View 2 RepliesI am modifying a java script that has a function to validate a numeric value. I am attempting to update this function to validate numeric ranges for example =>0 to 35000.
Drawing a blank here on how to do this.. Any help would be greatly apprecaited. I have included the function that I am changing.. Code:
It has appeared that ancient sources give a method for Numeric Date
Validation that involves numerous tests to determine month length;
versions are often posted by incomers here. That sort of code seems
unnecessarily long.
For some while, the following approach has been given here :-
function ValidDate(y, m, d) { // m = 0..11 ; y m d integers, y!=0
with (new Date(y, m, d))
return (getMonth()==m && getDate()==d) }
and it may remain the shortest code. But it does require, in every
case, the creation and disposal of a Date Object.
The following is about 50% longer in code, but about four times faster
in my system - and it seems to be right, too.
function DateOK(Y, M, D) {
return D>0 && (D<=[,31,28,31,30,31,30,31,31,30,31,30,31][M] ||
D==29 && M==2 && Y%4==0 && (Y%100>0 || Y%400==0) ) }
Note that checking for 1 <= M <= 12 is inherent, and that the Leapness
of the year is only determined if the date given is February 29th.
Also, it is easy to use only the quadrennial rule if it is certain that
dates are in 1901-2099, or only two rules for 2001-2399.
I am using Javascript to valid the textbox value..That text box should only allow numerics. So I have used IsNan function to validate the text box value. But it's not working..it is accepting chars/special chars too.
So i need to validate a textbox for negative values and chars,symbols. can any one give some idea about this..
Other than IsNan function is there anything to validate numeric value..
I am trying to add numeric validation to a field that I generate once a button is clicked. The code is:
function addFormField()
{
var id = document.getElementById("id").value;
$("#appendTable").append(
"<div>"+
"<table width='820' border='0' cellspacing='0' cellpadding='5' align='left' style='margin-top:10px;margin-bottom:10px;margin-left:-2px;clear:both;'>"+

I'm struggling to get what I want to work..I have two textfields (using jquery to ensure digits only, limit 3) one is total_available one is currently_available
obviously you cannot have more things available than you have in total, so i need to compare them, and warn when the second one is larger than the first. I tried to modify the jquery validation equalTo with no luck.
i actualy dont care it its not, if i can get the values from the fields, convert them to INT, then compare, and change the innerHTML of a warning DIV that is next to the fields to say "check again" then it will be sorted.

Any examples to restrict entering any value other then numbers in the text box.If any other key other then ther numbers is pressed the function shall not allow any thing other then the numbers to be entered.
View 1 Replies View RelatedI would like to fill a text field using both text and variables..i.e. it would say x+2, so i would write.. (if 2 were a given variable)form.form1.value = "x+" 2(I know that isn't correct, I'm just wondering how I would go about this..)
View 2 Replies View RelatedHow would I go about validating multiple textfields within the same
form to ensure they start with either 1 or 2 numerical digits (from 8
to 14) followed by 2 or 3 text characters eg. 8MN and 14ABC being
acceptable?
I'm trying to add a text box to a form that has some other complications. My "mcomment" in the code below does work but will only accept numbers, and the whole idea was text.
Code:
function n_od(type) {
var f = document.forms.create_account;
$("#id_od").html("<img src='images/nr_loading1.gif' border=0>");
subcat3 = escape($("#subcat3").val());
if (type == 2)
$("#id_od").load("n_autos.php?step=115&w="+f.width.value+
"&fractionw="+$("#fractionw").val()+"&length_in="+f.length_in.value+
"&fractionl="+$("#fractionl").val()+"&mcomment="+f.mcomment.value+
"&mcat="+$("#mcat").val()+"&subcat="+$("#subcat").val()+"&subcat3="+subcat3);
else {
$("#id_od").load("n_autos.php?step=116&w="+f.width.value+"&fractionw="+
$("#fractionw").val()+"&length_in="+f.length_in.value+"&fractionl="+
$("#fractionl").val()+"&mcomment="+f.mcomment.value+"&mcat="+$("#mcat").val());
}
}
I would like to strip out all of the commas in numeric text field called test on blur. New to jQuery. I have had a go at coding would it work? $('input#test').val($('input#test').val().replace(/,/g,'')); and ....... how do i calll it?

View 6 Replies View RelatedI have a text field that I wish to cellect numbers of bird seen. However,
some folk want to use 'c' before the number or '+' after to indicate a fuzzy
number. I have tried creating a function that checks for each of these and
still validates the rest as a number: Code:
i am trying to validate a registeration form containing 10 text fields.there is 10 fields. suppose 6th field is empty/worng.it will show error at div.then if i have a error at field 8, i have to press submit button again. it leads to lot of time taking process.using my code,if i have 4 errors i should click the button 4 times for its validation.it takes lot of time. i need by one click it will show all errors.so help me to validate entire form with one time clicking.

I have these test boxes mentioned below with the array sign I want to check for a validation for these text boxes for an integer value.how can I do it.I know how to do it for the normal one's but how to do for the one's with array[] symbol.
View 3 Replies View RelatedWhat I have right now is when someone hits submit,text appears next to the textarea that says..Please enter an email..That all works fine,but what I would like to do is have the value that I have in the textfield,that has a text style applied from my style sheet(now grey) to turn red,maybe if I made another style inside the CSS file which would be for red text.
Would that be possible? to have one style in the css file,change to another with the javascript?
Here's the validation part of my javascript code
Code:
Is there a way of trimming the value before checking it so that a space for example would still be NULL "".
Code:
if(document.sendmail.emailsubject.value == '')
{
msg += "Subject cannot be left blank.
";
error = true;
}
I'd like to use the jQuery validation plugin as seen on the following example: [URL]
But it doesn't work properly if I use inline/in-filed labels.
i know its for email validation, but how the line 1 works?and also if JQuery has this function?
if (!/^[A-Za-z0-9_.-]+@([A-Za-z0-9-]+.)+[A-Za-z0-9]{2,4}$/.test(
document.forms[0]["email"].value)) {
alert("Please enter a valid e-mail address.");

I have a text area to enter a search, and I have already written the JavaScript part of it (unsure if this is where the problem lies). The text that will go into the text area is a URL. the search button is disabled if there are spaces in the query, or if the field is blank, else the button is enabled. The problem I'm having may or may not be to do with my script. The HTML is set to 'onKeyUp' and 'onBlur' to run the function. now, it works fine, unless the user uses the mouse to copy and paste a URL into the text area. the button remains disabled until the user focuses out of the text area then back in. if ctrl+v is used, then the function works.
View 4 Replies View RelatedI have a phone number field on my form that needs validation, but I'm not sure how to code this. I have the following function to validate a first name is entered and last name. The phone number field must match a 7 digit or 10 digit(with area code)phone number. I want to be able to include paranthese and/or hyphens for the valid phone number.
function checkForm1() {
if (document.forms[0].firstname.value.length == 0) {
alert("You must put in a first name");
[code]....
I use the following code on a form (which works)
function SubmitDocument(){
var frm=document.forms[0];
if(frm.QuestionSeventeen.value=="") {
alert("Please enter your postcode");
window.document.forms[0].QuestionSeventeen.focus();
return false;
}
else
document.forms[0].submit();
}
This is fine, because QuestionSeventeen is a text field. However, I have a number of radio and checkbox values on my form which I need to make sure are not NULL.
I want to make this more efficient and not use LOTS of these nested IFs.
i.e., does anyone have any code that will check firstly specified text fields, then radio buttons, then checkboxes in a more efficient manner?
so.... somthing like this process is what I want to achieve
Function validate()
- make array of text fields, loop through them checking not null THEN
- make array of checkbox fields, loop through them checking not null THEN
- make array of radio button fields, loop through them checking not null THEN
If all OK, save doc otherwise alert that field needs to be filled in then gocus on that field END FUNCTION
The following is a simple form with text boxes..Used java script to check for nulls but how to check my phone number for only integer values ie numbers
View 2 Replies View RelatedI have written a form in HTML which contains username,lastname,email,password and submit.I have written a javascript to validate this form [validate(username,lastname,,password)].On submit this javascript function will be called and hence form get validated. I am passing all the arguements(username,lastname,email and password) to the javascript function..Is it possible to make me a code such that it should call an individual function for each field in the form.for ex:if i have not entered username, last name in the form and attempt to submit, only username arguement should be passed to the function as it comes first in the form.In other sense i want to validate individual text field validation of my form.
