JavaScript - Prob Checking For 10 Digits
Hello all
I'm trying to get this function to check for 10 digits only but alert shows regardless of less / more or exactly 10 digits --- what am I missing? any help on sorting this greatly appreciated. Code: function validate(form) {
if (document.forms[0].callme.checked) {
var phone = document.forms[0].mobile.value; // assign value to var
phone = phone.replace( /[^\d]/g, "" ); // zap all non-digit characters
if ( document.forms[0].mobile.length != 10 ) // chk for 10 digits{
alert("Enter 10 numbers");
return false;
} else {
alert("Yahoo");
}
}
low tech Similar TutorialsOoook so this is probably the stupidest question ever. I know in java you can take advantage of a number being an int (not double) and divide by something without getting a remainder. But in javascript you dont declare what kind of variable something is. So my problem is: Given any double or triple digit number, how do i get all but the last digit. Like if i have 13, I need to make an int with 1. If it's 103 i need one with 10. Thanks!! Is it possible to convert the getTime() result into an actual number or text type format where the length function can be used to return only the last 2 digits of the number in a text or number format that is NOT a date format? I have spent quite a bit of time hunting for this and suspect that I am attempting the impossible ?? Thanx Disregard - I believe I have figured it out finally!! hi, i'm trying to keep a copy of a variable at 4 digits.. this is what i came up with.. it's working but i'm only a noob, so i would very like to know is there any other simpler and/or elegant way to do this.. also i would appreciate it if you could point out any bad syntax or something.. Code:
page = 100
function makeit4digits(){
page4digit = page
if (page<10)
{
page4digit = "000"+ page
}
else if (page<100)
{
page4digit = "00"+ page
}
else if (page<1000)
{
page4digit = "0"+ page
}
}
I have a number var number = 1,235.326232 I need to display it like following with the last 4 numbers in red. 1,235.32 6232 I have tried number.slice(0,-4)+"<font color='red'>"+number.substr(number.length-5,4); however it keeps messing up the comma and decimal placement. Hello, I am a hobbyist coder making a basic website for a friend, and I have a small problem. On an image slideshow, there is a counter at the bottom showing what image it is up to (ie 7/15), I'm not entirely sure how to change this into double digits (ie 07/15) I've found this thread (http://www.codingforums.com/showthread.php?t=212321) but am unsure how to integrate it into the slideshow I'm using, which is a different one. Here is the part from my JS I think that needs modifying: Code:
if (setting.displaymode.type=="manual" &&
!setting.displaymode.wraparound){
this.paginatecontrol()
}
if (setting.$status) //if status container defined
setting.$status.html(setting.curimage+1 + " / " + totalimages)
Is this the right bit of code? If more of the code is needed to solve this please let me know. Any help is greatly appreciated! I have the following string "d3-23-76-546" I'm looking for a regular expression that will match everything in this string before 546 so that I can replace it with an empty string and just be left with 546. The string could be of any length and contain any number of hyphens. Hello, I've obtained the following code. Code: function makeDate(){
var d = new Date();
var strDate=d.getFullYear() + "/" + (d.getMonth()+1) + "/" + d.getDate() + " ";
strDate += d.getHours() + ":" + d.getMinutes() +":"+ d.getSeconds() ;
return strDate;
and I think I'm going to get the time and date indications in 2 digits. I want to get it like this: 2009/12/07 18:07:33 NOT like: 2009/12/7 18:7:33 How should I alter the code? Can anyone help? Thanks in advance. Hi I would like to write a parser like the one below except I would like it to take characters with the the digits like 345j, 982p0, what would I change to be able to have characters with numbers? Code: ts.addParser({
id: "digit",
is: function (s, table) {
var c = table.config;
return $.tablesorter.isDigit(s, c);
}, format: function (s) {
return $.tablesorter.formatFloat(s);
}, type: "numeric"
});
I am working on my personal portfolio site, and am using a code that will make each portfolio piece appear in a new div when the name of the piece is clicked on. The problem is, JS does not seem to recognize double digits. I am not familiar with JS at all, I just got comfortable with CSS/HTML a few weeks ago! I am in over my head. It would really, really help if someone could show me how to change the code so that I could make about 15 to 20 divs instead of 9. Here is the code: Code: <script language="JavaScript">
numdivs=9
IE5=NN4=NN6=false
if(document.all)IE5=true
else if(document.layers)NN4=true
else if(document.getElementById)NN6=true
function init() {
showDiv(0)
}
function showDiv( which ) {
for(i=0;i<numdivs;i++) {
if(NN4) eval("document.div"+i+".visibility='hidden'")
if(IE5) eval("document.all.div"+i+".style.visibility='hidden'")
if(NN6) eval("document.getElementById('div"+i+"').style.visibility='hidden'")
}
if(NN4) eval("document.div"+which+".visibility='visible'")
if(IE5) eval("document.all.div"+which+".style.visibility='visible'")
if(NN6) eval("document.getElementById('div"+which+"').style.visibility='visible'")
}

Thank you for taking the time to read this! Hopefully someone can help. I am using a great js gallery script from ....http://coffeescripter.com/code/ad-gallery/ they have a counter for the number of images shown, the number changes as user clicks on next bottom. from looking at the script, the counter is anchor to .ad-info and the counter code from the JS is ..... _afterShow: function() { this.gallery_info.html((this.current_index + 1) + ' / '+ this.images.length); if(!this.settings.cycle) { Can anyone help make the number show double digits only for the numbers 1,2,3,4,5,6,7,8,9 (example- 03/07 or 09/28 or 03/58).. etc..etc thanks for looking. If number is more than 24 digits, modulus operator is not giving correct output here attached sample code [code]<script type="text/javascript"> var a=10000000000000000000000.0; var b=10.0; var c=a % b; alert("c"+c); </script>[code] please tel me solution So far I've logged forty hours in total trying to locate and fix the major problems in this code. I've worked with two other forums and a pay-by-minute guru to no avail. I am hopeful that the good folks here at CodingForums will be able to take this code the final distance. I'll try to be verbose without boring anyone. Summary: This code was written in 2005/2007 by "Wonder" at ProBoards. I teach a fourth grade game design and applied mathematics class to home-schoolers on a ProBoards forum. It is placed in the global footer of the forum to allow forum members to roll dice in their posts. The code was incomplete. I worked with "Jordan" at ProBoards to fix the parts that were incomplete. A problem with the code resulted. Primary resolution I'm seeking: Right now the code does everything I could possibly want. However, it is mistakenly reading double-digit numbers (XY) as X = sides of die and Y = a negative modifier. Once this issue is fixed, I can take the roller back to my students and they can game together. Secondary resolutions I'm seeking: (1) I've been told twice that the code should be "tabbed out." Not sure what that means but I guess it makes it less messy. (2) When clicking the "Add Tag" button the code generates, it automatically inserts [dice=6] into a forum post. Would love this to simply be [dice=X] The original code from "Wonder": Code: <style type="text/css">
.dicebg {background-color: FFFFFF;border:solid 2px #000000;}
.dicefont {background-color: FFFFFF;color: 000000; font-weight:bold;}
</style>

My incredibly detailed account of my last few weeks with this code: Back in 2005, a user named "Wonder" wrote a nifty piece of code that fits into any ole ProBoard's global footer. Once installed on a forum, it allows users to type the command [dice=X] where X is the number of sides for the single die they want to roll and it gives them a random result that's very attractive (a small white box with a black border and a bold, large result with smaller text below that reads: Xsides) and not "easy" to change/alter/cheat. To roll more than one die, you simply string the command like [dice=X][dice=X][dice=X][dice=X]. The code also allows for positive modifiers (bonuses) such as [dice=X+Y] where the result has the same compact, attractive format and the small text reads: Xsides+Y Wonder posted that his code would also allow negative modifiers (penalties) but, actually, no one seems to have ever tested that part... until September 2009 when along came pesky me. I went over to the ProBoards support forum because Wonder's code is included in their official database. I posted the problem and a user named Jordan tweaked the code several times, each time getting it closer to providing the correct result. The correct result being that when a user types the command [dice=X-Y] the result is the attractive box, the larger number above and the smaller text below that reads Xsides-Y (in addition to continuing to accept [dice=X] and [dice=X+Y] and offer the same format of results). Jordan's version of the code now does all this. But when I started testing it I realized that whenever a user types a command that gives the die double-digit sides (10, 12, 20, etc), the code now reads it like this: [dice=10] results in 1sides-0 or [dice=12] results in 1sides-2. So double-digit numbers are being read as the number of sides and a negative modifier *sigh* Very bad news. Jordan needed to pass on further work on the code because (understandably) it was taking too much time and it was "messy." Since I am not a coder myself, most JavaScript looks messy to me but I believe Jordan. I then took the code to a pay-by-minute help website but was gently told that the code was so messy that it would take too long to debug and it wouldn't be worth the charge since the roller is being used for a non-profit classroom project for my fourth graders. I thought that was very thoughtful... but I'm back at square one, really. I have attached everything I have: The very original code from Wonder (the one that doesn't read negative modifiers at all) and the latest from Jordan (that reads double-digits incorrectly). The only other cute/attractive thing about the code that I'll point out (so you don't see it in the code and wonder, "What the heck is that?" is: When you install the code into a forum, it adds a tiny die-shaped button to the Add Tags menu. Users can click the little thing and the code automatically inserts [dice=6] for them. Personally, this doesn't help my students and I would love it if the button just inserted [dice=X] but that's fine. *deep breath* Whew! That's about it. Thank you for putting up with my blather. I sincerely appreciate any help you can offer. I know your time is valuable and I've taken quite a bit just posting my full report... I just wanted to try to be verbose :) Jennifer i am desperate to know what is wrong with this script Mermaid Holidays offers discounts for children of families who have booked holidays.

Thanks Shelby I need to check to see if a cookie has been previously created: Code: var startnum = readCookie('a1');
if (document.cookie.indexOf('a1') == -1){
var startnum = "0";
}
Should line 2 be: Code: if (document.cookie.indexOf('a1') == null){
? Does == -1 do the same thing? hello, This seems very basic, but I am running into a complication. What I would like to do is check if a certain div is displayed or hidden (really doesnt matter which) then set a map zoom level based upon that. here is my current function. function closeDirections(){ gdir.clear(); if(document.getElementById("river").style.display="none"){ map.setZoom(16); hideID('river'); showID('main'); } if(document.getElementById("main").style.display="none"){ map.setZoom(12); hideID('main'); showID('river'); } } Also here is a link to my map, just in case. map I have tried several variations, but from what I can tell with every instance, it only examines the first and never considers the second "if". I thought to rememdy this issue by using if/else...same issue. The only thing I could think is a nested if statements, but I am not sure what to use as a parent if. I have searched for a while, but cannot seem to find something like an .is_hidden(). Something that I could see if its true/false. Any help would be very much appreciated. I keep getting myself into trouble because I tend to use my Java reference when coding Javascript, and of course Javascript doesn't support all Java functions. I've just discovered that apparently Javascript doesn't support the trim() function. But curiously, if I code it as: mystring.trim() then Firefox will handle it without any errors. (I haven't actually checked to see if whitespace is removed from around the string.) But when I code it like this: trim(mystring) then firefox gives an error. I've also found a couple of situations where I've made syntax errors, and Firefox gives no error message. This makes debugging tricky, since the only resource I have available is Firefox's Error Console. Safari has no error reporting whatsoever, AFAIK. MSIE seems to find some errors that Firefox misses, but I don't have MSIE on my main computer, so it's a nuisance to use. As a hobbyist, I have no budget to buy Javascript development tools. Is there something free available that does a better job of finding errors? Hey Guys, I am a student doing my Cert IV in IT and am having a bit of trouble with some code. I have a form that when a letter is entered it returns a message saying you need to enter numbers in, and am trying to find a way of it checking if there are spaces in the numbers entered at the same time as checking if a number has been entered. My code looks as follows: Code:
<html>
<head>
<title>Activity 2.25</title>
</head>
<script type="text/javascript">
function validateform()
{
var element;
var BikeMoney;
var TVMoney;
var iPodMoney;
var CarPrice;
var flag;
flag="OK"
element=document.getElementsByTagName('input');
for(counter=0; counter<element.length; counter++)
{
switch (element[counter].type)
{
case "submit":
break;
default:
if(isNaN(element[counter].value))
{
alert("You will need to enter a number into " + element[counter].name);
flag="NotOK"
}
else
{
BikeMoney=element[0].value;
TVMoney=element[1].value;
iPodMoney=element[2].value;
CarPrice=element[3].value;
}
}
}
if(flag=="OK")
if ((Number(BikeMoney)) && (Number(TVMoney)) && (Number(iPodMoney)) && (Number(CarPrice)))
{
TotalMoney = parseFloat (BikeMoney) + parseFloat (TVMoney) + parseFloat (iPodMoney)
if(TotalMoney >= CarPrice)
{
alert("The total money is " + TotalMoney + " and the car price is " + CarPrice + " and you can afford the car");
}
else
{
alert("The total money is " + TotalMoney + " and the car price is " + CarPrice + " and you cannot afford the car");
}
}
else
{
alert("Enter numbers Please");
}
}
</script>
<body>
<form name="input form" method="post" action="">
<table>
<tr><td>Enter money from bike sale</td><td><input type="text" name="Bike Money"></td></tr>
<tr><td>Enter money from TV sale</td><td><input type="text" name="TV Money"></td></tr>
<tr><td>Enter money from iPod sale</td><td><input type="text" name="iPod Money"></td></tr>
