I'm very new to javascript and I have a question. I'm creating a calculator. This calculator has a memory function in it. When people inserted a value in the calculator then the user can save this value with button "M+". When the user wants to use this value again he can simply paste it into the calculator with button "MR".
This works fine, however I'm working on a function that will remember the different memory value when a user clicks on the button. So if the memorized value is 5, and the user will click the button "ATA" (add to array) it will create the value "5" into an array (which will be the value of array[0]. When the user remembers a other memory value, lets say 9, and clicks on the button "ATA" again it will create the value "9" into the same array (which will be the value of array[1]).

My current method doesn't seem to work, it only saves the first value.
// ATA function saveAta() { var saved = new Array(); saved.push(m); // variable m is from the function of M+ }
I want to create an associative array dynamically pulling the index values from an array (propertyArray); Associative array is created inside create function and then returned. But after it is returned, I cant use index names to retrieve values. It returns undefined as below code shows.
Code JavaScript:
var propertyArray=["a","b","c"]; function create(){ var array=[];
function read() { var numbers = new Array(); for (i = 0; i < field.length; i++) numbers[i] = document.test.checkboxName.value; var counter=0;
[Code]...
I want to read the values of the checkboxs and store the vlaues into an array (there are more than 1 checkboxs) the form name is text and the names of the check box = checkboxname
This one is throwing me off! Either I am making a stupid mistake or I'm doing it totally wrong I have an array, and I am trying to select unique values from it and assign it to another array. Here is the code:
Code: var flag; for (i=0;i<=pdfs.length-1;i++) { flag = 1; for (j=0;j<=pdfs2.length-1;j++)
[Code]...
The problem is that the if (pdfs2[j] == pdfs[i]) statement ends up never being true. There are URL's to pdf files in the array. On the other side, if there is a much easier way to select unique values from an array, please feel free to point it out.
With Java script when a user hits submit on a form on my site, is it possible to take the values from the form and submit them to another form on another Url without the user who submitted the form on my site knowing?
I need help with javascript regular expressions.I have a text box in which user can enter only 4 types of values.
1) Varchar(n) where 0 < n <=80. Ex: Varchar(20) 2) Char(n) where 0 < n <=80. Ex: Char(20) 3) numeric(x,y) where x>y and 1<= x <=35 and 0<= y <=15. Ex: numeric(20,6)
If the text box value doesnot match this pattern, we should throw him alert message.
I have a form which contains a few drop down lists.The contents of the dropdown lists are dependent on each other and are populated via php scripts which are called each time a selection is made or changed by the user.When the view results button is clicked in the form I need the user to be directed to a specific page based on the selections they have made.The url of the page they need to be directed to is really based on what has been chosen in the first dropdown.
The subsequent dropdowns form variables that I need to be sent to the page so that the data the user sees on that page is relevant.ie if the user has chosen bikes then a specific manufacturer then a specific price range the page they will be sent to will be the bike.php page with all the manufacturer specific bikes in their chosen price range visible. Can anyone tell me the best way to go about doing this please?I had thought about using the php header script along with an if statement but how do I then go about getting the variables sent to the page to be recognised?
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 Ɗ" 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.

I'm adding the ability for the user to input his own values into 6 input fields, some or all of which may be left blank. I have already an array populated (thanks to Paul Wilkins) with default values. How do I get the user's values into that array so the calculations will be performed on it?I got this far, but was unable to understand the problems brought up by JSHint.com.
User enters integer values into an editable gridview. JS is meant to keep a running total in the gridview footer template while user enters the values. User clicks 'Save' button. The values are saved to database table.
Problems:
1. JS does not keep a running total if there is already values saved in a database table. (Explaination: If user clicks 'select all', the previously added values are loaded. Can edit these and running total works. But, if user is entering numbers for the first time into a blank editable gridview, the js does not work).
2. Cannot access label in gridview footer template. 'Object reference not set to an instance of an object'. If label is placed in normal gridview row, it is fine. However, it needs to be in the footer.
javascript function
Meant to be in footer template but placed in normal row for now:
I have an array that is made and modified in a function. At the end of the function I want to have the array to be sent as a file to be downloaded to the user. How can I go about doing this?

Let's say I want an array of all the values for checked checkboxes onmy page. How do I do this?This:$('input:checkbox:checked').val()..only returns the first value. Is there a function that will return ajavascript array of values?
So I created a javascript to get all the selected values in one variable ... But whtever I try the values don't come .. I tried alerting at different places and wht I see is tht it don't even go into the for loop ...
Code:
<SCRIPT> function content() { var retval = new Array(); for(i = 0; i < document.form100.state.length; i++)
i created multiple checkboxes with similar name. and i want to retrieve each single value and do some calculation according to each value. i've tried count, split but still cannot find the solution.
Code:
var total_price = 0; var brg = new Array(Request.Form("brg")); var qty = new Array(Request.Form("qty"));
I'm having problems with selecting values from array.I have a dropdown box where you choose what fruit you want to buy.When selected the array should assign 2 values to that fruit.Here's what I have.. I added comments.
Javascript part:
<script type="text/javascript"> function Fruits() { var selectfruit = newArray( //assigning values to fruit selected from dropdown box newArray("Banana", 1, 1),
I am having a problem to add numbers store in an array. arrayValues[0][0] = 1; arrayValues[0][1] = 2; var col = 0; var sum; for ( var row = 0; row < index; i++ ) sum += arrayValues[col][row]; My result is ==> 12 it is defining my sum variable as string. Even I try do do this var sum = 0; to define sum as numeric variable. my result was ==>012.
I need to pass an array of client side events to the next page. Here my user would perform a few events which would be stored in a javascript array, upon completion a submit button would be used to post all that data to the next page.
An example of such a process is listed below, returning that array back to php so that I can post it to the next page. I am trying to populate different entries made into textbox into the array arr. And when I would click the submit button, I want to post that array.
<html> <head> <script type='text/javascript'> function retText(form)
[Code]....
I want to return that arr back and on post I want to send that array to the next page.
