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).
function checkValidFormInput() {
if (document.getElementsByName('customerName').value != '') {
document.getElementById('customerNameImg').innerHTML = '<img alt="Valid" src="images/greenTick.png">';
} else {

I have a web form with several fields. If I copy & paste from a RTF document into a field, the javascript validation and field length are bypassed and cause the form to fail.
View 3 Replies View RelatedI 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?
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?
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:
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
The following Javascript will return an error message if the user did not enter any value into the zip code field. The form will submit even if user entered only 1 character. Does anyone know how to change this to at least minimum 5 characters must be entered into the field?

I have a standard ul list where I need to keep count of the li's within (users can add/remove). This is my function when they remove a list item (.remove is inside the li), it removes the li fine but I always get zero for the rows.

Internet Explorer (in particular IE6) has some limit on maximum URL length. This is very hard to debugging if you don't know what to search for. Maybe jQuery could throw some self-explaining exception when URL is too long?
View 1 Replies View RelatedI'm brand new to jquery, and am trying to set up a dynamic navigation dropdown which is populated with XML by our system (which I can't change.) For some reason, IE6 is showing space where the unused <li></li> tags are. I am trying to create a jquery code which will detect whether or not a link is present in the <li> so I can turn the display off or on dynamically. The relevant jquery code is here:[code]It should eventually appear like this, the way it does in Firefox due to CSS styling:[code]Which means that somehow, it is reading the <a> even when there isn't one.

Code:

View 1 Replies View RelatedI using the jquery_validate.js script to validate my registration page. Does a great job, but I need to increase the length of password characters from 6 to 8, with at least one number. This is the message a user gets:
HTML Code: Please enter at least 6 characters. I'm quite new to jQuery and I looked at the jQuery validation page and couldn't figure out how to change the parameters. It's suppose to be easy to modified by I'm at a loss as to how to change the rule from 6 to 8 and include a number.
delete all option in a dropdown that contain value length of more than zero ie all options that doesnt have value="".
View 1 Replies View RelatedHow would I go about outputting something when a database value is being changed?
e.g. If im typing in a text field, which is saving what ive typed every time i keyup into a database field, it then shows on another page on another user computer as "User is typing something in field X"?
If no typing is happened, i.e. the database field value is not changing, nothing is echoed out.
It would also be cool to have something show "User is deleting text from field X" when the field value is getting shorter.
In pseudo code, something like if the value of database string is bigger than 100ms ago, echo out "user is typing something in", and conversly, if string is getting shorter echo out "user is deleting stuff".
I'm trying to figure out how to make something happen only if there are more than one link inside a div.[code]For now I'm trying to make the little div with the class "cover caption" NOT move when there is only one link in the div.THe reason for this is that I want the whole div to be clickable if there is only one link inside.
View 1 Replies View RelatedI'm trying to get an XML response from a server using:
$('#update-target a').click(function() {
$.ajax({

jQuery.crSpline - Smooth 2D animation along paths of multiple waypoints, using Catmull-Rom splines.
Demo GitHub You provide: A series of (x,y) points that the path should follow. Plugin provides:
Animation along a smooth 2D path that intersects all points. Check out the demo page to see what it looks like.
[Code]...
I just published an early release of this and am looking for feedback from other developers! I made it because I needed an easy way to make animations out of extended sequences of coordinates (without doing the math to stitch together bezier curves), and as far as I could tell no one else had published an easy method to animate along Catmull-Rom splines using jQuery. This is the result, and the hope is that it will be super easy to use and helpful for people besides just me.
Future plans: More general animations and customizable behavior. The current version only animates top and left properties along whole pixel values. It also assumes that every segment of the path should take equal time, resulting in some strange speed changes when moving from small to large segments. Currently brainstorming good fixes for all of these.
i need some creative input. i'm trying to enable the user to input a
length of time, from one day to about 10 years. ideas i've had have
been:
- 3 pull down boxes, for days, months, years
- an entry box for a value and a pull down box for units (days, weeks,
months, years)
- a scroll bar to slide along to a corresponding time
I'm not sure i should even use javascript, maybe an applet instead. I'd
really appreciated some new ideas or brainstorming.
