index.html的代码

<!DOCTYPE html><html lang="en"><head>
    <meta charset="UTF-8">
    <title>H5表格提交</title>
    <script src="appWeb.js"></script></head><body>
    <p id="msg"></p>

    var data = document.getElementById(id).value;    var time = new Date().getTime();
    localStorage.setItem(time,data);
    loadStorage('msg');
}function loadStorage(id){
    var result = "<table border = '1'>";    for(var i = 0;i < loadStorage.length;i++){        var key = localStorage.key(i);        var value = localStorage.getItem(key);        var date = new Date();
        date.setTime(key);
        result += "<tr><td>"+value+"</td><td>"+date+"</td></tr>";
    }
    result += "</table>";    var target = document.getElementById(id);
    target.innerHTML = result;
}function clearStorage(){
    localStorage.clear();
