javascript - for loop does not execute twice -



javascript - for loop does not execute twice -

createmodelview: function (obj,vitalslength,headervalue) { for(i = 0, vitalslen = vitalslength; < vitalslen; i++) { // logic } }

two questions

where should place homecoming statement function. if place within loop work.

when phone call function obj.createmodelview(arguments); why not execute twice or n number of times depending upon vitalslength. it executes once.

some possible issues:

first create sure declare 2 variables before loop

var i=0, vitalslen=0;

and check create sure vitalslength number. can isnan or typeof check.

if (isnan(vitalslength)) alert("vitalslength not number");

one of these may or maybe not causing issue, allow me know.

also... can't remember if it's same in javascript it's in other languages, ++i more efficient utilize i++.

as 2 questions:

it can set after loop, if want one. hopefully above prepare it

javascript
