Retrieve And Pass Information To And From HTML Forms

Jan 7, 2009

This question may appear opposite of most, but I'm learning JS using a book and I can't understand why/how this particular code works. I'm working on simply retrieving and passing information to and from html forms. This is a very simple script that will change what is selected in the drop down box depending on a button push.

Here is the script:
Code:
function flip(pizzatype) {
if (pizzatype.value == "Veggie Special") {
document.forms["pizzaform"].topping.value = "veggies";
} else if (pizzatype.value == "Meat Special") {
document.forms["pizzaform"].topping.value = "meat";
} else if (pizzatype.value == "Hawaiian") {
document.forms["pizzaform"].topping.value = "hampineapple";
}}

And here is the form's html:
Code:
<form id="pizzaform" action="#" onsubmit="return false;">
<p>
<input type="button" name="veggiespecial" onclick="flip(veggiespecial)"
value="Veggie Special"/>
<input type="button" onclick="flip(meatspecial)" name="meatspecial"
value="Meat Special" />
<input type="button" onclick="flip(hawaiian)" name="hawaiian"
value="Hawaiian" />
</p>
<p>Main Topping: <select name="topping">
<option value="cheese" selected="selected">Cheese</option>
<option value="veggies">Veggies</option>
<option value="meat">Meat</option>
<option value="hampineapple">Ham & Pineapples</option>
</select></p>
</form>

The way I see it is the button onclick will call the flip function and pass it a var, for example "veggiespecial". I understand the code that will perform the actual change on the drop down menu. What I don't understand is the if statement.
if(pizzatype.value == "veggiespecial")...
Shouldn't it be just (pizzatype == "veggiespecial")?
Why does it have to be pizzatype.value? Where the heck does the .value come from???

Hidden - Retrieve Information By Downloading The Source In My PHP Program

Apr 16, 2010

The link below is the result of a product search on a website. It displays 2 results. However, the actual results (picture & information) that are displayed on the web page are not present in the "Page Source".

For example, if you search the page source for the string '860723' (which is one of the product numbers visible on the web page) it is not there. What is going on here? It looks to me like dummy images & information in the HTML are first loaded by the browser, and then that dummy info gets replaced by the real information via a javascript function. Is that what's going on?

[url]

I'm trying to retrieve that information by downloading the source in my PHP program. The problem is that the information I want isn't present in the source. It stands to reason that the information is somehow being sent to the browser because I can see it..

Pass Control (text Field) Values From One Html To Other Using Hidden Variables.

Mar 7, 2007

function submitPartsForm(str) {

var count=document.getElementsByName("partId");
for(var i=0;i<count.length;i++)
{

document.mylist.myNum[i].value= document.getElementsByName("partNum")
(i).value;}

document.forms["mylist"].submit();
}

myNum[] is a hidden variable and partNum is the name of a text field
that has many instances i mean there are many textfields with the same
name so it forms a column in a data table.

Pass The Current URL As A Hidden Field Through HTML Form

Dec 16, 2011

I have an HTML contact form on many different pages of a web site. I need to know which page the user was on when they submit the form. I need to pass the URL of the current page as a hidden field through the form when it's submitted. Do I need to add javascript to the header to call a function pulling the URL and then a secondary function to place it in the hidden field's "value" attribute?

HTML Form - User Select To Set Two Values?

Jul 4, 2005

I need to use Javascript or similar to do this, but not certain. I want to set up a form in HTML to sell photo prints. I'd like the user to be able to select a print size (eg 4x6 or 5x8 or 7x9) and as a result, two values are set:

1. the print size in text (eg &#394;" x 6" print')
2. the price of the print (eg $5.00)

How do I code my form so that two values are set at once, and if the user changes their mind (eg selects 5x8), the two values are set again.

Extract Information Which Is Located In A Predefined Area On The Screen From A Java Platform?

May 21, 2010

Is it possible to extract information which is located in a predefined area on the screen from a java platform?

For example, there is java based platform which I can see on my screen.

This platform contains numbers/letters.

The location of these numbers/letters does not change, i.e. the script would not need to be adjusted if the field, which contains the info, would move.

Lets assume the screen would look like that:

The info between the fields would be clearly separated.

Now I would like to extract the infos from all the fields and paste the info for example in EXCEL so that I can see "Valerie12345" in .xls field A1 / 12.20 in A2 / Love in B1 etc...if that is possible to extract?

var oxml = document.getElementById("xmlfile");
var oDom = oxml.XMLDocument;

<Name Id="109" userid="B25" level="2" selected="0"/>
<Name Id="120" userid="C29" level="1" selected="0"/>
<Name Id="133" userid="D03" level="1" selected="0"/>
<Name Id="132" userid="D3 " level="1" selected="0"/>
</root>

What code do I need to write to traverse above XML code to retrieve those userid value only when the selected=1???? And display the userid "A2" and "A5" with window.confirm in Javascript

Pass Option Values To Superfish Only If The Browser Is IE6

Oct 21, 2010

I want to pass option values to superfish only if the browser is > IE6, so I thought to do this:

Code:
$(document).ready(function() {
$('ul.sf-menu').superfish({
if ($.browser.msie && $.browser.version > 6){
animation: {height:'show'},
[Code]...

but it isn't right. It breaks the javascript, and doesn't run at all. Anyone have some clues or answers for me? I don't use jquery or javascript enough to figure it out.

When A User Enters Information In Those Two Textboxes And Click On Submit, The Information Is Sent To A Function?

Oct 29, 2010

I have a HTML form containing two text box controls in it and a submit button. When a user enters information in those two textboxes and click on submit, the information is sent to a function in Javascript. In the javascript, the information from those textboxes is stored in a javascript variable. The problem is as follows:When I am inputting string text in the html text boxes and in the javascript when I am trying to print those values, it is giving me out an error saying NaN. However when i input integer values in the text boxes it is printing those numbers. Is there a conversion that I have to do for the string to be printed. I am new to Javascript and need your help. This is a basic code of Javascript. Below is the code that I have.

<html>
<script type = "text/javascript">
function square(form)

Hidden Div Pass On Form Data?

Sep 16, 2011

Say I have a form so long that i want to group sections by category and have them expandable, using css to display:none or display:block these groups. If a user selects an option or two in one of these divs, then fills in some fields, then hides the div... is it going to cause problems when they submit the form if the div is hidden?

edit: what if we add validation into the mix. What happens if a field in a hidden div does not pass validation?

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.

Jquery :: Retrieve Value Of Html Form Drop Down Menu?

Apr 9, 2009

I'm trying to accomplish something unique that I am not finding any examples for in web searches.I have a webpage with arrow pictures that I will set up with a clickable link that will send http arguments to a php script.I need to grab the selected value in one of the drop down menus on that same page and send that as one of the html arguments when clicking on one of the arrow buttons.

Right now those drop down lists are just html form controls, would this all work together better if they were instead javascript drop down menus? I really want to build this page the best way for it to be built and I'm not afraid to make changes if there is a better way than what I'm using now.

JQuery :: Retrieve Server Response After Submitting Form In HTML?

Dec 28, 2011

I have designed a form as below

<form action="https://checkout.google.com/api/checkout/v2/checkoutForm/Merchant/XXXXXXXXXXXX" id="BB_BuyButtonForm" method="post" name="BB_BuyButtonForm" target="_top" >
<input name="item_name_1" type="hidden" value="Test Product"/>
<input name="item_description_1" type="hidden" value="Test Product of my cart"/>

[Code].....

On hitting the button one new window is getting opened with response URL from 3rd party(in this case Google Checkout). But for me i need to open this in a inline-popup (lightBox, ColorBox etc...) rather than new window. In the form definition, i have replaced mymerchant_idwith 'XXXXXXXXXX' for privacy purpose
