javascript 畫三角形

許久不見的三角形

for(var i=0;i<10;i++){
   for(var d=0;d < 10-i;d++){
    document.write("　");
   }
 for(var k=0;k<2*i-1;k++){
   document.write("★");
 }

 document.write("<br/>");

}
var c=2
for(var i=9;i>0;i--){

 for(var k=0;k<c;k++){
   document.write("　");
 }
 for(var k=0;k<2*i-3;k++){
   document.write("☆");
 }
 c++;
 document.write("<br/>");
}

Ibatis+Spirng配置

1.properties //dblink實際參數

 
<bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
 <property name="location" value="classpath:專案目錄/spring.properties" />
</bean>

2.dblink 配合properties

<bean id="testDataSource" class="org.apache.commons.dbcp.BasicDataSource">
 <property name="driverClassName" value="${test_driverClassName}" />
 <property name="url" value="${test_url}" />
 <property name="username" value="${test_username}" />
 <property name="password" value="${test_password}" />
 <property name="testWhileIdle" value="true"/>
 <property name="validationQuery" value="select 1 from dual"/>
 <property name="logAbandoned" value="true"/>
 <property name="removeAbandoned" value="true"/>
 <property name="removeAbandonedTimeout" value="3600"/>
 <property name="maxWait" value="20"/>
 <property name="maxIdle" value="10"/>
 <property name="maxActive" value="-1"/>
 <property name="accessToUnderlyingConnectionAllowed" value="true"/>
 <bean id="nativeJdbcExtractor" class="org.springframework.jdbc.support.nativejdbc.CommonsDbcpNativeJdbcExtractor" 
  lazy-init="true" />
<bean id="oracleLobHandler" class="org.springframework.jdbc.support.lob.OracleLobHandler" lazy-init="true"> 
 <property name="nativeJdbcExtractor"> 
     <ref local="nativeJdbcExtractor" /> 
 </property>
</bean>  
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> 
      <property name="dataSource" ref="testDataSource"/>
</bean>

3.讀取sqlmapconfig

<bean id="sqlMapClient" class="org.springframework.orm.ibatis.SqlMapClientFactoryBean">
   <property name="dataSource" ref="dataSource"/>
   <property name="configLocation">
       <value>classpath:專案目錄/SqlMapConfig.xml</value>
   </property>
   <property name="transactionConfigProperties">
       <props>
           <prop key="DefaultAutoCommit">false</prop>
       </props>
   </property>
        <property name="lobHandler">
      <ref local="oracleLobHandler" />
  </property>
  </bean> 

4.java 讀取dao

  
 <bean id="sqlMapClientTemplate" class="org.springframework.orm.ibatis.SqlMapClientTemplate">
   <property name="sqlMapClient" ref="sqlMapClient" />
   <property name="exceptionTranslator">
       <bean class="org.springframework.jdbc.support.SQLErrorCodeSQLExceptionTranslator">
           <property name="dataSource" ref="dataSource" />
       </bean>
   </property>
</bean>
 <bean id="ibatisDAOProxy" class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean">
   <property name="transactionManager">
       <ref bean="transactionManager"/>
   </property>
   <property name="target">
       <ref bean="baseIbatisDao"/>
   </property>
   <property name="transactionAttributes">
       <props>             
           <prop key="*">PROPAGATION_REQUIRED,-Exception</prop>
       </props>
   </property>    
 </bean>

String prototype

網路上找到對於prototype的定義、以下是我從字面翻過來的

"javascript既有對像都只有讀的prototype屬性。

只能為原型添加功能，但不能被賦予不同的原型。

但是定義的對象可以被賦給新的原型。"

常用如下:

String.prototype.trim = function() {

return this.replace(/(^\s*)|(\s*$)/g, "");

}

// 全部取代指定字串

String.prototype.replaceAll = function (str1,str2) {

return this.replace(new RegExp(str1,"gm"),str2);

};

// 移除Array指定筆數

Array.prototype.remove = function (i) {

return this.splice(i,1);

};

JavaScript String 多種用法

以下這些在coding的過程滿常需要用到、在這裡做個紀錄

string data="test"

data.******()

.toString()

.length

.charAt()

.lastIndexOf()

.indexof()

.replace()

.split()

.slice(start(略),end((略)) //截斷取出

.fontcolor("Red")

.toLowerCase()

.toUpperCase()

.sub()//上標

.sup() //下標

.link("www.google.com")

.big()

.small()

.bold()

.italics()

.strike()

Ireport 中文粗體

將要顯示粗體的中文字(kaiu.ttf)的字體改 Arial Narrow、則在ireport中勾選粗體才有作用

Map fontsMap = new HashMap ();

fontsMap.put(new FontKey("Arial Narrow", true, false),

new PdfFont(dir+File.separator+"kaiu.ttf", "Identity-H", true, true, false));

fontsMap.put(new FontKey("標楷體", true, false),

new PdfFont(dir+File.separator+"kaiu.ttf", "Identity-H", true, false, false));//設置字體樣式

exporter.setParameter(JRExporterParameter.FONT_MAP, fontsMap);

ireport [sub report]

1.讀取mainReport

JasperReport jasperReport = JasperCompileManager.compileReport("C:\\Temp\\report2.jrxml");

2.先將sub.jasper讀進來、存放至主要的HashMap mapParameter = new HashMap();

InputStream stream1 = getRequest().getSession().getServletContext().getResourceAsStream("xxxxxxxx_subreport_Net.jasper");

JasperReport netReport = (JasperReport) JRLoader.loadObject(stream1);

//map key 對應subReport Name

mapParameter.put("NET_REPORT", netReport);

3.subReport 資料型態 JRMapCollectionDataSource(ArrayList<HashMap>)<

在此命 為NetProduct>後續irport會用

放置mapParameter.put("Report_Net_list", NetProduct());

4.JasperPrint jasperPrint = JasperFillManager.fillReport( jasperReport, a,new JREmptyDataSource());

new JREmptyDataSource也是實作implements JRDataSource 、

如果沒有JRDataSource、null值必需塞new JREmptyDataSource不能放置null或空值

5.iReport設置

(1)新增(NET_REPORT)parameter:net.sf.jasperreports.engine.JasperReport

用意在於java先讀取jaxml或jasper檔在傳給ireport

(2)新增(Report_Net_list)Parameter:net.sf.jasperreports.engine.data.JRMapCollectionDataSource

(2)Expression class :net.sf.jasperreports.engine.JasperReport

Data Source Expression:放置之前java設置的Report_Net_list( JRMapCollectionDataSource)

附上test Code &JAR檔

jQuery ajax方式

var params = {

keyValue : '對應GetDateTagKey',

inputValue : '輸入值'};

var url = '../tag/getDataTag.action';

jQuery.ajax({

type:"POST",

dataType:"json",

async:false, // true:異步,false:同步

url:url,//目標url

data:params,//也可綁定action

beforeSend:function(){},//送出前執行

success:function(json){

var data = eval(json);

if(data != null){

custType.options.length = 0;

for(var i = 0 ; i < data.length ; i++){

custType.options[i] = new Option(data[i].dscr, data[i].lookup_code);

}

}else{

alert("取得失敗");

}

},

error:function(){

alert("取得異常");

}

});
