Retreive Url Variables And Put Into Form Elements
Apr 29, 2005
I am trying to pull two variables from a url and insert them into the appropriate text fields in a html form.
URL:
orderform.php?shape=Longboard&model=Cutter
I have this javascript, which searches the url string, HOWEVER it pulls the string into one variable. ie - Shape: LongboardCutter - INSTEAD OF: Shape: Longboard - Model: Cutter.
<script language="JavaScript">
document.form1.shape.value = location.search.substring(1);
</script>
[b]How do I get the javascript to pull the two variables seperately?[]

Consider the following XML doc returned to the xmlHttpRequest obj:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<data>
<item id="1234">
<name>Test item 1</name>
<description>some text here</description>
</item>
<item id="1654">
<name>Test item 2</name>
<description>some text here</description>
</item>
</data>
How would I go about retreiving the item node's child element's data eg. "test item 1" ?

I'm making some jQuery UI elements, and once an element is created, I want to add some custom functions and variables - I don't want to clutter up other jQuery objects by putting the functions in all jQuery objects, and obviously, the variables need to be different between different objects. However, the issue is, when I re-acquire the item, I won't have access to the variable any more.
That was probably confusing. Another way of putting it:
(function($){
var _MyUI_id=0;
jQuery.fn.MyUICreate = function(opts){
this.each(function(){
var obj=$(this)
//... code to turn the object into a MyUI object omitted to be concise
obj.MyUI_id = _MyUI_id;
_MyUI_id++;
}}
})(jQuery)
//now, create one
$('#some_div').MyUICreate({});
//The desired effect would be to give me the id in #14, instead I get 'undefined'.
alert($('#some_div').MyUI_id);
My 'solution', is to create an object variable in jQuery.fn called 'Collections'. It's indexes are the names of the new types, and each contains an object, the keys of which are the IDs of the UI elements that are converted to the type, and the values the jQueries objects. This is not only hackish, but it has a LOT of potential bugs. The code for this would look like:
This is in the 'create' function, at the end.
jQuery.fn.Collections.MyUI[obj.attr('id')]=obj;
This is outside of the create function, but within the (function($){...}) scope.
//jQuery.fn.Collections is set to {} in another file.
jQuery.fn.Collections.MyUI={};
jQuery.fn.GetMyUI(id){
return jQuery.fn.Collections.MyUI(id);
}
This will allow the first block of code to work as desired, but it inserts a whole new set of bugs. What are the common ways to achieve what I am trying to do?

I have a form and if the user presses submit, and the "password" and "retypepwd" are the same. Does anyone know how, and where to include a variable that if "password" and "retypepwd" are the same, the page is redirected to success.htm and if they are not the same, fail.htm?

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?

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.

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"

I have a table with dynamic html that contains drop down select lists
and readonly text boxes. Dynamic calculations are done on change of a
value in one of the drop down select lists.
For my first iteration the script works fine ( indicating that there
are 33 form variables ). When trying another dropdown select value, the
form elements.length is shown as 33 ( as about ) BUT the script then
crashes with a 'null value' error. I cannot access any of the form
variables - this works in all other browsers and platforms.

I have a javascript function that receives the form name, field name and value and I want to be able to spit that data back to the originating form after doing some processing on the data.
The values are making it to the function perfectly, but when I try to return those values to the form, it tells me it's not a function. I know there's some syntax problem, but I'm just not sure where!
function doThis(one,two,three){
var myFormName = one;
var myFormField = two;
var myFormValue = three;
var goHere = myFormName + '.' + myFormField;

some hidden text fields and I would like to disable all of the
categories inside the form when the page loads and only enable each
category as it is needed. Code:

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);

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;

I have a PHP page generating a list of items. I've made it so that
each one has a radiobutton with a unique value. You can click on the
radiobutton and it will change the value of a text field to the value
of the radiobutton--all that works fine!
Now, I need to also have it populate a textfield with the value of a
textfield in the row that's selected.
I can make unique field names, no problem. I think my problem is
getting the javascript written so that it recognizes the variable.
Well, see below. As it's written below, the textfield "itemqty" always
has the value "NaN" (wherever THAT comes from) no matter which
radiobutton I select.

I'm very new to JS so I am having trouble understanding how to do what is probably a simple task.I have the following script setup to parse variables from a gps mashup.
Code:
<script type="text/javascript">
this.send_query = function() {
var self = Edit;[code].....
It seems to be working just fine but now I want to store the variables from that script into a form, then submit the form so it passes all the JS vars.

I am trying to write a multiple-choice quiz for my chemistry class where ten questions are selected randomly from a block of about 100; then I want the students to click a button and grade their quiz. I have stored the questions in an array named Q and each radio button has a name property corresponding to the array entry (the buttons in Q[1] have the name Q1, etc.). I generate the exam in the body of the page between form tags using a document.write statement and all of the questions and buttons appear properly. I cannot, however, figure out how to get the value of the button that has been checked for the randomly selected questions.
As the questions are selected, I record the question number as a variable; for example �Qnumber1 = Q(random_num)�. The variable does, in fact, have the proper value (for example Q1) but when I try to read the value of the radio buttons in the Q1 set using:
document.form1.Qnumber1[0].value
it doesnt work!

[URL]
This form collects info of the customer who wishes to select add-ons that would be applied to their digital photos. Examples of add-ons:
Photo makeover
Add object or person
Crop image
Have a look at the form [URL]
Once a customer selects one of the options (Photo Manipulation or Photo Restoration for example - radio buttons) and then one or more Add-ons (check boxes in the Html form), enter their details and upload a photo, they hit the submit button and it then takes them to the PayPal checkout page where the total amount is shown. (see image below)
[URL]
The Issue:
In the PayPal page, it now shows the total amount whichever add-ons you select, however it keeps showing "Add object or person" as well as all the 5 main options (radio buttons on the form) no matter what I select. This will be an issue as I will not know exactly which add-ons the customer has selected.
complete the coding so that the add-ons show on the PayPal checkout page.
In order to send the options/add-ons the customer selects I may need to use the onX and osX variables (Where X is a number starting with 0 and incrementing by 1 see below), These can be used to set options for the add-onsthey select. The onO is the "option name" and os0 is the "option choice". So for example:
<input type="hidden" name="on0" value="Photo manipulation">
<input type="hidden" name="os0" value="Whatever add-ons the customer selects">
<input type="hidden" name="on1" value="Photo restoration">
<input type="hidden" name="os1" value="Whatever add-ons the customer selects">

Using the url test.html?a=john&b=doe
I am using the following code:
I can't seem to get an alert to show me anything. The eventual result is not an alert, but a document.write to post the url contents to various form fields for firstname= and lastname= etc.
I am really having a hard time using the document.write function, and am not sure how to employ it, whether in the same script statement or in a separate script in the body.

I have a form with allot of form items on it that posts to itself. I am trying to pass those form values to another page with out using the action attribute in the form. Is there a way to do this? I have tried jquery and javascript but coming up blank. Just trying to pass all the values at one time to another page. Seems a little difficult to me since im a intermediate javascript programmer. Here is what i am trying to do script wise. theform is the ID of the form. I have a switch statement that is based on the button pressed would get into that statement. So if one of the three buttons on the page is "excel report" it should get into that statement and pass the values of the form to another page. I have tried this:

I have a JS which validates the correct format for postcodes (or zip) on an html form - works fine.But what I want to do is to use a JS to see if a website visitor is eligible for a particular service on their postcode / zip - ie the first general part on the code. For example if they type L15****, or L16**** or L18 (where the asterisk could be anything) it pops up the alert box with a message saying "Yes eligible" but any other code returns "No sorry not eligible" - eg L19**** it returns nope.I've tried hacking the code that validates to format and can manage it for just the first character - ie the L but I'm totally lost after that. I don't know if hacking the below will work.

I have been asked to make some changes to a form that uses Javascript for the form validation. There is a 'function' that contains the variables of the various form fields and then further code to raise 'alerts' if one of the fields on the form hasn't been filled in. My problem is that for some reason I am unable to add an extra variable to this code after the field of 'County' (this will hopefully make sense when you see the code / link...) and I am stumped as to why. I am able to add variables for all of the other required fields except for 'Postcode' after 'County'. This is the case for both forms. The link is here: [URL] and the code I am trying edit is below. The issues seems to be when I add && isPostcode() to this chunk of code:-
Code JavaScript:
function checkAvailibility()
{
// re-calculate...
calculate ();
