Reply To: By pass the string parameter

I tried by passing AddFreq(‘2X’,4) inside the above xml but getting syntax error

My guess would be that you’re not escaping your quotes.

<a onclick='AddFreq( \'2X\',4 );' …

Beyond that, I’m not even sure what xml allows/doesn’t as far a javascript goes. I know that, generally speaking, javascript syntax is not compatible with xml and should be served separately from an external script file.
