I have a form with a lot's of number of Text and Hidden Fields. I just do a simple loop to get each value for each attribute. I have about more than 2000.
if i do something simple like :
for (var i=0; i<2000; i++)
aValue = i+10;
it runs well. But if i do something like
for (var i=0; i<2000; i++)
aValue = document.myForm.elements[i].value;
it gives me 100% CPU for a long time before i submit the form.
I am trying to create a form for authorised users to upload photos to
an image gallery. I'm attempting to perform simple validation of the
fields by ensuring the fields aren't empty and that the extensions are
right. However, I can't seem to access the actual values of the fields
to start with.
If I simplify my problem, can anyone tell me why this would work in a
Javascript alert:
alert(document.form.Photo1.value);
//This outputs 'D:/images/x.jpg'
but this won't:
var photonumber = "Photo" + 1;
alert(document.form.photonumber.value);
// I get "undefined"
The reason I'm doing this is because I'm looping through a finite set
of images and need to check each one is valid.
Is it because I'm not initialising the "photonumber" string correctly?
So I'm a novice coder and have been trying to piece together a (seemingly) simple function. I want the user to be able to enter in a certain amount of time into a form, and then when they click submit, it opens a new page and closes after that amount of time.There is a very simple form on the first page that accepts input and looks like so:
<form action="onbreak.php" target="_blank" method="POST"><p class="fillable">I would like to view <input type="text" name="url" id="url" value="" size="30"/> for <input type="text" name="timeinput" id="timeinput" value="" size="3"/> minute(s). <input type="submit" value="Break Me!"/></p></form>
[code]....
HTML Code:
function makeForm(name) {
mypara=document.getElementById("paraID");
myform=document.createElement("form");
myselect = document.createElement("input");
[Code].....
I am creating a form dynamically using javascript.The form is created successfully. After creating the form before submitting the form i would like to make some check points before submission.so while creating the form i am adding the event on submit=call function for validation .THe function is called successfully but i am unable to retreive the form values in the validation script

I have:
1 form on the page. (no name, no id value set.)
3 hidden form elements named: catalog, vwoidc, oid
!!! I can only include the javascript right after the body tag. The
form is found near the end of the loaded page.
<form action="actionURL" method=post>
<input type=hidden name=catalog value=store>
<input type=hidden name=vwoidc value=69a6e1deb02417250691>
<input type=hidden name=oid value=60323></form>
Everything I've tried needs to have the javascript executed after the
page has been fully loaded.
Is their a way of iterating thru each tag within a form and returning the
value given in the id property, by that I mean the below html would return
the values idBoxOne, idBoxTwo, idBoxThree from the FormXX form.
<form name="FormXX" method="post" action="default.htm">
<input id="idBoxOne" name="bxOne" type="text">
<input id="idBoxTwo" name="bxTwo" type="text">
<input id="idBoxThree" name="bxThree" type="text">
</form>
Up to this point I've only used JavaScript to change CSS properties,
innerHTML and outerHTML so I'm rather new to the game.
Is there a way to retrieve the DOM element number in a form? For instance if I had 5 checkboxes with the same name and an event was fired to gather data, could I determine the DOM element number for each checkbox checked? I know this may seem like meaningless information, but I need it to do some other work on the page.
View 4 Replies View RelatedSo, I have a form that, when the user clicks on a link, uses J/S to generate extra form fields for extra information. I can retrieve the value of the dynamically generated fields using $_POST in I.E., but it doesn't work in Firefox (no value is returned). Retrieving values for the static fields is fine in both I.E. and Firefox.
Here's the code - is there a function I'm using that could be replaced with something more friendly to Firefox?:
<script type='text/javascript'>
var i = 1;
function addArea() {
var newArea = addElement();

I am having difficulty with creating a function that uses a For Loop to pull in two unknown variables and subtracting the first number from the second number. The subtraction occurs but I always get a negative number. This exact same function works correctly when adding but does not when I use it for subtracting to values. Here is what I have so far:
function calcDep1()
{
dblTotal = 0.0
for (i=8;i<=9;i++)
[Code]....
I have worked with it for several hours and also changed the equation to reflect dblTotal = dblTotal - dblValue but it still evaluates to a negative number. The two test values I used are 100 - 50 which should equal 50 but the answer always comes out to -150.
I have a struct like this:
Code JavaScript:
function Sampe(name, value, unit)
{
this.name = name;
[code]...
I then have an array of instances of this struct. I'm trying to create a search feature and need to loop through each instance of the struct in my array. Then I need to loop through each value in the struct and check it for a substring. If a substring is found the entire struct instance is printed and the search will skip to the next struct instance. Right now my loops are not working properly. The loop below with 'item' is not correct as 'item' just prints out a number (should be a text value).
Code JavaScript:
function searchView(text)
{
document.getElementById("searchResult").innerHTML = "";
[code]....
I have a bunch of input fields, each which will have a numerical value. There can be any number of input fields in the form, and that number will vary depending on what the user has selected prior in the application.
So basically I created a loop that goes though all of the INPUT fields within the form. How can I have it find the value of each field and add them all together, then return to me the total? It'll need to be made into a variable, but a simple alert with the total value will give me enough to work with.
Having a small problem with writing out the matches from an array using a For loop.
I have two arrays, lets say arrayA and arrayB. In arrayB are numbers which are a number of miles, ie 1,2,6,4,5,6,6. And in arrayA are the days of the week. Each day of the week is associated with a mileage, ie Mon = 1, Tues = 2 etc.
My script has found the largest mileage in arrayB. Next I have to find the days of the week that match this highest mileage and write these out, along the lines of "The highest mileage was 6 run on Wed, Sat, Sun."
I have managed to get a For loop to work with this BUT..... I can only get it to write out the first instance of the day the match is found. ie "The highest mileage was 6 run on Wed,"

The Script below generates a sudoku (9 by 9) table and displays the table on screen.
what I am trying to do is to get a string of numbers entered into the text field labeled "enter values" on the page below the table, into each cell box of the sudoku table when the button labelled "load" is pressed. This would fill the sudoku table with characters, one character (from the text field) to each of cell boxes in the sudoku table.
It requires using a for loop, I tried using one in my function (g) but it doesn't work,..

Using JQuery how do you loop through fields taking a value from each one and multiplying with a specific value.

I can't (just before this line) assign 0 to each array item - to get it defined because if the user goes back in and adds more, it will always reset the number back to 0, which is not what I wanted.
I tried adding an if..else statement instead, but cannot figure out how to get that to work?

I have a form that gets values that a user has selected from a list menu field, that end up like this added to the URL:[url]
Instead of the Field being mentioned more than once, how can I have it where it could mention the field once with the values coma separated eg:[url]
Would I use JS to change the URL? or VBscript?
I have 4 text boxes that are supposed to load 4 seperate values of data from one field in one table from a database. The field is called interface_cropsettings (from the interface table) and these values have been concatenated and comma seperated in this field.
Code:
Once the form is filled out and saved, the data is inserted into the database and the values from these 4 text boxes are concatenated, comma seperated and inserted into that one field correctly.
(Example)
If the 4 text boxes have the following values:
In the database field they become:
However, if the form is closed and then re-opened, each text box displays the entire database field rather then each value seperated in the corresponding text box.
(Example)
All 4 text boxes display this:
I already know why the data appears like this in the form, my problem is that I'm not sure how to write the javascript to seperate the values into the correct corresponding fields, assuming javascript is what I should be using!
Also, this is kind of irrelevant but just in case you're wondering, this form is part of a cold fusion application!
