Javascript zero-padding function set

Source: Internet
Author: User
Sometimes we need to perform the zero-filling operation for less than two digits of the date, or zero-filling for the number of digits. The following functions are very practical. You can select them as needed. You can use the following function to add a certain length to the front or back of the output integer.

function padLeft(str,lenght){ if(str.length >= lenght) return str; else return padLeft("0" +str,lenght); } function padRight(str,lenght){ if(str.length >= lenght) return str; else return padRight(str+"0",lenght); }

Functions that are automatically supplemented before the serial number
Function
Function xx (a, B, c)
{
....
}

Parameters
Xx (98,102, 4)

Result

0098 0099 0100 0101 0102
------------------------------------------------
Do you understand?

Give A starting value (any positive integer smaller than B), an ending value (any positive integer greater than A), and A limited length value (any positive integer ), the function automatically generates a number, and the front side is automatically filled with zero.
The following is the implementation code

《script》 function addZero(a,b,c) {     while(a
 
  ");     } } addZero(1,10,5); 《script》
