Implementation of PHP sprintf function instance _javascript technique based on JS

This article describes the implementation of PHP based on JS sprintf function. Share to everyone for your reference, specific as follows:

The functions are as follows:

<script type= "Text/javascript" >
function sprintf ()
{
  var arg = arguments,
    str = arg[0] | | ",
    I, N;
  for (i = 1, n = arg.length i < n; i++) {
    str = str.replace (/%s/, arg[i]);
  return str;
}
</script>

The first parameter is a string containing the "%s", and the other parameters are the corresponding variables to replace "%s".

Such as:

<script type= "Text/javascript" >
var str = "Bed before%s bright, suspected to be frost on%s; ",
  var1 =" Ming ",
  var2 =" ground ",
  var3 =" Hope ",
  VAR4 =" think ";
str = sprintf (str, var1, VAR2, Var3, VAR4);
</script>

I hope this article will help you with JavaScript programming.
