javascript - JS: Function call over-rides my other 2 function calls? -

-

i trying design menu system upgrading attack skills. example, when click upgrade "strike skill", circle 3 subset skills upgrade to.

upgrade system

the problem running function calls. last function of similar type, seems over-ride first 2 functions, instead of filling 3 circles in numbers, instead overwrites last 2 instead. why , how can fix it?

the problem:

skills("skills", "attack1", "i");    skills("skills", "attack2", "ii");   skills("skills", "attack3", "iii");

javascript code: 

 function upgradebar() {      menu("upgrademenu", "systemmenu");  }    function menu(classid, id) {         var button = dom.el("skill"); // apply div location         var x = document.createelement("div");         x.setattribute("class", classid);         x.setattribute("id", id);         button.appendchild(x);      function skills(classid, id, text){         var circle = dom.el("systemmenu"); // apply div location         var x = document.createelement("div");         x.setattribute("class", classid);         x.setattribute("id", id);         circle.appendchild(x);         dom.settext("attack1", text);         }     skills("skills", "attack1", "i");        skills("skills", "attack2", "ii");       skills("skills", "attack3", "iii");   }

css code:

.upgrademenu {     width: 100px;     height: 100px;     background-color: white;     border: 1px solid black;     border-radius: 50px;     position: relative; }  #attack1 {     width: 50px;     height: 50px;     background-color: white;     border: 1px solid black;     border-radius: 50px;     position: absolute;     top: 0;     left: 0;     margin-left: -10px; }  #attack2 {     width: 50px;     height: 50px;     background-color: white;     border: 1px solid black;     border-radius: 50px;     position: absolute;     top: 0;     right: 0;     margin-right: -10px; } #attack3 {     width: 50px;     height: 50px;     background-color: white;     border: 1px solid black;     border-radius: 50px;     position: absolute;     bottom: 0;     margin-left: 23px;     margin-bottom: -10px; }
