how i would poppulate a select box with an ajax call.
Would anyone have a super simple function or script that will populate a select box without using a framework of any sort ?
All i need is for it to extract pull a list from my server
I'm having problems with a Javascript 'Lookup' function.
Basically, I have a select menu 'Customer' which triggers a 3 JS functions, to populate 2 extra select menus.
Using IE Developer Tools, during debugging, I get this error: Expected ';' Error
This relates to either: eval(ajax_CustContact[index].response); OR eval(ajax_CostCentreContact[index].response); (it's a bit random, as sometimes it works, sometimes it doesn't)
I have tried changing the 'custid' to 'custname' to check whether it was an integer causing the problem, but had the same problem.
I'm trying to get a select box to automaticly populate the year ranging from 2008 to the current year + two years.Below I've put the code I've got so far which populates it with the current year plus two years so for example at the moment it shows 2009, 2010 & 2011. Next year it would show 2010, 2011, 2012 but I need it to start at 2008 so this year it would show 2008, 2009, 2011 & 2012 and next year 2008, 2009, 2011 & 2012.
Code:
<script type="text/javascript">
var year = new Date();
var nextYear = year.getFullYear()+1;
var nextYear2 = year.getFullYear()+2;

I am using Javascript & PHP to populate a select list. The Ajax is working perfectly as I have tested it. However, as you can see from the below code, I have a button which adds more rows (which includes 2 select lists and file input) to a table.
When I click Add Row, the row is added perfectly and both select boxes along with the file field are shown as expected. The problem occurs when I select a value from the "room_name[]" box - there are no values returned inside the "album_title[]" select box. It doesn't seem to be triggering the onChange event.
code JavaScript:
function addRow(tableID) {
var table = document.getElementById(tableID);

I have a product select page that is really slow to use because 6 dropdowns must be populated and the page reloads after selecting each box, to get the options for the next box.I want to speed it up as follows:
1) User selects one of 50 products from a dropdown list.
2) Page reloads, and all the possible options for the remaining 5 dropdown boxes are now populated (ie. list options all stored client side)
3) User can freely input the remaining 5 dropdowns without the page reloading.
I have a form where a user may select a box from above which will query the database and autofill in the fields. This works properly for all of my input text fields but I have a select box where a user selects their state that I am unable to get to properly populate.
The select box is populated on page load in the following format....
<select id="state" name="state">
<option value="1">ALABAMA</option>
<option value="2">ALASKA</option>
</select>
[Code]....
Everything populates correctly except where I try to set the val on the state select field. It does not change at all. I need it to display the statename with the value of the state (number).
I would like to have a jsp page with a form consisting of several inputs and selects. When page loads for the first time, there is only one select (with values taken from database), but after clicking on link "add", the subsequent selects are added (using JavaScript and DOM). It seems to be pretty easy task, but I'm not sure how to populate the newly created select with data.
View 2 Replies View RelatedI have two select lists, the first one has three options in it, What I need to have happen is once a option is selected in the first drop down, the second drop down will be populated with the remaining two options.
View 2 Replies View RelatedI am populating a number of Select boxes on the server-side with a large number of options. I'd like to get the response size down without taxing the client browser too much. What do you think is the most efficient way to approach this problem?
Here are some considerations: The option text/values do not change very often, but could potentially change in the future. The page that holds the select boxes should never be cached, there are other aspects of the page that need to remain fresh. Firebug with YSlow is saying that the primed cache size of the page is 300Kb with all the select dropdowns and options, if I remove the options, the primed cache size of the page is 80Kb. I am considering breaking out the text/value pairs for the select boxes into a separate file that is cache-able calling it "valueTextPairs.js" and referencing it with a query string and some sort of server-generated MD5 hash of the data, so that if any of the values change, the client's cached version will be replaced by the latest version. Like so:[URL]...
Provided I do this, I anticipate that the primed cache size of the page will be reduced down to 80Kb (which I like) -- however, before I take the plunge, I am curious what you all think the performance effect will be?
I know the number of bytes on the wire will be reduced, but will this put a lot of additional pressure on the client's browser because I'd need to traverse the name/value pairs and add the options to the select boxes dynamically on the client end? If it seems reasonable to do this, what jQuery approach would be the most efficient? $('#selectId').html(options) with options = one big string? Adding each child option to the select in a loop? Something else?
Some client end folks are using IE6 so I am trying to tax the browser as little as possible, while also reducing the size of each request, trying to find a happy medium..
Is there some example js that shows how to populate a text field on a form, based upon what option is chosen in a select form field? The options can be hardcoded and it would be great to also have a default if js is off on the client side.code...
View 4 Replies View RelatedI have a page that runs a lot of calculations.The math is computed on the fly using java scriptwhen all the calcs are in, prior to form submission the user needs to evaluate which numbers they prefer, and from there, once they select them, the form, based on those choices, will perform one last calclets say we have 3 result fields
r1 = 2000
r2 = 3000
r3 = 4000
what i want to do is have a select field be able to display those values at the bottom of the page;for example
<select name="s1">
<option value=[field contents of r1 above]>[field contents of r1 above]</option>
<option value=[field contents of r2 above]>[field contents of r2 above]</option>
[code]....
I have a select field. I must fill with options taken from a mysql table.Here is some little php code I have done using codeigniter framework
$idcateg = trim($this->input->post('idcategory'));
$array1 = array(
'result' => $idcateg
);
echo json_encode($array1);
Now, the jQuery call...
$.post("<?=base_url()?>index.php/rubro/list_ajax/", {
'idcategory' : idc },
function(data){
[code]....
The code works fine. When I call the post, I get the categoryid as a result.Now, I should modify the code above, so I can do:post the ajax call sending the category id. this is done get subcategories for this category, and build the array * json_encode the array and echo * get results back in jQuery ajax call, decode and build the < select > field *The array should be built with each element having a sub-array with id and name, right?
I want to make a popup helps the user select a value for an input field in a html form.
For example, if the field is for a customer code - the user can either type in the customer code directly, or use the popup to search on available customer codes using various criteria and finally select the customer code he or she wants to use, and have that customer code populate back into the original input field.
I have been looking around the various components in jquery but can't quite see how to do this.
I'd like some direction on creating a small piece of Javascript that will populate my <select> boxes. Basically, I have a form for users to create events, with a start time and an end time. (These are the two select boxes). For example:
Code:
<select id="startTime">
<option value="12:00AM">12:00AM</option>
<option value="12:15AM">12:15AM</option>
etc.....
</select>
What I am trying to do is:
1) Have times populated in 15 minute incrementals from 12:00AM to 11:45PM
2) Have some type of "error checking" available to where the End Time must be after the start time. It would be nice for the script to automatically change the end time field to a time that is after the start time.
OK so Ive been using jquery for a little bit now and love it. I am a ColdFusion developer. I have a need where I would like to present the user with a list of categories and the user can drag and drop to sort, but then I need to post this new sort order to the database. So I see there are a ton of cool drag & drop plugins for jquery. I understand how they work and I can get it to work as far as spitting out DIVS or spitting out ULs that can be sorted, but then what? So now they are sorted on my screen and not really part of the form. How do I translate that into something I can do a post to the database with? Do I do an AJAX call every time they drop an item and try to extrapolate the sort order on that item after they drop it? Do I populate a hidden form field with the constantly updating sort order list? MAybe a list of ID's? How does everyone else go about this this task? I'm sure there is more than one way and I'm sure this is a common task.

I have the following object hierarchy Field --> Category --> Expertise which are displayed within a form as select elements, e.g., when 'Field' is changed then the 'Category' is repopulated based on the root index value of 'Field' and then 'Expertise' is repopulated based on the root index value of 'Category'.

what is the best js framework for ajax ? first iam a beginner in ajax and js,
i found a lot of frameworks but i didn't know which is the best.
And i heared that some of thease frameworks are not updated any more. I read a book called professional ajax with php and the book author was using a class library called zXml you can find it here but i found that the XMLDOM does not support opera browser it supports only IE and FireFox .
And I heared a lot about prototype class library but i didn't found tutorials using it you can found it here so iam unable to deciding which is the best updated cross browsers js framework for ajax.
Iam planning to build a good 2.0 web application with minimal modules but each module should be feature rich.
so i would like to use AJAX to spice up my site.
(i will be using php and mysql for it)
so please suggest me, should i hand code everything or should i use an AJAX framework?
if so which is good ajax framework and why?
I get that this question is going to be one of those questions where everybody defends the app they like the most, but I am asking for the reasons why rather than just a one product name answer, so here goes with the question:
What is the best Javascript Framework to use for Javascript RIA development and why?
i.e. Qooxdoo, ExtJS, Echo3, etc?
Now I know everyone is probably going to jump in and say Jquery, but personally I see Jquery and the likes as more of a "make plain website nice by adding animations etc" rather than for web applications development.
One of the great annoyances I have with JavaScript is the lack of a good
consistent code library. Oh, there are a few code libraries scattered
around for doing various things. The problem is that each of them have
their own way of doing things. If we want to use more than one library
at a time, we often end up duplicating code and working with different
interfaces and practices that aren't necessarily compatible with each
other...
So... isn't it about time that we have a Common JavaScript Framework?
I'm thinking of a standardised code library, mostly (but not entirely)
built from the free code that is already out there. (I'm thinking of a
LGPL core with independantly licensed extensions.)
I know of a few very cool projects that aim to make JavaScript
development easier, more professional and to bridge the gap between
browsers and environments. (To name a few: DynAPI, DOMAPI, Sarissa,
13th parallels' library, netWindows, bindows, ActiveUI, f(m).) But I
don't know of any effort to bring all of these features into one common
framework. Can we do anything about this?
I'm not exactly proposing that we form a group to design and implement a
complete framework. I just think that, us, JavaScript developers should
talk to each other more and agree on a few things. Then, I imagine
being able to access this centralized, well designed library that is
ready for serious (and less serious) development and the dream goes on...
I have been working with JS (client and server) for some years now and
I'd like to bring more consistency to my code and spend less time
writing lower level code. So I may be writing this email more out of
wishful thinking than determined action. In any ways, I remain
interested to support any effort that would lead me to better, well
designed, programming.
I'm experienced with PHP and I'm familiar with JS syntax but still a beginner.
Now I want to learn AJAX And JS and I've looked at jQuery but it doesn't look like JS to me, I mean I'm sure it is but it looks to me like jQuery has a syntax of it's own and I want to learn not just a framework but also the underlying language.
So now my question is; what framework will be the best choice when that is my goal?
AjaxI need to know which is the most used framework and why.
I know that there are many websites on the web about it, but I can't use them only.
I never use jQuery, but i saw jQuery in zul pages from ZK framework. i'm ZK developer here.
So my question is just same with my subject,is that possible use jQuery in composer.java?
Where can i find the procedure for build my own website. It would be a great help if anyone give the information.

BUT, without needing a framework (jquery,mootools,scriptalicious,protoype,dojo,etc). I don't need all the extras that come with the framework and want to keep loading time down to a minimum.
Everywhere online seems to need a framework.
