function pushtoArray(myarr,mydata){   if(myarr.length==0){     myarr.push(mydata);   }else{     var oktopush=true;     for(var ele in myarr){       if(myarr[ele]==mydata){         oktopush=false;       }     }     if(oktopush){       myarr.push(mydata);     }   }   return myarr; }

Array.prototype.remove = function(val) {     var index = this.indexOf(val);     if (index > -1) {       this.splice(index, 1);     }   };

function setObjectStorage(itemname,myobj){   localStorage.setItem(itemname, JSON.stringify(myobj)); } function getObjectStorage(itemname){   return JSON.parse(localStorage.getItem(itemname)); }
