• why doesn't boolean value return correctly localstorage? 3 answers

i'm trying execute javascript function depending on value of localstorage key. seems pretty easy, i'm not getting anywhere. here's have -

        <script>     window.onload = function ()     {         setinterval(function()         {             var 1 = localstorage.getitem('one');             if (one !== true)             {                 var elem = document.getelementbyid("one");                 elem.classname = "hide";             }              else if (one !== false)              {                 var elem = document.getelementbyid("one");                 elem.classname = "show";             }             else {                 var elem = document.getelementbyid("one");                 elem.classname = "show";             }         }, 50);     } </script> 

what supposed check every 50ms key "one" in localstorage. if it's true, execute function defined under if statement. if it's false, execute other function that's defined under else or else if statements.

unfortunately, doesn't matter whether or not there entry in localstorage @ all, executes first function(hiding object). i'm not sure why.

any suggestions appreciated.

thanks.

edit - couldn't find information in other posts, because issue has points brought in comments , answers. if string "true" isn't in localstorage begin with, why function still executing?

anything stored in localstore strictly store string key/value pairs. means storing string: "true" , not boolean value true.
