Javascript Form Elements Defaultstate

Jan 9, 2006

Is there some way by which I get to know if the state of my form
elements have changed or not ? I mean If I have to save data which has
been entered by user in the screen, Is there some way in the JS level
that I am able to check (before i pass information to java) if the
value of the form element is same or different from the time the page
had loaded ?

So ill be able to selelct and save only those elements whose values
have been changed

I am dealing with text boxes and drop downs . .

Jquery :: Realtime Order Form - Change Form Elements Depending On Selection

Aug 25, 2010

I've been struggling trying to get a small order form to work the way I want it to. Here is a link to the live page: [URL] And here is the code in question:

[Code]...

I have two questions...

Question 1 How can I make this piece of script act a little smarter. Look at the order form, I'm catering for up to 4 people and providing lunch for them. If they select 3 people and the spaghetti bol for lunch, it's only adding $10 where it should be adding $30. Obviously this is simple multiplication but since the values in my form are prices it makes it a little tricky. I'm guessing an onselect on the first part of the form which changes the pricing of the other items would be the way to go, but how do I do this?

Question 2 The "Total Price" is placed before the <form> tag by the script. This is ok but it's not where I want it. How can I position this text elsewhere in the document?

Pass User Input From A Form To One Database Field Using Several Form Elements

May 4, 2009

I need to pass user input from a form to one database field. I'm relatively new to JS but the idea I had was to have several form elements and use JS to collect the users input and send all the values through a hidden element. What's happening is the variable names are being sent rather than the values. The code below is only passing to the next page. Limitations: I am editing an intranet site built by a 3rd party so a lot of the files we've been given are encrypted. I cannot change the method to post.

This.parentNode - Access The Elements Of The Form Without Referring To Them By ID As The Whole Form Is Intended To Be Cloned

Feb 16, 2011

I've put together what I think is an illustration of my problem at [URL] Quite simply, I need to be able to access the elements of the form without referring to them by ID as the whole form is intended to be cloned. I intended to do this using parentNode and childNodes[] together with the 'this' keyword. My understanding of 'this' in this context is that it should refer to the HTML element calling the function, i.e. one of the radio button inputs. However this gives the error "Error: this.parentNode is undefined"

JQuery :: Get Form Elements Added Dynamically To Be Included In The Form?

Oct 13, 2010

I have a grid that I'm adding rows to that include form text input boxes using addRowData. I know I can use the "editable:true" for that but I'd rather not at this time. Anyway I have the <div id=list1></div> surrounded by a <form></form>. Also statically I have a couple of text input boxes and a submit button. When I press the submit button the only parameters that show up in the POSTED data are the static ones. Is there a way to get the form elements "registered" with the form? I know I can always use javascript to extract the data and save it via an ajax call, but if there is a way to do it "correctly"

Example
var myRow = {id:"0",call:"<input name='callt"+boxNo+"' id='call"+boxNo+"' class='calls' type='text'/>",amount:"<input name='amt"+boxNo+"' id='amt"+boxNo+"' type='text' value='"+defaultDep+"'/>",residual:"",calculate:"<input type='button' class='buttons' id='b"+boxNo+"'/>"};
$("#list1").addRowData(boxNo,myRow);

Dynamically Created Form Elements Not Recognized By Request.Form?

Oct 21, 2010

I'm working with a form that has both static and dynamic form elements (add textbox, etc), and while I can access the static elements via request.form, the dynamic elements cannot be accessed. I have the dynamic elements appended within a div that lies within a table.

Here is the javascript:

Code:

function add3<%=strGoalCount%><%=strObjCount%>() {
var foo = document.getElementById('fooBar<%=strGoalCount%><%=strObjCount%>');
var numi = document.getElementById('theValue');
var num = (document.getElementById('theValue').value -1)+ 2;

Dynamically Add Elements With Javascript?

Nov 13, 2006

I'm adding people to a database. People have a first name, last name,
and a undetermined number of Cities and States with which they can be
associated. I've got a drop down box that I would like to use to
display the number of inputs to allow for city/state entry. I would
like to dynamically increase or decrease the inputs based on a user
changing the selection in the drop down box, without submitting the
script. Only the first city and state are required (which is why the
label is bold). Any ideas on the best way to handle this without
losing any potential city information that may have been previously
typed into the input (i.e. if I type San Fran into city0 and CA into
state0 and then change the number of cities to 4 - I'd like San Fran
and CA to still be populated in city0 and state0). Code:

Hiding HTML Elements Without Using Javascript

Jan 17, 2006

Here's my situation:

1. I have a web browser component that does not support Javascript
(well it does, but we've disabled it)
2. I have to display some HTML in it, where the user has a link titled
"Hide|Show Options" that can hide/show a particular section of the
HTML.

I have not found a way to achieve it without using Javascript or any
other scripting language.

Is it possible to do this using pure plain HTML?

Add Form Elements On The Fly

Aug 1, 2007

I'm creating a news section for a CMS in PHP and mySQL in which I have a text field for the headline and an textarea for the article. Instead of making the user add each article one-at-a-time I would like to know if there's a way to dynamically create/remove these elements with a button?

for instance; at page load the form contains 1 article - it has 1 text field and 1 textarea. The user decides that he wants to add 2 more articles, so he clicks the "add" button twice. Now the form has 3 articles (3 text fields and 3 textareas), each with a unique id (art1_head,art1_txt, art2_head,art2_txt, art3_head,art3_txt).

Then, I also need to have a button or checkbox to remove each article.

Forgive my ignorance. I'm not a js guy, I work in PHP. Is this possible?

Need To Loop Thru Form Elements

Jul 20, 2005

I have a dynamicly generated form (well the elements are at least) that looks something like this:

while( not end of returned records):

<input name="plan_id[]" type="checkbox" id="" value="<?=
$row_plans->planid ?>">

<input name="num_of_pockets[<?= $row_plans->planid ?>]"
type="text" id="num_of_pockets[]" value="<?=
$row_plans->num_of_pockets ?>" size="5" >

endwhile;

Basically it loops thru the table and creates a row of fields in the form that use the array identifiers '[]' so that I can loop thru them with PHP when the page is submitted.

The key for each array element is the id of the row from the database. So checkbox[] (with value "1") and cost[1] are on the same line in the form. The next line may not necessarily have cost[2] in it, it may be cost[3] or [4], depending the id from the database.

Is there some way I can loop thru these form elements in javascript?

Displaying <div> Over Other Form Elements?

Feb 11, 2009

I am creating a form in which I want a custom drop-down. Instead of displaying the normal drop-down list, I want, when I click a button, to display a dataView element directly below the textbox showing the currently selected item. What I'm not sure about is how to display the dataView directly under the textbox but on a different z-axis as the rest of the form. Currently, when I display the dataView, it pushes all the data under the textbox down to fit the dataView. I know I've seen this done with drop-down menus, but I don't know how to get it to work.

Using Form Elements In Array?

Sep 22, 2010

I am creating an array based on form elements. I then am trying to create an IF (and nested IF) statement to check if the fields are empty and then with the nested IF statement use certain fields to create mathematical functions.

So far I have this:

function QuantityMWh(form) {
var formchk = document.forms[0]
for (i = 0; i < formchk.elements.length; i++) {
if (formchk.elements[1].value == "" && formchk.elements[2].value == "") {

[Code]....

It's only checking the first field and not the second, and vice versa. i.e. if only one field has text then it passes.
