string methods and pre-defined functions 2

[theEclipse]

There are many string methods, and I would like to know how some of them work. for example<br><br>string.indexOf(something)<br><br>I understand this, but this is where i get confused:<br><br>string.indexOf(something,somethingelse)<br><br>also, are there other string methods that have more than one use?<br><br>thanks <p>theEclipse<br><a href=mailto:eclipse_web@hotmail.com>eclipse_web@hotmail.com</a><br><a href=robacarp.webjump.com>robacarp.webjump.com</a><br>**-Trying to build a documentation of a Javascript DOM, crossbrowser, of course. E-mail me if you know of any little known events and/or methods, etc.

they have several tutorials on Regular Expressions. These are scary, usually unnecessary but very powerful things to understand. If you need functions to work with strings, use them.<br><br>Of course there is also the replace funtion which works with regexps and normal strings like so:<br>str = str.replace(&quot;achar&quot;,&quot;withanotherchar&quot (if i recall, if that doesn't work lemme know and ill post the correct code)<br><br><A HREF="mailto:jared@aauser.com">jared@aauser.com</A>

Dear jaredn,<br><br>&gt; str = str.replace(&quot;achar&quot;,&quot;withanotherchar&quot <br><br>I don't believe that will work for you. The String.replace() method requries a regualar expression as the first argument.<br><br>&gt; These are scary<br><br>Not so scary, more like 'another language'. The real problem is that there is no standard so when you jump from one implementation to another there are some if not many differences.<br><br>&quot;But, that's just my opinion... I could be wrong&quot;.<br>-pete

substring() also has more than one use...<br><br>myString = &quot;abcdef&quot;;<br>yourString = myString.substring(2);<br><br>yourString is equal to &quot;cdef&quot; (I think). Basically, from the number you supply (starting at 0) until the end of the string.<br><br>yourString = myString.substring(2, 4);<br><br>yourString in this case is equal to &quot;cde&quot;... does that make sense?<br><br>lastIndexOf() works the same way as indexOf(), except (of course) in the opposite order. <p>Liam Morley<br><a href=mailto:lmorley@wpi.edu>lmorley@wpi.edu</a><br><a href=
