Hello,

Im trying to use the lastIndexOf function to discover where the last “” is located in my string… It seems to have a pb with the \ symbol…  
I tried mystring.lastIndexOf(’""’) and every other possibleway, it always returns -1

Any ideas?

use “\” since it is used in combination with escape characers (like  
and ), it, itself, has to be escaped

Ok i’ve found a way…  
heh = String.fromCharCode(92);  
lastslashpos = myvar.lastIndexOf(heh);  
That seems to work with the ascii code…

Thanks for your reply tho
