RegExp Help!

[jbaywatch]

I thought the /g was used to specify to keep searching for substrings after the first match?

I need to match all * + and - chars in a string.
(So I can parse the field names out and add them together).

This is my code, that doesn't work.

//this would eventually add the values of form fields 
//Text1 and Text2

var strSum = 'Text1+Text2' 

var oRE = new RegExp('(\+)|(\-)|(\*)|(k)/g');

var arr = oRE.exec(strSum);
alert('arr: ' + arr);

Thanks,

would this
<script>
var strSum = 'Text1+Text2'
strSum=strSum.replace(/[+,-,*]*/g,'')
alert(strSum)
</script>
do yhe trick for you? Victor

Would the String.split method not give you what you want?

var string = "Text1+Text2";
var array = string.split( /[+-]/ );
for( var i = 0; i < array.length; i++ ) {
    alert( &quot;array[&quot; + i + &quot;] is &quot; + array[i] );
}

Oops, make the regexp /[-+*]/

actually i meant (/[\+,\-,\*]*/g (w/o backslash - wasn't replaced) Victor
