今天整理文档, blog一下, 备忘: getNamedItem

getNamedItem以前做xml解析经常用到的函数, 在document dom中也是可用的,
用于获取某个标签的私有属性(非rfc标准的),
这个属性, IE会自动给解析出来, 例如dom.customize_field_name, 就直接可以访问,
Firefox却不会自动给解析,
只能用dom.attributes.getNamedItem('customize_field_name').value访问,

最后通用一点就是都用dom.attributes.getNamedItem('customize_field_name').value, IE下也是支持的

CI Email notification

在cruisecontrol标签之后, project标签之前, 添加plugin, 方便多个project共享htmlemail的通用设置, 例:
<plugin name="htmlemail"
mailhost="mail.mailserver.com"
username="notification@mailserver.com"
password="password"
reportsuccess="always"
returnaddress="notification@mailserver.com"
skipusers="false"
subjectprefix="CI"
defaultsuffix=""
buildresultsurl="http://serveraddress:7777/buildresults/${project.name}"
/>
在project的publishers节点下, 添加htmlemail通知任务:
<onfailure>
<htmlemail>
//只要构建失败, 就发邮件给emp1
<always address="emp1@mailserver.com"/>
// emp2, emp3可以映射到emp2@mailserver.com, emp3@mailserver.com
//此处设置的意思是, 如果本次构建失败了, 则通知提交代码的人 ,
提交代码的人的SCM帐户名称从recently modifications中可以拿到,
然后map就是完成从SCM帐户到email帐户的映射, alias ='emp2'中的emp2就表示SCM的帐户名称.
<map alias="emp2" address="emp2@mailserver.com"/>
<map alias="emp3" address="emp3@mailserver.com"/>
</htmlemail>
</onfailure>

"Object()" or "new Object()" in javascript

We can implement an Object, which can be instance by "Object()" or
"new Object()", here's an example:

function User(name, age){
//if ( !(this instanceof User) )这个也是可以工作的, 但是arguments.callee更通用

if ( !(this instanceof arguments.callee) )
return new User(name, age);

this.name = name + " - " + age;
}

var user = User("xlty", 27); <==> var user = new User("xlty", 27);

flexible arguments

more generic usage of "apply":

Math.min accept a list of number:
> Math.min(1,43);

We want to pass an array to Math.min
> Math.min.apply( Math, array );
