Is there a way for a JS script to detect the number of the form in which the script resides?
(i.e. document.forms[0]/[1]/[2] etc)
So:
<form action="somewhere.php" method="post">
<script>alert(//num of this form//);</script>
<input type="text" name="myfield">
<input type="submit" value="go!">
</form>
Formerly I've been replacing characters with javascript using the following code.
paramString = paramString.split("").join("<sup>");
paramString = paramString.split("").join("</sup>");
So if the user on my website types 52 it would return the following value: 5<sup>2</sup>, or just, 5 how do I detect something like this. if they enter: 5 how can I detect the number "2" and put it superscripted past the number 5. so the javascript reads this: 5 and returns this: 5<sup>2</sup>
I am working on a Phone Number Form. The link of script: [url]
Questions:
(1)I wanted to know if code this script so that instead of the phone number appearing as: (123)456-7890
So that it appears as: (123) 456-7890 with a blank space after the ")"
(2)If that's simple, is there a way to error-check it so that only numbers can be entered into the phone number input field?
I am trying to write a script that uses the IF statement to see wether or not a user clicked the back button to come to a page, and then if it's true to not let the page load and kick them back X number of pages (say 4) This is what I have so far:
<script language="JavaScript"><!--
if javascript:window.history.back == 1
{
javascript:window.history.back(4);
return false;
}
//--></script>

Here's what i have so far:

On my form i have multiple select which all have an id value total1, total2,
total3 etc so i am trying to detect how many there are and then use this to
caculate a total.
Is there a javascript reference to basically go to a form and produce a loop
which will show me how many select drop down boxes there on a form.
Or would i have t use something like
for (var i=0; i < frm.elements.length; ++i) {
form.elements.length
form_field = frm.elements[i]
and then have a nested if to detect if it is select value or has an matching
value ..
I have multiple submit buttons in a form, with the same name. ie code...
Is it possible to detect which submit button was presed, from within the onsubmit handler for the form, or would I need to apply onclick handlers for each button, and submit the form as part of the function?
I'm submitting a form (cross-domain) to an iframe and want the parent to close after submission. How can I detect if the iframe is loaded?
View 1 Replies View RelatedCan Javascript be used to detect a certain url and then "not" write some html according to that url and also detect something on the page and "then" display some html?.
Example: I'm working on a volusion site that uses asp. There's basically only one page that's changed dynamically. I would like to display some html when and only if the cart has any items in it. But also not to show up on the check-out pages.
The page dynamically displays "Your cart has 1 item in it..." when the visitors puts something in their cart.
So could javascript detect when this is displayed then write some html and then also detect if the url is showing the cart and then not show the html?
I'm trying to do this with PHP, although I think it would be easier if I used JavaScript, or maybe the same, I'm not sure.
If a user enters a value into the textbox, I want him to be able to move on only if it's a number, otherwise have text come up next to the textbox saying that he should enter a number.
I have another problem (Im not very handy with javascript).I want to check if a value entered into a form is a whole number. This means it cannot contain a decimal.I wanted to use isNumeric() but realised that allows for decimals.Is there a way I can make sure a value is simply a whole number (0-9)

I have a form and select menus. I am posting it ajax post method and loading the same page with load method as you see in codes. There is a random number genarator. I want to change this random number once a click submit. If i do not load the same page this number does not change. Therefore I use both post and load methods like in demo. However when i do like this there is a problem which is random number have been generated twice somtimes. If you click submit button successively you will see that the number on left top corner sometimes changes twice a click. Why it is so and how can i correct it.

This is what I have so far, it is a template I copied from my working E-mail validation. I'm assuming I have to make it so it's just an array of numbers but I really don't know Java too well.
Essentially I just want numbers only to be accepted into the phone field. code...

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.

I am trying to send a form value (a 15 digit number) to an external URL, so that the URL populates with the form value and opens in a new window when the user hits submit on the form.
The external URL that the form links to is in this format:[url]

View 3 Replies View RelatedI have a pretty basic HTML form, it doesn't go to a database or anything, it just gets emailed directly to the owner of the website with their customer query.However, the owner has now asked that each query be assigned a random reference number of no more than 16 digits which must also be visible to the customer.I presume this will be relatively easy but I'm a complete beginner with Javascript which I assumed would be necessary for generating the number. I've sort of figured out how to generate the number but I can't figure out how to get that number into a read-only field on the form so that it will be both visible to the client and sent with the rest of the data on the form to the owner.I've had a number of attempts but this is what I'm trying at the moment:
Code:

I am making a form using HTML and java where you enter a number and it uses an equation then spits out another number. My problem is I want to split the number you put into the form and add it up. Example You enter"457829"Press "convert"And the first step I want it to do is"4+5+7+8+2+9=sumA"Then"sumA/8"So far I can only do the sumA/8 if I manually add up the numbers then place the sum in the form, here's the code:
Code:
{
var a = parsefloat(form.NumA.value, 10);
