How can I use JavaScript to count how many text fields are in an array of text fields? (example below)
HTML Code:
<input name="option[0]" type="text" id="option[0]" value="" /> <br />

I just want to create an array of numbers counting from 1 to a given number.
At the moment I have the for loop running like this:
var i=0;
for (i=1;i<=10;i++)
{
if (i == 1)
[Code]....
This outputs 1, 2, 3, 4, 5, 6, 7, 8, 9, 10
How can I put this output into this variable: 'var ids' so I get out
var ids= [1, 2, 3, 4, 5, 6, 7, 8, 9, 10];
How do you count patterns in record fields and create an array of it?For example:Searching in (using my example below) currently gives me multiple outputs of
0 0 (**in** seen at index 0 of book 0 title record)
0 13 (**in** seen at index 13 of book 0 title record)
1 19 (**in** seen at index 0 of book 1 title record)

I am trying to figure out how to make a random number I can plug into a script count down from that number at certain times of the day until it reaches 0. I would like it to reset itself at midnight every day. I'm trying to make it work with a script I found on here that resets itself at midnight every day. So instead of it counting down too fast, it would count down to the next number after a randomly generated number of minutes until it reaches 0. But it wouldn't necessarily have to end at 0 at midnight. It could go from 845 to 323 at the end of the day at a slower pace. Is that possible?

Code:
array = ['1, Old Man, Old Man','2 Black Sheep, Black Sheep',....]
should the text strings be in double quotes("")?
Code:
array = ['1, "Old Man", "Old Man"','2 "Black Sheep", "Black Sheep"',....]
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.

I want a looping number, the number will start at 200 and it must end at 900, the loop format is like a.. from 200 it must increment but 1 every second and stop when it reach the 900, the counter must start when the page is loading or after loading.

I have seen this addressed in a few other threads, but it is first of all not exactly like my problem and also, the language of the explanations is not simple enough for me to understand.
I am trying to make a form that has 1 box that asks how many designs a customer wishes to order, then based upon that number, reveals that many pairs of text boxes below; one should be with the label, �name of design, while the other should be with the label quantity of design. That way, if a user enters 4, four pairs of these boxes will appear, asking him specific names and quantities
If I set up a variable quantity to the value of the text box, I think I should be able to loop like,
for x=1; x<=qty.value; x++ but then I am confused about how to make the thing render the text boxes. My primitive knowledge tells me I could do something like document.write. But on another thread I read I saw that I could also use

I feel stupid for asking a question about searching arrays, when there's a very similar thread that has been answered just recently on the first page; however, I'm still having trouble contemplating my own scenario.Basically, my program prompts the user for the length of the array and then asks the user to fill the array with words.I want to confirm if the user wants to search the array for those words. If so, the user will then be prompted to enter the word he wishes to search for; if found, the location of that word will be reported and the number of times the word has been searched for will be kept track of in a separate array.Here is what I have so far:
/* -- phase 3 ------------------------------------------------------
search for words the user asks for

Is there any option not to use an array in counting the checks on checkboxes? Code will be integrated into an ORACLE database. I'm trying to catch up same output as stated below;but whenever i integrate it to Oracle database it doesnt work. I am a beginner in PHP programming.

I have used this piece of code which is working great. It allows me to add different items from combo boxes to my order form. The problem is that i dont know how to extract the data from my db to display in a form view when i want to amend the i.e the number of items. Each record has a different number of items in it but are all lnked to one id. Is this possible to do. Any help on this would go along way.

A while ago I queried how to count total characters in an output document and never really got anywhere. this query builds on from that. basically what I need to do is as follows.
- Using a basic input form, gather information.
- Populate strDoc with the info.
- When the button is clicked, the strDoc is populated and formatted and displayed in a popup window using:
What I'm trying to do is create a function that will count all characters in the strDoc (including spaces/LF/CR etc). If the total of the output doc is > 3800 characters, then the function will separate the doc into chunks no greater than 3800 characters and display each chunk in either a different window or a single window labled in order of chunk (ie. 1, 2 or 3).
This is way beyond me at this stage, but is critical to a project I'm working on at the moment.
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.
I am trying to count the characters in a text area in a form for sending sms from web to phone. Bulk sms standard is: maximum sms pages are 7 i.e 1071 characters; page 1 contains 160 characters, page 2 contains 146 characters and the rest 5 pages contains 153 characters.
Here is a javascript function I wrote but it's not working
function countPage(){
var clPg1 = 160; //character limit for page 1
var clPg2 = 146; //character limit for page 2
var clOtherPg = 153; //character limit for other pages

Hello everyone... I've got a question about an onKeyUp event. I'm using a text box that HAS to be a negative number therefore it has to have a - sign in front of the number. Can someone point me in the right direction as to how to write a function to do this? Thanks so much...

ah, i've just looked into the operators in more details and -= is just for numbers... so this won't work. i presume this is going to be the wrong method then.
I have a form that collects information about up to 5 items. I would
like the user to be able to select from a drop down menu how many items
for which they want to compare information, and then have the form
change the number of input fields accordingly.
In other words, if the user selects enter info for 3 items, then input
fields for only 3 items are shown, if they change it to 4 items, then a
fourth column shows up in the table with the appropriate input fields.
How do you take a long number such as Math.PI and break it out into an array? code...
I suppose that because of the decimal you would have to convert it into a string first? It would be ideal if I could keep the number as a number without converting it to a string, but I'm not sure if that's possible.
Every thread I've found online so far seems to indicate that you need a delimiter between the string you want to split up - that you can't just put every character of a string into an array... but there must be a way.
In http:www.dreaminco...wtopic51264.htm a code was proposed for generating a random number within an array and then printing it into the html document using document.write.Is it possible to go one step ahead and feeding the result into an html href function?
