how to parse a string

[Priya Jothi]

Hi all,
can any of you plz suggest me how to parse a string that is passed to a javascript method.

Note that there may be more than one delimiter present anywhere in the string.In the following example i have to strip off all the spl chars(like "$" & "{" and so on) and extract only the alphabets.

Ex :

i/p(string) : "${abcd}${efgh}"

o/p (String[]) : {"abcd","efgh"}


In java this is pretty straight as we have StringTokenizer class there.but javascript is not allowing any such classes.but still how to get the output?.plz suggest me the soln at the earliest.

Regards,
Priya.

JavaScript 1.2 (ECMAScript v3) has String.replace() which takes a regular expression and a replacement string.

In your example you may be better off with String.split("$"), which is a crude string tokenizer (returns an array of Strings).

basic idea

<script>
var theStr = "asdasd875875*&^*&^876s8a76dsadkjhkjh";
//var regEx = /\W/gi; 
var regEx = /[^a-zA-Z]/gi;
var newStr = theStr.replace(regEx,"");
alert(newStr);
</script>

or

<script>
var theStr = "{ASD},{FGH}";
var regEx = /[{}]/gi;
var newStr = theStr.replace(regEx,"");
var arrayStr = newStr.split(",")
alert(arrayStr[0]);
</script>

If u know how to use jsp and hava, better use String.split() and charAt() with isDigit() or isChar() methods.

You cannot use JSP and "hava" in a Javascript method.
