JS日期和时间戳相互转换【原创】

今天遇到一个关于JS的日期和时间戳相互转换的问题，在网上找了许久略有发现，自己写了两个方法，记录一下。

/**
 * 返回给定时间部件的时间戳
 */
function dateToTimestamp(year, month, day, hours, minutes, seconds) {
	var date = new Date();
	year = year.length == 0 ? date.getFullYear() : year;
	month = month.length == 0 ? date.getMonth() + 1 : month + 1;
	day = day.length == 0 ? date.getDate() : day;
	hours = hours.length == 0 ? date.getHours() : hours;
	minutes = minutes.length == 0 ? date.getMinutes() : minutes;
	seconds = seconds.length == 0 ? date.getSeconds() : seconds;
	// console.log('year = ' + year + ' month = ' + month + ' day =' + day + ' hours = ' + hours + ' minutes=' + minutes + ' seconds = ' + seconds );
	return Date.UTC(year, month, day, hours, minutes, seconds) / 1000 - 3600 *  8
}

/**
 * 返回给定时间戳对应的日期格式
 */
function timestampToDate(timestamp, dateDelimiter, timeDelimiter) {
	var date = new Date();
	timestamp = timestamp == undefined ?  date.getTime() : timestamp;
	dateDelimiter = dateDelimiter == undefined ? '-' : dateDelimiter;
	timeDelimiter = timeDelimiter== undefined ?  ':' : timeDelimiter;
	
	var newDate = new Date(parseInt(timestamp) * 1000);
	var year = newDate.getFullYear();
	var month = newDate.getMonth() < 10 ? '0' + newDate.getMonth() : newDate.getMonth();
	var day = newDate.getDate() < 10 ? '0' + newDate.getDate() : newDate.getDate();
	var hours = newDate.getHours() < 10 ? '0' +newDate.getHours() : newDate.getHours();
	var minutes = newDate.getMinutes() < 10 ? '0' + newDate.getMinutes() : newDate.getMinutes();
	var seconds = newDate.getSeconds() < 10 ? '0' + newDate.getSeconds() : newDate.getSeconds();
	var fomateDateTime = year + ''+ dateDelimiter + '' + month + '' + dateDelimiter +''+ day + ' ' + hours + '' +  timeDelimiter + '' + minutes +'' + timeDelimiter + '' + seconds
	// console.log('fomateDateTime = ' +fomateDateTime);
	return fomateDateTime;
}

农历名称转换类【转载】

今天用到一个公历转换成农历的类，在网上找的的，做了一下修改，现在可以使用了。收藏一下，以后可能还会用到。

Ubuntu源码安装LAMP环境【原创】

(1).安装libxml2

cd libxml2-2.7.8/

./configure --prefix=/usr/local/libxml2

make && make install

(2).安装libmcrypt

cd ../libmcrypt-2.5.8/

./configure --prefix=/usr/local/libmcrypt

出错： configure: error: C++ compiler cannot create executables See `config.log' for more details.

解决方法：apt-get install g++

./configure --prefix=/usr/local/libmcrypt

make && make install

(3).安装zlib

cd ../zlib-1.2.5/

./configure --prefix=/usr/local/zlib

make && make install

(4)安装libpng

cd ../libpng-1.5.5/

./configure --prefix=/usr/local/libpng

出错：configure: error: zlib not installed

解决方法：重新安装zlib到系统

cd ../zlib-1.2.5/

./configure

make && make install

cd ../libpng-1.5.5/

./configure --prefix=/usr/local/libpng

make && make install

(5)安装jpeg8

cd ../jpeg-8b/

PHP合成图是处理有透明背景的图片【原创】

今天在合成图是遇到个问题，背景图片有个透明色的背景，而且是圆角的，这个用普通的画布会出现问题，比如白色的画布，背景图的圆角出就会显得很难看（有个白色的角）

Google了一下，找到了一个方法。见代码：

imagealphablending

此函数，开启或关闭一个真彩色图像资源的混色模式。开启与关闭混合模式有什么区别呢？如果不涉及透明度的问题，两个模式没什么区别，但是如果是在一张画布上画一条透明颜色的线，不同的混合模式将出现不同的效果，如果混合模式开启，则透明线的颜色会与原背景中的颜色叠加，计算出新的颜色，显示出来，如果混合模式关闭，则透明线的颜色直接覆盖到画布中对应位置的颜色值。

简单来说，开启混合模式，颜色叠加，关闭混合模式，颜色覆盖。

imagecolorallocatealpha

类似于拾色器的功能，就是生成一个颜色，的行为和 imagecolorallocate 相同，但多了一个额外的透明度参数 alpha，其值从 0 到 127。0 表示完全不透明，127 表示完全透明。

imagesavealpha

设置标记以在保存 PNG 图像时保存完整的 alpha 通道信息，如果你想保存一个透明的png图标，这个函数是必要的。

使用JavaScript的JSONP实现跨域访问【原创】

JSON 是用于在浏览器和服务器之间交换信息的轻量级数据格式（与 XML 相比）。JOSON 依赖于 JavaScript 开发人员，因为它是 JavaScript 对象的字符串表示。JSONP广泛应用于跨站调用json数据的API当中。

一般来说位于 server1.example.com 的网页无法与不是 server1.example.com 的服务器沟通，而 HTML 的 <script> 元素是一个例外。利用 <script> 元素的这个开放策略，网页可以得到从其他来源动态产生的 JSON 资料，而这种使用模式就是所谓的 JSONP。

下面看一个JSONP的简单实例吧。

服务器端的脚本实现（PHP）：http://www.test.com/index.php

<?php
header("Content-Type: text/html; charset=UTF-8");
$student_info = array(
	'name' => 'fisher',
	'sex'=>1,
	'age'=>20
);
echo $_GET['callback'] . '(' . json_encode($student_info) . ');';

客户端脚本实现（javascript ）：file:///C:/Users/fisher/Desktop/index.html

<script type="text/javascript">
function studentInfo(data) {
	alert(data.name);
}
</script>
<script type="text/javascript" src="http://www.test.com/index.php?callback=studentInfo"></script>

下面是利用JQuery实现的JSONP
