A matter on replace function

[keremito1985]

The below function replaces first "z" characters with "_" of every word starts with z. (zeal and zebra changes _eal and _ebra)
The question is how can i replace first "p" chars with "*" in addition to the above func?
mean, if someone fills a textbox like ;

zeal pist zebra pear will come to "_eal *ist _ebra *ear"

=======the code=============
function toUpper() {
var pattern = /(\w)(\w*)/;
var a = document.form1.box.value.split(/\s+/g);
for (i = 0 ; i < a.length ; i ++ ) {
var parts = a.match(pattern);
var firstLetter = parts[1].replace(/z/i, "_");
var restOfWord = parts[2].toLowerCase();
a = firstLetter + restOfWord;
}
document.form1.box.value = a.join(' ');
}

[1] You name the function toUpper() but change char to lower case apart from the replacing z seems self-misleading! That's not me to say how to name it.

[2] The function can _much_ simplified and make concise. I add the requested replacement of p on top of the z and you'll the difference.

function toUpper2() {
var a = document.form1.box.value.split(/\s+/g);
for (var i=0;i<a.length;i++) {
a=a.replace(/^([zZ])(\w*)$/,"_$2");
a=a.replace(/^([pP])(\w*)$/,"*$2");
a=a.toLowerCase();
}
document.form1.box.value = a.join(' ');
}

Thanks a million TSUJI, anyway it works really fine, but i tried some other non-asc?? chars like;

thanks again.

You tried... what have you tried?!!! Even the question is not clear. ?,i,I any position or first postion. One version (any position and final outcome can contain "i" in lower case) is this.

var a = document.form1.box.value.split(/\s+/g);
for (var i=0;i<a.length;i++) {
a=a.replace(/^([zZ])(\w*)$/,"_$2");
a=a.replace(/^([pP])(\w*)$/,"*$2");
a=a.replace(/\?/g,"I");
a=a.replace(/i/g,"?");
a=a.toLowerCase();
}
document.form1.box.value = a.join(' ');
}
