'm asking is because adding event listeners involves more code:
Code:
var elementName= document.getElementById('elemenstsID');
elementName.addEventListener("click", doSomething, false);
I guess what I don't know understand is why would someone choose to add an event listener instead, I know it is more OOP but doesn't the "onclick","onload" etc., do the same thing?
I want to open a new browser-window with javascript and fill some
input-fields in this window with predefined values. So the User does
not have to edit the input-fields manually but only has to submit the
form.
....
var childWindow = window.open("http://anyForm.html");
childWindow.document.getElementsByName('anyinputfi eld')[0].value='hello'
....
Unfortunately this does not work... Mozilla throws an error:
"Error: uncaught exception: Permission denied to get property
Window.PropertyIterator"
Is there any workaround?
Is there a way to find if any intervals (set by window.setInterval) are still open? I just want to have a way to double check my code ( in debugging) and be sure I'm not leaving any unclosed.

I want to make an animated gif that runs through one loop
and then stops. But I want to invoke it at random time
intervals...so, for instance, a tight head shot
of a person's face winks at the viewer once or twice per minute,
at unpredictable intervals.
I think I could figure out how to use rand() and setTimeout(...)
to create the random time intervals, but I'm not sure about
how to start the one-loop animated gif. Would I have to reload
the whole page? Or is there someway to restart the gif animation
*without* reloading the whole page?....probably not, the more I
think about it.
I'm trying to build a tee-time reservation page, and want to display
all the available tee times on one page for a particular date. I
simply want to list the times out in 10-minute intervals, like:

8:50am

have entries in my SQL database, but for now I'll settle for just
getting the times listed.

View 1 Replies View RelatedIs it possible to extract information which is located in a predefined area on the screen from a java platform?
For example, there is java based platform which I can see on my screen.
This platform contains numbers/letters.
The location of these numbers/letters does not change, i.e. the script would not need to be adjusted if the field, which contains the info, would move.
Lets assume the screen would look like that:
The info between the fields would be clearly separated.
Now I would like to extract the infos from all the fields and paste the info for example in EXCEL so that I can see "Valerie12345" in .xls field A1 / 12.20 in A2 / Love in B1 etc...if that is possible to extract?

I've found many examples of creating slideshows using javascript all over the internet and these forums. However, I haven't found any that show how to create a slideshow and give each slide a different time interval between switching to the next one.
I'm changing my website over from a Flash based one to something that can be read on all devices. In doing so I've looked for ways to add a little motion to the site. I'm working with a friend who has been doing most of the site but here and there I like to get my hands dirty and try some things on my own. Unfortunately he doesn't know Javascript.
I wanted to have an animation window in the bottom corner of the page. Look at [url] to see what I came up with. I took a slider plugin for Wordpress and basically created a bunch of slides and entered them in to switch every .5s so that I could change how quickly they changed images by making some of them repeat the same slide 4 times for 2s, 2 times for 1s, etc. Though it's not pretty, it works. On Firefox everything looks great although it'd be nice to have fade in and out on each slide. On an iPad or IE it actually shows the flash between slides even when they're the same image. Quite frankly, it's ugly. Does anybody have any ideas?

$("#getrecords").load("x.cfm?u=1");
