Question

我试图在localstorage中添加一些“联系人”，每次我添加新的联系人我想将其刷新到jquery列表中。如果我不使用localstorage，我会成功地做到这一点。但现在我总是有一些问题，无法解决它。

例如现在我收到此错误

未捕获的TypeError：undefined不是函数

谢谢你的任何想法。

JS：

function showThemAll()
{
    if (!localStorage.contacts) { localStorage.contacts = contact; }
    else
    {
    for (i = 0; i < localStorage.contacts.length; i++) 
    { 
    $("#listC").append(localStorage.contacts[i]);
    $("#listC").listview('refresh');
    }

    }
}

function addContact()
{

    if (!localStorage.contacts) { localStorage.contacts = []; }
   var nameElement = document.getElementById("name");
   var theName = nameElement.value;
   var tellElement = document.getElementById("tell");
   var theTell = tellElement.value;  

   var name = theName;
   var tell = theTell;

   var AreYouHuman = {nam:name , tel:tell}; 

   var liss = "<li><a href='#page2'>"+AreYouHuman.nam+"</a></li>";
   localStorage.contacts.push(AreYouHuman);

    $("#listC").append(liss);
    $("#listC").listview('refresh');


}

function clear()
{
   localStorage.clear();  
}

function showThemAll()
{
  if(localStorage.contacts)
  {
    var contacts=JSON.parse(localStorage.contacts);
    for (i = 0; i < contacts.length; i++) 
   { 
     $("#listC").append(contacts[i]);
     $("#listC").listview('refresh');
   }

   }
 }

function addContact()
{
 var nameElement = document.getElementById("name");
 var theName = nameElement.value;
 var tellElement = document.getElementById("tell");
 var theTell = tellElement.value;  
 var name = theName;
 var tell = theTell;
 var contacts=(localStorage.contacts)? JSON.parse(localStorage.contacts) : [];
 var AreYouHuman = {nam:name , tel:tell}; 

 var liss = "<li><a href='#page2'>"+AreYouHuman.nam+"</a></li>";

 contacts.push(AreYouHuman);
 localStorage.contacts=JSON.stringify(contacts);
$("#listC").append(liss);
$("#listC").listview('refresh');

}

尝试将对象添加到存储阵列中，然后使用循环将其写出
