HTML / Javascript - Trouble changing text when clicked -

-

so have html code here: 

<body> <b style="font-size: 26px;">how game works</b> <u id="howtoplay_hideshow" style="color: #9ff;">[hide]</u><br> </body>

and used javascript turn hide text show, , show hide when clicked on.

<script> var howgameworks_hidden = false; document.getelementbyid("howtoplay_hideshow").onclick = function () {     if (howgameworks_hidden == false) {         document.getelementbyid("howtoplay_hideshow").innerhtml = "[show]";         howgameworks_hidden = true;     }     if (howgameworks_hidden == true) {         document.getelementbyid("howtoplay_hideshow").innerhtml = "[hide]";         howgameworks_hidden = false;     } } </script>

this, however, not seem work. clicking on hide , show text has no effect @ all. tried removing piece of code:

if(howgameworks_hidden == true) {     document.getelementbyid("howtoplay_hideshow").innerhtml = "[hide]";     howgameworks_hidden = false;   }

and correctly turns hide text show when click (but, of course, not turn show text hide).

so how code working?

this because second if statement triggered if first 1 does, since set howgameworks_hidden true in it. need use else:

if(howgameworks_hidden == false) {   document.getelementbyid("howtoplay_hideshow").innerhtml = "[show]";   howgameworks_hidden = true; }  else if(howgameworks_hidden == true) {   document.getelementbyid("howtoplay_hideshow").innerhtml = "[hide]";   howgameworks_hidden = false; }
