javascript - Uncaught TypeError: Object function has no method 'split' -

no errors in console present, though function not seem adding dashes intended do. also, code creates formatting problems on site meaning wrong this.

code:

    $('#inventory_accountnumber').blur(function(){         var accounts = $(this).val;         var accountsnum = [];         accountnum = accounts.split(",");         for(var i=0;i<accountnum.length;i++) {             var newstr = '';             if(accountnum[i].length == 24) {                 newstr += accountnum[i].substring(0,4) + '-';                 newstr += accountnum[i].substring(4,7) + '-';                 newstr += accountnum[i].substring(7,10) + '-';                 newstr += accountnum[i].substring(10,14) + '-';                 newstr += accountnum[i].substring(14,20) + '-';                 newstr += accountnum[i].substring(20,24) + '-';                 newstr += '0000-000';                 accountnum[i] = newstr;             }             else if(accountnum[i].length == 32) {                 newstr += accountnum[i].substring(0,4) + '-' ;               newstr += accountnum[i].substring(4,7) + '-';                 newstr += accountnum[i].substring(7,10) + '-';                 newstr += accountnum[i].substring(10,14) + '-';                 newstr += accountnum[i].substring(14,20) + '-';                 newstr += accountnum[i].substring(20,24) + '-';                 newstr += '0000-000';                 accountnum[i] = newstr;             }         }         accountnum.join(',');         $(this).val = accountnum;      }); 

jsfiddle

this culprit:

var accounts = $(this).val; 

that should read:

var accounts = $(this).val(); 

what have there function reference, not value of function's return statement.
