Better way to check for characters

[Andyza]

This function checks if a string contains commas or dots. Is there a
simpler, better way to write the function?

function CheckCharacters(x) {
var CharPos = x.indexOf(",")
if (CharPos != -1) {
alert("String contains commas.");
}
CharPos = x.indexOf(".")
if (CharPos != -1) {
alert("string contains dots.");
}
}


I call it using:

<form name="myForm" ... >
....
<input type="text" name="txtBox"
onBlur="CheckCharacters(myForm.txtBox.value)">
....
</form>


Thanks.

Are you trying to let us do your school assignment?

Didn't you read recent postings about RegEx?

'read recent' says it all: all.

I "dropped out" of school many years ago... But thank you for your
concern Evertjan.
