View 23 RepliesI was using jquery-1.2.6 and now, I started to use jquery-1.3.2, and I get my first "difference": when I use the wrapped set operation $ (':input[@name=submit]') with jquery-1.3.2 it returns all input fields, but if I use it with jquery-1.2.6 it returns 0 (as espected). Is it an error with 1.3.2 version?What do you think I'm doing wrong? This wrapped set is used by "jQuery Form Plugin" and, if I have file uploads I get the alert 'Error: Form elements must not be named "submit".' from the function "fileUpload" of this plugin.
View 3 Replies View RelatedThe problem goes like this:
For each element in the currently loaded markup page that has an 'id'
attribute, elements can be accessed like-
var elem = document.getElementById("foo"); - ("foo" is the 'id')
now i want to implement a shorthand method which can give me the
element just by this:
var elem = document.foo; -("foo" is the 'id');
For this , i will have to add properties to the global "document"
object for each element in the currently loaded page that has an
attribute. These properties should be added when a page is loaded , and
should be removed when a page is unloaded..
How can i dynamically add and remove property to an object.
I have ONE page which consists of php, html, and javascript, all on the same page. I have 3 different listboxes on a form, their named id's are: "strike", "grapple", and "strength". I have a span tag named id as: "pa". I Have a variable which is constant and named $totalValue and its vale is: 30, I have another variable named: $availableValue which will get its initial value from $totalValue. What I want to do is this, a user will choose his/her first list box. When the uses clicks the arrow on the listbox it drops down filled with values to choose from, these values come from the $availableValue variable and should be displayed as: 1,2,3,4,5,etc,etc,etc, after the user makes their selection the value of $availableValue is decreased by the amount of the user's selected choice and the value of the $availableValue is displayed on the html part of the page in a span tag.
The user will then choose his/her second listbox, upon clicking that arrow the listbox drops down displaying the REMAINING values from $availableValue variable and displays them as: 1,2,3,etc,etc,etc, after the user makes their selection the value of $availableValue is decreased by the amount of the user's selected choice and the value of the $availableValue is displayed on the html part of the page in a span tag. The user will then choose the last listbox, and upon clicking its arrow the list drops down with the LAST REMAINING values from $availableValue and will be displayed as: 1,2,etc,etc, after the user makes their selection the value of $availableValue is decreased by the amount of the user's selected choice and the value of the $availableValue is displayed on the html part of the page in a span tag.
The user should be able to choose which ever listbox he/she wants as their first listbox. So for argument's sake lets say the user chooses listbox "grapple" first, but of course the user could have chosen any of the 3 listboxes first, but he/she choose "grapple" first. The "grapple" listbox should fill with values 1 to 30, ex: 1,2,3,4,up to 30, the user selects value 5 from "grapple", the $availableValue variable will decrease by 5 and the value of $availableValue is displayed in a span tag. The user then chooses listbox "strength", its values should be filled and displayed with values from 1 to 25, the user selects 8 from "strength", the $availableValue variable decreases by 8 and the value of $availableValue is displayed in a span tag. Finally the user selects listbox "stamina", it listbox displays the values from 1 to 17, the user selects 17 from "stamina" and the $availableValue variable decreases by 17 and the value of $availableValue is displayed in a span tag. All this should happen BEFORE I submit the form via php code.
The code below, including the html, is ALL on one page named: createfighter.php
<?php
$totalValue = 30;
$availableValue = $totalValue;
$action = $_REQUEST['action'];
$strike = $_POST['strike'];
$grapple = $_POST['grapple'];
$strength = $_POST['strength'];
?> .....
I have a number of checkboxes and radio buttons in an HTML form that are named as arrays, ie.
<INPUT type="checkbox" ID="i1" VALUE="MILK" NAME="Q1[]">
<INPUT type="checkbox" ID="i2" VALUE="SUGAR" NAME="Q1[]">
<INPUT type="checkbox" ID="i3" VALUE="BISCUIT" NAME="Q1[]">
I need to keep the 'NAME' as an array as above because of the form processing that is used after submit.
I was really hoping to use Javascript to validate the form and make sure that each checkbox group has at least one option selected , but my javascript messes up because the 'NAME' is Q1[] as opposed to Q1. I had been using:
<script>
function validate() {
if (!(mainform.Q1[0].checked || mainform.Q1[1].checked|| mainform.Q1[2].checked)) {
alert('Please answer question 1.');
event.returnValue=false;
}}
</script>
but this only works when I name the checkboxes NAME="Q1". Is anyone aware of how to get the validate function to work (or another way of validating the form) even when the checkboxes and radio buttons are named like NAME="Q1[]".
I only manage to access non array named form fields.
Code:
<form method="post">
<input type=checkbox name=check[]>

I have come across a very interesting problem that seems to be impossible to solve. Basically a web application that I am working on relies on a JavaScript function called go to change the input named view to the page name and submit the form. This form's type is post, so no values are included in the actual URL string. There is also another input called action and it's value is view. This is to tell the application that the user would like to view a page. The problem is because of the variables being of method post, page refreshes and back and forwards return errors because the post variables view and action aren't sent with the required data. To somewhat solve this problem I have created a feature that tells the application that if the post value page is empty then to try and get a GET var called page. To insert this var into the go javascript function I simple add this code
document.go.action = document.go.action+"&page="+page;
This line basically adds &page=[page] to the action of the form. The problem is, this code doesn't work because action is also the name of a form element. Referencing document.go.action refers to the input element named action and not to the form's action. Changing the named of the action input value is out of the question (Way to much changing of code, and possible room for error). What can I do to change the action of the form without referencing the input named action. Here is my go form and the JavaScript code:
<form name="go" action"index.php?sid=123" method="post">
<input type="hidden" name="action" value="view" />
<input type="hidden" name="view" value="" />
</form>

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

I have a javascript here for adding my div element to my registration form,Adding the div element is easy, but it shows on the bottom of my form. I cant make it as the first child element of my form...This is my code
var _form = document.getElementById('registration_form');
var errorDiv = document.createElement('div');
errorDiv.setAttribute('class', 'confBox');
[code]....
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.
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 am putting the following source anchor code but cannot get the expected results in Internet Explorer.
<a href="#selected"><button type="button" id="button" value="button">Content</button></a>
Destination anchor code:
<span style="position:absolute;"><a name="selected" id="selected"></a></span>
I use a subroutine to popup windows in my sebsite. It looks like this :
function poplink(filename)
{
filestring = filename + "htm"
LinkWindow = window.open(filestring,'LinkWindow','');
}
Filename is just the extensionless web page name e.g. "Addresses"
Problem is of course every window popped up will replace the previously
popped up window and in the case of a popped up window popping up a window
the new window will just replace the calling window.
(Please, no lectures on popping up windows, I need to in my particular case
and here I'm just stripping it down to the bare problem for claritie and
simplicities s sake)
I'd be happy if I could create a new window handle each time so that all my
popup windows will be unique. If it could be the filename that would be fine
e.g. instead of the window handle variable being "LinkWindow" it would be
"Addresses". Is there some way of making the variable I assign the new
window to a variable? All I can come up with is somehow having LinkWindow an
array of window handles and just keep incrementing it e.g.
LinkWindow[100]; // 100 is more than enough windows for a typical session
LinkWindowCount = 0;
function poplink(filename)
{
filestring = filename + "htm"
LinkWindow[LinkWindowCount] = window.open(filestring,'LinkWindow','');
if (LinkWindowCount < 99)
LinkWindowCount++;
else
LinkWindowCount = 0;
}
What would be the correct syntax for creating LinkWindow as an array or is
there a better way of accomplishing the same thing?
I use named anchors to take users to specific parts of a long page. But I
want to add some processing and do some things with my nav bar when users go
to certain sections delineated by named anchors. I understand that the
anchors array creates an element for each anchor in the page when the page
is loaded, but how do I identify which anchor is currently being viewed?
Here's some pseudo code:
if (document.anchors.name == "section_B") {
then do this or that
}
But what do I test to determine the current anchor name?
What about using id's instead of names? Can the anchors array return
anchors created with id's as well as names? Would this be of any benefit?
When are named elements written with script accessible to script?
<html><head><script type="text/javascript">
function ready() {
alert( document.getElementsByName("div").length );
}
</script></head>
<body onload="ready()">
<script type="text/javascript">
document.open();
document.writeln( "<div name="div"></div>" );
document.close();
</script>
</body></html>
IOW, why are there 0 elements named div at the time the <body>
element's onload handler is invoked? When can I retrieve this named
div from the document hierarchy?
This exercise is necessary since code I have written using the DOM
(that works) has to run on God-forsaken browsers such as IE 5.1 for
Mac whose support for the DOM is spotty at best.
How come none of these work :
document.getElementByID("repondant(1)").value;
document.forms.ajouterunelement.repondant(1).value;
how can i get the value of a field that is named repondant(1)?
As title says I need to create variable named with value of other variable! So is that possible?
What exactly I need is something like this:
for(var i=0; i<11; i++){
var Img[i] = ""
}
I have a little problem that doesn't seem to be working. I'm trying to access a variable using its string name which is passed when the function is called Code: ie:
function a(varName, other crap...) {
document.getElementById("sometag").innerHTML = ['varName'].somevalue;
}
// I would call this function like so...
a("temp1", othercrap...);
The variable temp1 is set in another script file. I don't specifically know which variable I will be passing to the function a(), all I have is its string representation. I can access the values of temp1 if I specifically call it but I can't seem to figure out how to call it dynamically.
I have a form in my webpage and i am referring to the form element as formname.elementname. But when i select 5000 records from one screen and goes to other screen the form in the new screen stops recognising its element. If i do not select 500 records from screen on and directly going to screen 2 the screen works perfectly fine. Any Known bug with i think.

Based on this logic, I'd like to show/hide the ID tag based on the values of a drop down list and another textbox. They both work fine but the problem I'm having is that each can cancel out the other. For example, if the 'txtPercentOther' textbox value is 3 and the drop down item has a value of 2, the ID tag is shown which is fine. But if I were to change the drop down list value to something else, it'll hide the ID tag, even though the other text box still has a value of 3 which means the ID tag should remain shown. I'm wondering if I maybe need to name my function so I can call the other in each.
I've been using jQuery for some time now but this is the first time I've run into something odd. Currently I'm developing a Theme for Concrete5.4.0.5, which automatically includes jQuery 1.4.2 - meaning, I can't use any other version of jQuery, that said: here is my problem.
I've got the following HTML (heavily simplified):
<nav id="mainNav">
<ul>
<li>Home</li>
<li>Text
<ul>
<li>Subnav</li>
</ul></li>
<li>Text
<ul><li>Subnav</li>
</ul></li>
</ul></nav>
<section id="contentWrapper">
...
</section>
And the following JS-jQuery Code (original, not simplified):
function hoehenAngleichen(){
if($('#mainNav').height() > $('#contentWrapper').height()){
$('#contentWrapper').height($('#mainNav').height());
}}
$(window).load(hoehenAngleichen);
/* works fine until here */
$('#mainNav li').bind('onmouseover onmouseout', hoehenAngleichen); //will not trigger
I want the "hoehenAngleichen" function to be triggered whenever someone is hovering or leaving a li-Element. But this code seems not to bind the events with the named function properly.
I have a few divs with the name
