requirejs可以像java一样操作文件,并且api也是类似；hibernate缓存+EhCache||osCache+隔离级别;跨数据库：多种SQL或中间件(适配器)如hibernate;
new IExecutable(){实现方法};hibernate大数据：改用jdbc,Session.evict,Session.clear+iternator
while(it.hasNext()){ YouObject object = (YouObject)it.next(); session.evict(youObject); sessionFactory.evice(YouObject.class, youObject.getId()); }

参数在IE中的httpwatch中为在stream中，Firefox则在put中；
虽然刷新时数据丢失，但window本身的属性值或对其属性赋的值不会丢失；
子窗体保存变量，用父窗体或刷新及F5事件或弹出对话框或COOKIE
f5是针对当前url的;有些窗体的值是可以不变的如location;
JS中虽然也有引用传值,如果变量重新赋值或最初值为空(null)的除外,此与java同;
用org.springframework.web.filter.DelegatingFilterProxy可以得到静态资源url;配置时filter name用bean名字，并把自已的filter配成bean;
如果更新后报错找不到元素，可能是由于缓存引起，先清缓存。
更新JAR包后要重新加用户包再刷新项目。
@QueryParam从JSON对象取，@PathParam从URL中取，两者都用于GET;POST无需用注解参数；
treeGrid是tree，不是grid;treeGrid的data不是数据而是tree;initialData是data;getData().getRoot()也是tree;
treeGrid的数据源：1，data;2,tree;
tree的data数据源：rootNode._isOpen_isc_ResultTree_1=true;而在9.0中是isOpen；
project->build project:刷新代码到服务器；也可以在window->preferences->general->workspace中设置；
注入bean时可以和定义名称不同，但如果有两个实现，则需要用name属性指定；
除参数外，未定义时报错而不能得到undefined这个值，应用try-catch(e),或通过定义解决,如：var cc2=cc1||undefined;var aa1=undefined,aa2=aa1&&9,
aa3=aa2&&aa2.bb;bb可以是属性或方法,但不可以var cc1=cc1||undefined;否则cc1即使有值也可能找不到而找到var cc1(undefined)；
而如:var isc=isc,isc_c_Canvas_imgHTML_Temp=isc&&isc.Canvas&&isc.Canvas.imgHTML;是可以的;
?a:b可以改为a||b,a,b都可以是变量或一段脚本；
<a>标签中的href用#则不会跳转，但url会加上href的内容(可用window.location.hash得到)；
访问到旧页面：1，缓存，2，build project;3,刷新
jquery.load的页面中不能用document.write,但可用$("#...").html(...)
请求HTML可以是异步，但HTML内的JS需要同步，除非在正文后的JS,都应基于HTML的执行顺序来加载JS,但js请求已从http改成xhr,但其它如css,img等静态资源及document.write的js例外.
self.each( callback, [ responseText, status, jqXHR ] )//each中定义了each: function(object,callback,args),此处传入一个数组参数
$.fn jquery 所有FN对象，如$.fn.disk ，使用时可以用$("#..").disk来使用；
当局部变量不用VAR时，为全局；function内可以再有finction定义;
js依赖于HTML，但不必写在HTML中，而是在HTML运行过程中运行一次JS即可,且可用于后面运行的JS；
arguments是传入参数数组，由JS本身提供；
aa={"aa":"aa"},bb={"bb":"bb"};jQuery.extend = jQuery.fn.extend = function() {... //js中可以连续赋值；
$.extend(cc,aa,bb);//aa,bb都赋给cc,cc是引用传值，cc必须有值(如{},此与java同),bb中的键如与aa重复，则在cc中覆盖，但aa,bb本身并不改变；
callbackContext instanceof jQuery,typeof(obj)=="function"//instanceof定位具体对象,typeof定位大类如function,object等;
function内的this指向其定义的对象(如window或一个自定义的对象，具体是调用其的实例),与JAVA同；
$.ajaxSetup设置调用Ajax的全局对对象时，如果在调用ajax时已指定事件响应的function,则不会再响应$.ajaxSetup中的设置；
json里的键可以不用引号，但有空格等特殊字符时要用引号，取值时可用对象.键取出；
$==jQuery,jQuery.fn==jQuery.prototype //true;jQuery是function,jQuery.prototype是object;window.jQuery = window.$ = jQuery;
http://www.csdn.net/article/2012-02-27/312402 js面向对象,但object与function还是有区别的;
http://www.csdn.net/article/2012-01-10/310412 js面向对象
http://www.csdn.net/article/2012-01-10/310412?1330304904
http://www.csdn.net/article/2012-11-14/2811887-writing-fast-memory-efficient-javascript
js中||可代？：，而&&可代if赋值；
$("#jsTesthtml2").load("b.html");//load指向其定义时对象$.fn,包括[0](html对象),context，版本号等；
扩展的方式：扩展成其它对象，实例修改(java不可改类型，JS可以)，值修改，动态接受外部设置等；
http://blog.csdn.net/javablogs/article/details/8886393 jQuery解析
\w,[]等正则只多个字符匹配单个字符，如要匹配多个要用限定符,如*,如果前面的正则包含了后面，则前面的自动缩小范围，如下面的rscript;
，单词可以结合\b直接写但在[]中用\b表示退格；转义符是\不是/,如\\,[^s]+[^r]+[^c]+不匹配src,也可以用(?!)
var ss = "Is is the is is cost of of gasoline going up up?./n";var re = /\b([a-z]+) \1\b/gim;var rv = ss.replace(re," aa($1) "); //()正则的运用
var rscript = /<script\b[^<]+src[\s]*=([\s]*[^\s]+[\s]*)[^<]+<\/script>/gi;responseText.replace(rscript,'<script type="text\/javascript" charset="utf-8" >aa($1);<\/script>')
非排除如[\s]+不适用范围自动缩小,而像^排除及*?等可以为0的则适用，do(defer|async)?当去掉do时只适用(或默认)+，可以用(defer|async|[^\w"'\s-=])，正则的test须在replace前，否则导致if(false),如：
/<script\b[^>]+src[\s]*=[\s]*['"]?([^\s]+)[\s]*[^>]*[\s]*(defer|async|[^\w"'\s-=])[^>]*>[\s]*<\/script>/gi;
$.fn.adsfa只要前面的对象有定义，则不会报未定义错误，而是undefined值；
trigger触发，fire具体调用引用中的方法；
一个JS对象不但可以赋JSON值，也可以赋数组值：var aaa1={aa:"AA",bb:"bb"};aaa1[aa]="aA";
不但静态资源可以缓存，动态数据也是一样的可以；
ajaxSettings是设置上下文，包括xhr,但与定义在ajax方法内的jqXHR不同;
正则启用：/^\+/.test( dataType )或new RegExp('services/jalor/registry').test(this.url)或其它方式如"asfd".replace(/../,"");
js形与实参可以不同类型与数量，不适用重载;但适用重写,多了可区别，少了不好区别;
js或java调试时输入的值或表达式会作用于每次调试;
function Person(name,age)
{
this.name=name;
this.age=age;
}
function Student(name,age,grade)
{
Person.call(this,name,age);//call,apply都是静态调用,参数写法不同,apply可用于继承,动态切换对象,参数一次传入等场所;
//Person.apply(this,arguments);//Person成为父类,但Person并未实例化,其对象化(prototype)也无改变,只是反射借用,并不改变两者原来的关系,
//第一个参数为上下文，动态改变不同对象而调用不同方法，可作动态反射
this.grade=grade; //会进入对象的实例属性中(this代表实例)，{}实际是直接定义了一个对象的实例；
var a1=5;//局部变量，不进入实例,但不进入对象(prototype,实例公共);
}
//创建一个学生类
var student=new Student("qian",21,"一年级"); //new让方法内的this不现指向window,而是student,也让Student有了个名为constructor的构造方法(运行时产生)，此方法为prototype性质，this在实例中指向定义其的实例，在方法中指向创建的实例,即this指向实例,typeof(Student) is"function",student is object {}is object,js中function实际为对象(类)
student.aa=5;//向实例增加属性;与java的先定义后使用不同;
Student.prototype.aa=3;//向对象增加属性;
//测试
alert("name:"+student.name+"\n"+"age:"+student.age+"\n"+"grade:"+student.grade);
async是html5中的，defer是4.0且IE中的；
string.substring(from, to),string.substr(start, length),string.slice(start, end),当参数为正整数时subsgring与slice一样的;
用document.createElement或write等动态引入的JS文件,浏览器会异步加载,但不是xhr,而是http;
$(document).bind("click",function(){alert("asdf");});document.onclick=function(){}
eclipse多核支持：-XX:+UseParallelGC,内存最大值应>512,如-Xmx1024m
b.push(a.disk1=function dd1(){alert("override:"+this.disk1);});
//a.disk1();//覆盖之前的a,disk1
var b=[]...,b=c=d;可连续并反向赋值,即如果任何一个无值或少值,则值最多的赋给它,与java异
b.push(a.disk=function dd(){//a.disk,dd,b[0](),dd()四个互不影响的方法,数组中的this指向数组而不是a;
HyperSnap 6.13.02,图片中取文字
smartclient的isc.B.push的时候如,isc.A.Date=function isc_isA_Date(object)，一般isc_c_Canvas_(非isc_Canvas_,也不是像isc_c_Canvas__的私有压缩后可变)function名(下划线改点)可用于定义后访问,如isc.isA.Date(...),如有重名定义，因方法名不同而在装载时应用成不同对象;
这样也产生了类的方法的可见性的私有公有限制;但加载调试的相关JS时是可以访问私有的方法;isc_Canvas_一般用于其它对象，如用于isc.Button等;isc.Canvas._setImageURL在调试与布署不同,调度时鼠标移动事件都调用,布署时只样式要改变时调用;
HTML中元素性性设置的优先级低于样式,如width;
<img src='imgs/wbs_export_excle.png' width='16' height='16'会产生缩放;
java:File file = new File(srcImagePath);String fileName=file.getName();if(null==type){type=fileName.substring(fileName.lastIndexOf(".")+1);}
BufferedImage src = javax.imageio.ImageIO.read(file);BufferedImage tag = new BufferedImage(width,height, BufferedImage.TYPE_INT_RGB);
Graphics g = tag.createGraphics();g.fillRect(0, 0, width, height);//否则边框带粗体色g.setClip(0, 0, width, height);tag.getGraphics().drawImage(src, 0, 0, width,
height, null);//src.getScaledInstance(w0/8, h0/8, Image.SCALE_SMOOTH)g.dispose();//out = new FileOutputStream(toImagePath);
//JPEGImageEncoder encoder = JPEGCodec.createJPEGEncoder(out);//可能不可有//encoder.encode(tag);ImageIO.write(tag, type, new File(toImagePath));
(function (value){ alert(value); }('value'));//匿名调用
isc.A.getImgURL=function isc_c_Canvas_getImgURL(src,imgDir,instance){//事件中调用,开始用imgHTML,并不走这里;
if(src==null||isc.isAn.emptyString(src))return isc._emptyString;
instance=instance||this.getPrototype();
if(src.imgDir!=null&&imgDir==null)imgDir=src.imgDir;
if(src.src!=null)src=src.src;
if(imgDir==null){
imgDir=(isc.startsWith(src,this._skinPrefix)?instance.skinImgDir:instance.appImgDir);//instance就是isc.A(this),_setImageURL中的imageElement对象也是this._handle中取得;
}//此处this是对一段HTML如DIV(一个控件)的封装,_handle是其中属性,里面还有document对象以及从isc.A的很多对象中继来的非私有属性;this指向实例对象Canvas而不是定义对象,isc.A;isc.A.stateChanged=function isc_StretchImg_stateChanged(whichPart)
//StretchImg对象用_handle持有的html中的图片名称才是源，并用getImage,setImage调用_handle中的HTML而不是isc.Canvas.imgHTML,_handle是在调isc_Canvas__insertHTML或者是通过this.ns从isc.Class.createRaw(isc_c_Class_createRaw记有ID)中赋值,
//StretchImg对象或方法是在push时基于反射或isc.defineClass创建的，this有src属性但不一定是真实的,可以基于此并结合handle动态拼装不同真实的图片,StretchImg继StatefulCanvas调this.getURL(isc_StatefulCanvas_getURL);
//isc.A.getURL=function isc_StatefulCanvas_getURL:getURL作调用名StatefulCanvas作对象名,isc.A.getURL是局部的,对类的创建作了统一处理;
var URL=isc.Page.getImgURL(src,imgDir);//得到http开始的全路径，并解析[skins]
return URL;}//元素name不要随意改,会用name找一些元素如按钮等;因_handle是源，所以修改imgHTML不会影响_handle及事件中的对象;事件中的HTML与imgHTML中的HTML是标;
img的src没改变或赋同样的值时,即使本地无些图象也不会再请求;
css与JS不同,当用AJAX请求CSS后还要innerHTML到页面,而JS则只请求即可;
return个般只作用于方法内部,循环中用return结束内外循环,而break只结束本循环,两者都只作用于循环内部;smartclient中的[].find不支持string,只支持对象;但add没限制;
css的className如果不存在，则不会有影响;
http默认是支持长连接的,一个页面可能有多个请求,所以可以类似socket实现实时效果;
导入JS无权限可能是跨域引起的，也可能其它原因,如jQuery.load就不支持子页面用document.write,这导致页面重绘;
$.ajax支持本地文件;jQuery.html会运行script标签内的脚本,但innerHTML不会;$("table").delegate("td", "hover", function(){}可用用每个td;不加var则默认全局;
eclipse配制Tomcat工作目录为eclipse的code目录(非create a new local sever),应配制preferences->Mongrel,另外conf\catalina\localhost中新建一个xml,<Context docBase=指定到WebContent目录,如果目录错误,导致调试,文件读写等等错误。
其它还可配一些<Resource指定jdbc,mail,javax.naming.spi.ObjectFactory(java.net.URL)等供web.xml中"<resource-ref id="引用.另外java:comp/env/mail/aaaSession提供给org.springframework.jndi.JndiObjectFactoryBean的jndiName使用;也可由jms提供;
StringBuffer并不因为是局部变量每次都new下而创建一个线程,本身并不占一个独立线程,故一般用局部的StringBuffered.除非同步代码块能让同实例同步;
可以在html标签内加自定义属性,然后在css中解析;xml配的bean要有setter,而注解配的则无需.静态html:模板或脚本动态生成或缓存;
static <T extends IEventHandler<E>, E extends IEventArgs> void dispatch(Class<T> handlerClass, E args, boolean ignoreError),也可用于类或属性定义上,extends是可选的。
mybatis中用#变量，而$导致sql注入;覆盖org.springframework.beans.factory.xml.AbstractSingleBeanDefinitionParser的doParse(A)及extends org.springframework.beans.factory.xml.NamespaceHandlerSupport,并实现init方法，可以扩展Ioc的elementname(xx:yy),
如：registerBeanDefinitionParser(elementName(如jms:listener-container),new A());js中0当作false,与c同;
jQuery中的选择器与筛选有些是重复的,如first;$("div .wbs_export_excle_new:first"),但放在find中是不需要空格的;log4j是异步的不是实时的;
