javascript - match is not a function - Error -

i want test object pattern , output if consolel gives me error saying match not function whereas w3school says javascript function

var templateregex = '/\${([\s\s]*?)\}/g';        var gettextnodesin = function(el) {             return $(el).find("*").addback().contents().filter(function() {                 return this.nodetype == 3 ;             });         };          var textnodes = gettextnodesin('#'+currentid);          console.log(textnodes.length);         for(var i=0; i<textnodes.length; i++) {             console.log(textnodes[i]);             if(textnodes[i].match(templateregex)) {                 console.log(textnodes[i]);             }         } 

help please?

it looks you're trying match regexp against node; match string method, not htmlelement method.

note jquery's contents() method returns text nodes, not strings. want use text() or html() instead (just checking jquery's api ref @ glance, i'm not jquery expert).
