Accessing Array Named Form Fields?

I only manage to access non array named form fields.
Code:
<form method="post">
<input type=checkbox name=check[]>
[code]....
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 am facing a problem in accessing form elements and returing them.Here the problem goes:
<script language="javascript" type="text/javascript">
function pop() {
newwindow2=window.open('','name','height=500,width=500');
[code]....
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.
I am working on a page where the user will select a location from a dynamically generated dropdown list. I was able to create the php multidimensional array (tested and working) from a MySql database using the users information at login, but I'm having problems converting it to a javascript multidimensional array. I need to be able to access variables that I can pass to a number of text fields within an html form.For instance, if a user belongs to a company with multiple addresses, I need to be able to let them select the address they need to prepopulate specific text fields.
View 9 Replies View Relatedim pretty new to jQuery, but familiar with JS in general. im trying to get a dom element by id to change the read only attribute. using jQuery i'm doing the following: var field = $('#name[index][index]').
but when alerting the field value, i get [object Object] and not an inputObject as i would expect.
i can use the normal getElementById and it works as I would expect. Is this a problem with jQuery?
I need to create a form that has three questions, but the answers have to match my answers...what is the best way to do this (without DB). I was thinking create an array with the 3 answers then match the fields with the answers in my array.
View 16 Replies View RelatedFrom the these form fields I want to be able to create an array in Javascript containing the same 'codes' that feature between the option tags (not the value="X")
<select name="options-1" id="options-1">
<option value="">Select an option</option>
<option value="1">KA-WH</option>
<option value="2">KA-BK</option>
<option value="3">KA-GN</option>

for example, from the above, I want a JS array for 'option-1' that contains KA-WH, KA-BK and KA-GN; plus an array for 'option-2' that contains BADGE-1, BADGE-2 and BADGE-3. The above form fields will be created dynamically, may contain more or fewer items.
I then want to use the JS arrays to pull in images of which filenames match the 'code' in the array.
I need little help with arrays :))

I have a working example of jQuery validate working in the link below. The newsletter checkbox is required and working. However, the "colors" checkboxes are all named as an array ( ex: name="color[]" ), and so the problem lies in the validation code, where it uses the name of the element to require elements ( ex: newsletter: "required" ).
Code JavaScript:
<script>
$("#testform").validate({

I am looking for a push in the right direction for a few problems i am running into; my first problem is I have to create a script element that contains the function amountTotal which should return the sum of all the values in the amount array. There are no parameters for this function, and I have to add the following commands to it.
1. declare a variable named total with an initial value of 0
2. create a for loop thatloops through all of the values in the amount array, at each iteration of the loop, add the current value of the array item to the value of the total variable.
3. and after the for loop is completed, return the value of the total variable.
The amount array has already been created and populated in a list.js file, I had to first create a script element pointing to it.
This is what i had for my link to the list.js file and funtion :
I have my entire code written but i am trying to break it up and fix my problems 1 at a time: when i open the code, it does'nt display correctly ( which is another problem) but I ran the debugger and it says my total is undefined. ( this is in another section of my code), but I guess my function is wrong somewhere.
I have multiple fields in a form with the same name. Lets call the fields with the same name "junk_array". My first field of junk_array is a input type=hidden. All the others fields in junk_array that follow are type=text. I can reference this first hidden field in IE with document.form.field[0].value. In, fact my form works absolutely wonderful in IE 6. However, netscape 4.7 does not recognize my first field in the array as the hidden field. Netscape sees the first visible text field as the first field in the array, subscript 0. What totally and utterly perplexes me, is that, from a previous thread, I can do this and get 9999 back in an alert
box in Netscape and IE. So, this proves Netscape doesn't have some evil code that disregards hidden fields. I guess...
<body onload="alert(document.myForm.test[0].value);">
<form name="myForm">
<input type="hidden" name="test" value="9999">
<input type="hidden" name="test" value="8888">
<input type="text" name="test" value="6">
<input type="text" name="test" value="3">
</form>
I even copied these fields directly below the opening <form> tag in my form and both Netscape and IE see the first hidden field as as
subscript 0.
However, my form is much more complicated. I have tables within tables and about 30 other fields. In my form I cannot for the life of me get Netscape to recognize the first hidden field of junk_array to zed as index 0.
Somehow, If I make the first type=hidden fields visible, netscape does work nicely. Why when I toggle type=hidden to type=text does Netscape cooperate. What is happening here? Anyone else have this problem with hidden fields in Netscape? I could post the code to my form but it is
big.
The problem I'm facing is I have a form which isn't name (and no I can't name it either ). And I want to fill in the value of one of the text inputs.
View 23 Replies View RelatedThere are two input fields in a form, but only one of them is required, they are not required at the same time. Either A or B is required. ( A is required OR B is required). In other words, a user can input data to field A, or he can input data to filed B, but he can not input data to Both A and B at the same time. How to implement this constraint in Jquery form validation?
View 17 Replies View RelatedI 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 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.

Code:
testarray = [
["1", "test1", "test11"],
["3", "test3", "test33"],
["5", "test5", "test55"],
["2", "test2", "test22"]
];
How do I access the 2nd column of the 2nd row?
I tried:
Code:
alert(testarray[1][1]);
But it says undefined.
<script type="text/javascript">
function popsizes(colorcode) {
var BLK=new Array();
BLK = ["2XL","3XL","4XL","5XL","LG","MD","SM","XL","XS"];
elem = document.getElementById("selcolor");
for (i=0; i<elem.options.length; i++){
sizelist = colorcode[i];
document.getElementById("selsize").options[i] = new Option(sizelist);
}}
</script>
In an event, i'm passing in "BLK" as the colorcode param. This is creating my selsize select box with B, L, K, and undefined options until the for loop finishes. ie, its taking the passed in colorcode as a literal string, instead of referencing the array. Anyone have a pointer as to how i can access the arry, instead of the literal string?
In my HTML, I have several of the following:
<input type='checkbox' name='right[]' id='right[]' value=Ɔ' />
All are the same except the value is set differently for each one. The
reason for the [] is so I can access the checkbox values as an array on
the processing page (when clicking 'Submit');
However, I want my Javascript code to examine these objects first. My
onclick event handler function (below) is called (I get the 'hi there'
popup), but it does nothing afterward (i.e., neither 'checkbox' alert
appears, and the handler, strangely, seems to return 'true').
I suppose my problem is that I am not specifying the checkbox array
properly. I tried several variations, but I've been working on this
problem alone for several hours and am getting nowhere. Code:
I created an array, whose entries looks like this:
[41, "The bird flew into it's cage"]
[33, "He drew fire from Joe"]
[33, "Roger asked her her name"]

I have been looking for the past 2 days for a script that I can add and delete table rows.
I have found a lot but so far all of them add an input field but I desperatly need a textarea or ideally a section of input fields.
I have tried to change the code from input to text area but none of them worked.
Have you come across to a similar script.
I would appreciate any contributions.
What I am trying to do is a page where the user will add their employees details so we can order business cards for them. So I have fileds such as, Name, Tel Num, Email, Cell etc.
I have this order form where the customers can change the quantity by intput in a text field.I would like to have the text field changed with select fields, but doing so in the form, the script is not doing anymore.Can anyone have a look and tell me what to change in the scritp to accept select fields in place of the text fields.
View 5 Replies View RelatedI'm a little puzzled over the possibility of accessing an array. I've declared the previd id - in the proxy.invoke call which works just fine (we have already implemented an .each loop which also works. My problem is this - after accessing the proxy.invoke function, the previd is populated correctly with push but after the call, we cannot seem to access the previd array to make a join to a string. Here's the basics of the code.
var previd = [];
proxy.invoke("validdateIDCard", p_caregiverid,

previd.push(valcard);
}, onPageError);
var finalvalue = previd.join("|"); <-- this is where the problem lies - cannot seem to read the variable...
i have a php page in which i have a listbox as below:
<select NAME="scopeid[]" id="scopeid[]" class=sel1 multiple size=4>
<? while ($qrrs=mysql_fetch_assoc($qrrid)) { ?>
<option value="<?=$qrrs['scopeid']?>" <? if($db->isinarray($scopeid,$qrrs['scopeid']) ){ print " selected "; } ?>><?=$qrrs['scopedescription']?></option>
<? } ?>
</select>
<input type="button" name="add" value="Add" class=button onclick="Add()" style="width:40">
how do i pass the values of listbox[] to javascript?
below is my javascript:
function Add() {
Obj=(document.getElementById("scopeid[]"));
alert(Obj.value);
}
alert gives me only the last selected value and not the entire values. i.e if the user has selected 2 ,3 and 4th option, it gives me value of only 4th item instead of all three. how to do it?
Okay, so I've sorted a numerical array and the minimum is at the top of the heap with [0]. How do I keep track of the original [?] so that I can access the associated parameters?
