灰姑娘专题总结

http://cinderella.1905.com/

前两天加急做了一个专题，后来增改了不少东西，还是略吃力。

================================================ 分割线 ===========================================================

1) 页面内添加如下代码，为学员的信息不包含排名。先追加

<script type="text/javascript">
var SPECIALCONFIG = {
nav_tabname : 'index',
voteids : "321834318,321834321,321834332,321834333,321834338,321833823,321833824,321842611,321842613,321842616,321842617,321842618,321842620,321842624",
infos : {"321834318":{"id":321834318,"title":"\u9732\u897f\u00b7\u5b9d\u901a","url":"http:\/\/www.1905.com\/http:\/\/www.1905.com\/mdb\/star\/2700989\/","thumb":"http:\/\/image11.m1905.cn\/uploadfile\/2014\/1216\/20141216025708535339.jpg"},"321834321":{"id":321834321,"title":"\u4e9a\u5386\u5c71\u5fb7\u62c9\u00b7\u9053\u7075","url":"http:\/\/www.1905.com\/http:\/\/www.1905.com\/mdb\/star\/3042415\/","thumb":"http:\/\/image11.m1905.cn\/uploadfile\/2014\/1216\/20141216030224142148.jpg"},"321834332":{"id":321834332,"title":"\u4f0a\u6069\u00b7\u9ea6\u67ef\u8096\u6069","url":"http:\/\/www.1905.com\/http:\/\/www.1905.com\/mdb\/star\/1470642\/","thumb":"http:\/\/image11.m1905.cn\/uploadfile\/2014\/1216\/20141216031510179309.jpg"},"321834333":{"id":321834333,"title":"\u6734\u96c5\u82f1","url":"http:\/\/www.1905.com\/http:\/\/www.1905.com\/mdb\/star\/3042417\/","thumb":"http:\/\/image11.m1905.cn\/uploadfile\/2014\/1216\/20141216031527780475.jpg"},"321834338":{"id":321834338,"title":"\u5d14\u6b63\u5143","url":"http:\/\/www.1905.com\/http:\/\/www.1905.com\/mdb\/star\/3042418\/","thumb":"http:\/\/image11.m1905.cn\/uploadfile\/2014\/1216\/20141216032521520919.jpg"},"321833823":{"id":321833823,"title":"\u6734\u653f\u739f","url":"http:\/\/www.1905.com\/http:\/\/www.1905.com\/mdb\/star\/3042407\/","thumb":"http:\/\/image11.m1905.cn\/uploadfile\/2014\/1215\/20141215031653221905.jpg"},"321833824":{"id":321833824,"title":"\u91d1\u5ba5\u771f","url":"http:\/\/www.1905.com\/http:\/\/www.1905.com\/mdb\/star\/3042408\/","thumb":"http:\/\/image11.m1905.cn\/uploadfile\/2014\/1215\/20141215032147123433.jpg"},"321842611":{"id":321842611,"title":"\u5f20\u99a8\u5143","url":"http:\/\/www.1905.com\/http:\/\/www.1905.com\/mdb\/star\/3042353\/","thumb":"http:\/\/image11.m1905.cn\/uploadfile\/2014\/1211\/20141211034324770365.jpg"}
}
};
</script>

列表页执行js的时候会提示 SPECIALCONFIG 未定义，此时判断只有页面内有 SPECIALCONFIG 的时候出现了问题。

判断SPECIALCONFIG.length 结果 undefined

当不知道怎么判断的时候 可以typeof(SPECIALCONFIG)看下它是什么类型 输出 "object" ，所以可以通过这点判断

if(typeof(SPECIALCONFIG) == 'object'){

　　执行响应操作；

}

2) js追加上面代码里面的信息到html的时候，需要for in遍历

for(var m in SPECIALCONFIG.infos){

}

3) 获取当前时间的方法

A) new Date().getTime() 返回的是当前时间的毫秒数

B) 拼成201412231542这种格式的

date.getFullYear().toString() + (date.getMonth()+1).toString() + date.getDate().toString() + date.getHours().toString() + date.getMinutes().toString();

date.getFullYear()获取到的是数字 用加号不能直接拼接，只能转化为字符串进行拼接 toString()

4) sort() 方法

var arr = [1,5,3,9];

　 arr.sort(); //[1,3,5,9]

var arr = [10,5,40,25,1000,1].sort(); // 10,5,40,25,1000,1

sort() 不按照数值的大小对数字进行排序，要实现这一点，就必须使用一个排序函数：

<script type="text/javascript">

function sortNumber(a,b)
{
return a - b
}
var arr = new Array(6)
arr[0] = "10"
arr[1] = "5"
arr[2] = "40"
arr[3] = "25"
arr[4] = "1000"
arr[5] = "1"document.write(arr.sort(sortNumber))

</script>

5) http://www.1905.com/api/specialvote/special3203.html 请求接口 数据格式是jsonp

$.ajax({
type: "GET",
url : "http://www.1905.com/api/specialvote/special3203.html?time="+freshTime,
dataType:"jsonp",
jsonpCallback:"successCallback",  //请求接口中的回调函数名称
cache : true,

cache

类型：Boolean

默认值: true，dataType 为 script 和 jsonp 时默认为 false。设置为 false 将不缓存此页面。
