Here's my situation:
I want to loop through a set (10) of similar named form elements to check if they are blank:
for (i = 1; i <= 10; i++)
{
if (document.form1.firstname??.value=="")
{
alert("A FIRST NAME is required to proceed");
document.form1.firstname??.focus();return false
}
}
My question is how do I refer to the loop variable "i" in location "??"
I'm working on a script that will produce multiple dynamic forms based on the results of an ajax request. The ajax request does a db query that will return 0 to x number of rows. For each row, a new serialized form is created. Since the forms do not exist at page load, I'm having problems getting the value of the form elements so that I can run other functions on them (update inputs and selects). I've stripped down everything so that I can show a basic example. In the example, how would I get the value of "#orderID"? The body contains a div (previousList) that has a list of items that when clicked will trigger the ajax query. It also has a div (line details) that will hold all of the forms that are generated.
<div id="lineDetails">
check it out </div>
<div id="previousFrm" class="ui-widget-header ui-state-highlight ui-corner-all">
<h3>Previous Returns/Cancels</h3>
<div id="previousList">
<ul class="previous" id="returnList">
<li id="1000997" class="names">1000997: 101853</li>
<li id="1000995" class="names">1000995: 101853</li> .....
But callingconsole.log("order line value is " + $("#orderID").val());
results in 'undefined'.
I try to make a dynamic form with inputs depended on selects fields. My method works in static form but I don't know how to use it in dynamic one.
JSON function ( to control correct input with select)
$(document).ready(function() {
$('select.sf').change(function() {
[code]....
Im trying to make the VALUE element within a form dynamic using JQuery and was wondering if the following is possible and if not what is the way to achive this?
<select name="select1" id="select1" size="1">
<option value="item_1">Item 1</option>
<option value="item_2">Item 2</option>
</select>

I am having a problem with the last results. I can't seem to be able to
get the input2A and input3A to appear. I don't seem to have a problem
with the show and hide after a number is entered and submitted. If
anyone can answer my problem I will be greatly appreciated with a
prize. I actually have submitted it more than once and I haven't had
anyone been able to answer it yet. Code:
INTRO: I tried to clean it up for easy reading. I hope I didn't make
any mistakes.
PROBLEM: WOW, this is some crazy sh!t. I can't get my checkbox (see
"TAGSELECTED") to print my textboxes (see "TAG#") when more than 1
number (see "VLANS") is inputed into my form.
QUESTION: How do I make my dynamic form have a dynamic input box(which
is created by checking the checkbox and calling the functionC1) inside
it and still be able to pass the values to my php page? Code:
I have made a script where you can add extra fields, and next to the row is a span that automatically displays the outcome from a calculation of three fields in that row. i.e. Q x (B - A) = total. Here is the bit that does the calculation:
function advCalc(selected) {
var result = Number(document.formmain.elements["quantity"+selected].value) * (Number(document.formmain.elements["provideamount"+selected].value) - Number(document.formmain.elements["supplyamount"+selected].value)) ;
[Code]....
On the right site there is a box with a vertical scrollbar. It´s a DIV (id="right") with an iframe in it. Maybe I´ll put a DIV with overflow:auto in it but it doesn´t matter now.
The customer wants that this 'scrollbox' takes all available vertical space. That means it should start right under the header and end above the footer.
But when there is much content and the user scrolls down the page the scrollbox has to stick under the top edge of the viewport.
Does anybody know how to realise this?
I think I can use JavaScript to get the y-position of the scrollbox and then change margin-top of the iframe or padding-bottom of DIV id="right" or whatever. Code:
I've got a PHP script that pulls some records from a MySQL database in a loop. They're images, so what I want to do is have a javascript onhover thing where a big image will display depending on which thumbnail you hover over. The code I'm using is as follows:
<!-- this bit goes between the head tags -->
<script language="javascript" type="text/javascript">
function showT(q) {document.getElementById('ima').setAttribute('src','../images/properties/'+q+'')}
</script>
[code]....
Now this javascript does work, but of course it only displays the onhover behaviour in the first element, so if there are ten img id="ima"s on the page, hovering over their associated thumbnails only changes the img id="ima" at the top of the page. It would be useful if I could have the getElementByWhatever parameter accept anything from "ima01" upwards, that way I can just append $strID onto the end of the id name and make the unique identifier that way.
How should i read the text which is inside a divison.I have the divison id,but we cannot use getElementById because everytime the page is refreshed its id is changed.
View 5 Replies View RelatedI'm attempting to submit a form via a function which dynamically creates a
hidden input:
function submitLocation(theForm) {
var e = document.createElement('input');
e.setAttribute('type', 'hidden');
e.setAttribute('name', 'location');
e.setAttribute('value', Ƈ');
var f = document.getElementById(theForm);
f.appendChild(e);
document.forms[theForm].submit();
}
The function is called from an anchor's onclick event:
<form name='form1' method='post' action='action.php'>
<a onclick="submitLocation('form1');">Submit</a>
</form>
However the function produces an input which is missing the name element:
<INPUT type=hidden value=1>
The desired output should be:
<INPUT type=hidden name=location value=1>
I am using spinbox plug-in. Its working well.
But it is not working in dynamic text boxes

This is all triggered from a, input :select. If a specific option is selected, generate a text field to enter a reason. the generated input carries an id: txComments_01/01 (this being the value pulled from the attribute "data-date".
The client only wants one per week, so if it exists already don't re-create it
I have a select element that has up to 200 items in a drop down. Each <option> element has a value 1 to 200, ie., <option value="1">text</option>, etc.
Given a list of values, such as 4, 43, 123, 199, how can I use that list to call a function and write "Selected" for those option elements in the drop down menu?

I have form where I add dynamic html element as below. In the php code via ajax I have built the full drop down list. So when I post the form in IE when I do like this $masterID=$_POST['masterID']; I am able to capture the form value. But in both firefox and chrome it shows me empty
function getMaster(entID,nextElement)

I'm having some problems understanding the append() function. What I'd like to do is select an element using it's ID and add a row to the table with a HTML form element. The table is dynamically generated using a Django template ( form.as_table() ) so I'm not able to alter the original HTML markup too much.
If I had a table like this...
I have created a form with malsup's Form Plugin wherein it submits on change of the inputs. I have set up my jQuery script to index drop down menus and visible inputs, and uses that index to determine whether keydown of tab should move focus to the next element or the first element, and likewise with shift+tab keydown. However, instead of moving focus to the first element from the last element on tab keydown like I would like it to, it moves focus to the second element. How can I change it to cycle focus to the actual first and last elements? Here is a live link to my form: [URL]. Here is my script:
$(document).ready(function() {
var options = {
target: '#c_main',
success: setFocus

For some reason my change() function is only called when the page loads. I'd
much rather it gets called when the select changes.
Here's the code:
window.onload = init;
function init() {
var new_select = new Selector('tdata','myselect','myid');
var new_select_list = new DataSource("some_list");
new_select_list.addItem(1,"One");
new_select_list.addItem(2,"Two");
new_select_list.addItem(3,"Three");
new_select_list.addItem(4,"Four");
new_select_list.addItem(5,"Five");
new_select.setDataSource(new_select_list);
new_select.formInput("form","input");
}
Selector = function(container_id,name,id) {
var container = document.getElementById(container_id);
this.node = document.createElement("select");
//this.node = new Select();
container.appendChild(this.node);
this.node.name = name;
this.node.id = id;
}
Selector.prototype.setDataSource = function(ds) {
this.dataSource = ds;
for(var i = 0; i < ds.items.length; i++) {
if(ds.items[i] != undefined) {
var option = new Option(ds.items[i],i,false,false);
this.node.options[this.node.options.length] = option;
}
}
}
Selector.prototype.formInput = function(form,element) {
var myform = document.getElementById(form);
this.input = document.createElement("input");
this.input.name = element;
//this.input.type = "hidden";
myform.insertBefore(this.input,myform.firstChild);
this.node.onchange = change(this);
}
function change(selector) {
alert("hello");
selector.input.value = selector.node.value;
}
DataSource = function(name) {
this.name = name;
this.items = new Array();
}
DataSource.prototype.addItem = function(id,item) {
this.items[id] = item;
}
and the html:
<html>
<head>
<script defer src="/javascript/selectors.js"
type="text/javascript"></script>
</head>
<body>
<form id=form>
<table border=1>
<tr>
<td>
Select:
</td>
<td id=tdata>

</tr>
</table>
</form>

I have a problem, I have a table which dynamically create <tr> elements with a unique numerical id, this is created on a while loop from a database statement, when I click on a hyperlink on each <tr> I use this:
[Code]...
So in this way, I'm sending the unique code (codigo) and I fadeToggle the <tr> identified with that specific id, it works, no problem, it display with one click, hides with another one, BUT, now I need that, when you click on a hyperlink, if any other <tr> is being displayed at the moment, close all of them, and open the clicked one, is there any way I can do this?
I'm currently working on an IE7 CSS fix for a rather large form. Long story short, I have each input wrapped in a div, all in the same class. What I need, is to have each div define a padding-right value that is equal to the width of that div. I'm fairly new to jQuery, so I'm in need of some help with the syntax. Here's what I currently have, but it keeps printing a padding-right value of "0".
$('.form_label').each(function(){
$(this).css('padding-right', function() {
var w = $(this).width();

I am echoing some dynamic content into a DIV based on form entries. The content is essentially a dynamic table, with results populated based on the user input. The user can further refine the database results by entering more data into other fields. All of this works fine. What I'd like to add is the ability to click on an <a> tag header on each column to sort by that column. I haven't gotten it to work, so I wanted to try a more simple test. I currently echo <a id='test' href='#'>Click Me</a> into the DIV set aside for AJAX response. I then setup a jquery .click() event monitor to simply alert me when I click on it. If I place this <a> tag in the main portion of the content that is static, I get the alert box. But when I put this into the content of the DIV tag generated dynamically by AJAX, it doesn't fire the alert. Is there something I need to do to 'reload' the page? Is the dynamically added content not part of the document since the entire page isn't reloaded?

The member name goes into the JavaScript to variable: member. The Problem: is when this JS tries to submit the form called "john" for example, it searches for a form called "member" instead and it fails. Is there any way to fix this? I'm sure there is a way to deal with this kind of issue but I don't know it yet.
I tried jQuery('#calculateform').children('input, select, textarea').each(function(key){ alert(key + ': ' + jQuery(this).val()); but it goes only 2time throw (for each button it has)and it SOULD list all elemts (including hidden fields). I need each element with name and value.
View 3 Replies View RelatedHow does one cause a form element to appear ONLY if a certain form selection is made before it?
That is for example say there is a form element of type Radio called "format" so only if they select format value = normal then the form input fields called URL and Name are to appear as the next choices otherwise form input field Group and checklist Places are to appear as the next choices.
