I am building a data aqusition system using PhoneGap. .I am trying to store my form data temporary on local storage using JSON,Data should be visible after I close and reopen the application (after pressing Get Data button),But after I close it only the lastly entered record is visible
This is my code

localStorage.setItem("highscores",JSON.stringify(highscores));
alert("The data has been stored successfully.");
} else {
alert("Your Browser does not support LocalStorage.");
}
}
function readLocal(){
if (window.localStorage) {
var scores =[];
//Get the highscores object
scores = localStorage.getItem("highscores");
scores = JSON.parse(scores);
for (i=0;i<scores.length;i++){
var text = "homeId :"+scores[i].homeId +"<br>"+
"owner:"+ scores[i].owner+"<br>"+
"address"+scores[i].address +"<br>"+
"gramaND"+scores[i].gramaND +"<br>"+

var tbodyx = document.getElementsByTagName("tbody");
