How To Check If Variables Are Integer
Aug 16, 2011I have the following Javascript code to make a simple calculation. It works fine the numbers entered are integer. But if the numbers are 1.5 style I get stupid results or NAN error. I would like to add a check to the script which checks:
1- If the value entered is integer or 1.5 style for all fields. If it is not gives an alert message and stop calculating.
2- If the visitor enters 1,5 instead of 1.5 (In Turkey it is a common usage.) I need script replace the 1,5 with 1.5 and then make the calculation

JQuery :: Validation Plugin: Check If A Field Contains An Integer Not Equal To Zero?
Jun 14, 2010I have already done a number of things with Jörn's validation plugin and I'm excited about its features. But here is my question: how do I validate a field so that it fits the two following conditions: it should be an integer and should not be equal to zero? So, if a user enters "0", it should be error; if he/she enters "12.5", it should be error also; but "-3", "125", "40" are OK.

Feb 18, 2010I need to validate three textboxes and it will validate for numbers. How should I change my code to validate three textboxes?
Code:
Code:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
[code]....
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.Next, check if the textbox matches the pattern (which is to check if it has the skeleton of a phone number). If it is, show an alert message that it is alright. Else, show that it does not match.

Convert Value To Integer.
Sep 25, 2007function calculateGst(exGst) {
//percentage of current gst.
var gst = 10;
var gstAmount = (exGst * (1 / gst));
var gstInc = (exGst + gstAmount)
alert(gstAmount);
alert(gstInc);
}
now, the exGst parameter comes from an document.getElemenetById('txtExGst').value in an onclick event.
the problem is this. if 400 is entered at exGst, the gstAmount spits out 40, as it should, but the gstInc spits out 40040...so its treating it like a string rather than a number...

DOM Element Width Can Be Non-integer?
Jun 14, 2010I have some one page whose div elements are aligned by JavaScript. The JavaScript just check a set of div elements to find the max offsetWidth, then set all div elements' width to be the max offsetWidth. It works perfect in most browsers and locales, but it fails on french-France in Firefox on Mac. In this case, the content of div wraps.
<div id="divFoo">
Heure de début :
</div>
for above HTML, below code report "79".
javascript:alert(document.getElementById('divFoo').offsetWidth);
but below code report "79.1333px".
javascript:alert(window.getComputedStyle(document.getElementById('divFoo'),null).width))
The gap between 79.1333 and 79 makes incorrect width set to inline style.I used to thought that offsetWidth and width should always be integer. Is there any way to make offsetWidth round correctly?
