Some times you need to add leading zeros to numbers to form a string like '001' instead of '1'. Rather than writing separate functions or block of code to pad one, two or three zeros, I wrote a general javascript function where you can specify how many zeros to pad. I am sharing this simple javascript function here.
function zeroPad(num,count)
function zeroPad(num,count)
{
var numZeropad = num + '';
while(numZeropad.length < count) {numZeropad = "0" + numZeropad;
}
return numZeropad;
}
The parameters are
The parameters are
- num - The number to be zero padded, this can be a string or number.
- count - The total length of the string after it is zero padded, this should be a number.
Example:
var number1 = 5;
var count1 = 3;
var result = zeroPad(number1,count1);
alert(result);
This will return you '005'

hi surjit i have few doubts to ask
im new to vb6.0 with access i have lakh and above record i need to update those lakh record ,i m able to do it but it takes long time can you give me another idea or solution how to do it very simple
Hi Deepak,
I am not that much familiar with Microsoft Access, but I can point you to some topics that may help you. I recomment you to try the first option, since I am not sure about the 2nd one.
1) You have to optmize the database and queries for better speed. The below url gives you more info about how to effectively use Microsoft Access. Check the topic "Query Optimization in Microsoft Access" in that page.
Link 1
2) This MSDN page explains how to use Stored Queries in Microsoft Access Databases with ADOX, but you cannot have the performance and functionalities of SQL Server.(Note: I had'nt tried this) You can google search for Stored Queries for further references.

thanks for ur advice i will check with tht and let u know.
bye.........
Just thought I would say that I found this little script useful so thanks!
Ciao,
My question: is the following good enough for iteration?
...
var xxxzeros="00000";//insert more zeros for very long padding ;)
var count=...;//wanted number length
for (x=...)
document.write(...xxxzeros.substr(0,count-x.toString().length)...)
...
hi Ciao,
This is an example for iteration.
function test()
{
var xxxzeros="00000"; //Put as many zeros
var count=xxxzeros.length;
var x =0;
for (x=count;x>0;x--)
{
document.write(xxxzeros.substr(0,x));
document.write("<br>");
}
}
Calling this function will give you the result
00000
0000
000
00
0
Ciao again, you did it soo easily...Big THX! :)
Thanks for this Sujith.
Helped me out a lot!
cheers,

I use:
function padZeros(Num, Zs)
{
return(("00000000000000000000"+Num).slice(-Zs));
}
This can pad op to 20 zeros, but can easily be changed.
Hi goodenov,
Yes, this is a nice function, thanks for sharing it. The only advantage of my function is that the count can be any number.
Thanx
@goodenov:
I like your function, only thing is when the padding is smaller than the number it cuts if off. zero(12345,3) returns 123 instead of 12345.
A fix for that could be:
var zero = function (a,b) {
return (a.toString().length>b)?a:('00000000000000000000'+a).slice(-b);
}
Thanks! I googled and found this, exactly what I was looking for.
Thanks!
ii=5
---------
ii=("000"+ii).match(/(\d{3})$/)[1];
---------
result:
005
