I'm trying to keep a copy of a variable at 4 digits. This is what I came up with.
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
}}
From any page, I want to be able to call a JS function that will do the
equivelant of select all, and copy. This data will then be posted to a
page that will log it.
This would be easy using copy/paste functionality but I don't want to
screw-up users copy/paste buffer. Anyone have an example of how to
retrieve all text with similar formatting of copying page to notepad
without using copy/paste functionality?
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.
<script language="JavaScript1.2" type="text/javascript">
function num2words (num) {
num = num.replace(/[^0-9]/, ""); //removes all non-numeric characters.
break3 = new Array ("","Thousand","Million","Billion","Trillion","Quadrillion","Quintillion");
one2twenty = new Array ("","One", "Two", "Three", "Four", "Five", "Six", "Seven", "Eight", "Nine", "Ten", "Eleven", "Twelve", "Thirteen", "Fourteen", "Fifteen", "Sixteen", "Seventeen", "Eighteen", "Nineteen");
tens = new Array("","","Twenty", "Thirty", "Fourty", "Fifty", "Sixty", "Seventy", "Eighty", "Ninety");
num_split = new Array();
for ( x=Math.ceil(num.length/3); x>0; x-- ) {
if ( num.length > 3 ) {
num_split[num_split.length] = num.substring(num.length-3,num.length);
num = num.substring(0, num.length-3);
} else {
num_split[num_split.length] = num;
num = "";
}
}
num_split = num_split.reverse();
ret = "";
for ( x in num_split ) {
suff = num_split.length-x-1;
val = num_split[x];
if ( val < 20) {
val = one2twenty[val];
hun = "";
} else {
if ( val >= 100 ) {
hun = one2twenty[val.charAt(0)]+" Hundred ";
ten = val.charAt(1);
one = val.charAt(2);
} else {
hun = "";
ten = val.charAt(0);
one = val.charAt(1);
}
if ( one == 0 ) {
val = tens[ten]+one2twenty[one];
} else if ( ten >= 2 ) {
val = tens[ten]+"-"+one2twenty[one];
} else {
val = one2twenty[ten.one];
}
}
ret += hun+val+" "+break3[suff];
if ( suff != "" ) ret += ", ";
}
return ret;
}
document.write(num2words("1275h33"));
</script>
I'm trying to check whether a string is all digits. This part is
easy:
function allDigits( str ) {
var foo=str.split( '' ); // better than charAt()?
for( var idx=0; idx < foo.length; idx++ ) {
if( !isDigit(foo[idx]) ) {
return false;
}
}
return true;
}
I'm not sure about how to implement isDigit(). Is this the best way?
function isDigit( s ) {
if( s.length > 1 ) {
return false;
}
var nums=﾿?'
return nums.indexOf(s) != -1;
}
Like, I want to select the last two digits (like €50,25) to make it a bit smaller. I would put it inside a Paragraphs. Is there a selector for this?

I need to remove non digits from a number.
I thought I could do this:
var phone=དྷ-p67s82'
var re=/D/g;
phone=phone.replace(re,'');
alert(phone) yields: 22-p67s82
What dumb thing am I missing. That regex removes nothing.
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.

I have a calendar that I have got working, however I want the calender to have double digits at all times, 01, 02 etc not 1,2 as it is at the moment, i have been playing around with the code but can't figure out which bit effects it.

function buildCal(m, y, cM, cH, cDW, cD, brdr){
var mn=['January','February','March','April','May','June','July','August','September','October','November','December'];
[Code].....
I wrote a regex to edit a decimal number. you're allowed 1,2, or 3
digits before the decimal point, and 0,1,2,or 3digits after the decimal
point. Of course, you can't enter a decimal point without at least a
digit after ("5." is invalid). So here is my regex
pattern=/^d{1,3}(.(?=d))d{0,3}$/
This works fine for every case except an integer. In other words, it
tests false for entering 5, or 567.
I don't see why it tests false for integers. I'm allowing 1-3 digits
before the decimal point, then a decimal point only if the next
character is a digit (the lookahead clause), and then 0-3 digits after
the decimal point.
I've gotten around this problem with other javascript code around
the regex, but I'd just like to know why this "clean" solution doesn't
work.
I am using a great js gallery script from [URL]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);
ifthis.settings.cycle) {
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
As I am new to java scripts, I usually solve thing with trial and error. What I need is a very simple java script for a count down timer, after searching here I found this:
<font style="font-size:72px" color="#FF0000" face="Arial">
<script type = "text/javascript">
var page = "[URL]";
//The page to redirect to function getSeconds() {
startTimer (3); // 36 hours
} .....
I modified some stuff, as I defined the font face and size, the color as well, and I added a var to open a certain page when the time is over (as I said before, all these modifications came right with trial and error). So, is that script good? or are there better scripts that do the same job? Any script that does the same functionality of the script I mentioned but instead of showing digits it shows:
01 minutes 31 seconds
