string().replace() usage...

[Randell D.]

Folks,

Can someone help my syntax?

var z=myForm.myInputTag.value.string().replace(" ","-");

I would expect the above to allow z to take the value of an input tag
(called myInputTag) and replace spaces with dashes...

It doesn't change the string - nor do I get errors in the Mozilla
javascript conole...

All help, via the newsgroup (for all to learn) is appreciated, thanks

All form values are already interpretted as "string" data types.
Remove the ".string()" from your statement, and it should work. Note
that this change will only put the updated string into your variable,
not the form, as you currently have the code written.

Make the update, then do an "alert()" on the variable to make sure
everything is cool.

You may be thinking of the Object.toString() method; no such thing as a
..string() method. Also: is 'myForm' simply the name of the form? If so
you'll need to use either document.myForm, or
document.getElementById('myForm') with <form id="myForm"...>.
String.replace works with two string arguments, but it's far more
versatile with a regular expression and a replacement string (or
callback function):

var z = document.myForm.myInputTag.value.replace(/ /g, '-');

If you wanted *one* dash, even for multiple spaces:

var z = document.myForm.myInputTag.value.replace(/ +/g, '-');

Thanks for that - I had used a regexp as I didn't believe it was
required... now it works...

Yeah, I had tried sending the output via alert() and even tried with and
without string. I don't know why but when I replaced my arguements in
replace() with a regular expression (suggested in a follow on post from
yours) it worked...

Thanks though,
