通过jquery.charfirst.pinyin.js实现点击字母自动定位。实现动态加载通讯录数据。
主要代码如下：
<!DOCTYPE html>
<html lang="en">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<meta charset="UTF-8">

<meta name="apple-mobile-web-app-status-bar-style" content="black">
<meta name="format-detection" content="telephone=no">
