Multiple Array And Display - Declare A Variable Named Total With An Initial Value Of 0
Sep 17, 2010I 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.
Named Element Access By ID
Dec 23, 2005The 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.
Access A Part Of Multidimensional Array Based On A Variable That Is Passed Into The Function
Sep 12, 2002how would i build a multidimensional array? would it be: PHP Code:
var rinksAndPriceArray = new Array();
rinksAndPriceArray[0] = new Array();
rinksAndPriceArray[1] = new Array();
i've figured that out so far.
now, i want to be able to access a part of one of the arrays based on a variable that is passed into the function
the variable i'll send in will be the first part of the array ex: rinksAndPriceArray[0][0] and i'll want to return the rinksAndPriceArray[0][1] value.
ChangeYear - GetFullYear - SetFullYear Functions - Extract The 4-digit Value From The Today Variable And Store The Value In A Variable Named Year
Oct 13, 2009a.) specify two parameters for the changeYear function: today and holiday.
function changeYear(today)(holiday){
b.) in the first line of the above function, use the getFullYear() date method to extract the 4-digit value from the today variable and store the value in a variable named year.
first line
c.) in the second line; use the setFullYear() date method to set the full year of the holiday date object to the value of the year variable.
second line
d.) in the third line, use a conditional operator on the year variable. The test condition is whether the value of the holiday date object is less than the today date object. If it is, this means that the event has already passed in the current year and the value of the year variable should be increased by 1.
third line
e.) in the fourth line of the function, again set the full year value of the holiday date object to the value of the year variable.
JQuery :: Variable Scope And Un-named Functions?
Aug 23, 2010I've recently started developing javascript using jQuery and so far I'm really enjoying it.Being a professional programmer (mainly C, C++, java and python) there is one thing that's been puzzling me regarding variable scope and unnamed function declarations. Let me exemplify:
------------------------
var sum = 0;
$(xmlobj).find("item").each(function(){

JQuery :: Validate -- Require Series Of Checkboxes When Named As Array[]?
Sep 23, 2009I 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({

Form Validation For Checkbox Named As Array
Jul 24, 2005I 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[]".

Global Variable Glitch - Can Only Access The Variable On The Second Call
Dec 9, 2011I am simply trying to use a global variable in javascript, but can only access the variable on the second call. I can't find anything that relates to this through my searches. My application is supposed to query the server for XML that tells me which years and months are available to put into combo boxes. I want to store this xml in a global variable to access it later.

THISID is of course the id of the actual input which corresponds to the INPUTID of the data. Can't find a solution, what should stand instead of THISID in the iteration?

JQuery :: Can't Use Variable To Access Json Node
Jan 21, 2010why I cannot access json data by using a variable as a node name. I'm trying to grab a random quote from a .json file and display it in a div. When I access a node in the object by node name I can access the node data. However, when I try to use a variable in place of the node name (because I want to grab a random node) I get an object undefined error.
JSON object:
{
"quote1" : {"quote" : "hello, world."},
"quote2" : {"quote" : "goodbye, world."},
"quote3" : {"quote" : "out of this world."}

JQuery :: Access And Clone A Huge Array On Another Page.js ?
Aug 13, 2011I'm attempting to design my first 'just-watch-it' canvas show, which fills in randomly each time you click start. Doing pretty well, but this is where I'm stumped:
I have an array of 10,000 coordinate pairs = absolute positions on my canvas. I have this monster array on its own 'page.js' and used a <link src="template.js .. to link it in the head of my 'canvas.html'
How do I instruct my script to make a working copy of it? I don't want to manipulate the template array, but my script needs to make a clone of it ...as what? a variable? an object? I don't know what functions to use. This clone will be manipulated and have indices removed one by one as areas are filled in on the canvas.
my template.js just reads:
canvasTemplate = ['H0V0',..................,'H99V99']
Do I need to identify as an element differently so jQuery can locate it?
Each time you click for a new 'show' it needs to run a function of cashing a fresh copy of this array to operate on.

View 2 Replies View RelatedNot Able To Access Global Variable / Enable This?
Apr 3, 2010I'm trying to populate a web page with javascript. I have 2 functions. One that runs on-load so I can populate a dropdown list. The second one to process the selection when the user selects an item from the list.
I have a global variable in the top of my javascript that I use in the functions and as long as I set it in it's global scope, everything works fine. But what I really want to do is to pass this into the javascript running on this page via the code...
My question is. Where do I put this code so that I can use it to set the global variable "weekNumber"?
I've tried putting this code in the populateList function - NOPE! I've tried referencing it via window.weekNumber and this.weekNumber - NOPE. I'm stumped.
I've spent far too many hours trying to understand this without success. Can anyone help me figure out where to put this code so I can set the global variable weekNumber?
Is there a better way to do this?
