There can be any number of 'groups' but I would want to apply some validation for each item in a group. I can only see that the validation is done by specifying a id? however as the id's are going to be dynamically created how can I do this? can you validate for a css class?
So, I have a form that, when the user clicks on a link, uses J/S to generate extra form fields for extra information. I can retrieve the value of the dynamically generated fields using $_POST in I.E., but it doesn't work in Firefox (no value is returned). Retrieving values for the static fields is fine in both I.E. and Firefox.
Here's the code - is there a function I'm using that could be replaced with something more friendly to Firefox?:
<script type='text/javascript'>
var i = 1;
function addArea() {
var newArea = addElement();

I am working on an MLA citation PHP script for books, and I already finished that part. I have the page set up so that the user may add as many authors as needed. However, when I use the back button, I notice that if I have more than one author, the dynamic text fields are gone and all data after the dynamic text fields are not loaded back into the proper fields.I've spent the entire day searching for solutions, and I tried saving the code to a textarea, then using that code to insert it back into the page on loading. However, I couldn't get it to work.[code]

As you can see I'm generating new form fields, but the problem lies within the grade field. I have it set up now so that when you change the grade the color of the <select> box changes relative to the grade. A-D are green, F is black with white text, Not Taken is just regular white with black text and In Progress is lightly shaded grey.
I want it so that each one can be changed individually, but I can't seem to be able to figure out how to do that. Heck if you change the first one's grade field, that colour follows the rest of the clones.
This is the jQuery I'm using to change the color of the thing.
$("select").change(function()
{
$(this).each(function () {

When the user enter a value into the quantity input field it calculates the first amount another entry to the same field would calculate the second amount instead of the second input fields entry. The other input fields behave the same as the first one. How do I match the input fields to quantity? Here is the code.
<code>
<?php
include_once ("db.php");
//include_once("common.php");
?>

I've got a form that dynamically generates sets of input elements. First there is a set of up to 99 parent elements, and then the parents can have up to 99 child elements each. My question is not about the generation, but about capturing the data once the form has been filled out.
I made a script that handles getting the values and putting the values, along with their input id in an object that is used later. I don't want to have to use css classes or other attributes to identify the input elements, and wondering if that being the case, if I could get a critique of my script:
Edit this Fiddle - jsFiddle - Online Editor for the Web (JavaScript, MooTools, jQuery, Prototype, YUI, Glow and Dojo, HTML, CSS)
The output (the object) logs to your console when you click anywhere in the Result area.
I'm trying to add dynamically generated HTML after the page has loaded. I've tried two versions.The latest versions is this, using insertBefore (as appendChild is buggy in a few browsers according to the SitePoint reference) ...
Code:
addImageField: function(x) {
var newNode = createImageField(x);
var src = document.getElementById("imageUploads");
[code]...
The first alert returns: object HTMLFieldsetElement .The second alert returns: object HTMLDivElement....and the third alert fails to fire, indicating a problem with the code above.Note that if I change the problem line to remove the null reference it still doesn't work (again the third alert won't fire):
Code:
scr.parentNode.insertBefore(newNode,src);
I am not new to jQuery but I just want to ask the best way to approach this. Basically I have a textfield in which the user is going to type in a number (for example 20) and after this textfield lose focus jQuery will be triggered to create whatever number of textfields the user put before (in this case 20).
So, to illustrate: How many users do you have: [ 2 ](and after the field above lose focus, the below will be generated)
Fullname: [ ]
Fullname: [ ]
At this point I have been able to add the row. But what I want to do and am having trouble with is alternating the row colour to the dynamically added row element.
Sample of code I am using:
Code:
var tbody = document.getElementById('tableItems');
var row = document.createElement("tr");
var remainder = tbody.rows.length % 2;
if(remainder) {
row.setAttribute("class", "rowLightGreen");
}
var td1 = document.createElement("td");
td1.appendChild(document.createTextNode(qty));
td1.setAttribute("class","qty");
row.appendChild(td1);
tbody.appendChild(row);
One thing that puzzles me, is that even after adding a row the table my table.rows.length still = 0.
Does anyone know how I can determine the appropriate amount of rows so that I can apply the appropriate class?
Or is there just something blatantly wrong in my approach?
I want to dynamically generate list box options using the content of an sql database in real time. More specifically, i have a page with a couple of listboxes, when i click on an option in the first list box, i want the second list box to update with options that reflect the first one, in real time generated by the sql database.now i was wondering if it might be possible for javascript to send some thing to php which php could decode and search the database and return the results of that search. here is how i imagine the process to look in psudeo code:- user clicks on an option (say the 3rd option) in the 1st listbox- javascript catches the event, and sends some data to php indicating the 3rd option from the 1st listbox has been clicked- php tells sql to search for records that correlate with the 3rd option from listbox 1- php sends search result back to javascript- javascript populates the 2nd listbox with search resultsi want to do this with out having to refresh the webpage, security issues aint high, cause this project probably aint gonna go on the web. I got the idea from the dynamic searching on google, so i guess such technology is possible some how.

I'm stumped on a jQuery related development task. I'm using jQuery in a SharePoint Web Part...The web part pulls data from a list and displays each item as a link button. When the link button is clicked it uses the jQuery-UI to display the body of the list item in a dialog box. I have this working perfectly when all of the class names are hardcoded. So in this code dialog0 is the class name for the body of the first article. newTitle0 is the linkbutton so they correspond 1:1 (and so on Dialog1, newsTitle1 etc..)
$('.dialog0').dialog({
height: 500,
width: 990,
autoOpen: false,
[Code].....
Problem is, when I have more than 1 instance of the web part on a page, because they use the same class names (2nd web part would also use Dialog0, newTitle0), if I click on an item in one web part, the item with the same class name opens in the other web part as well.
I've implemented it so each item now has a unique ID but I don't know where to go from here, so multiple instances of the web part can be on the page, and have the jQuery know which body to display when a link is clicked.
I'm having a problem with the page at http://www.bathfringe.co.uk/contributors2011_2.php
The user is able to add new performances to the form. This functionality is provided by cloning elementsPart of the code should add a 'counter' array key to the names of the cloned form inputs (full code obviously available at the page linked above):

I am dynamically generating javascript arrays in my custom tag
This is the java code
autoCompleteResult += "<script> var valuesInListOf" + displayProperty + " = new Array();";
I can see this variable in debug on client side in javascript, just not sure how to access it.
in javascript
var values = "valuesInListOf" + displayProperty;
this gives String variable whereas I want to access JavaScript Array that I created in my tag.
Here is the code:
function selectDefaults(buttonGroup){
for (i=0; i < buttonGroup.length; i++) {
if (buttonGroup[i].checked == true) {
for (count=1;count < document.addForm.recordCount.value; count++) {
var doc = document.addForm.feature1[i]
var featureVal = doc.value;
featureVal = featureVal.substring(0,2);
if ( featureVal == "SF"){
doc.checked = true}
} }}}
I need help in the second 'for' loop. Currently it is hard coded to replace the value of document.addForm.feature1 - but this field name is dynamically generated via the page it resides within. That being said, its name/id will increment depending on how large the recordset is. i.e. feature2, feature3, feature4 etc....
How do I get this to work in the javascript? I need to use this script to search all the 'feature#' fields in the form when the script is triggered. All I could think of was this: var doc = document.addForm.feature+count+[i]
which gives me a syntax error.
The purpose of this script, for those who will wish to know, is to automatically select all the features of the product that have the text "SF" (standard feature) in their value.
I cant seem to get the reference to the 'header' IFrame that is dynamically created. I can reference one called 'footer' that is created in the same line of code as the other IFrames however (oddly enough). I've tried numerous ways with no luck. Since this is inherited code and designed years ago to run on IE only it's a mess. You'll see I've tried alerting out various different ways and simply left it in to show my feabile attempts.
Code:
function mit(e) {
var iframeElement = document.getElementById('header');

I'm writing a page where I'd like to generate a bunch of fields using javascript and then make them usable by datepicker. The problem I'm running into is that when I first click on one of the javascript generated fields, datepicker doesn't load. However, if I click on a second instance of that same field name, then datepicker will load properly. My guess is that I'm just defining the function incorrectly for these events.
View 1 Replies View RelatedI have form elements which dynamically generated like this...

I have a jsp file that is used to display data from Java objects running on my server. I'm using JQuery for tabs and to handle the ajax calls to a servlet that affects the Java server I have running.Each tab represents a service, and has a corresponding java object on the server side. These are generated from the spring configuration, and is working fine. The page is used to control some aspects of the service, and I have a few buttons that can be clicked. I'm trying to get it so that when a button is pressed, the appropriate Java function is called on the service's object (this happens using ajax) and then refresh the current tab.
My js code is like this:
function doPause(params) {
//some additional params set
doAjax(params);
[code]....
Right now, I'm using the window.location.reload(true) to refresh the whole page but I'd like to just redo the div for the tab that contains the button that has been clicked.I have tried:
$("#"+params.client).load("monitor.jsp#"+params.client);
instead of the window.location calls above, but that puts the whole page into the tab.
I have script that is dynamically generating updates on my page. The code is this:
Code:
<a id="cc_stream_info_song" target="new">Loading...</a>
The id tag links to a js script on a remote server and replaces the "loading" text with the song title of the currently playing song on my shoutcast server, and refreshes this every 60 seconds. I want to be able to grab this song title and put it in a php variable. I don't have access to the remote server, so I don't have any other way of getting the updated song title outside of this little snippet. I tried using php output buffering but all that does is grab the html I posted above, and not the javascript-generated song title.
I want to add an event to a generated SELECT field. It's an onChange call to a function named calculateSubtotal(). The result I want would look like <select name="..." id="..." onChange="calculateSubtotal()">.
This is what I've got so far. The drop menu is created with no error, but no onChange either. Code:
var newTour = document.createElement('SELECT');
newTour.name = 'registour' + rowCount;
newTour.id = 'registour' + rowCount;
var newAttrib = document.createTextNode('onChange="calculateSubtotal()"');
addOption(newTour, '');
addOption(newTour, 'Tour 1');
addOption(newTour, 'Tour 2');
addOption(newTour, 'Tour 3');
document.getElementById('groupreg').appendChild(newTour);
document.getElementById(newTour.id).appendChild(newAttrib);
I also tried this, it doesn't work either:
newTour.onchange = 'calculateSubtotal()'
I'm using a javascript to alternate table rows and it works fine by table id, and on the first loop. This is all inside a conditional, in which the table tag is repeated.
On the second and subsequent loops, the alternating row color fails because there can only be one unique id call to a page. Right?
What's the script that will allow unlimited reiterations of tables with alternating row colors, using class?
Is there a way to access a form element that was created using AJAX?I've had no luck when using 'document.getElementById( elementID )' as the element doesn't appear to be recognised.
