I 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 have a text box which only accepts a numeric value not decimals.and it should not accept a null value.I wrote isnumeric validation for text box.but it is not working?
View 2 Replies View RelatedI 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.

Which just allow me to type numeric data in a text field. I also need sperate script which allow to just type characters in field.
View 2 Replies View RelatedI'm having a problem with this script I'm working on. What I want to do is check that a user has entered only numeric characters in a text box. If not, an error message should be displayed telling the user that this field requires only numeric input.
It seems to be hitting that part of the function, but I'm not sure what I'm doing wrong that the form is still posting back. Here is the code:
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.

But apparently you cannot start an id with a numeric value, and I would like the page to validate. (I have since fixed the other validation errors, but I'm stuck with this one problem.) Is there someway to modify the javascript so that I can use letters instead of numbers?
I'm trying to do something that would be very easy to do in php, but is quite hard in javascrpit due to the lack of support of associative array.

.push() to add clickedElementId as a value associated to a numeric key, but then the re-click is beyond my skills. How would you approach such a typical algo in javascript?
I'm currently using formchek.js to validate various form fields, however, I cannot figure out how to validate a field with a numeric range of 6-10 digits. I apologize in advance for asking such a question since I'm using formchek.js, but my strength is server-side programming not JavaScript.

View 1 Replies View RelatedI'm trying to wrap up my program now but cannot get it to stop at the right time. It should stop and print the report after the user enters "end" after being prompted to enter a course. I have do{}while loops in place. I also cannot seem to get it to store the amount of credits as totalCredits and the amount of points as totalPoints, which are necessary for the GPA formulaThe inputted Courses, Credits and Grade print out correctly but after typing "end" (in which it doesn't actually end but continues until you input the credit and grade for course "end" (which isn't a course)) it prints the Total Credits and Total "Quality Points" but the wrong GPA..The coding is almost the same as his, but I've tinkered with it for about 8hours straight now. I should've posted this 5hours ago when I first had the thought to do so, but I didn't

Does anyone have a code snippet to compare those values so I can sort
the array of alpha-numeric values that include both characters and
integers in it?
I.e., if we have values like 4236 and 123234, I want 4236 to be second
because 4 is bigger than 1 rather than using the numeric comparison.
The strings can include character values and strings. Basically, I have
the bubble sort function, the question is how to compare those types of
strings in the alpha-numeric order.
i.e.,
A83745
B34974
127734
34456
788
I looked all over the web thinking that this simple question would be
answered somewhere, but could not find the answer.
How 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?
