javascript - add attribute to input from array; however, using value pair from jsaon -

-

i'm getting error: setattribute' on 'element': 2 arguments required, 1 present.

i want add attributes input i'm avoiding repeats:

//putholder.setattribute("placeholder", "product name (required)"); //putholder.setattribute("ng-model", "vm.product.productname"); //putholder.setattribute("ng-minlength", "4"); //putholder.setattribute("ng-maxlength", "12"); //putholder.removeattribute("size");

i have used following code can't right:

var putholder = document.getelementbyid('customerid'); //var result = '{"placeholder":"product name (required)","ng-model":"vm.product.productname","ng-minlength":"4", "ng-maxlength":"12"}'; //$.each($.parsejson(result), function (k, v) { //        putholder.setattribute(k + ' = ' + v); //    });  //or js  please prefer javascript  json.parse('{"placeholder":"product name (required)","ng-model":"vm.product.productname","ng-minlength":"4", "ng-maxlength":"12"}', function(k, v) {         putholder.setattribute(k + ' = ' + v);     });

i've tried loop 1 elem so:

var names = ["size", "value"]; (var = 0; < names.length; = ++i) {     var cadauno = names[i];     putholder.removeattribute(cadauno); }

i hope can thanks.
