I have a string that I'd like to replace all characters other than A-Z, a-z and 0-9 with enchar### where ### is the ascii code for the character e.g. 42 = *.
RegExp seems to be the way to go but I'm not sure how to use it to do this.
Any help appreciated.

let me just see if I get what you mean.
this is me(
would become:
thisenchar(ASCII for space)isenchar(ASCII for space)me(ASCII for open bracket)?
You are a *
would become:
You are a enchar042
or even
You are a enchar42
I'm not too bothered about the leading zero.

Blimey that was quick!
Thanks I'll give it go!

was it how you wanted it?
It works absolutely perfectly apart from for some reason it doesn't encode _ (underscore) - any ideas why?
because /w (in the regexp) hold A-Z,a-z,1-9 and _.
You could make another IF function, if it is an underscore, then add the charCode of it there.
Excellent thanks for all your help.

Acidic thanks for all your help again.
My code in full is now:
Which works perfectly.Code:function encode_special_characters(formname) {
var totalElements = window.document.forms[formname].elements.length;
for (elementNumber = 0; elementNumber < totalElements; elementNumber++) {
if (window.document.forms[formname].elements[elementNumber].type == "text" || window.document.forms[formname].elements[elementNumber].type == "textarea") {
inText = window.document.forms[formname].elements[elementNumber].value;
outText = "";
regexp = /\w/gi;
space = " ";
for (i=0; i < inText.length; i++) {
if ((inText.substr(i,1).search(regexp) == 0 || inText.substr(i,1).search(space) == 0) && !inText.substr(i,1).search("_") == 0) {
outText += inText.substr(i,1);
} else {
outText += "enchar" + inText.charCodeAt(i);
}
}
window.document.forms[formname].elements[elementNumber].value = outText;
}
}
}
Thanks again.

no problem
