I am passing the following to my extjs grid.
how do i escape if there any quotes inside the varaible.
append rval "'description':'$description',"
append rval "'short_description':'$shortDescription',"
Well you could use regsub to substitute all the single quotes e.g.
The first line will place a backslash in front of every apostrophe in the rval variable. The second line will place a backslash in front of every double quote. You have to escape the apostrophe, the double quote and the backslash itself in the regsub command too, hence the triple backslash in the 2nd last argument to regsub
