Replace function

Copy linkTweet thisAlerts:
Jul 28.2004

Hi,
I need a statement to replace all old_char(s) with the new_char.
Looks like javascript replace() function only raplaces the first one.

st=’ABBACCADD’
st=st.replace(‘A’,’M’);

st=’MBBACCADD’ <– this is the current output.
st=’MBBMCCMDD’ <– This is what i want.

Please advice.

@crh3675Jul 28.2004 — You need to set the "global" paramater:

st=st.replace(/A/g,'M');

or

var regexp="/A/g";

st=st.replace(eval(regexp),'M');

[B]st=st.replace(eval(regexp),'M'); [/B][/QUOTE] For reasons I don't want to go into, do not use that. If you want to define the pattern separately then use:

[font=monospace]<script type="text/javascript">

<!--

st = 'ABBACCADD'

pattern = new RegExp ('A', 'g')

st = st.replace(pattern,'M')

alert(st)

// -->

</script>[/font]

You should almost never use the "eval" function.

@crh3675Jul 29.2004 — Charles, thanks for the info. I was not aware you could pass the parameters as a second argument in a RegExp object. You learn something new everyday ?
