Controlling Character Length Of A TextArea Field

Aug 1, 2007

I have a text area in one of my forms that I want to control the character size of. In short, I want to keep the text area to 10,000 characters.

What I Have Found: I have found a number of scripts that will control the character length of the text area, while you are typing.

The Problem: If you cut and paste a document that contains 15,000 characters into the text area that is limited to 10,000 characters, it will still take all of the information (i.e. the 15,000 characters), as opposed to limiting/cutting it off.

Does anyone know of a script that will control the overall character length whether it be inserted via key stroke or is copy and pasted into the text area? Or possibly point me in the right direction?

This.form.elements.length Results In 0

Apr 1, 2006

I am trying to do a simple check-all / un-check-all checkbox system.
All of the solutions I have seen use "this.form.elements.length" or a
variant of this.

My scripts don't work because "this.form.elements.length" always
returns 0. Example:

document.write(this.FormName.elements.length);

displays "0"

Am I missing something obvious here?

Using Option.length With Php Array In Form

Feb 16, 2009

Ok the setup is basically this. The user selects a option in a drop down field, whatever they select through javscript additional records are populated in a second select field. This second select field allows for multiple selections, however I am submitting the form to a php script and I want to capture the multiple selections in the second select field. To do that for php I need to turn the field into an array so I have to add the brackets, [], to the name of the select field.

In php you can name the field like so:

Code:
<select name="fld[]" size="1">

The problem is in the js function when I give it a field name with [] the script doesnt work. Here is the js function:

Code:
function channelform(select_value) {
IntPath = document.channel_form.cid[]
TheOptions = IntPath.options.length

[Code]..

You can see the [] for the cid field name. Whenever I add that to the field name the js script is broken. How do I get it to work so that I can pass an array to php when the form submits?

JQuery :: How To Get Password Length On Form

Sep 6, 2010

How can I get password length on form in jquery? I get the password with this:
var sifra=$("#input:password").val();
But when I want to check if password is entered and length is more than 6 characters, it
doesn't work:

if(! sifra){
$("#sifra_p").show();
$("#sifra_p").html("Niste unijeli šifru!");
greska=1;
}else{
if(sifra.length < 6){
$("#sifra_p").show();
$("#sifra_p").html("Šifra mora imati bar 6 znakova!");
greska=1;
}else{
$("#sifra_p").hide();
}}

What could be a problem and what could be a solution. This kind of check works fine
for normally inputs (check, select etc).

Form Validation Form.length

Oct 5, 2006

I want to loop through all the elements in a form so as to check their values in order to validate the relevant fields, i thought i could get the number of form objects within the form using "formName.length." Then use a loop to go through all the form fields.

It seems formName.length is not working for me ... it's returning "undefined" or "0" values. How could i get the number of form objects within a certain form. Code:

Display Form ID Function - Length Is Null

Jul 25, 2010

For some reason i'm getting the error of "length is null". Which is from this.
function display_form(id) {
//Create some variables
var html = "";
var container = "form_container";
var menu = load_menu(id, false);

//Get id
for ( var i = 0; i < menu.length; i++ ) {
alert(i);
}

http = getHTTPObject();
http.onreadystatechange = function() {
if ( http.readyState == 4 && http.status == 200 ) {
document.getElementById(container).innerHTML = http.responseText;
} else {
document.getElemenyById(container).innerHTML = "Loading...";
}}
http.open( "GET", "includes/forms.php?form=" + id );
http.send();
//Watch input fields
//login_listener();
}/*

Here is the function:
function load_menu(menu, return_d) {
//Availible menus
var data = [];
data [ 'login' ] = [ 'Login', 'Register', 'Recovery' ];
data [ 'settings' ] = [ 'Profile', 'Account', 'something' ];

if (return_d == false) {
return data[ menu ];
} else {
//Menu container ID's
var cons = Array('menuitem1','menuitem2','menuitem3');

for ( var i = 0; i < cons.length; i++ ) {
document.getElementById(cons[i]).innerHTML += data[ menu ] [ i ];
}}}

Extra info:
id = login
menu = login

Form Validation Field Values Not Saved If One Field Is Not Completed/invalid?

Feb 3, 2009

The following form validation script works, currently if one of the five fields are completed, a message appears the remaining field(s) must be completed etc. Although the information the user has inputted in the first field is cleared. How can this information be available, if there is one problem in the form it doesn't make sense that the user must re-input all the information again. I look forward to hearing your response,

function validate_form ( )
{
valid = true;

Only Validating One Field At A Time In A Multi Field Form?

Aug 17, 2010

my javascript code is only validating one field at a time (as in it validates on field then submits the form, instead of going through the entire thing and then returning it as true and submitting it...) I'm not sure what to do to be honest, I've looked up google to no real avail.. my variables are declared in a seperate file to the actual even handlers and I have heaps of comments through out it, so please don't judge lol i'm still learning Quote:

//Event Registrations (Variable Declarations) found in validation_chkr.js
//Validate Entire Form using validate_join()
function validate_join()

JQuery :: Add Fixed Value To Form Input And Send To Separate Form Field

Jun 3, 2011

I've have a function to take the value entered in a form text box, add 50 to it and put the result in another text box.

When I enter 650.5 I get 700.5 exactly how I'd expect. But when I enter -650.5 instead of getting -600.5 I get -650.050 as though it is failing to parse the float due to it being negative. My understanding of parseFloat was that it recognises negative numbers. Is there a nice simple way to get this to work?

Pass User Input From A Form To One Database Field Using Several Form Elements

May 4, 2009

I need to pass user input from a form to one database field. I'm relatively new to JS but the idea I had was to have several form elements and use JS to collect the users input and send all the values through a hidden element. What's happening is the variable names are being sent rather than the values. The code below is only passing to the next page. Limitations: I am editing an intranet site built by a 3rd party so a lot of the files we've been given are encrypted. I cannot change the method to post.

Populate A Form's Field (via Hyperlink) Without Access To The Form's Code?

Mar 3, 2011

I work for a very large company that has zero communications between IT and the employees...so there is very little possibility of having any code changed.I need to use a web based system that submits orders for my department. The problem is i must order by "task number". I could have 20-30 task numbers so to complete the order I need to go to my company's page and fill out 15 form fields and submit for each task code. It is a terrible pain. 14 of the 15 fields are the same for each order... only the task code changes.

Form Validation Styling Form Field Borders Green If Ok And Red If Not?

Sep 24, 2009

I've set up a mock registration form page so I can learn a bit about javascript's form validation. (newbie) I want to try to attempt to style the border of a form field green when the user enters the correct info into the form text field and red on all other fields if the user doesnt enter any info into them. When i test it, enter the right info into the username field, leave the others blank, and hit the submit button it styles the username field green ok but it doesnt make the next fields (password and so on) red. just for testing purposes I've put return false on everything so it displays a message when everythings ok.[code]

Form Field With Same Name As Js Form Property--workaround?

Jul 23, 2005

I'm trying to do some javascript form validation and I've discovered a
rather difficult situation to handle with IE.

Let's say there's a form with three input fields named "name",
"method", or "length". Whenever my javascript tries to access the
form's name or length, and the form happens to have input fields named
"name" and "length", I'm actually accessing the input fields and there
seems to be no way to access those properties of the form.

I have an easy workaround for form.length, so there's no need to give
me a workaround for that one, but there's a bigger issue with fields
like name, method, action, etc.

For example, using document.forms[0].name to get the name of the form
seems to map to document.forms[0].elements["name"] istead of the
actual name of the form. Is there a work around for this? I am
writing some generic form validation code, and I can't expect the
person implementing my form validation code to avoid using "name" and
"length" as names for their form fields.
