a text area box that must not have more the 910 characters entered and
they must not be spread over more than 23 lines. I could check the
total length but the problem is people could enter 1 character per
line so you would end up with 910 lines.
Is it possible to make a textarea required only if a certain value is selected from a <select>?
I am trying to make a textarea named ObjOther required only if the value OT is selected from a drop down list named Dmost. Is this possible to do client side using javascript or do I need to look into trying this in another language?

I'm using the validation plugin [url]
I must be missing something, is there not an easy way to validate inline?
For example, I have a required text input that is given focus on page load, I would like for it to throw an error if the user moves to the next field w/o entering any data.
Right now, it only checks for errors on 'submit'.
im loading data via json dynamical from the server. Now i try to optimate the speed of my application and so i want to disable the validate of the fields during the data loading from the server.Is there a simple solution to this? like validate = false

Have a second form (Form2) to the user update the data registered in form1, and the fields user, email, password is already populated with data from the database, the email field I use the remote validation, and as the field already has been completed and read always says that this email already exists, how do I create a rule or method so that when the field is already filled it not do so validating and validate if it is filled with a new email. Email2 have a hidden field in order to do a test type.
How can i validate x inputs with name array like init_date[] with this plugin [URL]
$('#form').validate({
rules: {
year:{required:true,number:true},

I'm working under certain constraints wherein,at a certain point outside my direct control,validate is called with no arguments, but after that I want to set a custom validation function on a form field. I figure there's got to be a way to manipulate validate's internal data structure to add the function, but I don't have a clue as to how.
View 1 Replies View RelatedI have a section of a form containing elements that are not visible, currently just in a hidden div. Some of these elements have validation on them so when the form is submitted it fails on this validation.What I am after is a way to stop the validation firing for any hidden elements. I have tried setting them to 'display: none' and 'visibility: hidden' but this does not have any affect.

I am able to validate the first two textboxes, after that I am not able to validate the remaining fields.
I have an MVC application and I am trying to do some validation but the Validate doesn't seem to fire. I can get it working in a basic html page but for some reason it is not working in my aspx page and I am not sure why. I have all the js files included that I need and the CSS classes defined exactly as they are in the basic example in the jQuery documentation. Here is my code:

I need to validate three textboxes and it will validate for numbers. How should I change my code to validate three textboxes?
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" >

I need to use Javascript to validate 3 textboxes, whereby the users can only key in numbers (because they are phone numbers related fields). If any of the textbox is empty, display an alert message to show which textbox is empty. I do not want to show many alert messages to show that, for example, text1 and text2 are empty, it will show two alert messages. I would need to show one "summarized" alert message instead.
I've been trying to fix this.

I've noticed that IE apparently has a horrible implementation of the
array object, since traversing one with as few as 1000 items it tends
to pop up a dialog informing the user that the script is taking too
long. I tried splitting the array into a 10x100 two-dimensional array
as well as changing the array to a linked list, but neither improved
the code's efficiency sufficiently. Can anyone suggest methods for
optimizing array efficiency, or some other workaround for yet another
one of Bill Gates' blunders?
I have a web document created by a script and instead of going back to
the db I choose to either create an array to iterate through or xml to
parse through.
So, my question is: What are the trade offs between using an array to
load data from or an xml structure?
My array would look like:
myarray = [[],[],[],[]]
My xml like:
<xml>
<data>
<a></a><b></b>
</data>
</xml>
I would use js to iterate or getElementByTagName to find data. I am thinking the page would load faster using xml, and then the user may not even use that functionality. In all cases I have to load the array to memory.
I am with XHTML and CSS as much do I have to learn in JavaScript programming. I’m just beginning to understand and modify the DOM and I ran into something that I couldn’t find a solution for after some extensive search. I have this function:
if(document.getElementById && document.createElement) {
function addflags() {
var children = document.getElementById('pagelist').childNodes;
for(var i = 0; i < children.length; i++) {
children[0].className = 'bulgaria'
children[1].className = 'england'
children[2].className = 'italy'
children[3].className = 'sweden'
}
}
window.
}
The XHTML is an unordered list with 4 list items and sub lists in those list items (plus links in each li) and I want to add a country flag (set as background image in the CSS) to the direct children of the ul (the first level list items).
Now I discovered that Firefox is only reacting to odd array numbers, i.e. children[1], 3, 5, and 7 (the even numbers have "no properties") while IE is applying the classes correctly(?) as intended above (0,1,2,3).
At which point did I go wrong? Sorry if this is a real stupid question but I’m pretty new in this field and my researches didn’t bring any acceptable results.
Is what I'm doing the right approach to creating an array of arrays? I have an external datafile with several employees' records. They are stored in an array with each element of the array being the complete employee record, ie: name, date of hire, etc., etc. These attributes are delimited by a :. I'm trying to separate these attributes while keeping the original array intact. That way I can access these attributes and validate whether or not an instance of the employee object will occur. There are too many records to create this from the start, so I'm trying to implement a for loop to do it for me. This is what I tried: datafile is the name of the original array of employees. emp is the array I'm trying to create .
for(var i=0;i<datafile.length;i++){
var emp = datafile[i].split(":");
//document.writeln(emp.length+"<br>");
/document.writeln(datafile[i]+"<br>");
}
//document.writeln(datafile[0]+"<br>");
How do I set this to "disabled":
<select name="awards[]" multiple size="6">
<option value="1">Award 1</option>
<option value="2">Award 2</option>
<option value="3">Award 3</option>
<option value="4">Award 4</option>
</select>
I don't know how many options there will be as they are fed from a DB.
Anybody got any suggestions about using two arrays. First i need to
ask the user their name and if their require a seat between 1and 5 or
between 6 and 10. I need to assign this information in two arrays.
Any suggestions. I have been working on this so far.
<script type="text/javascript">
var theArray = new Array(10);
//var sizeOfArray = parseInt(prompt("How many items will the array
have?", ""));
for(i=0; i<10; i++)
{
theArray[i] = prompt( "Please enter your name");
}
for(i=0; i<theArray.length; i++)
{
document.writeln( "theArray[" + i + " ] = " + theArray[i] + "<br />");
}
</script>
I want to make algorithms that take selections from arrays and put them together in new ways. here is a simple array I set up for notes of a piano keyboard: Code:
View 4 Replies View RelatedSafari and FF seem to allow this:
var wiggy = "ABCD";
ch = wiggy[2]; // ch will contain the character 'C'
however my JS book seems to insist that I do this:
ch = wiggy.charAt(2);
and indeed doesn't appear to mention the first method at all.
Since for my particular purpose I want to treat the string as an array
of single characters, I prefer the first method rather than the second.
Is there any reason not to pursue this approach?
Any neat way to copy a snapshot of one array to another?
A normal assignment results in the second array pointing to the first,
with changes to either array affecting both.
As a trivial example:
var a=new Array();
a[0]="zero";
var b=a;
b[1]="one";
alert("a="+a.join("*")+String.fromCharCode(10)+"b="+b.join("*"));
.... this results in a and b being identical two-element arrays.
Is there any easy way to set array (b) to be a copy of (a) BY VALUE -
ie using the contents of (a) as they were at the moment of assignment,
but leaving the two arrays separate so that subsequent changes to one
array does not affect the other?
