The solution is to use encodeURIComponent () the function encodes the data to be sent.

Function ajax () {$ val = encodeURIComponent ($ ('# note '). val (); $. ajax ({type: 'post', url: 'xxx. php ', data: 'txt =' + $ val, success: function (data) {$ ("# remove "). empty (); $ ("# main" ).html (data); $ (". chg_area "). hide ();}});};

In this way, the special symbols & + will be passed.
